List of reservoirs by volume
As the name implies, water is held in reserve by a reservoir so it can serve a purpose.Hydroelectric power generation, on the other hand, requires many dams to build up a large volume before operation can begin.The following terms are used in connection with the volume of reservoirs: The list below largely ignores many natural lakes that have been augmented with the addition of a relatively minor dam.However, the control of water that can be held in reserve means a portion of the vast lake functions as a reservoir.For example, the Francis H. Clergue Generating Station and Saint Marys Falls Hydropower Plant, which are both on the lake's outlet, operate with just 5.9 meters total head.
