Estuary
–
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a zone between river environments and maritime environments. They are subject both to marine influences—such as tides, waves, and the influx of saline water—and to riverine influences—such as flows of fresh water and sediment. The inflows of sea water and fresh water provide high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea began to rise about 10. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns, the banks of many estuaries are amongst the most heavily populated areas of the world, with about 60% of the worlds population living along estuaries and the coast. The word estuary is derived from the Latin word aestuarium meaning tidal inlet of the sea, there have been many definitions proposed to describe an estuary. However, this definition excludes a number of water bodies such as coastal lagoons. This broad definition also includes fjords, lagoons, river mouths, an estuary is a dynamic ecosystem having a connection to the open sea through which the sea water enters with the rhythm of the tides. The sea water entering the estuary is diluted by the water flowing from rivers. The pattern of dilution varies between different estuaries and depends on the volume of water, the tidal range. Drowned river valleys are known as coastal plain estuaries. In places where the sea level is rising relative to the land, sea water progressively penetrates into river valleys and this is the most common type of estuary in temperate climates. Well-studied estuaries include the Severn Estuary in the United Kingdom and the Ems Dollard along the Dutch-German border, the width-to-depth ratio of these estuaries is typically large, appearing wedge-shaped in the inner part and broadening and deepening seaward. Water depths rarely exceed 30 m, examples of this type of estuary in the U. S. are the Hudson River, Chesapeake Bay, and Delaware Bay along the Mid-Atlantic coast, and Galveston Bay and Tampa Bay along the Gulf Coast. They are relatively common in tropical and subtropical locations and these estuaries are semi-isolated from ocean waters by barrier beaches. Formation of barrier beaches partially encloses the estuary, with only narrow inlets allowing contact with the ocean waters, bar-built estuaries typically develop on gently sloping plains located along tectonically stable edges of continents and marginal sea coasts. They are extensive along the Atlantic and Gulf coasts of the U. S. in areas with active coastal deposition of sediments, barrier beaches form in shallow water and are generally parallel to the shoreline, resulting in long, narrow estuaries

San Francisco Bay
–
San Francisco Bay is a shallow estuary in the U. S. state of California. It is surrounded by a region known as the San Francisco Bay Area, dominated by the large cities San Francisco, Oakland. San Francisco Bay drains water from approximately 40 percent of California and it then connects to the Pacific Ocean via the Golden Gate strait. However, this group of interconnected bays is often called the San Francisco Bay. The bay was designated a Ramsar Wetland of International Importance on February 2,2013, the bay covers somewhere between 400 and 1,600 square miles, depending on which sub-bays, estuaries, wetlands, and so on are included in the measurement. The main part of the bay measures 3 to 12 miles wide east-to-west and it is the largest Pacific estuary in the Americas. Later, wetlands and inlets were filled in, reducing the Bays size since the mid-19th century by as much as one third. Recently, large areas of wetlands have been restored, further confusing the issue of the Bays size, despite its value as a waterway and harbor, many thousands of acres of marshy wetlands at the edges of the bay were, for many years, considered wasted space. As a result, soil excavated for building projects or dredged from channels was often dumped onto the wetlands, from the mid-19th century through the late 20th century, more than a third of the original bay was filled and often built on. The idea was, and remains, controversial, there are five large islands in San Francisco Bay. Alameda, the largest island, was created when a shipping lane was cut in 1901 and it is now predominantly a bedroom community. Angel Island was known as Ellis Island West because it served as the point for immigrants from East Asia. It is now a park accessible by ferry. Mountainous Yerba Buena Island is pierced by a tunnel linking the east and west spans of the San Francisco–Oakland Bay Bridge, attached to the north is the artificial and flat Treasure Island, site of the 1939 Golden Gate International Exposition. From the Second World War until the 1990s, both served as military bases and are now being redeveloped. Isolated in the center of the Bay is Alcatraz, the site of the federal penitentiary. The federal prison on Alcatraz Island no longer functions, but the complex is a popular tourist site, despite its name, Mare Island in the northern part of the bay is a peninsula rather than an island. During the last ice age, the now filled by the bay was a large linear valley with small hills

East Bay (San Francisco Bay Area)
–
The eastern region of the San Francisco Bay Area, commonly referred to as the East Bay, includes cities along the eastern shores of the San Francisco Bay and San Pablo Bay. The region has grown to include inland communities in Alameda and Contra Costa Counties, with a population of roughly 2.5 million in 2010, it is the most populous subregion in the Bay Area. Oakland is the largest city in the East Bay and the third largest in the Bay Area, the city serves as a major transportation hub for the U. S. West Coast, and its port is the largest in Northern California, increased population has led to the growth of such large edge cities as Berkeley, Hayward, Concord and Fremont. The Transcontinental Railroad was completed in 1869 with its terminus at the newly constructed Oakland Long Wharf. Today the Port of Oakland is the Bay Areas largest port, in 1868, the University of California was formed from the private College of California and a new campus was built in what would become Berkeley. The 1906 San Francisco earthquake saw a number of refugees flee to the relatively undamaged East Bay. As the East Bay grew, the push to connect it with a permanent link than ferry service resulted in the completion of the San Francisco–Oakland Bay Bridge in 1936. The Bay Area saw further growth in the decades following World War II, the 1937 completion of the Caldecott Tunnel through the Berkeley Hills fueled growth further east, where there was undeveloped land. Cities in the Diablo Valley, including Concord and Walnut Creek, the addition of the BART commuter rail system in 1972 further encouraged development in increasingly far-flung regions of the East Bay. Today, the valleys east of the Berkeley Hills contain large affluent suburban communities such as Walnut Creek, San Ramon, the East Bay is not a formally defined region, aside from its being described as a region inclusive of Alameda and Contra Costa counties. As development moves generally eastward, new areas are described as being part of the East Bay, beyond the borders of Alameda County, the large population of Tracy is connected as a bedroom community housing commuters traveling to or through the East Bay. Except for some hills and ridges which exist as parklands or undeveloped land, and some farmland in eastern Contra Costa and Alameda Counties, the East Bay is highly urbanized. The East Bay shoreline is a corridor with several cities exceeding 100,000 residents, including Oakland, Hayward, Fremont, Richmond. In the inland valleys on the east side of the Berkeley Hills, the land is developed, particularly on the eastern fringe of Contra Costa county. In the inland valleys, the density is less and the cities smaller. The only cities exceeding 100,000 residents in the valleys are Antioch. The free East Bay Monthly has been published since 1970, in the early years of the evolution of USA Today, during the early 1980s, they operated regional newspapers, with the regions paper entitled East Bay Today

North Bay (San Francisco Bay Area)
–
The North Bay is a subregion of the San Francisco Bay Area, in California, United States. The largest city is Santa Rosa, which is the fifth-largest city in the Bay Area and it is the location of the Napa and Sonoma wine regions, and is by far the least populous and least urbanized part of the Bay Area. It consists of Marin, Napa, Solano, and Sonoma counties, several ferry routes operate between the North Bay and San Francisco, from terminals located in Sausalito, Tiburon, Larkspur, Vallejo and Angel Island. Commuter rail service from Fairfield to Sacramento and Oakland is provided by Amtrak on its Capitol Corridor line, plans for the development of the Sonoma-Marin Area Rail Transit, a fourteen station commuter rail line from Larkspur to Cloverdale, were approved by voters in November 2008. The area is said to have populated by Pomo Native Americans before European intervention. The Russians first settled the area at Fort Ross as a fur-trading post, the Bear Flag Revolt took place in the town of Sonoma, which is also the location of the last of the California Missions. The North Bay remained isolated and rural well into the 20th Century, the opening of the Golden Gate Bridge in the 1930s transformed Marin County from a dairy farming region into an upscale suburban area. Until the 1990s, the growth was at a gradual pace, with significant restrictions on development being imposed in Marin. The largest city in the North Bay is Santa Rosa, other major cities include, Vallejo San Rafael Fairfield Napa Novato Petaluma Rohnert Park North Coast AVA North Coast San Pablo Bay National Wildlife Refuge

San Francisco Bay Area
–
The San Francisco Bay Area is a populous region surrounding the San Francisco and San Pablo estuaries in Northern California. The region encompasses the cities and metropolitan areas of San Jose, San Francisco. The Bay Areas nine counties are Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, and Sonoma. The combined statistical area of the region is the second-largest in California, the fifth-largest in the United States, the Bay Area has the second-most Fortune 500 Companies in the United States, and is known for its natural beauty, liberal politics, entrepreneurship, and diversity. The eastern side of the bay, consisting of Alameda and Contra Costa counties, is known locally as the East Bay, the inner East Bay is more densely populated, with generally older buildings, and a more ethnically diverse population. The word Lamorinda was coined by combining the names of the cities it includes, Lafayette, Moraga, walnut Creek is situated east of Lamorinda and north of the San Ramon Valley and, together with Concord, Martinez, and Pleasant Hill comprises Central Contra Costa County. The cities of Antioch, Pittsburg, Brentwood, Oakley and the areas surrounding them comprise East Contra Costa County. The Tri-Valley consists of the Amador, the Livermore, and the San Ramon Valleys, dublin and Pleasanton comprise the Amador Valley, Livermore lies in the Livermore Valley, and the San Ramon Valley consists of Alamo, Danville, Diablo and its namesake, San Ramon. The outer East Bay is connected to the inner East Bay by BART, Interstate 580 to the south, and State Routes State Route 4 to the north, the outer East Bays infrastructure was mostly built up after World War II. This area remains largely white demographically, although the Hispanic and Filipino populations have grown significantly over the past 2–3 decades, the region north of the Golden Gate Bridge is known locally as the North Bay. This area encompasses Marin County, Sonoma County, Napa County, the city of Fairfield, being part of Solano County, is often considered the easternmost city of the North Bay. With few exceptions, this region is affluent, Marin County is ranked as the wealthiest in the state. The North Bay is relatively rural compared to the remainder of the Bay Area, with areas of undeveloped open space, farmland. Santa Rosa in Sonoma County is the North Bays largest city, with a population of 167,815 and a Metropolitan Statistical Area population of 466,891, making it the fifth-largest city in the Bay Area. The North Bay is the section of the Bay Area that is not currently served by a commuter rail service. The area from San Francisco to the Silicon Valley, geographically part of the San Francisco Peninsula, is known locally as The Peninsula, many of these families are of foreign background and have significantly contributed to the diversity of the area. Whereas the term peninsula technically refers to the entire geographical San Franciscan Peninsula, in local terms, San Francisco is surrounded by water on three sides, the north, east, and west. The city squeezes roughly 870,000 people in under 47 square miles, on any given day, there can be as many as 1 million people in the city because of the commuting population and tourism

