Nevada State Route 147
State Route 147 is a state highway serving the Las Vegas Valley in southern Nevada. It is signed as Lake Mead Boulevard and runs from Interstate 15 in North Las Vegas east to the border of the Lake Mead National Recreation Area, it is not to be confused with Lake Mead Parkway, which goes to Lake Mead but runs in southern Las Vegas Valley and carries the designation of State Route 564. Lake Mead Boulevard became a state highway in 1978, but the highway never had markers posted to identify it as a state highway. State Route 147 begins at Interstate 15 and U. S. Route 93 in North Las Vegas. From there, SR 147 has an intersection at Civic Center Drive. Traveling further east, SR 147 leaves the city of North Las Vegas as it enters the unincorporated town of Sunrise Manor where it has intersections at Lamb Boulevard and Nellis Boulevard; the highway leaves the unincorporated town of Sunrise Manor as it travels through the Frenchman Mountain on its northern slope. The road curves into a southeastern direction where the highway ends near the Lake Mead NRA as Lake Mead Boulevard continues beyond the highway's eastern terminus.
SR 147 first appears on the official Nevada state highway map with the 1978-79 edition as a semi-circular route. The route followed Lake Mead Boulevard eastward from North Las Vegas to North Shore Road in the Lake Mead National Recreation Area; the terminus was at Boulder Highway. The highway continued west of Boulder Highway as SR 146; the northern section along Lake Mead Boulevard lacks the SR 147 designator on the 1983–84 and 1985-86 maps. However, it is back on the 1987-88 map, so it is unclear whether this was a map error or a planned decommissioning that wasn’t carried out. On the 1998-99 map, the southern section of SR 147 was replaced by an eastward extension of SR 146; the entire length of SR 147 is now on Lake Mead Boulevard, with the eastern terminus truncated to the northern border of the Lake Mead National Recreation Area. The entire route is in Clark County. RTC Transit Route 210 functions on this road. Nevada portal U. S. Roads portal Official Highway Map of Nevada. Nevada Department of Highways.

Lake Mead National Recreation Area
Lake Mead National Recreation Area is a U. S. National Recreation Area located in southeastern northwestern Arizona. Operated by the National Park Service, Lake Mead NRA follows the Colorado River corridor from the westernmost boundary of Grand Canyon National Park to just north of the cities of Laughlin and Bullhead City, Arizona, it includes all of the eponymous Lake Mead as well as the smaller Lake Mohave – reservoirs on the river created by Hoover Dam and Davis Dam – and the surrounding desert terrain and wilderness. Formation of Lake Mead began than a year before Hoover Dam was completed; the area surrounding Lake Mead was established as the Boulder Dam Recreation Area in 1936. In 1964, the area was expanded to include Lake Mohave and its surrounding area and became the first National Recreation Area to be designated as such by the U. S. Congress. Lake Mead NRA features water recreation, including boating and fishing, on both lakes as well as the stretches of river between the lakes, it features hiking trails and views of the surrounding desert landscape.
Three of the four desert ecosystems found in the United States — the Mojave Desert, the Great Basin Desert, the Sonoran Desert — meet in Lake Mead NRA. Tours of Hoover Dam – administered by the U. S. Bureau of Reclamation – are a major attraction within the recreation area. About 200,000 acres of the recreation area are managed separately under the Grand Canyon-Parashant National Monument, established in 2000. Water covers about 186,000 acres of the recreation area. There are nine designated wilderness areas under the National Wilderness Preservation System lying within Lake Mead National Recreation Area. All are in the Nevada portion. Parts of some of these wildernesses lie outside Lake Mead NRA and are managed by the Bureau of Land Management: Black Canyon Wilderness Bridge Canyon Wilderness Eldorado Wilderness Ireteba Peaks Wilderness Jimbilnan Wilderness Muddy Mountains Wilderness Nellis Wash Wilderness Pinto Valley Wilderness Spirit Mountain Wilderness 900 plant species 500 animal species 24 rare and threatened species 9 designated wilderness areas 122,166 museum objects and archives 1,347 recorded archeological sites 23 historic structures 8 listed National Register Properties 2 Traditional Cultural Properties Lakes Mead and Mohave offer some of the country’s best sport fishing.
