What is the longest fork in the American River?
North Fork American River
The North Fork American River is the longest branch of the American River in Northern California. It is long from its source at the crest of the Sierra Nevada, near Lake Tahoe, to its mouth at Folsom Lake northeast of Sacramento. Prior to the construction of Folsom Dam the river was about longer making for a total length of .
Brazos River
The Brazos River ( ), called the "Rio de los Brazos de Dios" (translated as "The River of the Arms of God") by early Spanish explorers, is the 11th-longest river in the United States at from its headwater source at the head of Blackwater Draw, Curry County, New Mexico to its mouth at the Gulf of Mexico with a drainage basin. Being one of Texas' largest rivers, it is sometimes used to mark the boundary between East Texas and West Texas.
Fort Randall Dam
Fort Randall Dam is a long earthen dam which spans the Missouri River and impounds Lake Francis Case, the 11th largest reservoir in the U.S. The dam joins Gregory and Charles Mix County, South Dakota a distance of 880 river miles (1,416 km) upstream of St. Louis, Missouri, where the river joins the Mississippi River. The dam and Hydroelectric power plant were constructed by and are currently operated by the U.S. Army Corps of Engineers.
Locust Fork of the Black Warrior River
History
The Locust Fork is an ancient river with a surprising history. The river and its tributaries have carved a path through the surrounding ridges of sandstone and chert at least a dozen times - geological evidence that this river is older than the hills through which it flows.
That geology demonstrates that across the millennia as the Appalachians and other uplifts of the land slowly took place, the river cut through. Today it exhibits hairpin curves bordered by steep bluffs, called “entrenched meanders”. Together the river and ridges have created an array of habitats for a distinctively rich diversity of life. (Adapted from Jim Lacefield, author of “Lost Worlds in Alabama Rocks”.)
In spite of threats, the Locust Fork remains free-flowing, preserving some of that rich bio-diversity, although human activity has caused many extinctions of rare and unusual species.
The river provided Native Americans ample food and shelter, resulting in abundant artifacts in the watershed. 
The river’s winding course caused the early white settlers to build many bridges, some of which survive from the past: Swann Covered Bridge https://en.wikipedia.org/wiki/Swann_Covered_Bridge Horton Mill Covered Bridge
https://en.wikipedia.org/wiki/Horton_Mill_Covered_Bridge and Easly Covered Bridge
Today just in Blount County 115 bridges longer than 20 feet currently in operation cross the Locust Fork River.
Settlers also built grain mills in almost every valley. Most of them are gone.

New River Gorge Bridge
The New River Gorge Bridge is a steel arch bridge long over the New River Gorge near Fayetteville, West Virginia, in the Appalachian Mountains of the eastern United States. With an arch long, the New River Gorge Bridge was for many years the world's longest single-span arch bridge; it is now the fourth longest. Part of U.S. Route 19, its construction marked the completion of Corridor L of the Appalachian Development Highway System. The bridge is crossed by an average of 16,200 motor vehicles per day.
Hodge Decision
The American River is the second largest tributary of the Sacramento River and is divided into three sections, Lower Fork; Middle Fork; Upper Fork. Together, these sections span 120 miles from the crest of the Sierra Nevada, through the foothills, and converges with the Sacramento River in Sacramento, California. The Lower Fork of the American River begins at the outlet of Folsom Lake and flows westward until its confluence with the Sacramento River. The drainage basin of the American River is approximately 1,900 square miles. There are several activities popular to the American River including: whitewater rafting, fishing, boating. In addition, the river also acts as a source of hydroelectric power, municipal water, and flood control from Folsom Dam. Several water agencies in Sacramento divert water from the American River via surface water diversions and groundwater wells in order to supply enough water for its customers. These diversions have resulted in several negative implications on the Lower American River fishery. Therefore, the Hodge Decision was concocted in order to protect the river's salmon and steelhead populations and preserve natural river morphology.
Port Hudson State Historic Site
The Port Hudson State Historic Site is located on the Mississippi River north of Baton Rouge in East Feliciana Parish, Louisiana, just outside the limits of Port Hudson and in the vicinity of Jackson. The site preserves a portion of the fortifications and battle area of the longest siege in American history, during the American Civil War from May 23 through July 9, 1863. The state of Louisiana maintains the site, which includes a museum about the siege, artillery displays, redoubts, and interpretive plaques. Living history re-enactments are held each year. It was designated a National Historic Landmark in 1974, significant as the first place where African-American military units fought for the Union Army under African-American field leadership.
South Fork American River
Rafting and Kayaking
American River
The South Fork is long. It originates at Echo Summit near Echo Lake south of Lake Tahoe in El Dorado County, just south of where U.S. Route 50 makes a sharp curve northward to descend into Tahoe Valley. The South Fork has multi-use recreational areas, including the Rubicon Trail for motorized adventuring and whitewater rafting venues. The South Fork also features the historic town of Coloma, where the California Gold Rush began in 1848. Trout fishing and recreational gold panning are popular activities on the South Fork.
Susquehanna River
The Susquehanna River (; Lenape: Siskëwahane) is a major river located in the northeastern and mid-Atlantic United States. At long, it is the longest river on the East Coast of the United States that drains into the Atlantic Ocean. With its watershed, it is the 16th-largest river in the United States, and the longest river in the early 21st-century continental United States without commercial boat traffic.
American Fork, Utah
Settlers changed the name from Lake City to American Fork in 1860. It was renamed after the American Fork River which runs through the city, as well as to avoid confusion with Salt Lake City. Most residents were farmers and merchants during its early history. By the 1860s, American Fork had established a public school, making it the first community in the territory of Utah to offer public education to its citizens. In the 1870s, American Fork served as a rail access point for mining activities in American Fork Canyon. American Fork had "a literal social feud" with the town of Lehi due to the Utah Sugar Company choosing Lehi as the factory building site in 1890, instead of American Fork. There were several mercantile businesses in American Fork, such as the American Fork Co-operative Association and Chipman Mercantile. For several decades in the 1900s, raising chickens (and eggs) was an important industry in the city. In 1892, Joseph Forbes organized the schools in American Fork, and the Forbes school is named after him.
Mississippi River System
The Missouri River is a long stream that originates in southwest Montana and flows southeasterly for 2,522 miles; passing through six states before finally entering the Mississippi River at St. Louis. The Missouri River is the longest river on the North American continent. The Missouri River was one of the main routes for the watershed expansion of the United States during the 19th century.