California
–
California is the most populous state in the United States and the third most extensive by area. Located on the western coast of the U. S, California is bordered by the other U. S. states of Oregon, Nevada, and Arizona and shares an international border with the Mexican state of Baja California. Los Angeles is Californias most populous city, and the second largest after New York City. The Los Angeles Area and the San Francisco Bay Area are the nations second- and fifth-most populous urban regions, California also has the nations most populous county, Los Angeles County, and its largest county by area, San Bernardino County. The Central Valley, an agricultural area, dominates the states center. What is now California was first settled by various Native American tribes before being explored by a number of European expeditions during the 16th and 17th centuries, the Spanish Empire then claimed it as part of Alta California in their New Spain colony. The area became a part of Mexico in 1821 following its war for independence. The western portion of Alta California then was organized as the State of California, the California Gold Rush starting in 1848 led to dramatic social and demographic changes, with large-scale emigration from the east and abroad with an accompanying economic boom. If it were a country, California would be the 6th largest economy in the world, fifty-eight percent of the states economy is centered on finance, government, real estate services, technology, and professional, scientific and technical business services. Although it accounts for only 1.5 percent of the states economy, the story of Calafia is recorded in a 1510 work The Adventures of Esplandián, written as a sequel to Amadis de Gaula by Spanish adventure writer Garci Rodríguez de Montalvo. The kingdom of Queen Calafia, according to Montalvo, was said to be a land inhabited by griffins and other strange beasts. This conventional wisdom that California was an island, with maps drawn to reflect this belief, shortened forms of the states name include CA, Cal. Calif. and US-CA. Settled by successive waves of arrivals during the last 10,000 years, various estimates of the native population range from 100,000 to 300,000. The Indigenous peoples of California included more than 70 distinct groups of Native Americans, ranging from large, settled populations living on the coast to groups in the interior. California groups also were diverse in their organization with bands, tribes, villages. Trade, intermarriage and military alliances fostered many social and economic relationships among the diverse groups, the first European effort to explore the coast as far north as the Russian River was a Spanish sailing expedition, led by Portuguese captain Juan Rodríguez Cabrillo, in 1542. Some 37 years later English explorer Francis Drake also explored and claimed a portion of the California coast in 1579. Spanish traders made unintended visits with the Manila galleons on their trips from the Philippines beginning in 1565

In 2002, the Civil Rights Project at Harvard University conducted for Time magazine named Sacramento Americas Most Diverse City, Sacramento became a city through the efforts of the Swiss immigrant John Sutter, Sr. his son John Augustus Sutter, Jr. and James W. Marshall. Sacramento grew quickly thanks to the protection of Sutters Fort, which was established by Sutter in 1839, the city was named after the Sacramento River, which forms its western border. The river was named by Spanish cavalry officer Gabriel Moraga for the Santísimo Sacramento, California State University, Sacramento, is the largest university in the city and one of 23 campuses in the California State University system. University of the Pacific is a university with one of its three campuses in Sacramento. In addition, the University of California, Davis, located in nearby Davis, operates its UC Davis Medical Center, nisenan and Plains Miwok Native Americans had lived in the area for perhaps thousands of years. Unlike the settlers who would eventually make Sacramento their home, these Native Americans left little evidence of their existence. Traditionally, their diet was dominated by acorns taken from the oak trees in the region, and by fruits, bulbs, seeds. In 1808, the Spanish explorer Gabriel Moraga discovered and named the Sacramento Valley, a Spanish writer with the Moraga expedition wrote, Canopies of oaks and cottonwoods, many festooned with grapevines, overhung both sides of the blue current. Birds chattered in the trees and big fish darted through the pellucid depths, the air was like champagne, and drank deep of it, drank in the beauty around them. The valley and the river were then christened after the Most Holy Sacrament of the Body and Blood of Christ, John Sutter first arrived on August 13,1839 at the divergence of the American and Sacramento Rivers with a Mexican land grant of 50,000 acres. The next year, he and his party established Sutters Fort, representing Mexico, Sutter called his colony New Helvetia, a Swiss inspired name, and was the political authority and dispenser of justice in the new settlement. Soon, the colony began to grow as more and more pioneers headed west, within just a few short years, John Sutter had become a grand success, owning a ten-acre orchard and a herd of thirteen thousand cattle. Fort Sutter became a stop for the increasing number of immigrants coming through the valley. In 1847, Sutter hired James Marshall to build a sawmill so that he could continue to expand his empire, Sutter received 2,000 fruit trees in 1847, which started the agriculture industry in the Sacramento Valley. In 1848, when gold was discovered by James W. Marshall at Sutters Mill in Coloma and he hired topographical engineer William H

It was a centuries-old Native American footpath that lead through the Sacramento Valley over the Cascades, Gold rush era Europeans and Americans started to arrive in the area after gold was found in northern California, starting with the California Gold Rush in 1848. When Captain Charles Maria Weber, a German immigrant, decided to try his hand at mining in late 1848. As an alien, Weber could not secure a land grant directly, born in New York, Gulnae had married a Mexican woman and sworn allegiance to Mexico, which then ruled California.

Ranchos of California
–
The Spanish and later Mexican governments encouraged settlement of Alta California by giving prominent men large land grants called ranchos, usually two or more square leagues. Land-grant titles were government-issued, permanent, unencumbered property-ownership rights to land called ranchos, devoted to raising cattle and sheep, the owners of the ranchos attempted to pattern themselves after the landed gentry of Spain. Their workers included Californian Native Americans who had learned to speak Spanish, Spain made about 30 grants between 1784 and 1821, and Mexico granted about 270 more between 1833 and 1846. The ranchos established land-use patterns and place names that are still in use in California today, Rancho boundaries became the basis for Californias land survey system, and can still be found on modern maps and land titles. Ranchos were partially based on geography, such as access to river water, Land development in the 20th and 21st century often follow the boundaries of the ranchos, and often retain the original name. For example, Rancho San Diego, an unincorporated rural-burb east of San Diego, or Rancho Bernardo, during Spanish rule, the ranchos were concessions from the Spanish crown, permitting settlement and granting grazing rights on specific tracts of land, while the crown retained the title. The land concessions were usually measured in leagues, a league of land would encompass a square that is one Spanish league on each side – approximately 4,428 acres. The Spanish and Mexican governments made a number of grants from 1785 to 1846. It was not until the Mexican era that the titles to the plots of land were granted to individuals, in 1821, Mexico achieved its independence from Spain, and California came under control of the Mexican government. The 1824 Mexican Colony Law established rules for petitioning for land grants in California, and by 1828, the Acts sought to break the land monopoly of the missions and also paved the way for luring additional settlers to California by making land grants easier to obtain. Secularization was implemented between 1834 and 1836, the Mexican government allowed the padres to keep only the church, priests quarters and priests garden. The army troops guarding each Mission were dismissed, a commissioner would oversee the missions crops and herds, while the land was divided up as communal pasture, a town plot, and individual plots for each Indian family. The Mission Indians, freed from the missions, often joined other tribes or sought work on the new ranchos along the troops formerly assigned to each mission. The number of Mexican land grants greatly increased after the secularization of the missions in 1834, the Mexican rancho grants were provisional. The boundaries, on paper, had to be surveyed and marked. This produced a diseño, a topological map, to define the area. Since there were very few surveyors this requirement was seldom met, the grantee could not initially subdivide or rent out the land. The land had to be used for grazing or cultivated, some kind of residential house had to be built within a year—most were initially simple adobe walled cabins