The following species are found in both lakes: Largemouth Bass Striped Bass Crappie Rainbow Trout Catfish Bluegill For 2012, with 6.3 million recreational visits, Lake Mead National Recreation Area was the 5th most visited national park.

Nevada is a state in the Western United States. It is bordered by Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast and Utah to the east. Nevada is the 7th most extensive, the 32nd most populous, but the 9th least densely populated of the U. S. states. Nearly three-quarters of Nevada's people live in Clark County, which contains the Las Vegas–Paradise metropolitan area where three of the state's four largest incorporated cities are located. Nevada's capital, however, is Carson City. Nevada is known as the "Silver State" because of the importance of silver to its history and economy, it is known as the "Battle Born State", because it achieved statehood during the Civil War. Nevada is desert and semi-arid, much of it within the Great Basin. Areas south of the Great Basin are within the Mojave Desert, while Lake Tahoe and the Sierra Nevada lie on the western edge. About 86% of the state's land is managed by various jurisdictions of the U. S. federal government, both civilian and military.
Before European contact, Native Americans of the Paiute and Washoe tribes inhabited the land, now Nevada. The first Europeans to explore the region were Spanish, they called the region Nevada because of the snow. The area formed part of the Viceroyalty of New Spain, became part of Mexico when it gained independence in 1821; the United States annexed the area in 1848 after its victory in the Mexican–American War, it was incorporated as part of Utah Territory in 1850. The discovery of silver at the Comstock Lode in 1859 led to a population boom that became an impetus to the creation of Nevada Territory out of western Utah Territory in 1861. Nevada became the 36th state on October 31, 1864, as the second of two states added to the Union during the Civil War. Nevada has a reputation for its libertarian laws. In 1940, with a population of just over 110,000 people, Nevada was by far the least-populated state, with less than half the population of the next least-populated state. However, legalized gambling and lenient marriage and divorce laws transformed Nevada into a major tourist destination in the 20th century.
Nevada is the only U. S. state where prostitution is legal, though it is illegal in Clark County, Washoe County and Carson City. The tourism industry remains Nevada's largest employer, with mining continuing as a substantial sector of the economy: Nevada is the fourth-largest producer of gold in the world; the name "Nevada" comes from meaning "snow-covered", after the Sierra Nevada. Most Nevadans pronounce the second syllable of their state name using the TRAP vowel. Many from outside the Western United States pronounce it with the PALM vowel. Although the latter pronunciation is closer to the Spanish pronunciation, it is not the pronunciation preferred by most Nevadans. State Assemblyman Harry Mortenson proposed a bill to recognize the alternate pronunciation of Nevada, though the bill was not supported by most legislators and never received a vote; the Nevadan pronunciation is the de facto official one, since it is the one used by the state legislature. At one time, the state's official tourism organization, TravelNevada, stylized the name of the state as "Nevăda", with a breve mark over the a indicating the locally preferred pronunciation, available as a license plate design.
Nevada is entirely within the Basin and Range Province, is broken up by many north-south mountain ranges. Most of these ranges have endorheic valleys between them, which belies the image portrayed by the term Great Basin. Much of the northern part of the state is within the Great Basin, a mild desert that experiences hot temperatures in the summer and cold temperatures in the winter. Moisture from the Arizona Monsoon will cause summer thunderstorms; the state's highest recorded temperature was 125 °F in Laughlin on June 29, 1994. The coldest recorded temperature was −52 °F set in San Jacinto in 1972, in the northeastern portion of the state; the Humboldt River crosses the state from east to west across the northern part of the state, draining into the Humboldt Sink near Lovelock. Several rivers drain from the Sierra Nevada eastward, including the Walker and Carson rivers. All of these rivers are endorheic basins, ending in Walker Lake, Pyramid Lake, the Carson Sink, respectively. However, not all of Nevada is within the Great Basin.