Middle Fork American River
The main stem of the river begins along the Sierra Crest, on the south flank of Granite Chief near Squaw Valley Ski Resort west of Lake Tahoe. It flows west then southwest into French Meadows Reservoir, which is impounded by the L.L. Anderson Dam. Below the dam the Middle Fork enters a rugged and inaccessible canyon more than deep. About downstream, the Middle Fork flows into the Ralston Afterbay, where it is joined from the east by the Rubicon River. Directly below this point, the North Fork of the Middle Fork American River joins from the north. The Middle Fork then flows southwest, past Foresthill, through the Auburn State Recreation Area, and into the North Fork directly below the Foresthill Bridge and above Highway 193. Below this confluence the North Fork flows a further to the Folsom Lake reservoir above Sacramento. Although nominally a tributary of the North Fork, the Middle Fork has a greater flow and drains a much larger watershed of .
Colorado River
At the lower end of Grand Canyon, the Colorado widens into Lake Mead, the largest reservoir in the continental United States, formed by Hoover Dam on the border of Arizona and Nevada. Situated southeast of metropolitan Las Vegas, the dam is an integral component for management of the Colorado River, controlling floods and storing water for farms and cities in the lower Colorado River basin. Below the dam the river passes under the Mike O'Callaghan–Pat Tillman Memorial Bridge – which at nearly above the water is the highest concrete arch bridge in the Western Hemisphere – and then turns due south towards Mexico, defining the Arizona–Nevada and Arizona–California borders.
After leaving the confines of the Black Canyon, the river emerges from the Colorado Plateau into the Lower Colorado River Valley (LCRV), a desert region dependent on irrigation agriculture and tourism and also home to several major Indian reservations. The river widens here to a broad, moderately deep waterway averaging wide and reaching up to across, with depths ranging from . Before channelization of the Colorado in the 20th century, the lower river was subject to frequent course changes caused by seasonal flow variations. Joseph C. Ives, who surveyed the lower river in 1861, wrote that "the shifting of the channel, the banks, the islands, the bars is so continual and rapid that a detailed description, derived from the experiences of one trip, would be found incorrect, not only during the subsequent year, but perhaps in the course of a week, or even a day."
North Fork Flathead River
Although the North Fork is designated as a National Wild and Scenic River (1975) in the United States, its greater length in BC (, not including headwaters forks) is not. Water in the BC section remains relatively pure as there are no permanent residents or livestock in this drainage north of the border.
Silver Fork American River
It begins in Amador County above Silver Lake near Kit Carson, just west of Kirkwood Mountain Resort, at an elevation of almost 8,000 feet. After exiting Silver Lake near Carson Pass Highway, Silver Fork American River flows west through El Dorado County in the Eldorado National Forest for almost four miles where it receives its main tributary, Caples Creek. For the remaining 8.5 miles, it flows northwest paralleling Silver Fork Road passing numerous campgrounds such as Caples Creek, Silver Fork, Silver Fork Ranch, Gray Rock, and China Flat. It finally joins the South Fork American River just west of the town of Kyburz.
American Fork River
The city of American Fork is named after this river.
The description "American" in the river's name is to distinguish it from the Spanish Fork River that also originates in the Wasatch Range; alternatively, it could have been named after the American Fur Company.
Nooksack River
The Nooksack River is a river in the northwest part of the U.S. state of Washington. It drains an area of the Cascade Range around Mount Baker, near the Canada–US border. The lower river flows through a fertile agricultural area before emptying into Bellingham Bay and, via the Strait of Juan de Fuca and the Strait of Georgia, the Pacific Ocean. The river begins in three main forks, the North Fork, Middle Fork, and South Fork. The North Fork is sometimes considered the main river. Including the North Fork, the Nooksack is approximately long. All three forks originate in the Mount Baker Wilderness.
South Fork American River
The river begins at Nebelhorn near Johnson Pass about south of Lake Tahoe. From there it flows west for , past the towns of Kyburz, Pollock Pines and Coloma, before emptying into Folsom Lake, the reservoir formed by the Folsom Dam. The North Fork American River also flows into the lake, and the combined rivers form the American River proper, which flows from the dam southwest to a confluence with the Sacramento River.
North Fork Feather River
The fork's portion of the Feather River Canyon is notable as part of the Feather River Route, and the railroad's North Fork Bridge near the river's mouth is the longest reinforced concrete bridge in the US.
Mulberry Fork of the Black Warrior River
Mulberry Fork is a tributary of the Black Warrior River, long, in the U.S. state of Alabama. The Mulberry Fork is one of three forks, along with the Locust Fork and the Sipsey Fork, that join to form the Black Warrior. It drains part of the southernmost end of the Appalachian Mountains north and west of Birmingham in the drainage basin of the Mobile River.
North Fork Bridge (California)
It is the longest reinforced concrete bridge in the United States.
Aqueduct (water supply)
In modern times, the largest aqueducts of all have been built in the United States to supply the country's biggest cities. The Catskill Aqueduct carries water to New York City over a distance of 120 miles (190 km), but is dwarfed by aqueducts in the far west of the country, most notably the Colorado River Aqueduct, which supplies the Los Angeles area with water from the Colorado River nearly 400 km to the east and the 701.5 mi (1,129 km) California Aqueduct, which runs from the Sacramento-San Joaquin River Delta to Lake Perris. The Central Arizona Project is the largest and most expensive aqueduct constructed in the United States. It stretches 336 miles from its source near Parker, Arizona to the metropolitan areas of Phoenix and Tucson. An aqueduct in New Zealand, "the Oamaru Borough Race" was constructed in the late 19th century to deliver water (and water-power) about 50 km from the Waitaki River at Kurow to the coastal town of Oamaru.
Hoquiam River
The East, West, and Middle Forks all originate north of Grays Harbor and flow generally south. The East Fork Hoquiam River is the longest, at long. It joins the West Fork to form the main stem Hoquiam River near Hoquiam and Aberdeen. The West Fork and Middle Fork are both long. The West Fork is paralleled by U.S. Route 101. It joins the East Fork form the main stem Hoquiam River. The Middle Fork is a tributary of the West Fork.

American River
The Middle Fork is long. It originates a mere from the source of the North Fork on the south face of Granite Chief, between the summit and Emigrant Pass. It is characterized by somewhat broader steep canyons interspersed with reservoirs, waterfalls, and quiet riparian areas. The Middle Fork is used extensively for both motorized and non-motorized recreation, including fishing, white water adventuring, bicycling (mountain and road), horseback riding, trail running and hiking. It contains areas used for hydroelectric generation, mining, and agricultural timber cultivation and harvesting.
