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 57,500 ha (142,086 acres) 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.
The dam is a 128 m (420 ft) tall and 715 m (2,346 ft) long earth and rock-fill embankment dam with 10,000,000 m3 (13,079,506 cu yd) of fill. The dam's spillway is controlled by five gates and has a maximum discharge of 8,467 m3/s (299,009 cu ft/s). To support the reservoir's elevation, there is a 72 m (236 ft) tall saddle dam on the reservoir's rim 2.5 km (2 mi) to the northeast on the Chui Sot River. The reservoir created by both dams has a 2,447,000,000 m3 (1,983,815 acre·ft) capacity of which 2,190,000,000 m3 (1,775,462 acre·ft) is active (or "useful") capacity. The reservoir has a surface of 55 km2 (21 sq mi) and a catchment area of 3,134 km2 (1,210 sq mi). The power station at the toe of the dam contains three 66 MWFrancis turbine-generators and is afforded 84.4 m (277 ft) of design hydraulic head. Below the dam is a system of over 6,300 km (3,915 mi) of canals supported by three barrages and 82 km (51 mi) of main feeder canal.
