The Norfork Tailwater is the segment of the North Fork River below Norfork Dam in north central Arkansas. Near Salesville, Arkansas, the Norfork Tailwater is about 4.8 miles (7.7 km) long and stretches from the dam below Lake Norfork to the White River. The Norfork Tailwater is home to brown, rainbow, cutthroat, and brook trout, as well as other fish. A trout hatchery (the Norfork National Fish Hatchery) near Quarry Park keeps the tailwater stocked with trout, while the dam’s cold water output provides suitable habitat for these cool-water game fish.
The North Fork River or the North Fork of White River is a 109-mile-long (175 km) tributary of the White River, into which it flows near Norfork, Arkansas.
Norfork Dam is a large dam in northern Arkansas southeast of Mountain Home. It dams North Fork River and creates Norfork Lake. The top of the dam supports a 2-lane roadway, part of AR 177.
Arkansas is a state in the southern region of the United States, home to over 3 million people as of 2018. Its name is of Siouan derivation from the language of the Osage denoting their related kin, the Quapaw Indians. The state's diverse geography ranges from the mountainous regions of the Ozark and the Ouachita Mountains, which make up the U.S. Interior Highlands, to the densely forested land in the south known as the Arkansas Timberlands, to the eastern lowlands along the Mississippi River and the Arkansas Delta.
The tailwater can be accessed in a few locations. Access is free below the dam from Highway 177. There are also a few private boat ramps and other properties that can be used to access the river with permission.
Highway 177 is a north–south state highway that runs in north central Arkansas. The route runs 16.20 miles (26.07 km) from Herron north over the Norfork Dam, then south to Pineville.
On April 10, 2008, the Army Corp of Engineers opened the dam floodgates.The mass of water changed the river's depth in some places, and boaters and waders should use caution.
Norfork is a city in Baxter County, Arkansas, United States. The population was 550 at the 2010 census.
The Ozarks, also called the Ozark Mountains or Ozark Plateau, is a physiographic region in the U.S. states of Missouri, Arkansas, Oklahoma, and extreme southeastern Kansas. The Ozarks cover a significant portion of northern Arkansas and most of the southern half of Missouri, extending from Interstate 40 in Arkansas to the Interstate 70 in central Missouri.
The Arkansas River is a major tributary of the Mississippi River. It generally flows to the east and southeast as it traverses the U.S. states of Colorado, Kansas, Oklahoma, and Arkansas. The river's source basin lies in the western United States in Colorado, specifically the Arkansas River Valley, where the headwaters derive from the snowpack in the Sawatch and Mosquito mountain ranges. It then flows east into the Midwest via Kansas, and finally into the South through Oklahoma and Arkansas.
The White River is a 722-mile (1,162 km) long river that flows through the U.S. states of Arkansas and Missouri. Originating in the Boston Mountains of northwest Arkansas, it flows northwards into southern Missouri, and then turns back into Arkansas, flowing southeast to its mouth at the Mississippi River.
The Spring River is a 57-mile (92 km) long river which flows through the U.S. states of Missouri and Arkansas. It consists of two branches, the South Fork of the Spring River and the Spring River proper. The South Fork of the Spring River starts in Howell County, Missouri and flows south through Fulton and Sharp counties in Arkansas. The South Fork of the Spring River joins the Spring River proper near the town of Hardy, Arkansas. The South Fork is a quiet stream with gravelly bars that are ideal for camping.
The Little Red River is a 102-mile-long (164 km) river in White, Van Buren, Searcy, Stone and Cleburne counties of north-central Arkansas.
The rainbow trout is a trout and species of salmonid native to cold-water tributaries of the Pacific Ocean in Asia and North America. The steelhead is an anadromous (sea-run) form of the coastal rainbow trout(O. m. irideus) or Columbia River redband trout (O. m. gairdneri) that usually returns to fresh water to spawn after living two to three years in the ocean. Freshwater forms that have been introduced into the Great Lakes and migrate into tributaries to spawn are also called steelhead.