Alta California
–
Alta California, founded in 1769 by Gaspar de Portolà, was a polity of New Spain and after the Mexican War of Independence in 1822, a territory of Mexico. The region included all of the states of California, Nevada, and Utah. Large areas east of the Sierra Nevada and San Gabriel Mountains were claimed to be part of Alta California, to the southeast, beyond the deserts and the Colorado River, lay the Spanish settlements in Arizona. The areas formerly comprising Alta California were ceded to the United States in the Treaty of Guadalupe Hidalgo that ended the Mexican–American War in 1848, two years later, California joined the union as the 31st state. Other parts of Alta California became all or part of the later U. S. states of Arizona, Nevada, Utah, Colorado, and Wyoming. The Spanish explored the area of Alta California by sea beginning in the 16th century. During the following two centuries there were plans to settle the area, none of which were effectively carried out. Ultimately, New Spain did not have the resources nor population to settle such a far northern outpost. To ascertain the Russian threat a number of Spanish expeditions to the Pacific Northwest were launched, the Spanish Crown funded the construction and subsidized the operation of the missions, with the goal that the relocation, conversion and enforced labor of Native people would bolster Spanish rule. The first Alta California mission and presidio were established by the Franciscan friar Junípero Serra, the following year,1770, the second mission and presidio were founded in Monterey. In 1773 a boundary between the Baja California missions and the Franciscan missions of Alta California was set by Francisco Palóu, the missionary effort coincided with the construction of presidios and pueblos, which were to be manned and populated by Hispanic people. The first pueblo founded was San José in 1777, followed by Los Ángeles in 1781, by law, mission land and property were to pass to the indigenous population after a period of about ten years, when the natives would become Spanish subjects. In the interim period, the Franciscans were to act as mission administrators who held the land in trust for the Native residents, the transfer of property never occurred under the Franciscans. As the number of Spanish settlers grew in Alta California, the boundaries, conflicts between the Crown and the Church and between Natives and settlers arose. State and ecclesiastical bureaucrats debated over authority of the missions and they advocated that the Natives owned property and had the right to defend it. Governor Diego de Borica is credited with defining Alta and Baja Californias official borders, Mexico won independence in 1822, and Alta California became a territory of Mexico. The Spanish and later Mexican governments rewarded retired soldados de cuera with large grants, known as ranchos, for the raising of cattle. Hides and tallow from the livestock were the primary exports of California until the mid-19th century, the construction, ranching and domestic work on these vast estates was primarily done by Native Americans, who had learned to speak Spanish and ride horses

San Pablo, California
–
San Pablo is a city in Contra Costa County, California, United States. The city of Richmond surrounds nearly the whole city, the population was 29,139 at the 2010 census. The current Mayor is Rich Kinney, and the current Vice Mayor is Paul V. Morris, current Council members include Cecilia Valdez, Kathy Chao Rothberg, and Rich Kinney. The area in which todays San Pablo is situated was originally occupied by the Cuchiyun band of the Ohlone indigenous people, the area was claimed for the king of Spain in the late 18th century and was granted for grazing purposes to the Mission Dolores located in todays San Francisco. The grant was given the name Rancho San Pablo, thus originating the name for todays city as well as for one of the East Bays oldest principal roads, todays San Pablo Avenue. Upon Gabriélas death in 1851, it was inherited by her daughter, Martina Castro de Alvarado, wife of Juan Bautista Alvarado, the Alvarado Adobe was demolished in the mid-20th century to make way for a motel. A reproduction was built later in the century which is located in the San Pablo Civic Center on the northwest corner of San Pablo Avenue and Church Lane. A single beam from the structure is incorporated into the roof of the replacement structure. The first post office was established in 1854, since the middle of the 20th Century College Center at El Portal has been the backbone of the communitys retail economy. According to the United States Census Bureau, the city has an area of 2.6 square miles. San Pablo lies on a plain between the northern end of the Berkeley Hills and San Pablo Bay, although the city limits do not extend to the bayshore. The city is traversed by two creeks, Wildcat Creek and San Pablo Creek, both of which originate in the ranges to its southeast. The minor Rheem Creek also runs through the city and it is also traversed along its northeast limits by the Hayward Fault, a major branch of the San Andreas Fault which lies to the west. Interstate 80 passes through San Pablo, there are several communities to the north of the City and separated from the City, but which have San Pablo, California mailing addresses. These include the areas of Tara Hills, Bayview. According to the Citys 2010 Comprehensive Annual Financial Report, the top employers in the city are, the 2010 United States Census reported that San Pablo had a population of 29,139. The population density was 11,063.4 people per square mile. The racial makeup of San Pablo was 9,391 White,4,600 African American,244 Native American,4,353 Asian,172 Pacific Islander,8,812 from other races, Hispanic or Latino of any race were 16,462 persons

Sacramento River
–
The Sacramento River is the principal river of Northern California in the United States, and is the largest river in California. Rising in the Klamath Mountains, the river flows south for 400 miles before reaching the Sacramento–San Joaquin River Delta, the Sacramento and its wide natural floodplain were once abundant in fish and other aquatic creatures, notably one of the southernmost large runs of chinook salmon in North America. For about 12,000 years, humans have depended on the vast natural resources of the watershed, the river has provided a route for trade and travel since ancient times. Hundreds of tribes sharing regional customs and traditions inhabited the Sacramento Valley, the Spanish explorer Gabriel Moraga named the river Rio de los Sacramentos in 1808, later shortened and anglicized into Sacramento. In the 19th century gold was discovered on a tributary of the Sacramento River, starting the California Gold Rush, overland trails such as the California Trail and Siskiyou Trail guided hundreds of thousands of people to the gold fields. By the late part of the mining had ceased to be a major part of the economy. Many populous communities were established along the Sacramento River, including the capital of Sacramento. Intensive agriculture and mining contributed to pollution in the Sacramento River, since the 1950s the watershed has been intensely developed for water supply and the generation of hydroelectric power. Today, large dams impound the river and almost all of its major tributaries, the Sacramento is used heavily for irrigation and serves much of Central and Southern California through the canals of giant state and federal water projects. The Sacramento River originates in the mountains and plateaus of far northern California as three major waterways that flow into Shasta Lake, the Upper Sacramento River, McCloud River and Pit River. The Upper Sacramento begins near Mount Shasta, at the confluence of North, Middle and it flows east into a small reservoir, Lake Siskiyou, before turning south. The river flows through a canyon for about 60 miles, past Dunsmuir and Castella, the Pit River, by far the largest of the three, begins in Modoc County in the northeastern corner of California. Draining a vast and remote volcanic highlands area, it flows southwest for nearly 300 miles before emptying into Shasta Lake near Montgomery Creek, Goose Lake, straddling the Oregon–California border, occasionally overflows into the Pit River during wet years, although this has not happened since 1881. The Goose Lake watershed is the part of the Sacramento River basin extending into another state. Unlike most California rivers, the Pit and the McCloud Rivers are predominantly spring-fed, ensuring a large, at the lower end of Shasta Lake is Shasta Dam, which impounds the Sacramento River for flood control, irrigation and hydropower generation. Before the construction of Shasta Dam the McCloud River emptied into the Pit River, the Pit River Bridge, which carries Interstate 5 and the Union Pacific Railroad over the reservoir, is structurally the highest double-decked bridge in the United States. The Upper Sacramento River canyon also provides the route for I-5, below Shasta Dam the Sacramento River enters the foothills region of the northern Sacramento Valley. It flows through Keswick Dam, where it receives about 1,200,000 acre feet of water per year diverted from the Trinity River and it then swings east through Redding, the largest city of the Shasta Cascade region, and turns southeast, entering Tehama County

San Joaquin River
–
The San Joaquin River /ˈsæn wɑːˈkiːn/ is the longest river of Central California in the United States. An important source of water as well as a wildlife corridor. People have inhabited the San Joaquin Valley for more than 8,000 years, the newcomers quickly appropriated the rich natural and hydrologic resources of the watershed for use in farms and cities, but found themselves plagued by flood and drought. Because of the topography of the San Joaquin Valley, floods once transformed much of the lower river into a huge inland sea. In the 20th century, many levees and dams were built on the San Joaquin and these engineering works changed the fluctuating nature of the river forever, and cut off the Tulare Basin from the rest of the San Joaquin watershed. The river was called many different names, at different parts of the river were known by different names. The present name of the dates to 1805–1808, when Spanish explorer Gabriel Moraga was surveying east from Mission San José in order to find possible sites for a mission. Moraga named a tributary of the river for Saint Joachim, husband of Saint Anne and father of Mary, the name Moraga chose was later applied to the entire river, it was in common use by 1810. In the Mono language, the river is called typici h huu, a member of the Pedro Fages party in 1772, Crespis vantage point was the hilltops behind modern San Francisco. Another early name was Rio San Juan Bautista, the origin of which is unknown.8 mi southeast of Mount Lyell, the Middle Fork is usually considered part of the main stem. The South Fork, which begins at Martha Lake in Kings Canyon National Park and flows through Florence Lake, from the mountainous alpine headwaters, the San Joaquin flows generally south into the foothills of the Sierra, passing through four hydroelectric dams. It eventually emerges from the foothills at what was once the town of Millerton, the location of Friant Dam since 1942, which forms Millerton Lake. Below Friant Dam, the San Joaquin flows west-southwest out into the San Joaquin Valley – the southern part of the Great Central Valley – passing north of Fresno, from Mendota, the San Joaquin swings northwest, passing through many different channels, some natural and some man-made. Northeast of Dos Palos, it is joined by the Fresno. Fifty miles downstream, the Merced River empties into an otherwise dry San Joaquin, the majority of the river flows through quiet agricultural bottomlands, and as a result its meandering course manages to avoid most of the urban areas and cities in the San Joaquin Valley. About 11 mi west of Modesto, the San Joaquin meets its largest tributary, near Vernalis, it is joined by another major tributary, the Stanislaus River. About 40 mi from the mouth, the river draws abreast to the flank of Stockton. From here to the mouth, the river is dredged as part of a navigation project, past the head of tide, amid the many islands of the delta, the San Joaquin is joined by two more tributaries, the Calaveras River and the larger Mokelumne

Suisun Bay
–
Suisun Bay is a shallow tidal estuary in northern California. It lies at the confluence of the Sacramento and San Joaquin Rivers, forming the entrance to the Sacramento–San Joaquin River Delta, Suisun Marsh, the tidal marsh land to the north, is the largest marsh in California. Grizzly Bay forms an extension of Suisun Bay. The bay is directly north of Contra Costa County, the bay was named in 1811, after the Suisunes, a Native American tribe of the area. The word originates with the Patwin, on the west, Suisun Bay is drained by the Carquinez Strait, which connects to San Pablo Bay, a northern extension of San Francisco Bay. In addition to the bridges at the Carquinez Strait, it is spanned in its center by the Benicia-Martinez Bridge. It is the anchorage of the Suisun Bay Reserve Fleet, a collection of U. S. Navy and merchant reserve ships, the Glomar Explorer was anchored here after recovering a sunken Soviet submarine in the mid-1970s. Many ships were removed and sold for scrap in the 1990s, in 2010, plans were announced to remove the mothball fleet in stages, with final removal by 2017. The Central Pacific Railroad built a ferry that operated between Benicia and Port Costa, California from 1879 to 1930. The ferry boats Solano and Contra Costa were removed from service when the nearby Martinez railroad bridge was completed in 1930, from 1913 until 1954 the Sacramento Northern Railway, an electrified interurban line, crossed Suisun Bay with the Ramon, a distillate-powered train ferry. Kinder Morgan pleaded guilty to operating a corroded pipeline and paid three dollars in penalties and restitution.

