San Juan River (Colorado River tributary)
The San Juan River is a major tributary of the Colorado River in the southwestern United States, providing the chief drainage for the Four Corners region of Colorado, New Mexico and Arizona. Originating as snowmelt in the San Juan Mountains of Colorado, it flows 383 miles through the deserts of northern New Mexico and southeastern Utah to join the Colorado River at Glen Canyon; the river drains a high, arid region of the Colorado Plateau and along its length it is the only significant source of fresh water for many miles. The San Juan is one of the muddiest rivers in North America, carrying an average of 25 million US tons of silt and sediment each year; the San Juan formed the border between the territory of the Navajo in the south and the Ute in the north. Although Europeans explored the Four Corners region at least as early as the 1700s, it was not until the gold and silver booms of the 1860s when settlers arrived in large numbers from the eastern United States. After heated conflicts over land, the Native Americans were forced into reservations, where their descendants live today.
During the 20th century, intensive drilling in the fossil fuel-rich San Juan Basin and uranium mining along the lower river in Utah generated serious concerns about water quality, particular on the Navajo Nation where the river is a crucial source of water for irrigation. Runoff from abandoned gold and silver mines is a major issue, as occurred in the 2015 Gold King Mine waste water spill into the Animas River, the main tributary of the San Juan; the U. S. federal government has built a number of large dams in the San Juan River system to control floods, provide irrigation and domestic water supply. In addition, the lower part of the river is inundated by Lake Powell, one of the largest reservoirs in the United States. Efficient management is crucial to ensuring enough water supply for not just farms and urban areas, but recreational boating and environmental restoration. However, heavy water use has reduced the flow of the San Juan River, by as much as 25 percent since pre-development conditions.
The San Juan River begins in Archuleta County, Colorado at the confluence of its East and West Forks. Both forks originate above elevations of 10,000 feet in the eastern San Juan Mountains in the San Juan National Forest; the river flows southwest through the foothills of the Rocky Mountains through the town of Pagosa Springs and reaches the Navajo Lake reservoir just north of the New Mexico border, near Arboles, Colorado. Below the Navajo Dam the San Juan River flows west through a narrow farming valley in high desert country of the Colorado Plateau. At Farmington, New Mexico it is joined from the north by its main tributary, the Animas River, which rises in the San Juan Mountains near Silverton, Colorado. From there it flows west through the Navajo Nation, turning northwest near Shiprock and its namesake monolith, crossing briefly back into southwest Colorado before entering southeastern Utah. West of Bluff, Utah the river slices through the Comb Ridge and enters a series of rugged winding canyons over 1,500 feet in depth.
The lower 70 miles of the San Juan River, in a remote portion of the Glen Canyon National Recreation Area, are flooded by Lake Powell, formed by Glen Canyon Dam on the Colorado River. The San Juan joins the Colorado in San Juan County, Utah at a point about 15 miles to the north of Navajo Mountain and 80 miles northeast of Page, Arizona. Tributaries of the upper San Juan River above Navajo Dam include the Rio Blanco and the Navajo River, the Piedra River and Los Pinos River which join the San Juan in Navajo Lake. In addition to the Animas River, several major tributaries join below Farmington including the La Plata River and Mancos River in New Mexico, McElmo Creek in Utah; the San Juan has a number of seasonal tributaries that drain arid regions of the Colorado Plateau. These include the Cañon Largo and Chaco River in New Mexico, the Montezuma Creek and Chinle Creek in Utah; the northern tributaries of the San Juan River, which originate in the San Juan Mountains, are snowmelt-driven with the highest flows between March and June.
Southern tributaries such as the Chaco River are ephemeral but can carry large volumes of water during flash floods. According to the U. S. Bureau of Reclamation, the average unimpaired runoff or natural flow of the San Juan River basin over the 1906–2014 period was about 2,900 cubic feet per second, 2,101,000 acre feet per year; the maximum was 6,200 cubic feet per second, 4,466,000 acre feet, in 1941, the minimum was 710 cubic feet per second, 513,000 acre feet, in 2002. Heavy water use has decreased the flow of the river since the early 20th century; the U. S. Geological Survey stream gaging station at Bluff, Utah recorded an average annual discharge of 2,152 cubic feet per second, or 1,559,000 acre feet, for the 1915–2013 period. Before the construction of major dams to regulate the river, it sometimes dried up in the summer, as it did in 1934 and 1939; the maximum flow was 70,000 cubic feet per second on September 10, 1927. The great flood of October 1911, which remains the largest flood on the San Juan River on record, occurred before the USGS began measuring streamflow here.
