Hydroelectric power plants vary in terms of the way they harvest energy. One type involves a dam and a reservoir. The water in the reservoir is available on demand to be used to generate electricity by passing through channels that connect the dam to the reservoir.
Beaver dams typically range in length from a few meters to about 100 metres (330 ft). [8] Canals can be over 0.5 kilometres (1,600 ft) long. [9] The largest known beaver dam is in Wood Buffalo National Park in Alberta, Canada, and is 775 metres (2,543 ft) long. [10]

Hydroelectric power stations continued to become larger throughout the 20th century. Hydropower was referred to as "white coal". [19] Hoover Dam's initial 1,345 MW power station was the world's largest hydroelectric power station in 1936; it was eclipsed by the 6,809 MW Grand Coulee Dam in 1942. [20]
The Edersee Dam in Hesse, Germany. 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.
The Colorado River had experienced natural flooding before the construction of the Hoover Dam. The dam eliminated the natural flooding, threatening many species adapted to the flooding, including both plants and animals. [127] The construction of the dam devastated the populations of native fish in the river downstream from the dam. [128]
Previous upstream dams and reservoirs were part of the 1980s James Bay Project. There are also small and somewhat-mobile forms of a run-of-the-river power plants. One example is the so-called electricity buoy, a small floating hydroelectric power plant. Like most buoys, it is anchored to the ground, in this case in a river.