Carquinez Strait
–
The Carquinez Strait is a narrow tidal strait in northern California. It is part of the estuary of the Sacramento and the San Joaquin rivers as they drain into the San Francisco Bay. The strait connects Suisun Bay, which receives the waters of the rivers, with San Pablo Bay. The strait forms part of the border between Solano and Contra Costa counties, and is approximately 15 mi north of Oakland, the cities of Benicia and Vallejo lie on the north side of the strait, while Martinez, Port Costa, and Crockett sit on the southern coast. The Napa River joins the strait, via the short Mare Island Strait, the strait is named after the Karkin, a linguistic division of the Ohlone Native Americans who resided on both sides of the strait. The California Maritime Academy is at the end of the strait on the northern waterfront. The C&H Sugar refinery is located on the shore in the small town of Crockett. The strait is crossed by two bridges, the Carquinez Bridge on Interstate 80 and the Benicia-Martinez Bridge on Interstate 680. Each highway bridge consists of two spans, Interstate 780 connects the two highways on the northern slope of the strait. State Route 4 connects these highways south of and inland from the strait, a rail bridge just east of the Benicia-Martinez bridge is used by the Capitol Corridor, California Zephyr, and Coast Starlight trains. A rail ferry, with the ferries Contra Costa and Solano provided service across the strait near the location of the current rail bridge until the bridge was built in 1930. Tall pylons carrying power lines cross the strait as well, the Carquinez Strait Powerline Crossing was the worlds first powerline crossing of a large river. The channel is navigable and is used for commercial and military shipping, deep water ship traffic bound for both the Port of Sacramento and the Port of Stockton traverse the strait. The narrow gap in the Coast Range that forms the strait has led to the formation of the San Joaquin-Sacramento River Delta, a river delta, upstream of it. The strait is too small to allow the passage of huge amounts of floodwaters created during years with heavy rainfall/snowmelt events. Because the Delta area is the first to fill and last to drain in an event, silt and soil have more time to drop out of suspension

Pacific Ocean
–
The Pacific Ocean is the largest and deepest of the Earths oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean in the south and is bounded by Asia and Australia in the west, the Mariana Trench in the western North Pacific is the deepest point in the world, reaching a depth of 10,911 metres. Both the center of the Water Hemisphere and the Western Hemisphere are in the Pacific Ocean, the oceans current name was coined by Portuguese explorer Ferdinand Magellan during the Spanish circumnavigation of the world in 1521, as he encountered favourable winds on reaching the ocean. He called it Mar Pacífico, which in both Portuguese and Spanish means peaceful sea, important human migrations occurred in the Pacific in prehistoric times. Long-distance trade developed all along the coast from Mozambique to Japan, trade, and therefore knowledge, extended to the Indonesian islands but apparently not Australia. By at least 878 when there was a significant Islamic settlement in Canton much of trade was controlled by Arabs or Muslims. In 219 BC Xu Fu sailed out into the Pacific searching for the elixir of immortality, from 1404 to 1433 Zheng He led expeditions into the Indian Ocean. The east side of the ocean was discovered by Spanish explorer Vasco Núñez de Balboa in 1513 after his expedition crossed the Isthmus of Panama and he named it Mar del Sur because the ocean was to the south of the coast of the isthmus where he first observed the Pacific. Later, Portuguese explorer Ferdinand Magellan sailed the Pacific East to West on a Castilian expedition of world circumnavigation starting in 1519, Magellan called the ocean Pacífico because, after sailing through the stormy seas off Cape Horn, the expedition found calm waters. The ocean was often called the Sea of Magellan in his honor until the eighteenth century, sailing around and east of the Moluccas, between 1525 and 1527, Portuguese expeditions discovered the Caroline Islands, the Aru Islands, and Papua New Guinea. In 1542–43 the Portuguese also reached Japan, in 1564, five Spanish ships consisting of 379 explorers crossed the ocean from Mexico led by Miguel López de Legazpi and sailed to the Philippines and Mariana Islands. The Manila galleons operated for two and a half centuries linking Manila and Acapulco, in one of the longest trade routes in history, Spanish expeditions also discovered Tuvalu, the Marquesas, the Cook Islands, the Solomon Islands, and the Admiralty Islands in the South Pacific. In the 16th and 17th century Spain considered the Pacific Ocean a Mare clausum—a sea closed to other naval powers, as the only known entrance from the Atlantic the Strait of Magellan was at times patrolled by fleets sent to prevent entrance of non-Spanish ships. On the western end of the Pacific Ocean the Dutch threatened the Spanish Philippines, Spain also sent expeditions to the Pacific Northwest reaching Vancouver Island in southern Canada, and Alaska. The French explored and settled Polynesia, and the British made three voyages with James Cook to the South Pacific and Australia, Hawaii, and the North American Pacific Northwest, one of the earliest voyages of scientific exploration was organized by Spain in the Malaspina Expedition of 1789–1794. It sailed vast areas of the Pacific, from Cape Horn to Alaska, Guam and the Philippines, New Zealand, Australia, and the South Pacific. Growing imperialism during the 19th century resulted in the occupation of much of Oceania by other European powers, and later, Japan, in Oceania, France got a leading position as imperial power after making Tahiti and New Caledonia protectorates in 1842 and 1853 respectively. After navy visits to Easter Island in 1875 and 1887, Chilean navy officer Policarpo Toro managed to negotiate an incorporation of the island into Chile with native Rapanui in 1888, by occupying Easter Island, Chile joined the imperial nations

Central Valley (California)
–
Californias Central Valley is a large, flat valley that dominates the geographical center of the U. S. state of California. It is 40 to 60 miles wide and stretches approximately 450 miles from north-northwest to south-southeast, inland from and it covers approximately 18,000 square miles, about 11% of Californias total land area. More than 7 million acres of the valley are irrigated via a system of reservoirs. The valley also has many cities, including the state capital Sacramento, as well as Redding, Stockton, Modesto, Fresno. The Central Valley watershed comprises 60,000 square miles, or over a third of California, the delta empties into the San Francisco Bay, and then ultimately flows into the Pacific. The Central Valley is commonly known to simply as the Valley. Older names include the Great Valley, a name often seen in scientific references, and Golden Empire. The Central Valley is outlined by the Cascade, Sierra Nevada, and Tehachapi mountain ranges on the east, the broad valley floor is carpeted by vast agricultural regions, and dotted with numerous population centers. While there are many large and small between these cities, these four cities act as hubs for regional commerce and transportation. About 6.5 million people live in the Central Valley today, there are 12 Metropolitan Statistical Areas and 1 Micropolitan Statistical Area in the Central Valley. Below, they are listed by MSA and μSA population, the largest city is Fresno, followed by the state capital, Sacramento. The valley is thought to have originated below sea level as an offshore area depressed by subduction of the Farallon Plate into a trench further offshore, the San Joaquin Fault is a notable seismic feature of the Central Valley. The valley was later enclosed by the uplift of the Coast Ranges, faulting moved the Coast Ranges, and a new outlet developed near what is now San Francisco Bay. The one notable exception to the valley floor is Sutter Buttes. Another significant geologic feature of the Central Valley lies hidden beneath the delta, the Stockton Arch is an upwarping of the crust beneath the valley sediments which extends southwest to northeast across the valley. However, much of the Central Valley environment has been removed or altered by human activity including the introduction of exotic plants, the oak woodlands and chaparral that fringe the valley have been categorized as the California interior chaparral and woodlands ecoregion. The wetlands have been the target of operations to restore areas nearly destroyed by agriculture. The dominant grass of the valley was Nassella pulchra mixed with other species, grassland flowers include California poppy, lupins, and purple owls clover which can still be seen, especially in Antelope Valley in the Tehachapi hills

