Conemaugh Dam (also known as Conemaugh River Dam or Conemaugh River Lake Dam) is a concrete gravity dam across the Conemaugh River, near the town of Saltsburg, in Pennsylvania. The dam was authorized by the Flood Control Act of 1936 and completed in 1952 by the U.S. Army Corps of Engineers for flood protection on the Conemaugh, Kiskiminetas, and Allegheny Rivers. The dam is one of 16 flood control structures in the Corps' Pittsburgh District. [2]
With a capacity of 355,000 acre-feet (438,000 dam3), the lake is usually kept at a much lower level of 5,140 acre-feet (6,340 dam3), to accommodate flash floods. [1] Water is released as quickly as possible while not exacerbating flooding conditions downstream. The dam has prevented a total of $2.2 billion of flooding-related damages between 1952 and 2013, including $375 million during 2004's Hurricane Ivan alone. [2] The dam also supplies water to a 14 MW hydroelectric power station which was commissioned in 1989. [3]
Conemaugh Lake Recreation Area is located adjacent to the dam and preserves several historic sites, including segments of the Main Line Canal that once connected Pittsburgh to Philadelphia. [4] [5]
Hugh Keenleyside Dam is a flood control dam spanning the Columbia River, 12 km upstream of the city of Castlegar, British Columbia, Canada.
Watts Bar Dam is a hydroelectric dam on the Tennessee River in Meigs and Rhea counties in Tennessee, United States. The dam is one of nine dams on the main Tennessee River channel operated by the Tennessee Valley Authority, which built the dam in the early 1940s to provide flood control and electricity and to help create a continuous navigable channel along the entire length of the river. The dam is the technical boundary between the 39,090-acre (15,820 ha) Watts Bar Lake— which it impounds— and Chickamauga Lake, which stretches from the dam's tailwaters southward to Chattanooga.
Jennings Randolph Lake is a reservoir of 952 acres (3.85 km2) located on the North Branch Potomac River in Garrett County, Maryland and Mineral County, West Virginia. It is approximately 8 miles (13 km) upstream of Bloomington, Maryland, and approximately 5 miles (8.0 km) north of Elk Garden, West Virginia.
Friant Dam is a concrete gravity dam on the San Joaquin River in central California in the United States, on the boundary of Fresno and Madera Counties. It was built between 1937 and 1942 as part of a U.S. Bureau of Reclamation (USBR) water project to provide irrigation water to the southern San Joaquin Valley. The dam impounds Millerton Lake, a 4,900-acre (2,000 ha) reservoir about 15 miles (24 km) north of Fresno.
Castaic Dam is an embankment dam in northwestern Los Angeles County, California, in the unincorporated area of Castaic. Although located on Castaic Creek, a major tributary of the Santa Clara River, Castaic Creek provides little of its water. The lake is the terminus of the West Branch of the California Aqueduct, part of the State Water Project. The dam was built by the California Department of Water Resources and construction was completed in 1973. The lake has a capacity of 325,000 acre-feet (401,000,000 m3) and stores drinking water for the western portion of the Greater Los Angeles Area.
Guntersville Dam is a hydroelectric dam on the Tennessee River in Marshall County, in the U.S. state of Alabama. It is one of nine dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the late 1930s as part of a New Deal era initiative to create a continuous navigation channel on the entire length of the river and bring flood control and economic development to the region. The dam impounds the Guntersville Lake of 67,900 acres (27,500 ha), and its tailwaters feed into Wheeler Lake.
Douglas Dam is a hydroelectric dam on the French Broad River in Sevier County, Tennessee, in the southeastern United States. The dam is operated by the Tennessee Valley Authority (TVA), which built the dam in record time in the early 1940s to meet emergency energy demands at the height of World War II. Douglas Dam is a straight reinforced concrete gravity-type dam 1705 feet long and 202 feet high, impounding the 28,420-acre (11,500 ha) Douglas Lake. The dam was named for Douglas Bluff, a cliff overlooking the dam site prior to construction.
Englebright Dam is a 280 ft (85 m) high variable radius concrete arch dam on the Yuba River in the Sacramento River Basin, located in Yuba and Nevada counties of California, United States. It was put into service in 1941 by the United States Army Corps of Engineers.
The Youghiogheny River Lake is a flood control reservoir that is located in southwestern Pennsylvania and western Maryland. It is a significant tourist attraction that brings in more than one million visitors a year to the area.
Shenango River Lake is a reservoir in the Shenango River Valley of western Pennsylvania and northeastern Ohio. Authorized by the Flood Control Acts of 1938, the lake is one of 16 flood control projects in the Pittsburgh District designed to prevent flooding. It is a popular site among anglers and is lined by 330 campsites.The campground also hosts a Geodesic dome green house that is used to propagate native species and help pollinator dependent species. Shenango River lake offers a variety of outdoor activities. Such as waterfowl and birdwatching, boating, hunting, Canoeing, Kayaking, and other various water activities.
Amistad Dam is a major embankment dam across the Rio Grande between Texas, United States, and Coahuila, Mexico. Built to provide irrigation water storage, flood control, and hydropower generation, it is the largest dam along the international boundary reach of the Rio Grande. The dam is over 6 miles (9.7 km) long, lies mostly on the Mexican side of the border, and forms Amistad Reservoir. It supplies water for irrigation in the Rio Grande Valley, 574 miles (924 km) upstream of the Rio Grande's mouth on the Gulf of Mexico at Brownsville, Texas/Matamoros, Tamaulipas.
Cottonwood Springs Dam is a dam in Fall River County, South Dakota in the southwestern part of the state, south of the Black Hills.
Salamonie Dam is a dam in Wabash County, Indiana.

Abiquiu Dam is a dam on the Rio Chama, located about 60 miles (97 km) northwest of Santa Fe in Rio Arriba County, New Mexico, USA. Built and operated by the U.S. Army Corps of Engineers (USACE), the dam is an earth embankment structure 354 feet (108 m) high and 1,800 feet (550 m) long, containing 11.8 million cubic yards of fill. The dam forms Abiquiu Lake, one of the largest lakes in New Mexico, with a full storage capacity of 1,369,000 acre-feet (1,689,000 dam3) and 5,200 acres (2,100 ha) of water. To date, the reservoir has never filled to capacity, with a record high of 402,258 acre-feet (496,178 dam3), 29.4% of full pool, on June 22, 1987. The dam's primary purpose is flood control, in addition to irrigation and municipal water storage, and hydroelectric generation.
