The Ramganga Dam, also known as the Kalagarh Dam, is an embankment dam on the Ramganga River 30NaN0 upstream of Kalagarh in Pauri Garhwal district, Uttarakhand, India. It is located within the Jim Corbett National Park.
The dam is part of the Ramganga Multipurpose Project — an irrigation and hydroelectric project. It supports a 198 MW power station and provides water for the irrigation of 575000NaN0 of farmland. In addition, it provides for flood control and recreation. Construction on the dam began in 1961 and it was completed in 1974. The three generators in the power station were commissioned in December 1975, November 1976 and March 1977.[1]
The dam is a 1280NaN0 tall and 6300NaN0 long earth and rock-fill embankment dam with 100000000NaN0 of fill. The dam's spillway is controlled by five gates and has a maximum discharge of 84670NaN0. To support the reservoir's elevation, there is a 720NaN0 tall saddle dam on the reservoir's rim 2.50NaN0 to the northeast on the Chui Sot River. The reservoir created by both dams has a 2447000000NaN0 capacity of which 2190000000NaN0 is active (or "useful") capacity. The reservoir has a surface of 78.310NaN0 and a catchment area of 31340NaN0.[2] [3] The power station at the toe of the dam contains three 66 MW Francis turbine-generators and is afforded 84.40NaN0 of design hydraulic head.[4] Below the dam is a system of over 63000NaN0 of canals supported by three barrages and 820NaN0 of main feeder canal.[1]