Sonoma Creek
–
Sonoma Creek is a 33. 4-mile-long stream in northern California. The watershed drained by Sonoma Creek is roughly equivalent to the region of Sonoma Valley. The State of California has designated the Sonoma Creek watershed as a “Critical Coastal Water Resource”, to the east of this generally rectangular watershed is the Napa River watershed, and to the west are the Petaluma River and Tolay Creek watersheds. As the tributaries and headwaters reach the floor, a perennial stream cuts through scenic. In the city of Sonoma it is a creek which emerges into agricultural areas to the south. Finally, Sonoma Creek discharges to the vast Napa-Sonoma Marsh at the tip of San Pablo Bay. Principal tributaries to the creek include Yulupa Creek, Graham Creek, Calabazas Creek, Bear Creek, Schell Creek, the headwaters cut through gorge and meadow of Sugarloaf Ridge State Park, which boasts 25 miles of self-guided trails and the Robert Ferguson Observatory. There is also a 25 foot high waterfall, present only when fed by the winter rains, the understory features abundant ferns and boulder laden mosses. A prominent landform in this upper reach created by Sonoma Creek is Adobe Canyon, locally part of this upper reach flow is sometimes called Adobe Creek. Tributaries near the headwaters include Mount Hood Creek and Graywood Creek, a diversity of aquatic and terrestrial organisms populate Sonoma Creek and its riparian zone. Winter-run Chinook salmon, Delta smelt and steelhead are the most prominent fishes, anadromous fish movements in Sonoma Creek have been studied extensively not only in the mainstem Sonoma Creek, but in some of the tributaries. A variety of salamanders, snakes and frogs are also present, the federally listed as threatened California red-legged frog is present in the northern reach draining the south slopes of Annadel State Park. The above are endangered species with the exception of the splittail, steelhead and black rail, California golden beaver were historically abundant along Sonoma Creek but were trapped out in the California Fur Rush of the late eighteenth and early nineteenth centuries. In 1828 fur trapper Michel La Framboise travelled from the Bonaventura River to San Francisco and then the missions of San José, San Francisco Solano and San Rafael Arcángel. La Framboise stated that the Bay of San Francisco abounds in beaver, the beaver were likely wiped out by the mid-nineteenth century but returned to Sonoma Creek, likely from the Delta, in the 1990s. In 1996 a beaver family developed a taste for merlot grapevine bark in a vineyard beside the creek and were exterminated, leading to civic uproar, new beavers have recolonized Sonoma Creek and are currently located in both Sonoma and Glen Ellen. Prominent higher elevation trees include, coast live oak, Garry oak, Pacific madrone, California buckeye, Douglas fir, up until about 1850 Sonoma Creek was unchanged from its natural state. Adverse erosion and bank cutting were at sustainable levels and did not add enough turbidity to the system to discourage aquatic species

Napa Sonoma Marsh
–
The Napa Sonoma Marsh is a wetland at the northern edge of San Pablo Bay, which is a northern arm of the San Francisco Bay in California, United States. This marsh has an area of 48,000 acres, of which 13,000 acres are abandoned salt evaporation ponds, the United States Government has designated 13,000 acres in the Napa Sonoma Marsh as the San Pablo Bay National Wildlife Refuge. The marsh is fed by Sonoma Creek, Tolay Creek, although the marsh extends north as far as State Route 12, as a practical matter, most of the marsh is only accessible by boat. Because of its rich avafaunal content, the Napa Sonoma Marsh is one of only seven marshes selected for study by the Point Reyes Bird Observatory. Around 1860, the Napa Sonoma Marsh was one of the most productive wetlands of the Pacific Coast, by the mid-1980s, the San Francisco Bay perimeter had lost over 91 percent of its wetlands. The Napa Sonoma Marsh represents one of the few sizeable expanses where restoration is feasible, an extensive research literature base exists for the Napa Sonoma Marsh.

San Rafael Creek
–
San Rafael Creek is a watercourse in Marin County, California, United States that discharges to San Rafael Bay, a small embayment of the San Francisco Bay. The mouth of San Rafael Creek is an estuary through an industrial area. In September 2007, the organization Save The Bay designated San Rafael Creek as one of the top ten worst trash hot spot waterways flowing into the San Francisco Bay. The channel portion of San Rafael Creek below the Grand Street Bridge is dredged on a maintenance schedule to keep the shallow draft channel navigable. Dredge spoils are disposed of at a site near Alcatraz Island, most of the soils in the lower watershed are clays and bay mud, resulting in a low transmissivity of groundwater. Typical vertical soil profiles in the watershed are four to five feet of imported fill over 60 to 65 feet of bay mud set on a basement of Franciscan Sandstone bedrock. At the mouth of San Rafael Creek, situated on the bank, is Pickleweed Park. List of watercourses in the San Francisco Bay Area Salt Marsh Harvest Mouse

Petaluma River
–
The Petaluma River is a river in the California counties of Sonoma and Marin that becomes a tidal slough for the majority of its length. The headwaters are in the area southwest of Cotati, the word Petaluma may derive from the Miwok words pe’ta, flat, and luma, back. The Miwok people lived in Sonoma County for more than 2500 years, Petaluma was the name of a village on a low hill east of Petaluma creek and north east of the present day town of Petaluma. The first recorded exploration of the Petaluma River was by Captain Fernando Quiros in October,1776, located in southern Sonoma County, California, and a portion of northeastern Marin, the Petaluma River Watershed drains 146 square miles. The watershed is approximately 19 miles long and 13 miles wide with the City of Petaluma near its center, the lower 12 miles of the Petaluma River flow through the Petaluma Marsh, the largest remaining salt marsh in San Pablo Bay. The marsh covers 5,000 acres and is surrounded by approximately 7,000 acres of reclaimed wetlands, in the marshes west of Lakeville, the river is joined by San Antonio Creek, at which point it becomes the boundary between Marin County and Sonoma County. The river flows under State Route 37 at Green Point and enters northwest San Pablo Bay just north of Petaluma Point, while the rivers source lies over 300 ft above sea level, it descends to 50 ft within about 0.4 mi. The river is fully tidal 11 mi from its mouth, indicating its slight gradient through the marshes below Petaluma, the United States Army Corps of Engineers dredges this section to keep it navigable by gravel barges and pleasure craft. The Petaluma River Watershed hosts several federally endangered animals including the salt marsh harvest mouse, endangered flora include soft bird’s-beak, Baker’s stickyseed, Burke’s goldfields, showy Indian clover, and Sebastopol meadowfoam. Steelhead that spawn and rear in the Petaluma River watershed are wild, not hatchery, Chinook salmon are seen in the main stem of the Petaluma River and The United Anglers of Casa Grande High School have seen chinook at the turning basin, near the Lynch Creek confluence. The high school constructed a salmonid hatchery in 1993 and in 200274 Chinook salmon returned to spawn in the Adobe Creek tributary. The marshes provide an important wildlife habitat and fish hatchery, however, since the onset of intensive immigration in the mid-1850s, the water quality has diminished, partly due to overgrazing and other agricultural uses. Pollutants present in the river include nitrates, phosphates, petroleum hydrocarbons, pesticides, urban runoff, particularly from the City of Petaluma, adds heavy metals and hydrocarbons to the river. Starting about 1990, material steps were taken to mitigate the pollution, because the Petaluma River is relatively well-protected, most of the pollution comes from nearby storm drains. It is up to the people of Petaluma to keep the river clean, because most of the length of the waterway is tidal and urban/suburban, there is a significant collection of tidally deposited debris along the banks. Despite the poor aesthetics including turbidity, the quality is not particularly poor. It has been alleged that the greatest threat to the Petaluma River is the planned Dutra asphalt plant, the reported concerns involve the loud noises it will create that will scare away the birds and throw off the entire ecosystem. The longest highway span, the 4-lane Route 37 bridge, is 2,183 ft long and was built in 1958, the oldest public bridge, built in 1925, is a 114 ft concrete triple span carrying two lanes of Petaluma Boulevard North

Napa River
–
The Napa River, approximately 55 miles long, is a river in the U. S. state of California. It drains a famous wine-growing region, called the Napa Valley, milliken Creek and Mt. Veeder watersheds are a few of its many tributaries. The mouth is at Vallejo where the inter-tidal zone of fresh, the Napa River rises in northwestern Napa County just south of the summit of Mt. St. Helena in the Mayacamas Mountains of the California Coast Ranges. The source begins as seasonal Kimball Canyon Creek in Robert Louis Stevenson State Park at an elevation of 3,745 feet which descends the slope of Mt. St. Helena to Kimball Canyon Dam. It flows south for 4 miles, entering the head of the slender Napa Valley north of Calistoga, in the valley, it flows southeast past Calistoga, St Helena, Rutherford, Oakville and through Napa, its head of navigation. Downstream from Napa, it forms an estuary, entering Mare Island Strait. It discharges into San Pablo Bay through the Napa Sonoma Marsh, the Napa River watershed encompasses approximately 426 square miles. Larger tributaries, such as Dry, Conn, and Soda creeks, several large dams were built between 1924 and 1959 on major eastside tributaries and the northern headwaters of the Napa River. In addition, many smaller dams can be throughout the watershed. These numerous dams are barriers to salmon and steelhead seeking their historic spawning grounds. The river also supports a diversity of fishes and recovering salmonid populations, especially chinook salmon. In 2003 the Napa County Resource Conservation District began an ongoing monitoring program. The Chinook run begins in late October through January, the Napa River basin is estimated to have historically supported a spawning run of 6, 000–8,000 steelhead, and as many as 2, 000–4,000 coho salmon. By the late 1960s, coho salmon were extirpated from the watershed, flow reductions in key rearing streams have reduced food availability for juvenile steelhead, causing reduced growth and survival. Recently, a salmon was caught in the river. In addition, a fourth species, sockeye salmon, was also identified in the Napa River. Because of this diversity the Napa River has been prioritized for special protection, white sturgeon and many other native and non-native fishes currently utilize the Napa River watershed. The California golden beaver was historically extant, recently beaver have recolonized the Napa River and have been documented in Napa as well as near Rutherford and Oak Knoll