The Middle Fork features part of the Auburn State Recreation Area. The Western States Trail hosts multiple annual endurance events, including the Tevis Cup equestrian trail ride, and the world-famous Western States 100- Mile Trail Run, both beginning at Squaw Valley and leading to Auburn via remote wilderness trails.
South Fork American River
There is BLM land located off Highway 49 on the way to Auburn from Coloma with great hiking, biking and equestrian trails. Parking and use is free and it is a great way to experience the South Fork of the American River.
Missouri River
In the early stages of Pick–Sloan development, tentative plans were made to build a low dam on the Missouri at Riverdale, North Dakota and 27 smaller dams on the Yellowstone River and its tributaries. This was met with controversy from inhabitants of the Yellowstone basin, and eventually the USBR proposed a solution: to greatly increase the size of the proposed dam at Riverdale – today's Garrison Dam, thus replacing the storage that would have been provided by the Yellowstone dams. Because of this decision, the Yellowstone is now the longest free-flowing river in the contiguous United States. In the 1950s, construction commenced on the five mainstem dams – Garrison, Oahe, Big Bend, Fort Randall and Gavins Point – proposed under the Pick-Sloan Plan. Along with Fort Peck, which was integrated as a unit of the Pick-Sloan Plan in the 1940s, these dams now form what is known as the Missouri River Mainstem System.
Auburn Dam
Filling the Auburn Reservoir would result in a two-pronged, lake which would inundate numerous canyons and rapids of the North and Middle Forks of the American River. In 1981, the American River was acknowledged as the most popular recreational river in California. Over one million people visit the canyons of the North and Middle Forks of the American River each year to engage in various recreational activities, including kayaking, rafting, hiking, hunting, biking, horseback riding, gold mining, off-roading, and rock climbing. About 900,000 of these visitors go to the Auburn State Recreation Area, which includes the former dam site. The reservoir would inundate most of the Auburn recreation area, although some new recreational opportunities such as boating, water-skiing and deep water fishing would be created as a result of the new lake. Many trails, including those used by the Tevis Cup and Western States Endurance Run, would be submerged. The Auburn Reservoir would also result in the destruction of thousands of acres of riverine habitat, and the inundation of historic and archaeological sites.
Mississippi River System
The Red River is the 10th longest river in the United States with a length of 1,290 miles. It originates right outside of the Rocky Mountains and stretches through multiple states with the main portion of it located in Texas. The river also crosses through Oklahoma, Arkansas, and Louisiana where then it links into the Mississippi River. The Red River is mostly surrounded by rural farm land with the only surrounding major cities being Shreveport, Louisiana and Alexandria, Louisiana. The Red River is home to many oil fields with oil and gas production being one of the river's major aspects.
New River (Kanawha River tributary)
Few highways cross the gorge, with the most dramatic bridge by far being the New River Gorge Bridge on U.S. 19, a steel arch bridge spanning , with the roadway above the average level of the river. This structure is the third-longest single-arch bridge in the world, and is also the world's twenty-third-highest vehicular bridge, and the fourth highest in the Americas.
Auburn Dam
Auburn Dam was a proposed concrete arch dam on the North Fork of the American River east of the town of Auburn, California in the United States, on the border of Placer and El Dorado Counties. Slated to be completed in the 1970s by the U.S. Bureau of Reclamation, it would have been the tallest concrete dam in California and one of the tallest in the United States, at a height of and storing of water. Straddling a gorge downstream of the confluence of the North and Middle Forks of the American River and upstream of Folsom Lake, it would have regulated water flow and provided flood control in the American River basin as part of Reclamation's immense Central Valley Project.
Payette River
The Payette River is famous for its whitewater. Experts call the North Fork Class V run one of the most challenging river reaches in North America, if not the world. Kayaking on the lower North Fork from Smith's Ferry to Banks is world-class, easily viewed from state highway #55, which closely hugs its bank, primarily on the west side. The lower North Fork narrows and drops 1700 feet (518 m) in the 16 miles (26 km) above Banks, providing nearly endless Class V rapids (see International Scale of River Difficulty). The average gradient is per mile (21 m/km) with a maximum gradient of 200 ft/mile (38 m/km). The North Fork's flow rate is controlled through the Cascade Dam, completed in 1948, providing relatively warm water from the shallow Cascade Reservoir.
Kentucky River
The North Fork Kentucky River is approximately long. It rises on the western side of Pine Mountain, in the Appalachians of extreme southeastern Kentucky, in eastern Letcher County near the Virginia state line in Payne Gap, near the intersection of US 23 and US 119. It flows generally northwest, in a winding course through the mountainous Cumberland Plateau, past Whitesburg, Hazard and Jackson. It receives Rockhouse Creek at Blackey near its source. Approximately southeast of Hazard, it receives the Carr Fork. It receives Troublesome Creek at Haddix, southeast of Jackson. Three miles upstream from its confluence with the South Fork, it receives the Middle Fork. It joins the South Fork to form the Kentucky at Beattyville.
American Fork Railroad
The American Fork Railroad was a long narrow gauge railway with a gauge of from American Fork to Forest City in Utah, which operated from 1872 to 1878.
Connecticut River
The Connecticut River is the longest river in the New England region of the United States, flowing roughly southward for through four states. It rises at the U.S. border with Quebec, Canada, and discharges at Long Island Sound. Its watershed encompasses five U.S. states and one Canadian province, via 148 tributaries, 38 of which are major rivers. It produces 70% of Long Island Sound's fresh water, discharging at per second.
Royal Gorge Bridge
The Royal Gorge Bridge is a tourist attraction near Cañon City, Colorado within "Royal Gorge Bridge & Park", a 360-acre (150 ha) amusement park located along the edge of the Royal Gorge around both ends of the bridge. The bridge crosses the gorge 955 feet (291 m) above the Arkansas River and held the record of highest bridge in the world from 1929 until 2001 when it was surpassed by the Liuguanghe Bridge in China. The Royal Gorge Bridge maintained the title of the world's highest "suspension" bridge until the Beipan River Guanxing Highway Bridge was completed in 2003, also in China. The bridge remains the highest bridge in the United States and was among the ten highest bridges in the world until 2012.
American River
The Silver Fork American River is a tributary of the South Fork American River, that has its origin at Silver Fork Lake
Zachary Taylor Parkway
The John James Audubon Bridge (Mississippi River), completed and opened in 2011, is a Mississippi River crossing between Pointe Coupee and West Feliciana parishes in south central Louisiana. The bridge has the second longest cable-stayed span in the Western Hemisphere (after Mexico's Baluarte bridge, though its total length is four times that of the Mexican bridge)[2]and replaces the ferry between the communities of New Roads and St. Francisville. The bridge also serves as the only bridge structure on the Mississippi River between Natchez, Mississippi and Baton Rouge, Louisiana (approximately 90 river miles). The bridge allows the Zachary Taylor Parkway to span the Mississippi.
