The natural seasonal cycle has maintained plants, fish, and animals, as they have adapted to the March–April inundation in their nutrition and breeding. Many of the local residents move their settlements annually to cope with the regular cycle of flooding. [6] The dam removes the peak of the flooding and the trough of low water in the dry season.
Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce carbon dioxide or other atmospheric pollutants and it provides a relatively ...
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.
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 Itaipu Dam opened in 1984 in South America as the largest, producing 14 GW , but was surpassed in 2008 by the Three Gorges Dam in China at 22.5 GW .
The largest hydroelectric power station is the Three Gorges Dam in China, rated at 22,500 MW in total installed capacity. After passing on 7 December 2007 the 14,000 MW mark of the Itaipu Dam , the facility was ranked as the largest power-generating facility ever built.
The Yacyretá Dam or Jasyretâ-Apipé Hydroelectric Power Station (from Guaraní jasy retã, "land of the moon") is a dam and hydroelectric power plant built over the waterfalls of Jasyretâ-Apipé in the Paraná River, between the Paraguayan City of Ayolas and the Argentine Province of Corrientes.

The main purpose of the dam is hydroelectric power production and navigation. It is the first large-scale hydroelectric project in the Brazilian Amazon rainforest. The installed capacity of the 25-unit plant is 8,370 megawatts (11,220,000 hp). Phase I construction began in 1980 and ended in 1984 while Phase II began in 1998 and ended in 2010.