United States Army Corps of Engineers
–
The United States Army Corps of Engineers, also sometimes shortened to CoE is a U. S. Although generally associated with dams, canals and flood protection in the United States, the Corps of Engineers provides outdoor recreation opportunities to the public, and provides 24% of U. S. hydropower capacity. The corps mission is to Deliver vital public and military engineering services, partnering in peace and war to strengthen our Nations security, energize the economy and their most visible missions include, Planning, designing, building, and operating locks and dams. Other civil engineering projects include flood control, beach nourishment, design and construction of flood protection systems through various federal mandates. Design and construction management of military facilities for the Army, Air Force, Army Reserve and Air Force Reserve and other Defense and Federal agencies. The history of United States Army Corps of Engineers can be traced back to 16 June 1775, colonel Richard Gridley became General George Washingtons first chief engineer, however, it was not until 1779 that Congress created a separate Corps of Engineers. One of its first tasks was to build fortifications near Boston at Bunker Hill, the first Corps of Engineers was mostly composed of French subjects who had been hired by General Washington from the service of Louis XVI. that the said Corps. Shall be stationed at West Point in the State of New York, until 1866, the superintendent of the United States Military Academy was always an officer of engineer. During the first half of the 19th century, West Point was the major and, for a while, the General Survey Act of 1824 authorized the use of Army engineers to survey road and canal routes. Separately authorized on 4 July 1838, the U. S and it was merged with the Corps of Engineers on 31 March 1863, at which point the Corps of Engineers also assumed the Lakes Survey District mission for the Great Lakes. In 1841, Congress created the Lake Survey, the survey, based in Detroit, Mich. was charged with conducting a hydrographical survey of the Northern and Northwestern Lakes and preparing and publishing nautical charts and other navigation aids. The Lake Survey published its first charts in 1852, in the mid-19th century, Corps of Engineers officers ran Lighthouse Districts in tandem with U. S. Naval officers. The Army Corps of Engineers played a significant role in the American Civil War, many of the men who would serve in the top leadership in this institution were West Point graduates who rose to military fame and power during the Civil War. Some of these men were Union Generals George McClellan, Henry Halleck, George Meade, and Confederate generals Robert E. Lee, Joseph Johnston, the versatility of officers in the Army Corps of Engineers contributed to the success of numerous missions throughout the Civil War. They were responsible for building pontoon and railroad bridges, forts and batteries, the destruction of supply lines. The Army Corps of Engineers served as a function in making the war effort logistically feasible. This method of building trenches was known as the zigzag pattern, from the beginning, many politicians wanted the Corps of Engineers to contribute to both military construction and works of a civil nature. During World War II the mission grew to more than 27,000 military, included were aircraft, tank assembly, and ammunition plants, camps for 5.3 million soldiers, depots, ports, and hospitals, as well as the Manhattan Project, and the Pentagon

Peninsula
–
A peninsula is a piece of land surrounded by water on the majority of its border, while being connected to a mainland from which it extends out. Examples include the upper and lower peninsulas of the state of Michigan, the surrounding water is usually understood to be continuous, though not necessarily named as a single body of water. Peninsulas are not always named as such, one can also be a headland, cape, island promontory, bill, point, a point is generally considered a tapering piece of land projecting into a body of water that is less prominent than a cape. A river which courses through a very tight meander is also said to form a peninsula within the loop of water. In English, the plural of peninsula is peninsulas or, less commonly, peninsulas can be found on coastlines and in smaller bodies of water throughout the world, ranging in scale from square meters to millions of square kilometers. Theres the Scandinavian Peninsula in Northern Europe, and in Southern Europe theres the Iberian Peninsula, the Italian Peninsula, south America has the Brunswick Peninsula, and Antarctica has the Antarctic Peninsula. In Africa, theres the Horn of Africa, and in Australia, asia has the 3 largest peninsulas in the world, the Arabian Peninsula, the Indian Peninsula, and the Indochinese Peninsula

Richmond, California
–
Richmond is a city in western Contra Costa County, California, United States. The city was incorporated on August 7,1905, under the McLaughlin Administration, Richmond was the largest city in the United States served by a Green Party mayor. As of the 2010 U. S. Census, the population is at 103,710. The largest, Richmond, Virginia, is the namesake of the California city, the Ohlone Indians were the first inhabitants of the Richmond area, settling an estimated 5,000 years ago.

Contra Costa County, California
–
Contra Costa County is a county in the state of California in the United States. As of the 2010 census, the population was 1,049,025, the name is Spanish for opposite coast, referring to its position on the other side of the bay from San Francisco. Contra Costa County is included in the San Francisco–Oakland–Hayward, CA Metropolitan Statistical Area and it occupies the northern portion of the East Bay region and is primarily suburban. In the northern part of the county, significant coal and sand deposits were formed in even earlier geologic eras, other areas of the county have ridges exposing ancient but intact seashells, embedded in sandstone layers alternating with limestone. Layers of volcanic ash ejected from geologically recent but now extinct volcanoes, compacted and now tilted by compressive forces, may be seen at the site of some road excavations. This county is an agglomeration of several distinct geologic terranes, as is most of the greater San Francisco Bay Area, younger deposits at middle altitudes include pillow lavas, the product of undersea volcanic eruptions. There is an extensive but little recorded human history pre-European settlement in this area, the earliest definitively established occupation by modern man appears to have occurred six to ten thousand years ago. However, there may have been human presence far earlier, at least as far as non–settling populations are concerned, extensive trading from tribe to tribe transferred exotic materials such as obsidian throughout the region from far distant Californian tribes. Unlike the nomadic Native American of the Great Plains it appears that these tribes did not incorporate warfare into their culture but were generally cooperative. Within these cultures the concept of individual or collective land ownership was nonexistent, early European settlers in the region, however, did not record much about the culture of the natives. Most of what is known comes from preserved contemporaneous and excavated artifacts. Although there were no missions established within this county, Spanish influence here was direct and extensive, in 1821 Mexico gained independence from Spain. Mission lands extended throughout the Bay Area, including portions of Contra Costa County, between 1836 and 1846, during the era when California was a province of independent Mexico, the following 15 land grants were made in Contra Costa County. Rough surveying was based on a map, or diseño, measured by streams, shorelines, and/or horseman who marked it with rope, lands outside rancho grants were designated el sobrante, as in surplus or excess, and considered common lands. The law required the construction of a house within a year, fences were not required and were forbidden where they might interfere with roads or trails. Locally a large family required roughly 2000 head of cattle and two leagues of land to live comfortably. Foreign entrepreneurs came to the area to provide goods that Mexico couldn’t, Rancho Canada de los Vaqueros was granted to Francisco Alviso, Antonio Higuera, and Manuel Miranda. Two ranchos, both called Rancho San Ramon, were granted by the Mexican government in the San Ramon Valley, in 1833, Bartolome Pacheco and Mariano Castro shared the two square league Rancho San Ramon

Salt marsh
–
It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the marsh in trapping and binding sediments. Salt marshes play a role in the aquatic food web. They also support terrestrial animals and provide coastal protection, salt marshes occur on low-energy shorelines in temperate and high-latitudes which can be stable or emerging, or submerging if the sedimentation rate exceeds the subsidence rate. Commonly these shorelines consist of mud or sand flats which are nourished with sediment from inflowing rivers and these typically include sheltered environments such as embankments, estuaries and the leeward side of barrier islands and spits. In the tropics and sub-tropics they are replaced by mangroves, an area that differs from a marsh in that instead of herbaceous plants. Most salt marshes have a low topography with low elevations but a vast wide area, salt marshes are located among different landforms based on their physical and geomorphological settings. Such marsh landforms include deltaic marshes, estuarine, back-barrier, open coast, embayments, deltaic marshes are associated with large rivers where many occur in Southern Europe such as the Camargue, France in the Rhone delta or the Ebro delta in Spain. They are also extensive within the rivers of the Mississippi Delta in the United States, in New Zealand, most salt marshes occur at the head of estuaries in areas where there is little wave action and high sedimentation. Such marshes are located in Awhitu Regional Park in Auckland, the Manawatu Estuary, back-barrier marshes are sensitive to the reshaping of barriers in the landward side of which they have been formed. They are common along much of the eastern coast of the United States, large, shallow coastal embayments can hold salt marshes with examples including Morecambe Bay and Portsmouth in Britain and the Bay of Fundy in North America. They have a big impact on the biodiversity of the area, salt marsh ecology involves complex food webs which include primary producers, primary consumers, and secondary consumers. The low physical energy and high grasses provide a refuge for animals, many marine fish use salt marshes as nursery grounds for their young before they move to open waters. Saltmarshes across 99 countries were mapped by Mcowen et al, a total of 5,495,089 hectares of mapped saltmarsh across 43 countries and territories are represented in a Geographic Information Systems polygon shapefile. This estimate is at the low end of previous estimates. Mats of filamentous blue-green algae can fix silt and clay sized sediment particles to their sticky sheaths on contact which can increase the erosion resistance of the sediments. This assists the process of sediment accretion to allow colonising species to grow, as a result, competitive species that prefer higher elevations relative to sea level can inhabit the area and often a succession of plant communities develops. Coastal salt marshes can be distinguished from terrestrial habitats by the tidal flow that occurs