The Audubon Bridge corridor includes:
Gualala River
The river has three forks: the South Fork, Wheatfield Fork and the North Fork. The South Fork is the longest and travels northwest, parallel to the coast along the San Andreas Fault rift zone. The Wheatfield Fork begins west of Lake Sonoma and has the largest flow of the three forks. Its tributaries include Tombs, Wolf, House, Haupt and Fuller creeks. Wheatfield is the first fork to combine with the South Fork. Buckeye Creek, a tributary of the river, joins the South Fork next. It is followed by Rockpile Creek and Big Pepperwod Creek. The North Fork is the only part of the river in Mendocino County. It travels roughly southwest towards the coast along the San Andreas Fault rift zone and meets the South Fork at the border between the counties, a few miles before the river flows into the ocean.
Concho River
The Concho River has three primary feeds: the North, Middle, and South Concho Rivers. The North Concho River is the longest fork, starting in Howard County and traveling southeast for until merging with the South and Middle forks near Goodfellow Air Force Base in San Angelo, Texas. The combined branches of the river flow east about until it eventually empties into the Colorado River within the waters of the O.H. Ivie Lake about east of Paint Rock, Texas.
American Falls
The American Falls is the second-largest of the three waterfalls that together are known as Niagara Falls on the Niagara River along the Canada–U.S. border. Unlike the much larger Horseshoe Falls, of which two-thirds is in Ontario, Canada and one-third in the U.S. state of New York, the American Falls is entirely within the United States.
Paria River
The Paria is one of the most popular destinations for canyoneering in the region. Buckskin Gulch, a side canyon along the river in the narrows section, is considered to be one of the longest and deepest slot canyons in the United States. The Paria is also home to a number of important historical, geological and biological resources. Lee's Ferry and the adjoining settlement are located within the canyon just upstream of the confluence with the Colorado River, with a number of other abandoned settlements further north. The Paria and several nearby rivers and canyons also are the site of several well-preserved specimens of Native American petroglyphs, prehistoric drawings and symbols carved into stone. The Paria boasts a vibrant desert riparian habitat that is home to a number of sensitive and endangered species, and is also the location of Wrather Arch, the longest natural arch outside of Utah (although this claim may be superseded by Aloba Arch).
About a mile south of the river and the ghost town of Pahreah is the Paria Movie Set which was the site for a number of western movies. Among the movies filmed at this site and the surrounding area were "The Outlaw Josey Wales" (1976), "Sergeants 3" (1962), "Westward the Women" (1951), and "Buffalo Bill" (1944). The old film set in the canyon was a popular attraction but was damaged in a flash flood in 1998. The buildings were dismantled and rebuilt in a nearby location by volunteers. In 2006 these new buildings were destroyed in a suspicious fire.
Kings River (California)
During the first half of the 20th century, the Kings River was the focus of a political fight over Los Angeles' proposal to dam the Middle and South Forks for power generation. Local farmers feared the city's real intention was to divert Kings water south, as it had gained notoriety for doing in the Owens Valley water wars. The KRCD, however, also wanted to dam these rivers for irrigation, and thus the proposed dam sites were excluded from Kings Canyon National Park as designated in 1940. It was not until 1965 when these areas were finally added to the park, ending a debate which had lasted more than sixty years. Today, the fall from the head of the South Fork to Pine Flat Reservoir remains the longest undammed drop of any U.S. river.
American Fork High School
American Fork High School is a public high school in American Fork, Utah, United States. Its mascot is the Caveman, chosen as a tribute to Timpanogos Cave. The school is perhaps best known for its award-winning marching band and cross country team. The band has regularly reached regional finals and national finals once, performed in high-profile parades, and been the state champion for over 20 years. The boys cross country team has consistently dominated in Utah and throughout the nation since their first state championship in 2009. American Fork High school is one of the oldest high schools in Utah. In 2017 they became one of the first schools to participate in the 6A division.
Knight's Ferry Bridge
The Knight's Ferry Bridge, spanning the Stanislaus River at Knights Ferry, California, is the longest covered bridge in the United States. It was designated a U.S. National Historic Landmark in 2012.
It was for a long time known as the longest covered bridge west of the Mississippi, and since the 2011 destruction of Old Blenheim Bridge in New York State, which had approximately the same length, is undisputed as the longest in the U.S.
South Fork Trinity River
The river and its tributaries drain in Humboldt County in the south and Trinity County in the north, comprising 34 percent of the Trinity River watershed. The Hayfork Creek sub-watershed contains , or 38 percent of the entire South Fork Trinity watershed. Most of the watershed lies on public lands (79 percent), while for Hayfork Creek, 78 percent of its watershed lies on public lands. With the Yolla Bolly Mountains in the south and the Klamath Mountains in the north, the topography of the South Fork Trinity's watershed is dissected by deep gorges and valleys separated by narrow ridges. The South Fork is the longest undammed National Wild and Scenic River in California. (The Eel River, also a Wild and Scenic River, is over twice as long, but is dammed near its headwaters. The Smith River drains a greater area but is much shorter.)
Hood Canal Bridge
The Hood Canal Bridge (officially William A. Bugge Bridge) is a floating bridge in the northwest United States, located in western Washington. It carries State Route 104 across Hood Canal of Puget Sound and connects the Olympic and Kitsap Peninsulas. At in length (floating portion ), it is the longest floating bridge in the world located in a saltwater tidal basin, and the third longest floating bridge overall. First opened in 1961, it was the second concrete floating bridge constructed in Washington. Since that time, it has become a vital link for local residents, freight haulers, commuters, and recreational travelers. The convenience it provides has had a major impact on economic development, especially in eastern Jefferson County.
California Aqueduct
When it was open, the California Aqueduct Bikeway was the longest of the paved paths in the Los Angeles area, at long from Quail Lake near Gorman through the desert to Silverwood Lake in the San Bernardino Mountains. This path was closed in 1988 due to bicyclist safety and liability issues. It is expected to remain closed indefinitely due to the continued liability issues and an increased focus on security, especially after the September 11, 2001 attacks.
Two major river systems drain and define the two parts of the Central Valley. Their impact on the California Aqueduct is both direct and indirect. The Sacramento River, along with its tributaries the Feather River and American River, flows southwards through the Sacramento Valley for about . In the San Joaquin Valley, the San Joaquin River flows roughly northwest for , picking up tributaries such as the Merced River, Tuolumne River, Stanislaus River and Mokelumne River.
