A saddle dam is an auxiliary dam constructed to confine the reservoir created by a primary dam either to permit a higher water elevation and storage or to limit the extent of a reservoir for increased efficiency. An auxiliary dam is constructed in a low spot or "saddle" through which the reservoir would otherwise escape.
The fraction of storage volume in the reservoir above the spillway crest can only be used for the temporary storage of floodwater; it cannot be used as water supply storage because it sits higher than the dam can retain it. In an intermediate type, normal level regulation of the reservoir is controlled by the mechanical gates.
This dam slows a normally fast and shallow river for partial diversion to a hydroelectric dam. The diversion tunnel opening can be seen in the upper left. The Imperial Dam diverting the Colorado River in the southwestern United States. A diversion dam is a dam that diverts all or a portion of the flow of a river from its natural
A reservoir (/ ˈ r ɛ z ər v w ɑːr /; from French réservoir [ʁezɛʁvwaʁ]) is an enlarged lake behind a dam, usually built to store fresh water, often doubling for hydroelectric power generation.
Despite the large difference in installed capacity between Three Gorges Dam and Itaipu Dam, they generate nearly equal amounts of electrical energy during the course of an entire year - Itaipu 103 TWh in 2016 [1] and Three Gorges 111.8 TWh in 2020, [2] because the Three Gorges experiences six months per year when there is very little water ...
A barrage dam can be used to divert water for irrigation needs or limit the amount of water downstream. In most cases, a barrage dam is built near the mouth of the river. The site of dam construction needs to be thoroughly investigated to ensure that the foundation is strong enough to support the dam and has low possibility of failing. [2]

The largest reservoir in Tasmania is the 12,359-gigalitre (2,719 × 10 ^ 9 imp gal; 3,265 × 10 ^ 9 US gal) Lake Gordon in the South West region of the state, formed by the Gordon Dam. As of 2015 [update] , 44 per cent of all the dams in Tasmania were constructed for the purpose of generating hydro-electricity .