Mudflat
–
Mudflats or mud flats, also known as tidal flats, are coastal wetlands that form when mud is deposited by tides or rivers. They are found in sheltered areas such as bays, bayous, lagoons, mudflats may be viewed geologically as exposed layers of bay mud, resulting from deposition of estuarine silts, clays and marine animal detritus. Most of the sediment within a mudflat is within the intertidal zone, in the past tidal flats were considered unhealthy, economically unimportant areas and were often dredged and developed into agricultural land. Several especially shallow mudflat areas, such as the Wadden Sea, are now popular among those practising the sport of mudflat hiking. On the Baltic Sea coast of Germany in places, mudflats are exposed not by tidal action and these wind-affected mudflats are called windwatts in German. Tidal flats, along with salt marshes and mangrove forests, are important ecosystems. They are often of importance to migratory birds, as well as certain species of crabs, mollusks. In the United Kingdom mudflats have been classified as a Biodiversity Action Plan priority habitat, the maintenance of mudflats is important in preventing coastal erosion. However, mudflats worldwide are under threat from predicted sea level rises, land claims for development, dredging due to shipping purposes, in some parts of the world, such as East and South-East Asia, mudflats have been reclaimed for aquaculture, agriculture, and industrial development. For example, around the Yellow Sea region of East Asia, mudflat sediment deposits are focused into the intertidal zone which is composed of a barren zone, marsh and salt pan. Within these areas are various ratios of sand and mud that make up the sedimentary layers, the associated growth of coastal sediment deposits can be attributed to rates of subsidence along with rates of deposition and changes in sea level. Barren zones extend from the lowest portion of the zone to the marsh areas. Beginning in close proximity to the bars, sand dominated layers are prominent. Common bedding types include laminated sand, ripple bedding, and bay mud, bioturbation also has a strong presence in barren zones. Marshes contain an abundance of plants while the sediment layers consist of thin sand. Mudcracks are a common as well as wavy bedding planes, marshes are also the origins of coal/peat layers because of the abundant decaying plant life. Salt pans can be distinguished in that they contain thinly laminated layers of clayey silt, the main source of the silt comes from rivers. Dried up mud along with wind erosion forms silt dunes, when flooding, rain or tides come in, the dried sediment is then re-distributed

Canvasback
–
The canvasback is a species of diving duck, the largest found in North America. It ranges from 48–56 cm in length and weighs 862–1,600 g and it is the largest species in the Aythya genus, being similar in size to a mallard but with a heavier and more compact build than it. 191 males wintering in western New York averaged 1,252 g and 54 females there averaged 1,154 g, the canvasback has a distinctive wedge-shaped head and long graceful neck. The adult male has a bill, a chestnut red head and neck, a black breast, a grayish back, black rump. The drakes sides, back, and belly are white with fine vermiculation resembling the weave of a canvas, the bill is blackish and the legs and feet are bluish-gray. The iris is red in the spring, but duller in the winter. The adult female also has a bill, a light brown head and neck, grading into a darker brown chest. The sides, flanks, and back are grayish brown, the bill is blackish and the legs and feet are bluish-gray. Its sloping profile distinguishes it from other ducks, the genus name is derived from Greek aithuia, an unidentified seabird mentioned by authors, including Hesychius and Aristotle. The species name comes from the wild celery Vallisneria americana, whose winter buds. The celery genus is named for seventeenth century Italian botanist Antonio Vallisneri. The ducks common name is based on early European inhabitants of North Americas assertion that its back was a canvas-like color, in other languages it is just a white-backed duck, for example in French, morillon à dos blanc, or Spanish, pato lomo blanco. In Mexico it is called pato coacoxtle, the breeding habitat of the canvasback is in North America prairie potholes. The bulky nest is built from vegetation in a marsh and lined with down, loss of nesting habitat has caused populations to decline. The canvasback usually takes a new mate each year, pairing in late winter on ocean bays and it prefers to nest over water on permanent prairie marshes surrounded by emergent vegetation, such as cattails and bulrushes, which provide protective cover. Other important breeding areas are the river deltas in Saskatchewan. It has a size of approximately 5–11 eggs, which are greenish drab. The chicks are covered in down at hatching and able to leave the nest soon after, the canvasback sometimes lays its eggs in other canvasback nests and redheads often parasitize canvasback nests

Pacific Flyway
–
The Pacific Flyway is a major north-south flyway for migratory birds in America, extending from Alaska to Patagonia. Every year, migratory birds travel some or all of this both in spring and in fall, following food sources, heading to breeding grounds, or travelling to overwintering sites. Any given bird species travels roughly the route every year. Ornithologists and bird lovers can often predict to the day when a species will show up in their area. Along the Pacific Flyway, there are many key rest stops where birds of many species gather, sometimes in the millions, to feed, some species may remain in these rest stops for the entire season, but most stay a few days before moving on. Notable locations include, Boundary Bay, British Columbia, has listed as an Important Bird Area by the Canadian government in recognition of its value to migratory birds. Klamath Basin National Wildlife Refuges Complex consists of different wildlife refuges on the border of Oregon. The Summer Lake Wildlife Sanctuary, located on Hwy 31, across from the Summer Lake Lodge, sacramento National Wildlife Refuge Complex consists of several wildlife refuges in the northern Central Valley of California. San Luis National Wildlife Refuge Complex consists of wildlife refuges in the San Joaquin Valley of California. Suisun Marsh, next to the exit of the inverted Sacramento-San Joaquin River Delta, has protected portions, San Francisco Bay, protected estuaries and mountain open space preserves. Coyote Valley, a section of the Santa Clara Valley with one of the highest recorded bird species richness. Great Salt Lake, Utah, a Great Basin hub of flyway, monterey Bay, protected estuaries and mountain open space preserves. Ballona Wetlands between the Los Angeles neighborhoods of Playa del Rey and Marina del Rey and adjacent city-owned lagoons, salton Sea, an inland Colorado Desert saline endorheic lake in Southern California, hosts many birds and has surrounding wildlife refuges.

San Pablo Bay National Wildlife Refuge
–
San Pablo Bay National Wildlife Refuge is a 13, 190-acre National Wildlife Refuge in California established in 1970. It extends along the shore of San Pablo Bay, from the mouth of the Petaluma River, to Tolay Creek, Sonoma Creek. The refuge encompasses the largest remaining patch of pickleweed-dominated tidal marsh in the northern San Francisco Bay. Historically, the wetlands surrounding San Pablo Bay were one of the largest tidal marsh complexes on the Pacific Coast of North America. However, the area has significantly impacted by human activities such as hydraulic mining, salt production, diking, draining, filling, agriculture. All told, about 85% of San Pablo Bays tidal marshes have been altered, the Refuge includes a variety of habitats including open water, mud flat, tidal marsh, estuary, and seasonal and managed wetlands. The refuge hosts millions of shorebirds and waterfowl, including the largest wintering population of canvasbacks on the west coast. The Refuge also provides habitat for sensitive species including the endangered California clapper rail. Public access to the refuge is provided by the Tolay Creek Tubbs Island Trail and this article incorporates public domain material from websites or documents of the United States Fish and Wildlife Service. Provides a brief history of the marshes of San Pablo Bay

Endangered species
–
An endangered species is a species which has been categorized as likely to become extinct. In 2012, the IUCN Red List featured 3079 animal and 2655 plant species as endangered worldwide, the figures for 1998 were, respectively,1102 and 1197. Many nations have laws that protect conservation-reliant species, for example, population numbers, trends and species conservation status can be found in the lists of organisms by population. The conservation status of a species indicates the likelihood that it will become extinct, the IUCN Red List of Threatened Species is the best-known worldwide conservation status listing and ranking system. Over 40% of the species are estimated to be at risk of extinction. Internationally,199 countries have signed an accord to create Biodiversity Action Plans that will protect endangered, in the United States, such plans are usually called Species Recovery Plans. Those species of Near Threatened and Least Concern status have been assessed and found to have relatively robust and healthy populations, though these may be in decline. The IUCN categories, with examples of animals classified by them, include, Extinct Extinct in the wild Captive individuals survive, critically endangered Faces an extremely high risk of extinction in the immediate future. Endangered Faces a high risk of extinction in the near future, vulnerable Faces a high risk of endangerment in the medium term. Near-threatened May be considered threatened in the near future, Least concern No immediate threat to species survival. A population size reduction of ≥ 50%, projected or suspected to be met within the next 10 years or three generations, whichever is the longer, based on any of to under A1. E) Quantitative analysis showing the probability of extinction in the wild is at least 20% within 20 years or five generations, there is data from the United States that shows a correlation between human populations and threatened and endangered species. Under the Endangered Species Act in the United States, species may be listed as endangered or threatened, the Salt Creek tiger beetle is an example of an endangered subspecies protected under the ESA. Some endangered species laws are controversial, also lobbying from hunters and various industries like the petroleum industry, construction industry, and logging, has been an obstacle in establishing endangered species laws. The Bush administration lifted a policy that required federal officials to consult an expert before taking actions that could damage endangered species. Under the Obama administration, this policy has been reinstated, being listed as an endangered species can have negative effect since it could make a species more desirable for collectors and poachers. This effect is potentially reducible, such as in China where commercially farmed turtles may be reducing some of the pressure to poach endangered species. Another problem with the species is its effect of inciting the use of the shoot, shovel

