The primary purpose for the barrage is irrigation but it also serves to provide water for hydroelectric power production and control floods.

The area behind the barrage is known as the Neel Dhara Bird Sanctuary and is a popular destination for various waterbirds and tourists.

The initial barrage was constructed between 1840 and 1854 to supply the Upper Ganges Canal with water and control flooding.

[3][4] The barrage is 455 m (1,493 ft) long and sits at the head of a 23,000 km2 (8,880 sq mi) catchment area.

Although both power plants are owned by Uttaranchal Jal Vidyut Nigam Ltd., canal flows are regulated by the Uttar Pradesh Irrigation Department.