Tributaries of the Snake River drain the far north, while the Colorado River, which forms much of the boundary with Arizona, drains much of southern Nevada. The mountain ranges, some of which have peaks above 13,000 feet, harbor lush forests high above desert plains, creating sky islands for endemic species; the valleys are no lower in elevation than 3,000 feet, while some in central Nevada are above 6,000 feet. The southern third of the state, where the Las Vegas area is situated, is within the Mojave Desert; the area is closer to the Arizona Monsoon in the summer. The terrain is lower below 4,000 feet, creating conditions for hot summer days and cool to chilly winter nights. Nevada and California have by far the longest diagonal line as a state boundary at just over 400 miles; this line begins in Lake Tahoe nearly
Lake Mead is a man made lake that lies on the Colorado River, about 24 mi from the Las Vegas Strip, southeast of the city of Las Vegas, Nevada, in the states of Nevada and Arizona. It is the largest reservoir in the United States in terms of water capacity. Formed by the Hoover Dam on September 30, 1935, the reservoir serves water to the states of Arizona and Nevada, as well as some of Mexico, providing sustenance to nearly 20 million people and large areas of farmland. At maximum capacity, Lake Mead is 112 miles long, 532 feet at its greatest depth, has a surface elevation of 1,221.4 feet above sea level and 247 square miles of surface area, contains 26.12 million acre feet of water. The lake has not reached full capacity, since 1983 due to a combination of drought and increased water demand; as of August 2017, Lake Mead was at 40% of full capacity with 10 million acre feet of held water. It has been smaller than Lake Powell since 2013; the lake was named after Elwood Mead, the commissioner of the U.
S. Bureau of Reclamation from 1924 to 1936, during the planning and construction of the Boulder Canyon Project that created the dam and lake. Lake Mead was established as the Boulder Dam Recreation Area in 1936 administrated by the National Park Service; the name was changed to the Lake Mead National Recreation Area in 1964, Lake Mohave and the Shivwits Plateau were added to its jurisdiction. Both lakes and the surrounding area offer year-round recreation options; the accumulated water from Hoover Dam forced the evacuation of several communities, most notably St. Thomas, whose last resident left the town in 1938; the ruins of St. Thomas are sometimes visible. Lake Mead covered the sites of the Colorado River landings of Callville and Rioville and the river crossing of Bonelli's Ferry, between Arizona and Nevada. At lower water levels, a high-water mark or "bathtub ring" is visible in photos that show the shoreline of Lake Mead; the bathtub ring is white because of the leaching of minerals on submerged surfaces.
Nine main access points to the lake are available. On the west are three roads from the Las Vegas metropolitan area. Access from the northwest from Interstate 15 is through the Valley of Fire State Park and the Moapa River Indian Reservation to the Overton Arm of the lake; the lake is divided into several bodies. The large body closest to the Hoover Dam is Boulder Basin; the narrow channel, once known as Boulder Canyon and is now known as The Narrows, connects Boulder Basin to Virgin Basin to the east. The Virgin River and Muddy River empty into the Overton Arm, connected to the northern part of the Virgin Basin; the next basin to the east is Temple Basin, following, Gregg Basin, connected to the Temple Basin by the Virgin Canyon. When the lake levels are high enough, a section of the lake farther upstream from the Gregg Basin is flooded, which includes Grand Wash Bay, the Pearce Ferry Bay and launch ramp, about 55 miles of the Colorado River within the lower Grand Canyon, extending to the foot of 240 Mile Rapids.
In addition, two small basins, the Muddy River Inlet and the Virgin River Basin, are flooded when the lake is high enough where these two rivers flow into the lake. As of February 2015, these basins remain dry. Jagged mountain ranges surround the lake, offering a scenic backdrop at sunset. Two mountain ranges are within view of the Boulder Basin, the River Mountains, oriented northwest to southeast and the Muddy Mountains, oriented west to northeast. Bonelli Peak lies to the east of the Virgin Basin. Las Vegas Bay is the terminus for the Las Vegas Wash, the sole outflow from the Las Vegas Valley. Lake Mead receives the majority of its water from snow melt in the Colorado and Utah Rocky Mountains. Inflows to the lake are moderated by the upstream Glen Canyon Dam, required to release 8.23 million acre feet of water each year to Lake Mead. Hoover Dam is required to release 9 million acre feet of water each year, with the difference made up by tributaries that join the Colorado below Glen Canyon or flow into Lake Mead.
