The Project envisages construction of a 92 m high and 653 m long concrete gravity dam
. It provides Irrigation
in 1,230 square kilometres of land with annual production of 2700 million units in the districts of Khandwa
and Khargone
in Madhya Pradesh and power generation of 1000 MW installed capacity (8x125). The reservoir of 12200000000 cubic metre was created. The dam, built as a joint venture between Madhya Pradesh irrigation and National Hydroelectric Power Corporation
is the source of the Indra Gandhi canal. It was commissioned on May 2005.