Kansas River
The Kansas drains of land in Kansas (almost all of the northern half), along with in Nebraska and in Colorado, making a total of just over . When including the Republican River and its headwater tributaries, the Kansas River system has a length of , making it the 21st longest river system in the United States. Its highest headwaters are at about and extend nearly to Limon, Colorado. Much of the drainage of the river lies within the Great Plains, but the river itself exists entirely within the Mid Continent Region. The majority of the rest of the state is drained by the Arkansas (and its tributaries, the Neosho, Cimarron, and Verdigris, all three of which drain into the Arkansas in Oklahoma). A portion of central-eastern Kansas is drained by the Marais des Cygnes River, which flows into Missouri to meet the Missouri River. A small area in the extreme northeast part of the state drains directly into the Missouri. In the Kansas City metro area, some streams drain east into the Blue River tributary of the Missouri.
Missouri River
The Missouri's headwaters above Three Forks extend much farther upstream than the main stem. Measured to the farthest source at Brower's Spring, the Jefferson River is long. Thus measured to its highest headwaters, the Missouri River stretches for . When combined with the lower Mississippi, the Missouri and its headwaters form part of the fourth-longest river system in the world, at .
American River
The American River (Río de los Americanos during the period before 1847 ruled by Mexico) is a 120-mile-long river in California that runs from the Sierra Nevada mountain range to its confluence with the Sacramento River in the Sacramento Valley. Via the Sacramento River, it is part of the San Francisco Bay watershed. This river is fed by the melting snowpack of the Sierra Nevada and its many headwaters and tributaries, including the North Fork American River, the Middle Fork American River, and the South Fork American River.
Middle Fork American River
The Middle Fork American River is one of the three main branches of the American River in Northern California. The river flows from its headwaters in the Sierra Nevada, in a generally southwest direction, to join the North Fork American River near Auburn.
American River (Washington)
From its source at American Lake, it flows north for several miles, picking up its tributary the Rainier Fork American River, which flows east down from the vicinity of Chinook Pass. State Route 410 crossing Chinook Pass from Mount Rainier National Park, then follows the Rainier Fork and the American River valleys.
Buckskin Gulch
The Buckskin Gulch, a canyon in southern Utah, is one of the main tributaries of the Paria River, which is itself a minor tributary of the Colorado River. It is the longest and deepest slot canyon in the southwest United States and may be the longest in the world. As such it is one of the premier destinations for slot canyon hikers, and receives a high amount of foot traffic.
Maumelle, Arkansas
The Big Dam Bridge, the second-longest pedestrian bridge in the United States, is located three miles east of Maumelle along Highway 100 (Maumelle Boulevard). The bridge was designed by the United States Army Corps of Engineers and rises above the Arkansas River and Murray Lock and Dam. It is the longest pedestrian bridge in North America originally designed and built for that purpose. Pulaski County Judge "Buddy" Villines formally opened the bridge to the public on September 30, 2006.
Echo Bridge
Echo Bridge is a historic masonry bridge spanning the Charles River between Needham to Newton Upper Falls, Massachusetts, and Ellis Street in Newton. The bridge carries the Sudbury Aqueduct and foot traffic, and is located in the Hemlock Gorge Reservation. At the time of its construction in 1875–1877 it was the second longest masonry arch in the country. It was listed on the National Register of Historic Places in 1980, and was named an American Water Landmark in 1981.
American River
The North Fork and its tributaries provides one of the most biologically diverse habitats in North America. The North Fork features scenic multi-use trails along forested ridgetops and riparian corridors. It flows freely as a designated National Wild and Scenic Rivers System river until reaching the North Fork Dam, which was built to contain mining debris. This dam creates the small Lake Clementine just north of the Foresthill Bridge and upstream of the confluence with the Middle Fork American River at Auburn. Below the confluence, the North Fork continues several miles until reaching Folsom Lake. Both the North Fork and Middle Fork feature archaeological and historic sites of ancient Native American culture and 1850s Gold Rush habitation.
Buffalo River (Tennessee)
The Buffalo River is the longest unimpounded river in Middle Tennessee in the United States, flowing through the southern and western portions of that region. It is the largest tributary of the Duck River and is used for canoeing, especially in its middle section. The river is named for the Buffalo fish which was abundant when the first European settlers arrived.
Locust Fork of the Black Warrior River
The Locust Fork River, in Alabama, USA, is one of three major tributaries of the Black Warrior River, stretching across Blount, and some portions of Etowah, Jefferson and Marshall counties. Its 158-mile course drains a watershed of 1,209 square miles and comprises challenging whitewater rapids popular with canoers and kayakers, as well as smooth water sections for tubing, and spots for sport fishing. Anglers hail some of those spots as among the best sport fishing in AL.
In the late 1980s, the Birmingham Water Works proposed damming the river as a source of drinking water. When those plans became public, the grass-roots Friends of the Locust Fork River formed to investigate. The group held public meetings and suggested better sources of water for the metropolis. Plans for the dam were finally suspended.
Black Fork (Cheat River tributary)
The Black Fork is a principal tributary of the Cheat River in the Allegheny Mountains of eastern West Virginia, USA. It is a short stream, about four miles (6 km) in length, formed by the confluence of two other streams not far above its mouth. It was traditionally considered one of the five Forks of Cheat.
Colville River (Alaska)
The Colville River (Inupiat: "Kuukpik") is a major river of the Arctic Ocean coast of Alaska in the United States, approximately long. One of the northernmost major rivers in North America, it drains a remote area of tundra on the north side of the Brooks Range entirely above the Arctic Circle. The river is frozen for more than half the year and floods each spring.
Frisco Bridge
Construction for the Kansas City, Fort Scott and Memphis Railway, later acquired by the "Frisco," began in 1888 and was completed May 12, 1892. In the end the project created a bridge that was the farthest south on the Mississippi River, featured the longest truss span in the United States and cost nearly 3 million dollars.
Granite, Colorado
Granite is located midway between Leadville to the north, and Buena Vista to the south. The Arkansas River, which once saw extensive placer mining during the Colorado Gold Rush, runs through Granite. It is the sixth longest river in the US; the headwater is 17 miles north in the Leadville area. Granite is located between two mountain ranges: Mosquito Range to the east and the Sawatch Range to the west, and it is within approximately 10 miles of two of the highest peaks in the contiguous United States. To the northwest lies Mount Elbert, the highest of the fourteeners in the Sawatch Range and second highest peak in the contiguous United States. Neighboring Mount Massive is the third highest peak. Nearby Independence Pass, at 12,100 feet (3,687 m), is the highest paved crossing of the Continental Divide in the United States. The elevation, 9,012 ft (2,747 m), brings cool summers and cold winters to the area. Winter temperatures frequently drop to -25 and -30 (USDA zone 4). Surrounded by moisture-robbing mountains, the climate is semiarid, though deep winter snows are common.