Based on observations of water depth and debris deposits, the 1911 flood may have reached a peak of 148,000 cubic feet per second (4,200
Fraser River (Colorado)
The Fraser River is a tributary of the Colorado River 32.5 miles long, in north central Colorado in the United States. It drains large portion of the Middle Park basin in Grand County in the Rocky Mountains west of Boulder and southwest of Rocky Mountain National Park, it rises at the continental divide on the north side of Berthoud Pass in the Arapaho National Forest. It flows NNW past Winter Park and Tabernash, joins the Colorado River from the south two miles west of Granby; the Fraser holds wild rainbows, browns and cutthroats. The Fraser River starts near Berthoud Pass; as it runs north for its first 8 miles, it is publicly accessible. The river is shallow here, but worthy of fishing. From Winter Park to Fraser, the river can be accessed by the Fraser River Trail, from USFS campgrounds, or road turnouts; the only exception is. You can go fishing in the forested lands. Access to the Fraser River is limited downstream from the town of Fraser; some of the best fishing is in the canyon downstream from Tabernash, however this is on private land.

Eagle River (Colorado)
The Eagle River is a tributary of the Colorado River 60.5 miles long, in west central Colorado in the United States. It rises in southeastern Eagle County, at the continental divide, flows northwest past Gilman, Avon. Near Wolcott, it turns west, flowing past Eagle and Gypsum, joins the Colorado at Dotsero, in western Eagle County; the Eagle is navigable by typical small river craft upstream to Vail in most years. Its flow ranges from 200 cu ft/s in late summer of dry years to 7,000 cu ft/s during spring runoff. Acid mine drainage from the abandoned Eagle Mine has entered the river.

North America is a continent within the Northern Hemisphere and all within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, to the southeast by South America and the Caribbean Sea. North America covers an area of about 24,709,000 square kilometers, about 16.5% of the earth's land area and about 4.8% of its total surface. North America is the third largest continent by area, following Asia and Africa, the fourth by population after Asia and Europe. In 2013, its population was estimated at nearly 579 million people in 23 independent states, or about 7.5% of the world's population, if nearby islands are included. North America was reached by its first human populations during the last glacial period, via crossing the Bering land bridge 40,000 to 17,000 years ago; the so-called Paleo-Indian period is taken to have lasted until about 10,000 years ago. The Classic stage spans the 6th to 13th centuries.
The Pre-Columbian era ended in 1492, the transatlantic migrations—the arrival of European settlers during the Age of Discovery and the Early Modern period. Present-day cultural and ethnic patterns reflect interactions between European colonists, indigenous peoples, African slaves and their descendants. Owing to the European colonization of the Americas, most North Americans speak English, Spanish or French, their culture reflects Western traditions; the Americas are accepted as having been named after the Italian explorer Amerigo Vespucci by the German cartographers Martin Waldseemüller and Matthias Ringmann. Vespucci, who explored South America between 1497 and 1502, was the first European to suggest that the Americas were not the East Indies, but a different landmass unknown by Europeans. In 1507, Waldseemüller produced a world map, in which he placed the word "America" on the continent of South America, in the middle of what is today Brazil, he explained the rationale for the name in the accompanying book Cosmographiae Introductio:... ab Americo inventore... quasi Americi terram sive Americam.
For Waldseemüller, no one should object to the naming of the land after its discoverer. He used the Latinized version of Vespucci's name, but in its feminine form "America", following the examples of "Europa", "Asia" and "Africa". Other mapmakers extended the name America to the northern continent, In 1538, Gerard Mercator used America on his map of the world for all the Western Hemisphere; some argue that because the convention is to use the surname for naming discoveries, the derivation from "Amerigo Vespucci" could be put in question. In 1874, Thomas Belt proposed a derivation from the Amerrique mountains of Central America. Marcou corresponded with Augustus Le Plongeon, who wrote: "The name AMERICA or AMERRIQUE in the Mayan language means, a country of perpetually strong wind, or the Land of the Wind, and... the can mean... a spirit that breathes, life itself." The United Nations formally recognizes "North America" as comprising three areas: Northern America, Central America, The Caribbean.