The cutthroat trout(Oncorhynchus clarkii) is a fish species of the family Salmonidae native to cold-water tributaries of the Pacific Ocean, Rocky Mountains, and Great Basin in North America. As a member of the genus Oncorhynchus, it is one of the Pacific trout, a group that includes the widely distributed rainbow trout. Cutthroat trout are popular gamefish, especially among anglers who enjoy fly fishing. The common name "cutthroat" refers to the distinctive red coloration on the underside of the lower jaw. The specific name clarkii was given to honor explorer William Clark, coleader of the Lewis and Clark Expedition.
Tailwater refers to waters located immediately downstream from a hydraulic structure, such as a dam, spillway, bridge or culvert. Generally measured and reported as the average water depth downstream of an hydraulic structure, tailwater can vary based on the outlet from the structure as well as downstream influences that may restrict or advance the usual flow of water from the structure. Failure of a dam or hydraulic structure will dramatically increase the tailwater level.
The Salmon River is a large river in Upstate New York in the United States. The river is a popular and economically important sportfishing destination, and the most heavily fished of New York's Lake Ontario tributaries. From its headwaters in the Tug Hill region of New York, it flows 44 miles (71 km) westward through two hydroelectric dams and over the 110-foot (34 m) Salmon River Falls before it empties into eastern Lake Ontario at Port Ontario in Oswego County. The Salmon River watershed drains approximately 280 square miles (730 km2).
Lake Oroville is a reservoir formed by the Oroville Dam impounding the Feather River, located in Butte County, northern California. The lake is situated 5 miles (8.0 km) northeast of the city of Oroville, within the Lake Oroville State Recreation Area, in the western foothills of the Sierra Nevada. Known as the second-largest reservoir in California, Lake Oroville is treated as a keystone facility within the California State Water Project by storing water, providing flood control, recreation, freshwater releases assist in controlling the salinity intrusion Sacramento-San Joaquin Delta and protecting fish and wildlife.
Lake Taneycomo is a man-made lake or reservoir on the White River in the Ozark Mountains of Taney County, Missouri. The reservoir is named for the county in which it is located: Taney County, MO.
Capilano River Regional Park is located in the District of North Vancouver in British Columbia, Canada. It is one of twenty-one regional parks operated by the Metro Vancouver. The park encompasses most of the upstream areas of the Capilano River below the Cleveland Dam. The area north of the dam surrounding Capilano Lake is closed to the public as it is a GVRD watershed. The privately operated Capilano Suspension Bridge crosses the river, but it is not within park boundaries and does not access the park.
The Rio Chama, a major tributary river of the Rio Grande, is located in the U.S. states of Colorado and New Mexico. The river is about 130 miles (210 km) long altogether. From its source to El Vado Dam its length is about 50 miles (80 km), from El Vado Dam to Abiquiu Dam is about 51 miles (82 km), and from Abiquiu Dam to its confluence with the Rio Grande is about 34 miles (55 km).
The Nimbus Dam is a base load hydroelectric dam on the American River near Folsom, California. Approximately 8,700 acre feet (10,700 dam3) of water is retained by the dam. It is responsible for the impoundment of water from the American River to create the Lake Natoma reservoir. The dam stands 76 feet and spans 1,093 feet. The Nimbus powerplant consists of two generators. Each generator contains enough electrical power to power over 200,000 100-watt light bulbs, about 15,500 kilowatts of electrical power. Nimbus Dam consists of 18 radial gates, each with their own gate bays. These 18 gates today are the ones that were completed in 1955 along with the rest of the dam. Of the eighteen gates, four of them have had their coating system replaced. This protects the gates from a faster rate of corrosion. The other fourteen gates have the original coating.
The Gavins Point National Fish Hatchery is a fish hatchery administered by the U.S. Fish and Wildlife Service, located approximately 4 miles west of Yankton, in Yankton County, South Dakota, United States. The hatchery is located just below Gavins Point Dam, near the Missouri River.