Outflow, which includes evaporation and delivery to Arizona, California and Mexico from Lake Mead are in the range of 9.5 to 9.7 million acre feet, resulting in a net annual deficit of about 1.2 million acre feet. Before the filling of Lake Powell behind Glen Canyon Dam, the Colorado River flowed unregulated into Lake Mead, making Mead more vulnerable to drought. From 1953 to 1956, the water level fell from 1,200 to 1,085 feet. During the filling of Lake Powell from 1963 to 1965, the water level fell from 1,205 to 1,090 feet. Multiple wet years from the 1970s to the 1990s filled both lakes to capacity, reaching a record high of 1,225 feet in the summer of 1983. In these decades prior to 2000, Glen Canyon Dam released more than the required 8.23 million acre feet to Lake Mead each year. This allowed Lake Mead to maintain a high water level despite releasing more water than it is contracted for. However, since 2000, the Colorado River has experienced persistent drought, with average or above-average conditions occurring in only five years in the first 16 years of the 21st century.
Although Glen Canyon was able to meet its required minimum release until 2014, the water level in Lake Mead has declined. The decreas
Las Vegas Wash
Las Vegas Wash is a 12-mile-long channel which feeds most of the Las Vegas Valley's excess water into Lake Mead. The wash is sometimes called an urban river, it exists in its present capacity because of an urban population; the wash works in a systemic conjunction with the pre-existing wetlands that formed the oasis of the Las Vegas Valley. The wash is fed by urban runoff, shallow ground water, reclaimed water, stormwater; the wetlands of the Las Vegas Valley act as the kidneys of the environment, cleaning the water that runs through it. The wetlands filter out harmful residues from fertilizers and other contaminants that can be found on the roadways and in the surrounding desert. Near its terminus at Las Vegas Bay, the wash passes under the man made Lake Las Vegas through two 7-foot pipes. Before development in the valley above the wash, it was able to contain the flows from rain water that fell in the valley and hills above; when the first sewage treatment plant went on line, the flows began increasing to the point that the channel expanded in size as the increased flows eroded the wash's stream-banks.
This erosion deepened the channel draining one of the largest desert wetlands in the U. S. southwest as the water flowed down the channel rather than flooding the wetlands area. This has had several consequences among them, increased flows of silt into Lake Mead, fewer migratory birds, reduced water polishing from the native plants, infestation of invasive plant species such as African Tamarisk and Sahara Mustard; the major natural sources that feed the wash are: Duck Creek Las Vegas Creek Flamingo Wash Pittman Wash Monson Channel Sloan Channel Meadows Detention Basin Tule Springs Wash Clark County Wetlands Park List of tributaries of the Colorado River Las Vegas Wash Coordination Committee Media related to Las Vegas Wash at Wikimedia Commons Las Vegas Wash Watershed
Henderson the City of Henderson, is a city in Clark County, United States, about 16 miles southeast of Las Vegas. It is the second-largest city in Nevada, after Las Vegas, with an estimated population of 302,539 in 2017; the city is part of the Las Vegas metropolitan area. Henderson occupies the southeastern end of the valley, at an elevation of 1,864 feet; the township of Henderson first emerged in the 1940s during World War II with the building of the Basic Magnesium Plant. Henderson became the main supplier of magnesium in the United States, called the "miracle metal" of World War II; the plant supplied the US War Department with magnesium for incendiary munition casings and airplane engines and other parts. A quarter of all US wartime magnesium came from the Henderson Plant to strengthen aluminum, using 25% of Hoover Dam's power to separate the metal from its ore by electrolysis. Mayor Jim Gibson's grandfather, Fred D. Gibson, was one of the original engineers sent to Great Britain to learn the secret of creating the "miracle metal" which would help the United States and its allies win the war.
The British liaison officer sent to Henderson, Major Charles Ball, had a street named after him. There was some concern "Ball St," would sound improper, so the street was named "Major Avenue". Although "born in America's defense", Henderson's future after World War II was uncertain. In 1947, magnesium production was no longer necessary for defense, most of BMI's 14,000 employees moved away. Enrollment in the school system was reduced by two thirds, well over half the townsite houses, built to house plant workers, became vacant. In 1947, the United States War Asset Administration offered Henderson for sale as war surplus property. In an effort to save the city, the Nevada Legislature spent a weekend visiting Henderson, evaluating the possibility of state administration of Basic Magnesium. Within days of the visit, the legislators unanimously approved a bill that gave Nevada's Colorado River Commission the authority to purchase the industrial plants. Governor Vail Pittman signed the bill on March 27, 1947, helping save Henderson from becoming war surplus property.
