A feasibility study carried out for WAPDA concludes that the project should comprise a curved, 133m high, roller compacted concrete gravity dam with a radius of 150m. A spillway is to be built on the middle part of the dam, initially with four bays, four long chutes and flip buckets. Maximum capacity of the spillway will be 433m3/sec. A 2.2x3m bottom outlet opening, with a discharge capacity of 250m3/sec, will be placed at 29.9m above the river bed. A 17.4MW power house will be situated in a cavern 18m high, 9m wide and 37m long.