The Pike's Peak Gold Rush that began in 1859 brought an unprecedented number of people into the Colorado Territory. Among the earliest gold discoveries in Colorado were placer deposits near the headwaters of the Arkansas River in Oro city. In 1860, Cache Creek, a mining camp near Granite, became the first settlement of note with a population of about 300. By the following year, Granite, located on either side of the Arkansas river, exploded to a population of 3,000. The settlement included a three-mile stretch of river and extended two-miles up Cache Creek. In 1867 free quartz gold was discovered and a mill was built. In 1868 the county seat was moved to Granite from the neighboring town of Dayton near present-day Twin Lakes, no longer in existence.
Au Sable River Canoe Marathon
The Au Sable River Canoe Marathon, presented by Consumers Energy, (also stylized as the AuSable River Canoe Marathon) is an annual canoe race in Michigan from Grayling to Oscoda. Nicknamed and known simply as "The Marathon," it first ran in 1947, and is perhaps the oldest marathon canoe race in the United States, and is the longest, non-stop, canoe-only race in North America. The race has been billed as "The World's Toughest Spectator Race" as many of the spectators follow the racers overnight down the full to the finish.
Since 1971, the race has been held during the last full weekend in July, during Grayling's annual Au Sable River Festival. To determine the starting position of the racers for the night of the Canoe Marathon, there is a sprint held to determine which of the teams is fastest or slowest. The sprint trials are held at Penrod's canoe livery. The trials are held the Wednesday, Thursday, and Friday before the race on Saturday. Each team will head upstream one quarter mile towards the Old AuSable Fly Shop. Once there you must complete a counter clockwise turn around a buoy. Then you must head back downstream to the starting point and the next team does not start until the team finishing reaches a point close to the start buoy. On average this can take from 2 minutes and 15 seconds to 5 minutes. The overall finish times range from about 4 minutes and 30 seconds to 13 minutes. While they are on their way back to the starting buoy they must maintain the number of buoys on the left side of their canoe. Once all of the teams have finished the sprint trials they will be lined up in groups of five, from fastest to slowest, on the night of the Marathon, to make the LeMans-style foot race that starts the race.
John Day River
The John Day River is a tributary of the Columbia River, approximately long, in northeastern Oregon in the United States. Undammed along its entire length, the river is the third longest free-flowing river in the contiguous United States. There is extensive use of its waters for irrigation. Its course furnishes habitat for diverse species, including wild steelhead and Chinook salmon runs. However, the steelhead populations are under federal Endangered Species Act (ESA) protections, and the Chinook salmon have been proposed for such protection.
Columbia, Tennessee
Columbia is located at (35.615022, −87.044464). It is nestled along the banks of the Duck River at the southern edge of the Nashville Basin with the higher elevated ridges of the Highland Rim located to the south and west of the city. The Duck River is the longest river located entirely within the state of Tennessee. Free flowing for most of its length, the Duck River is home to over 50 species of freshwater mussels and 151 species of fish, making it the most biologically diverse river in North America. It enters the city of Manchester and meets its confluence with a major tributary, The Little Duck River, at Old Stone Fort State Park, named after an ancient Native American structure between the two rivers believed to be nearly 2,000 years old. The Duck River is sacred to most of the founding Native American tribes east of the Mississippi River.
International Selkirk Loop
The International Selkirk Loop is a scenic highway in the U.S. states of Idaho and Washington, as well as the Canadian province of British Columbia. The loop encircles the Selkirk Mountain Range, and offers several side trips aside from the main route. Included on the loop is the Kootenay Lake Ferry, the longest free ferry in the world. The portion of the loop in the United States has been designated an All-American Road by the United States Department of Transportation.
Hayfork Creek
Hayfork Creek is a tributary of the South Fork Trinity River in Northern California in the United States. At over long, it is the river's longest tributary and is one of the southernmost streams in the Klamath Basin. It winds through a generally steep and narrow course north then west through the forested Klamath Mountains, but also passes through the Hayfork and Hyampom Valleys, which comprise the primary agricultural regions of Trinity County.
American River
The American River is specifically known for its whitewater rafting. The South Fork has Class III rapids, the Middle Fork has Class IV rapids, and the North Fork has Class IV spring run-off rapids. All three rivers also feature Class II sections. The areas with rapids still feature beautiful scenic views and wildlife, which is what makes it the most popular whitewater rafting location in California
South Fork Spring River
The South Fork Spring River (commonly South Fork of the Spring River or simply South Fork River) is a tributary of the Spring River, roughly long, in southern Missouri and northern Arkansas in the United States. The river flows through the Salem Plateau of the Ozarks and it is part of the Spring River Tributaries Watershed.
Snake River
The Snake River is the thirteenth longest river in the United States. Its watershed is the 10th largest among North American rivers, and covers almost in portions of six U.S. states: Wyoming, Idaho, Nevada, Utah, Oregon, and Washington, with the largest portion in Idaho. Most of the Snake River watershed lies between the Rocky Mountains on the east and the Columbia Plateau on the northwest. The largest tributary of the Columbia River, the Snake River watershed makes up about 41% of the entire Columbia River Basin. Its average discharge at the mouth constitutes 31% of the Columbia's flow at that point. Above the confluence, the Snake is slightly longer than the Columbia— compared to —and its drainage basin is slightly larger—4% bigger than the upstream Columbia River watershed.
Black Fork Mohican River
The Black Fork is a principal tributary of the Mohican River, 58.4 miles (94 km) long, in north-central Ohio in the United States. Via the Mohican, Walhonding, Muskingum and Ohio Rivers, it is part of the watershed of the Mississippi River, draining an area of 351 square miles (909 km²). According to the Geographic Names Information System, it has also been known historically as "Armstrongs Creek" and "Black Fork Creek."
South Fork Clearwater River
The river is formed by the confluence of the American River and Red River in the Nez Perce National Forest at an elevation of . The roughly American River rises at and flows generally south to the confluence, while the northwest flowing Red River, rising at , is about long. The American River is sometimes considered part of the main stem. From the confluence the South Fork flows west through a canyon followed by Idaho State Highway 14, receiving the Crooked River from the left and Newsome Creek from the right before reaching Golden, where it receives Tenmile Creek from the left. Further west the river receives Johns Creek from the left, Meadow Creek from the right and Mill Creek from the left, and the gorge deepens to a maximum of some as the river swings north near Grangeville. From there the river flows generally north, past Harpster and Stites, before reaching its mouth on the Clearwater at Kooskia, at an elevation of .
