Until 1988, it was named Squaw Rapids Dam. The dam altered water levels in the Saskatchewan River, which made the area uninhabitable for a lot of animals. The impact on fishers and trappers was acknowledged in 1989 with a payment of 15 million dollars. The environmental impact of the dam and power station continues however. [2]
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. Hydropower is often used in conjunction with dams to generate electricity. A ...
The effect of the Itezhi-Tezhi Dam release during this season is shown in the above NASA photos. According to a NASA website, in June 2004 an agreement was made with the hydroelectricity company to restore water releases from the dams according to a more natural flooding regime, presumably by keeping to the original intention of a 300-cubic ...
The main dam wall, built of earth and rock fill, stretches 2,743 metres (8,999 ft) from the island to river right, standing 148 metres (486 ft) high. A pair of concrete auxiliary dams spans the river from the island to river left. The dam's two spillways are on the auxiliary dams rather than the main dam. The main spillway has a discharge ...
The High Dam has also improved the efficiency and the extension of the Old Aswan Hydropower stations by regulating upstream flows. [31] At the time of completion, it was the largest power station in Africa and the 6th largest hydroelectric power station in the world. All High Dam power facilities were completed ahead of schedule.
Dworshak Dam is a concrete gravity dam in the western United States, on the North Fork of the Clearwater River in north central Idaho. In Clearwater County, the dam is located approximately four miles (6 km) northwest of Orofino and impounds the Dworshak Reservoir for flood control and hydroelectricity generation. By capacity, the reservoir is ...
Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, [1] which is more than all other renewable sources combined and also more than nuclear power. [2] Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. [2]
Katse Dam reservoir and intake tower A 320 metre long WIRTH 529 tunnel boring machine used on the project Lesotho Highlands Water Project. The Lesotho Highlands Water Project (LHWP) is an ongoing water supply project with a hydropower component, developed in partnership between the governments of Lesotho and South Africa.
