A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees are used to manage or prevent water flow into specific land regions.
Hope Mills is a town in Cumberland County, North Carolina, United States. Its population was 15,176 at the 2010 census.
Garrison Dam is an earth-fill embankment dam on the Missouri River in central North Dakota, U.S. Constructed by the U.S. Army Corps of Engineers from 1947 to 1953, at over 2 miles (3.2 km) in length, the dam is the fifth-largest earthen dam in the world. The reservoir impounded by the dam is Lake Sakakawea, which extends to Williston and the confluence with the Yellowstone River, near the Montana border.
B. Everett Jordan Lake is a reservoir in New Hope Valley, west of Cary and south of Durham in Chatham County, North Carolina, in the United States; the northernmost end of the lake extends into southwestern Durham County.
A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water.
Oroville Dam is an earthfill embankment dam on the Feather River east of the city of Oroville, California, in the Sierra Nevada foothills east of the Sacramento Valley. At 770 feet (235 m) high, it is the tallest dam in the U.S. and serves mainly for water supply, hydroelectricity generation, and flood control. The dam impounds Lake Oroville, the second-largest reservoir in California, capable of storing more than 3.5 million acre-feet (1.1×10^12 US gal; 4.3×109 m3).
The Painted Rock Dam is an earthfill embankment dam located west of Gila Bend, Arizona. It is primarily used for flood control purposes.
Table Rock Lake is an artificial lake or reservoir in the Ozarks of southwestern Missouri and northwestern Arkansas in the United States. Designed, built and operated by the U.S. Army Corps of Engineers, the lake is impounded by Table Rock Dam, which was constructed from 1954 to 1958 on the White River.
Fontana Dam is a hydroelectric dam on the Little Tennessee River in Swain and Graham counties, North Carolina, United States. The dam is operated by the Tennessee Valley Authority, which built the dam in the early 1940s to satisfy the skyrocketing electricity demands in the Tennessee Valley to support the aluminum industry at the height of World War II; it also provided electricity to a formerly rural area.
The Saluda Dam or Saluda River Dam, officially the Dreher Shoals Dam, commonly referred to as the Lake Murray Dam, is an earthen embankment dam located approximately 10 miles (15 km) west of Columbia, South Carolina on the Saluda River. Construction on the dam began in 1927 and was completed in 1930. The purpose of the dam is flood control, hydroelectricity, recreation and water supply. At the time of its completion, the Saluda Dam was the world's largest earthen dam, creating the world's largest man-made lake, Lake Murray. In 2005, construction on a 213 ft (65 m). tall roller-compacted concrete (RCC) dam was completed at the toe of the original dam in order to mitigate an earthquake-caused dam failure.
Gavins Point Dam is a 1.9 mi (3 km) long embankment rolled-earth and chalk-fill dam which spans the Missouri River and impounds Lewis and Clark Lake. The dam joins Cedar County, Nebraska with Yankton County, South Dakota a distance of 811.1 river miles (1,305 km) upstream of St. Louis, Missouri, where the river joins the Mississippi River. The dam and hydroelectric power plant were constructed as the Gavins Point Project from 1952 to 1957 by the United States Army Corps of Engineers as part of the Pick-Sloan Plan. The dam is located approximately 4 miles (6.4 km) west or upstream of Yankton, South Dakota.
Canyon Lake is a reservoir on the Guadalupe River in the Texas Hill Country in the United States. Canyon Lake is a U.S. Army Corps of Engineers reservoir formed on the Guadalupe River in Comal County by Canyon Dam, which is located about sixteen miles northwest of New Braunfels. The dam, lake, and all adjacent property are managed by the U.S. Army Corps Of Engineers. Water rights, waste water treatment, and hydroelectric generating facilities are managed by the Guadalupe-Blanco River Authority. Construction of the dam began in 1958 and was completed in 1964. The reservoir serves to provide flood control and water supply for the communities downstream from the dam. The lake is also a popular recreational destination.
Lake Needwood is a 75-acre (300,000 m2) reservoir in Derwood, Maryland, United States. Located east of Rockville, in the eastern part of Montgomery County, it is situated on Rock Creek. The lake was created by damming Rock Creek in 1965 with the goal of providing flood control and reducing soil erosion. Lake Needwood also protects the water quality of the creek by functioning as a retention basin to trap sediment from storm-water runoff.
Lake Livingston is a reservoir located in the East Texas Piney Woods. Lake Livingston was built and is owned and operated by the Trinity River Authority (TRA) of Texas under contract with the City of Houston for water-supply purposes. The USCG Auxiliary Flotilla 6-9 is also stationed on the lake. The lake is the third-largest lake located in the state of Texas. The Livingston Dam, constructed across the Trinity River about 7 miles (11 km) southwest of the city of Livingston is 2.5 miles (4 km) in length and has an average depth of 55 feet (17 m).
An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes the dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance.
Benbrook Lake is a reservoir on the Clear Fork of the Trinity River in Tarrant County, Texas, USA. The lake is located approximately 10 miles (16 km) southwest of the center of Fort Worth, where the Clear Fork and the West Fork of the Trinity River join. The lake is impounded by the Benbrook Dam. The lake and dam are owned and operated by the U.S. Army Corps of Engineers, Fort Worth District.
The Fairbairn Dam is an earth-filled embankment dam across the Nogoa River, located southwest of Emerald in Central Queensland, Australia. Constructed in 1972 for the primary purpose of irrigation, the impoundment created by the dam serves as one of the major potable water supplies for the region and assists with some flood mitigation.
Hope Mills Lake, also referred to as Hope Mills Lake #1, and by long-time citizens as The Pond, was a lake in Hope Mills in Cumberland County, North Carolina. Before it was a lake, it was a mill pond which was fed by Little Rockfish Creek. The mill pond was created in 1839 near the Hope Mills Dam for the first cotton mill in the area. At the time, the area was called Little Rockfish Village. In 2003, heavy rains caused the earthen dam to fail and the lake was unintentionally drained. By 2006, the lake had not been restored so the Friends of Hope Mills Lake was incorporated as a North Carolina non-profit organization to promote and raise funds for the timely restoration and preservation of the dam. In 2008 the new dam was completed and full for the first time in 5 years. In June 2010, the Lake was intentionally drained for safety reasons, after an inspection discovered a sinkhole that was leaking water under the dam's structure.
Delhi Dam, also known as Hartwick Dam, is an embankment dam on the Maquoketa River 2.5 kilometres (1.6 mi) southwest of Delhi, Iowa that created Lake Delhi. The dam was over-topped and subsequently failed on July 24, 2010 after a period of heavy rain. It was rebuilt in 2016.