American River 50 Mile Endurance Run
The American River 50 Mile Endurance Run, or AR50, is a 50-mile (80.47 kilometer) ultramarathon beginning in Sacramento, California and ending in Auburn, California. The event is held annually in April.
Fort River
The Fort River has a wide variety of wildlife due to it being the longest free-flowing tributary (having no dams or other man made changes made to the rivers shape or flow) of the Connecticut River. Because of this there is a lot of wildlife making it one of the 3 most diverse rivers in the state. Mussels, Eastern Pearlfish, Sea Lampreys, and American Eel's.
Appalachia
The effort to connect Appalachia with the outside world has required numerous civil engineering feats. Millions of tons of rock were removed to build road segments such as Interstate 40 through the Pigeon River Gorge at the Tennessee-North Carolina state line and U.S. Route 23 in Letcher County, Kentucky. Large tunnels were built through mountain slopes at Cumberland Gap to speed up travel along U.S. Route 25E. The New River Gorge Bridge in West Virginia, completed in 1977, was the longest and is now the fourth-longest single-arch bridge in the world. The Blue Ridge Parkway's Linn Cove Viaduct, the construction of which required the assembly of 153 pre-cast segments up the slopes of Grandfather Mountain, has been designated a historic civil engineering landmark.
Wolastoq
The Wolastoq (; ) is a river flowing approximately from headwaters in the Notre Dame Mountains near the Maine-Quebec border through New Brunswick to the northwest shore of the Bay of Fundy. The river and its tributary drainage basin formed the territory of the Wolastoqiyik and Passamaquoddy First Nations prior to European colonization. As the longest river between Chesapeake Bay and the Gulf of Saint Lawrence the Saint John offered one of the best transportation corridors for First Nations refugees to retreat from the English colonization of North America's Atlantic coast. The Wolastoqiyik and their Acadian allies retreated upstream after English victories in the French and Indian War to establish the Republic of Madawaska on the remote upper river. Inhabitants of the upper river rejected both Canadian and United States sovereignty until the present international boundary was established by the Webster-Ashburton Treaty of 1842. The lower river has been developed for agriculture and industry, while the United States portion of the river upstream of Madawaska remains the sparsely populated North Maine Woods. The historic isolation of Madawaska has helped preserve the Acadian French dialect.
Amazon River
The Amazon River (, ; Spanish and ) in South America is the largest river by discharge volume of water in the world, and by some definitions it is the longest.
The headwaters of the Apurímac River on Nevado Mismi had been considered for nearly a century as the Amazon's most distant source, until a 2014 study found it to be the Cordillera Rumi Cruz at the headwaters of the Mantaro River in Peru. The Mantaro and Apurímac join, and with other tributaries form the Ucayali River, which in turn meets the Marañón River upstream of Iquitos, Peru, to form what countries other than Brazil consider to be the main stem of the Amazon. Brazilians call this section the Solimões River above its confluence with the Rio Negro to form what Brazilians call the Amazon at the Meeting of Waters () at Manaus, the river's largest city.
Alex Fraser Bridge
The Alex Fraser Bridge (also known as the Annacis Bridge) is a cable-stayed bridge over the Fraser River that connects Richmond and New Westminster with North Delta in Greater Vancouver, British Columbia. The bridge is named for Alex Fraser (1916 – 1989), a former British Columbia Minister of Transportation.
The bridge was the longest cable-stayed bridge in the world when it opened on September 22, 1986 and was the longest in North America until the Arthur Ravenel Jr. Bridge opened in 2005. As of 2009 it is the 32nd-longest cable-stayed bridge in the world, and second-longest in North America. It is long with a main span of . The towers are tall. It consists of six lanes, three in each direction, and has a maximum speed limit of 90 km per hour. Upon opening in 1986, only four of the six available lanes were open. Cyclists and pedestrians share two narrow side-walks one on each side. All six lanes opened in 1987 after traffic demand justified the need.
South Fork Kings River
The South Fork is the largest headwater of the Kings River. It originates at an elevation of at an unnamed lake in Kings Canyon National Park, south of Mather Pass and west of Split Mountain, in a high alpine basin known as Upper Basin. It flows south, and is paralleled for several miles by the combined Pacific Crest Trail/John Muir Trail. The trail and river separate at a point west of Taboose Pass, where the river turns to the southwest through a deep gorge between Cirque Crest to the northwest and Arrow Ridge to the southeast. To the east, the Muro Blanco cliffs rise more than half a mile (0.8 km) above the river.
American Fork
American Fork may refer to:
Shavers Fork
Shavers Fork of the Cheat River is situated in the Allegheny Mountains of eastern West Virginia, USA. It is 88.5 mi (142.5 km) long and forms the Cheat at its confluence with Black Fork at Parsons. It was traditionally considered one of the five Forks of Cheat and its upper reaches constitute the highest river in the eastern United States.
American River
Although miners looking for gold worked all three forks of the American River, the South Fork held the richest deposits. However, as the easily accessible placer gold was played out, large companies used hydraulic mining to access gold buried deeper in the soil. Unfortunately, this large and extensive mining practice washed away entire mountainsides and heavily polluted all the waterways, including the American River.
Extradosed bridge
The Golden Ears Bridge, crosses the Fraser River between the municipalities of Pitt Meadows / Maple Ridge and Langley. It is the longest extradosed bridge in North America. The bridge opened to traffic on June 16, 2009.
American River
The American River headwaters lie along about along the Sierra Crest from Mount Lincoln in the north () where it adjoins the watersheds of the South Yuba and Truckee Rivers, to Winnemucca Lake in the Mokelumne Wilderness, where it meets the watersheds of the Mokelumne and Carson Rivers. Lands east of the American River watershed divide drain into Lake Tahoe, which flows into the Truckee River. During most years, a significant snowpack builds up in the Sierra Nevada which provides water during the hot, dry summers. In warmer winters much of the precipitation may fall as rain instead, causing flooding, but resulting in lower summer flows due to the lack of snow. Due to California's highly variable weather patterns, runoff volumes in the American River can rise and fall drastically from one year to the next.
South Fork American River
The South Fork of the American has approximately eight sections of boatable whitewater ranging from class II to class V. The most commonly run section of river is the class III stretch between Chili Bar Dam and Folsom Lake.
