The Roanoke River runs 410 miles (660 km) long through southern Virginia and northeastern North Carolina in the United States. A major river of the southeastern United States, it drains a largely rural area of the coastal plain from the eastern edge of the Appalachian Mountains southeast across the Piedmont to Albemarle Sound. An important river throughout the history of the United States, it was the site of early settlement in the Virginia Colony and the Carolina Colony. An 81-mile (130 km) section of its lower course in Virginia between the Leesville Lake and Kerr Lake is known as the Staunton River, pronounced, as is the Shenandoah Valley city of that name. It is impounded along much of its middle course to form a chain of reservoirs.

The San Luis Reservoir is an artificial lake on San Luis Creek in the eastern slopes of the Diablo Range of Merced County, California, approximately 12 mi (19 km) west of Los Banos on State Route 152, which crosses Pacheco Pass and runs along its north shore. It is the fifth largest reservoir in California. The reservoir stores water taken from the San Joaquin-Sacramento River Delta. Water is pumped uphill into the reservoir from the O'Neill Forebay which is fed by the California Aqueduct and is released back into the forebay to continue downstream along the aqueduct as needed for farm irrigation and other uses. Depending on water levels, the reservoir is approximately nine miles (14 km) long from north to south at its longest point, and five miles (8 km) wide. At the eastern end of the reservoir is the San Luis Dam, the fourth largest embankment dam in the United States, which allows for a total capacity of 2,041,000 acre-feet (2,518,000 dam3). Pacheco State Park lies along its western shores.
Raccoon Mountain Pumped-Storage Plant is a pumped-storage hydroelectric underground power station in Marion County, just west of Chattanooga in the U.S. state of Tennessee.

The Salina Pumped Storage Project is a 260-megawatt (350,000 hp) pumped-storage power station near Salina, Oklahoma. It is owned and operated by the Grand River Dam Authority (GRDA). Its construction was in response to growing power demands and a lack of dam sites on the Grand River. The first phase was completed in 1968 and the second in 1971. The upper reservoir for the power station is Lake W. R. Holway which was built on Saline Creek and the lower reservoir is Lake Hudson on the Grand River. During periods of lower power demand, water is pumped from Lake Hudson to Lake Holway and released back down through the pump-generators during periods of high energy demand.
Norris Lake, also known as Norris Reservoir, is a reservoir that is located in Tennessee. The lake was created by the Norris Dam at the Cove Creek Site on the Clinch River in 1936 by the Tennessee Valley Authority (TVA) for flood control, water storage, and hydroelectric power. Norris Dam and its reservoir were the first major project taken on by the TVA. The lake, the dam, and the town of Norris, Tennessee are named for George W. Norris, who was a U.S. Senator from Nebraska and who wrote the legislation that created the TVA.