With the help of local industry, Henderson was incorporated on April 16, 1953 as the City of Henderson. On May 23, 1953, with its population of 7,410, elected Dr. Jim French as the first mayor. Only about 13 square miles in size, the city began to grow, reaching over 94 square miles in size today. In 1988, the Pacific Engineering and Production Company of Nevada rocket fuel factory, in the modern-day Gibson Springs neighborhood of Henderson, caught fire; the blaze engulfed the factory, spewing rocket fuel and toxic fumes from the building obliterating it in a massive explosion, followed by six smaller explosions. These explosions sent shockwaves throughout Henderson and parts of the Las Vegas Valley that shattered glass and damaged buildings; the explosions caused earthquakes, some of which measured over 3.0 on the Richter magnitude scale. Two people were killed and 372 were injured; the events of the PEPCON factory disaster spurred development in Henderson years from its historical industrial development to residential and commercial development.
There are now no signs of the explosion. Today, the site consists of office buildings. In February 2018, the Oakland Raiders announced the signing of a deal for 55 acres of land near Henderson Executive Airport, on which will be built the team's executive offices and practice facility. Henderson is 16 miles southeast of downtown Las Vegas at 36°2′23″N 114°58′52″W. According to the United States Census Bureau, the city has a total area of 107.7 square miles, all land. The city is in the Mojave Desert with vegetation typical of the Mojave; the mountains that surround Henderson have gentle slopes. The McCullough Range is closest to the city; these mountains reach an average height of about 3,800 feet. The landscape consists of the desert. Residential neighborhoods in Henderson include Anthem, Anthem Country Club, Black Mountain Vistas, Calico Ridge, Champion Village, The Fountains, Grand Legacy, Green Valley, Green Valley Estates, Green Valley Ranch, Hillsboro Heights, Lake Las Vegas, MacDonald Highlands, MacDonald Ranch, Madeira Canyon, Club at Madeira Canyon, Roma Hills, Seven Hills, Sun City Anthem, Sun City MacDonald Ranch, Tuscany Residential Village, Whitney Ranch.
Henderson is classified as having a hot desert climate in the Köppen climate classification. It has mild winters and hot summers. Snow can fall in the winter; the monsoon can bring storms in the summer, which can cause thunderstorms. The hottest month is July and the coldest month is December. On average there are 292 clear days per year. At the census of 2010, 257,729 people resided in Henderson; the racial makeup was 76.9% White, 5.1% African American, 0.7% Native American, 7.2% Asian, 0.6% Pacific Islander, 4.8% from two or more races. Hispanic or Latino of any race were 14.9% of the population and 68.7% of the population was non-Hispanic White. According to the 2000 census, there were 175,381 people, 66,331 households, 47,095 families residing in the city; the population density was 2,200.8 people per square mile. There were 71,149 housing units at an average density of 892.8 per squar
A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is called a gulf, sound, or bight. A cove is a type of smaller bay with narrow entrance. A fjord is a steep bay shaped by glacial activity. A bay can be the estuary of a river, such as the Chesapeake Bay, an estuary of the Susquehanna River. Bays may be nested within each other; some large bays, such as the Bay of Bengal and Hudson Bay, have varied marine geology. The land surrounding a bay reduces the strength of winds and blocks waves. Bays were significant in the history of human settlement because they provided safe places for fishing, they were important in the development of sea trade as the safe anchorage they provide encouraged their selection as ports. The United Nations Convention on the Law of the Sea called the Law of the Sea, defines a bay as a well-marked indentation whose penetration is in such proportion to the width of its mouth as to contain land-locked waters and constitute more than a mere curvature of the coast.
An indentation shall not, however, be regarded as a bay unless its area is as large as, or larger than, that of the semi-circle whose diameter is a line drawn across the mouth of that indentation. There are various ways; the largest bays have developed through plate tectonics. As the super-continent Pangaea broke up along curved and indented fault lines, the continents moved apart and left large bays. Bays form through coastal erosion by rivers and glaciers. A bay formed by a glacier is a fjord. Rias are characterised by more gradual slopes. Deposits of softer rocks erode more forming bays, while harder rocks erode less leaving headlands.
