Ichari Dam

The Ichari Dam is a concrete gravity dam on the Tons River north of Dakpathar in Uttarakhand, India. The primary purpose of the dam is hydroelectric power production and it is a run-of-the-river-type. It was completed in 1972. The dam diverts water to the Chibro Power Station which is then returned to the Tons River before being fed to the Khodri Power Station.

Design and operation

The dam is a tall and long concrete gravity type with a structural volume of. The dam's spillway is located across its crest and is controlled by seven floodgates. It has a maximum discharge capacity of. The dam's reservoir has a capacity, of which is active capacity. The surface area of the reservoir is.

Chibro Power Plant

Adjacent to the dam and on its left bank, water is diverted into a head-race tunnel which leads south to the underground power station at. There, the water powers four 60 MW Francis turbine-generators. The design hydraulic head of the station is and its design discharge is. The plant was commissioned in 1975 and was the first power plant built underground in Northern India.

Khodri Power Plant

Water discharged from the Chibro Power Plant is returned into the Tons River just upstream of the intake for the Khodri Power Station. Water enters the intake and then travels south down a head-race tunnel which leads to the power station on the Yamuna River at. There, the water powers four 30 MW Francis turbine-generators before being discharged into a tail-race channel behind the Dakpathar Barrage. The design hydraulic head of the station is and its design discharge is. The plant was commissioned in January 1984.