Delaware Canal State Park
The Delaware River is the longest free-flowing river east of the Mississippi River in the United States. It serves as a major migration path for American Shad and waterfowl. A visitor's center is located at New Hope and the park management office is located in Upper Black Eddy. Within the park are two designated natural areas: Nockamixon Cliffs and River Islands. Recreational opportunities include hiking, biking and cross-country skiing along the towpath, fishing in the canal and river, and canal boat rides.
South Fork American River
The South Fork drains an area of , or about a third of the American River watershed. Major tributaries include Silver Creek, Rock Creek, Weber Creek, and Silver Fork American River. Most of the watershed consists of high, forested mountains and steep-sided valleys that receive up to of annual precipitation, except for the westernmost section which consists of drier foothill country. The river also contributes about a third of the total outflow of the American River system.
U.S. Route 101 in Washington
US 101 enters Washington from Oregon on the Astoria–Megler Bridge, a bridge that carries vehicles across the Columbia River near its mouth; it is the longest continuous truss bridge in North America and among the longest of its kind in the world. At the north end of the bridge is an intersection with State Route 401 (SR 401), where US 101 turns west to follow the north bank of the river, forming part of the Lewis and Clark Trail Scenic Byway. The highway passes under Fort Columbia State Park in a tunnel and continues along the Willapa Hills through Chinook towards Baker Bay. At the head of the bay, near Port of Ilwaco Airport, US 101 intersects a short alternate route that bypasses the coastal section of the highway. US 101 then dives southwesterly along the Wallacut River into Ilwaco, where it runs through town as Spruce Street before turning north onto 1st Avenue after an intersection with SR 100.
James Fork
The James Fork is a river in the U.S. states of Arkansas and Oklahoma, forming on the north slope of Poteau Mountain in the Ouachita National Forest in Arkansas and flowing north and west into the Poteau River near Panama, Oklahoma. Via the Poteau and Arkansas rivers, the James Fork is part of the Mississippi River watershed.
American River
Eight hydroelectric plants on the South Fork are operated by Sacramento Municipal Utility District (SMUD) as the Upper American River Project. These plants are fed by a series of reservoirs including Loon Lake, Ice House Reservoir and Union Valley Reservoir. With the exception of Folsom Lake, Union Valley is the largest in the American River watershed, storing of water. The Upper American River Project produces 1.8 billion kilowatt hours in an average year, enough for about 20 percent of Sacramento's electricity needs. The SMUD plants are run on a peaking basis, although recreational boating and environmental flow requirements constrain their operation slightly.
Mississippi River System
The Arkansas River is one of the major tributaries in the Mississippi River system. It flows west to east starting in Colorado and dumping the Mississippi River. Its length of 1,469 miles allows it to flow through Colorado, Kansas, Oklahoma, and Arkansas. It is the sixth longest river in the US, the second longest tributary to the Mississippi River System, and the 45th longest river in the world.
American Fork Canyon
American Fork Canyon is a canyon in the Wasatch Mountains of Utah, United States. The canyon is famous for the Timpanogos Cave National Monument, which resides on its south side. It is named after the American Fork River which runs through the bottom of the canyon.
Manchac Swamp Bridge
The Manchac Swamp Bridge is a twin concrete trestle bridge in the U.S. state of Louisiana. With a total length of it is one of the longest bridges in the world over water. It is the longest bridge on the interstate system. Some claim it is the longest toll-free road bridge in the world. The bridge carries Interstate 55 and U.S. Route 51 over the Manchac Swamp in Louisiana, and represents one-third of the highway's approximately 66 miles in Louisiana. Opening in 1979, its piles were driven beneath the swamp and with the cost of the span being $7 million per mile to complete.
South Fork American River
Meandering through the Sierra foothills this 20 mile section of river has a lot to offer. Thanks to the efforts of local communities and advocacy groups the riperean eco-system of the South Fork remains despite the destructive effects of the gold rush and other developments. The river is home to a wide array of flora and fauna such as bald eagles, golden eagles, beaver and river otter. In Spring the hillsides of the upper Chili Bar section are adorned with stunning California poppies and other wild flowers. There are also interesting historical sights on the river such as grinding holes made by the Nisenan people that once inhabited the area and diversion channels blasted out during the gold rush.
Susitna River Bridge
The Susitna River Bridge, also known as the Gold Creek Bridge, was the longest bridge span on the United States Government Railway in Alaska. The steel 504-ft. through-truss channel spans the Susitna River. It was completed in February, 1921. The crossing of the Susitna includes two 121-ft. combination Howe•truss flanking spans and two 70-ft. combination pony Howe-truss end spans, with 392 ft. of trestle at the southern approach and 28 ft. at the northern approach, making a total length of 1,322 ft. It is located 150 miles north of Anchorage, and 264 miles north of the terminus at Seward. The bridge was listed on the National Register of Historic Places in 1977.
Greenville Bridge
The Greenville Bridge is a cable-stayed bridge over the Mississippi River, in the United States, carrying US 82 and US 278 between Refuge, Mississippi, and Shives, Arkansas. When it opened in 2010, it was the fourth-longest cable-stayed bridge in North America.
Edisto River
The Edisto River is one of the longest free-flowing blackwater rivers in North America, flowing over 250 meandering miles from its sources in Saluda and Edgefield counties, to its Atlantic Ocean mouth at Edisto Beach, South Carolina. It rises in two main tributaries (North Fork & South Fork) from springs under the Sandhills region of West Central South Carolina, just to the south of the Piedmont Fall Line. It is the longest and largest river system completely contained by the borders of South Carolina. Its name comes from the Edisto subtribe of the Cusabo Indians.
Tributary
In the United States, where tributaries sometimes have the same name as the river into which they feed, they are called forks. These are typically designated by compass direction. For example, the American River receives flow from its North, Middle, and South forks. The Chicago River's North Branch has the East, West, and Middle Fork; the South Branch has its South Fork, and used to have a West Fork as well (now filled in).
Fort Peck Dam
The Fort Peck Dam is the highest of six major dams along the Missouri River, located in northeast Montana in the United States, near Glasgow, and adjacent to the community of Fort Peck. At in length and over in height, it is the largest hydraulically filled dam in the United States, and creates Fort Peck Lake, the fifth largest man-made lake in the U.S., more than long, deep, and it has a shoreline which is longer than the state of California's coastline. It lies within the Charles M. Russell National Wildlife Refuge. The dam and the lake are owned and operated by the U.S. Army Corps of Engineers and exist for the purposes of hydroelectric power generation, flood control, and water quality management.
