The water from the reservoir having maximum depth of 71 m. and an average depth of 21 m is conveyed to Power House through a water conductor system comprising of 335 m long Headrace Channel, 3934 m long, 7 m dia, circular tunnel terminating at surge shaft 20 in dia 140 m deep, 2 nos. 298 m long 5.25 m dia penstock tunnels and 4 nos. 790 m long 3.5 m dia surface penstocks. The Power Station with 4 x 150 MW installation and operating with an average head of 371 m offers peak power benefit up to 600 MW and annual energy benefit of 1962 MU is a 90% dependable year. The water released from the Power House is carries through a tailrace channel 9000 m long to be finally picked up by the barrage on the river Hati to irrigate 128000 Ha. of land through two flow canals and one loft canals in the chronically drought prone areas of Kalahandi District.
