The total volume of all water held behind a dam at the maximum level possible. Initial volume Design volume The possible volume within the reservoir after it first opens. Many rivers are high in silt that over time deposits behind a dam reducing capacity. Active volume Live volume The total capacity minus the dead pool volume.
The nearly 8100 major dams in the United States in 2006. The National Inventory of Dams defines a major dam as being 50 feet (15 m) tall with a storage capacity of at least 5,000 acre-feet (6,200,000 m 3), or of any height with a storage capacity of 25,000 acre-feet (31,000,000 m 3).

If water levels continue to drop, Hoover Dam would cease generating electricity when the water level falls below 950 feet (290 m) and the lake would stabilize at a level of 895 feet (273 m) when the water reaches the lowest water outlet of the dam. [45]
Once built, the water stored behind the dam raises the water table and is then extracted with wells. A sand-storage dam is a weir built in stages across a stream or wadi. It must be strong, as floods will wash over its crest. Over time, sand accumulates in layers behind the dam, which helps store water and, most importantly, prevent evaporation ...
Nigeria's hydrological services agency has warned of potential flooding in 11 states after neighbouring Cameroon said it was starting to release water from one of its largest dams following recent ...