This has been formally defined by the UN Statistics Division. The term North America maintains various definitions in accordance with context. In Canadian English, North America refers to the land mass as a whole consisting of Mexico, the United States, Canada, although it is ambiguous which other countries are included, is defined by context. In the United States of America, usage of the term may refer only to Canada and the US, sometimes includes Greenland and Mexico, as well as offshore islands. In France, Portugal, Romania and the countries of Latin America, the cognates of North America designate a subcontinent of the Americas comprising Canada, the United States, Mexico, Greenland, Saint Pierre et Miquelon, Bermuda. North America has been referred to by other names. Spanish North America was referred to as Northern America, this was the first official name given to Mexico. Geographically the North American continent has many subregions; these include cultural and geographic regions. Economic regions included those formed by trade blocs, such as the North American Trade Agreement bloc and Central American Trade Agreement.
Linguistically and culturally, the continent could be divided into Latin America. Anglo-America includes most of Northern America and Caribbean islands with English-speaking populations; the southern North American continent is composed of two regions. These are the Caribbean; the north of the continent maintains recognized regions as well. In contrast to the common definition of "North America", which encompasses the whole continent, the term "North America" is sometimes used to refer only to Mexico, the United States, Greenland; the term Northern America refers to the northern-most countries and territories of North America: the United States, Bermuda, St. Pierre and Miquelon and Greenland. Although the term does not refer to a unifie
Tomichi Creek is a 71.8-mile-long tributary of the Gunnison River in Gunnison County, Colorado. Tomichi Creek originates north and west of Monarch Pass and flows to the southwest along the base of Monarch Mountain. Congress Creek drains into Tomichi west of Old Monarch Pass. Agape Creek flows into Tomichi just north of Sargents. Just below Sargents, Long Branch Creek, flowing out of Baldy Lake from the south, enters Tomichi Creek which takes a westward course where Needle Creek Reservoir drains into Tomichi east of Doyleville. Hot Springs Reservoir drains down Wanita Canyon flowing into Tomichi Creek just west of Doyleville; the Tomichi Valley is a semi-wide valley allowing Tomichi Creek to meander and split into several waterways creating an excellent livestock range and being private ranch lands. At Parlin, Quartz Creek flows from Ohio into Tomichi Creek. Tomichi continues its westward journey northwest, where the Cochetopa Creek drains into Tomichi at State Highway 114 from the south at the intersection of U.
S. continues west to Gunnison where it enters the Gunnison River. A map can be viewed at the BLM Colorado website here. Tomichi Creek State Wildlife Area is a gated public access with parking located at the east end of the runway at Gunnison-Crested Butte Regional Airport; this area provides fishing on private lands without required permission. Access to hiking W Mountain is provided. Tomichi flows through private property with a one-mile stretch of public access just off US 50 below Sargents at the narrow part of the canyon. Snowblind Campground, upstream nearly two miles toward Whitepine, offers another public access to Tomichi Creek. There are certain sections of Marshall Pass Road that takes off from US 50 at Sargents which offers public fishing areas and access to Needle Creek Reservoir and Razor Creek takes off from US 50 near Doyleville onto County Road 46. There are several picnic areas with parking on the Cochetopa Creek along State Hwy 114 around mile mark 12 and 5 miles upstream. Beyond that signs designate state stocked requires permission to fish.
In late summer the creek yields brown trout. Near the summit of State Hwy 114 a sign reads National Forest Access - Old Agency, turning south on this gravel road accesses Cochetopa Creek and the middle of the Colorado Division of Wildlife's Coleman Easement five miles of Cochetopa Creek, two miles of Los Pinos Creek and one-half mile of lower Archuleta Creek are open to the public, yet are private lands which should be respected; these streams have produced wild trout for the avid angler. Located below Dome Lakes, Coleman Easement is accessible by automobile and other vehicles and designated as Wild Trout water by the Colorado Division of Wildlife. Rainbow trout up to 15 inches are angled by small stream tactics using dry flies. Spinners and heavy nymphs are troubled by the streambed vegetation. Stocked rainbows found in the private stretches require permission to fish. List of rivers of Colorado List of tributaries of the Colorado River
The Fryingpan River is a tributary of the Roaring Fork River 42 miles long, in west central Colorado in the United States. The reason for the unusual name of the river is that when a group of trappers were attacked by a band of Ute Indians, only two men survived, one of whom was injured. Leaving his wounded friend in a cave close by, the last man left to summon help, but not before hanging a frying pan in a tree so that he could find the cave again on his return, it rises in northeastern Pitkin County, in the White River National Forest in the Sawatch Mountains along the western side of the continental divide. It flows westward along the county line between Eagle County. Below Meredith, it is dammed to form the Ruedi Reservoir, it joins the Roaring Fork below Basalt. A portion of the river's water is diverted to the east side of the continental divide for irrigation and drinking water via the Fryingpan-Arkansas Project.