Brown pelican
–
The brown pelican is a small pelican found in the Americas. It is one of the best known and most prominent birds found in the areas of the southern and western United States. It is one of only three species found in the Western Hemisphere and one of the only two that feeds by diving into the water. The brown pelican is the smallest of the eight species of pelican and it is 106–137 cm in length, weighs from 2.75 to 5.5 kg and has a wingspan from 1.83 to 2.5 m. Through most of its range, the pelican is an unmistakable bird. Like all pelicans, this species has a large bill,28 to 34.8 cm long in this case. The head is white but often gets a yellowish wash in adult birds, the bill is grayish overall in most birds, though breeding birds become reddish on the underside of the throat. The back, rump, and tail are streaked with gray and dark brown, in adult pelicans, the breast and belly are a blackish-brown and the legs and feet are black. The juvenile is similar but has a neck and white underparts. The Peruvian pelican, previously considered a subspecies of brown pelican, is now considered to be a separate species and it has very similar plumage to the brown, but it is noticeably larger. The brown and Peruvian pelicans may overlap in areas along the Pacific coast of South America. The brown pelican lives on both coasts in the Americas, on the Atlantic Coast and Gulf Coast they distribute from Nova Scotia to Venezuela, and to the mouth of the Amazon River. Along the Atlantic, they are less common north of the Carolinas. On the Pacific Ocean they are found from British Columbia to northern Peru, in the Pacific, they are fairly common along the coast of California, Mexico and Central America. Some immature birds may stray to inland freshwater lakes, after nesting, North American birds move in flocks further north along the coasts, returning to warmer waters for winter. They are also common in Mangrove swamps, Pelicans are very gregarious birds, they live in flocks of both sexes throughout the year. They are exceptionally buoyant due to the air sacks beneath their skin and in their bones. In level flight, pelicans fly in groups, with their heads back on their shoulders

Ridgway's rail
–
Ridgways rail is a near-threatened species of bird. It is found principally in Californias San Francisco Bay to southern Baja California, a member of the rail family, Rallidae, it is a chicken-sized bird that rarely flies. This species is related to the clapper rail, and until recently was considered a subspecies. It has a long, downward curving bill and is brown with a pale chestnut breast. The population levels of Ridgways rail are precariously low due to destruction of its coastal and estuarine marshland habitat by prior land development and it has year-long, circadian activity and is most vocal nocturnally and crepuscularly. Ridgways rail forages at the end of, along the ecotone between mudflat and higher vegetated zones, and in tidal sloughs. Mussels, clams, arthropods, snails, worms and small fish are its preferred foods, the bird will only forage on mudflats or very shallow water where there is taller plant material nearby to provide protection at high tide. At such high tides it may also prey upon mice, and has known to scavenge dead fish. One of the largest population of Ridgways rails is in San Francisco Bay, for cover, Ridgways rail seeks out emergent wetland dominated by pickleweed and cordgrass, or brackish emergent wetland with those two plants plus bulrush. It is not clear whether it requires any source of fresh water, although not migratory in coastal wetlands, this species disperses juveniles into freshwater wetlands in late August through October. Ridgways rail breeds in the San Francisco Bay from mid-March through August, during this breeding season the bird density was approximately 0.1 to 0.6 individuals per acre, outside of breeding season densities decline to 0.04 to 0.40 individuals per acre. The twig nest is placed low sometimes among plant roots, eggs are produced in clutches of four to fourteen, with an average yield of 7.6. The incubation period is 18 to 29 days, and the success is 38%.

Salt marsh harvest mouse
–
There are two distinct subspecies, both endangered and listed together on federal and state endangered species lists. The northern subspecies is lighter in color and inhabits the marshes of the bay. They are both similar in appearance to their congener species, the, to which they are not closely related. Genetic studies of the subspecies have revealed that the salt marsh harvest mouse is most closely related to the plains harvest mouse, R. montanus. Its endangered designation is due to its range, historic decline in population. The southern population of the salt marsh harvest mouse tends to have brown fur above and a pinkish cinnamon or tawny belly, moreover. An adults length is five to seven centimeters and a length of six to ten centimeters. The height is between 1.5 and 2.1 centimeters, weight of a mature mouse is approximately 10 to 20 grams. The northern subspecies is also dorsally brown or reddish brown, but the venters tend to be white or cream and this species is nocturnal, with particularly noted activity on moonlit nights. This mouse is particularly resourceful, making use of runways of other rodents, moreover. It occupies marsh habitats where pickleweed and marsh plants abound and its many predators feature hawk, snake and owl species, as well as shorebirds and larger mammals. Predation by domestic cats is a due to encroachment of the limited habitat by humans at the perimeter of the San Francisco Bay. As would be expected of a native to salt marshes. It eats seeds and plants, especially pickleweed and glasswort, one of the most common salt marsh plant species, similar species are the Plains Harvest Mouse, and the Fulvous Harvest Mouse, which has a longer tail. Survey data from Suisun Marsh found that the salt marsh harvest mouse can live up to 18 months, females commonly have two litters per year. In the summer, when salinity of water and vegetation increases, the northern species can survive purely on salt water, but prefers fresh water to salt water. The southern species can survive on either, and does not display a preference, the mice depend heavily on vegetation cover, particularly pickleweed and tules. Pickleweed is their primary and preferred habitat as well their main food source and they can also survive tidal or seasonal flooding due to their superior ability to swim, float and climb

Fishing
–
Fishing is the activity of trying to catch fish. Fish are normally caught in the wild, techniques for catching fish include hand gathering, spearing, netting, angling and trapping. Fishing may include catching aquatic animals other than fish, such as molluscs, cephalopods, crustaceans, the term is not normally applied to catching farmed fish, or to aquatic mammals, such as whales where the term whaling is more appropriate. According to United Nations FAO statistics, the number of commercial fishermen. Fisheries and aquaculture provide direct and indirect employment to over 500 million people in developing countries, in 2005, the worldwide per capita consumption of fish captured from wild fisheries was 14.4 kilograms, with an additional 7.4 kilograms harvested from fish farms. In addition to providing food, modern fishing is also a recreational pastime, Fishing is an ancient practice that dates back to at least the beginning of the Upper Paleolithic period about 40,000 years ago. Isotopic analysis of the remains of Tianyuan man, a 40. Archaeology features such as middens, discarded fish bones, and cave paintings show that sea foods were important for survival. During this period, most people lived a lifestyle and were, of necessity. However, where there are examples of permanent settlements such as those at Lepenski Vir. The British dogger was a type of sailing trawler from the 17th century. The Brixham trawler that evolved there was of a build and had a tall gaff rig. They were also sufficiently robust to be able to tow large trawls in deep water, the great trawling fleet that built up at Brixham, earned the village the title of Mother of Deep-Sea Fisheries. The small village of Grimsby grew to become the largest fishing port in the world by the mid 19th century, an Act of Parliament was first obtained in 1796, which authorised the construction of new quays and dredging of the Haven to make it deeper. It was only in the 1846, with the expansion in the fishing industry. The foundation stone for the Royal Dock was laid by Albert the Prince consort in 1849, the dock covered 25 acres and was formally opened by Queen Victoria in 1854 as the first modern fishing port. The elegant Brixham trawler spread across the world, influencing fishing fleets everywhere, by the end of the 19th century, there were over 3,000 fishing trawlers in commission in Britain, with almost 1,000 at Grimsby. These trawlers were sold to fishermen around Europe, including from the Netherlands, twelve trawlers went on to form the nucleus of the German fishing fleet

Seawater
–
Seawater, or salt water, is water from a sea or ocean. On average, seawater in the oceans has a salinity of about 3. 5% This means that every kilogram of seawater has approximately 35 grams of dissolved salts. Average density at the surface is 1.025 kg/l, seawater is denser than both fresh water and pure water because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases, at typical salinity, it freezes at about −2 °C. The coldest seawater ever recorded was in 2010, in a stream under an Antarctic glacier, seawater pH is typically limited to a range between 7.5 and 8.4. However, there is no universally accepted reference pH-scale for seawater, although the vast majority of seawater has a salinity of between 31 g/kg and 38 g/kg, seawater is not uniformly saline throughout the world. Where mixing occurs with fresh water runoff from river mouths, near melting glaciers or vast amounts precipitation, the most saline open sea is the Red Sea, where high rates of evaporation, low precipitation and low river run-off, and confined circulation result in unusually salty water. The salinity in isolated bodies of water can be considerably greater still, historically, several salinity scales were used to approximate the absolute salinity of seawater. A popular scale was the Practical Salinity Scale where salinity was measured in practical salinity units, the current standard for salinity is the Reference Salinity scale with the salinity expressed in units of g/kg. The density of surface seawater ranges from about 1020 to 1029 kg/m3, depending on the temperature, at a temperature of 25 °C, salinity of 35 g/kg and 1 atm pressure, the density of seawater is 1023.6 kg/m3. Deep in the ocean, under pressure, seawater can reach a density of 1050 kg/m3 or higher. The density of seawater also changes with salinity, brines generated by seawater desalination plants can have salinities up to 120 g/kg. The density of typical seawater brine of 120 g/kg salinity at 25 °C, seawater pH is limited to the range 7.5 to 8.4. The speed of sound in seawater is about 1,500 m/s, and varies with temperature, salinity. The thermal conductivity of seawater is 0.6 W/mK at 25 °C, the thermal conductivity decreases with increasing salinity and increases with increasing temperature. Seawater contains more dissolved ions than all types of freshwater, however, the ratios of solutes differ dramatically. Bicarbonate ions also constitute 48% of river water solutes but only 0. 14% of all seawater ions, differences like these are due to the varying residence times of seawater solutes, sodium and chlorine have very long residence times, while calcium tends to precipitate much more quickly. The most abundant dissolved ions in seawater are sodium, chloride, magnesium, sulfate and its osmolarity is about 1000 mOsm/l
