Gobind Sagar, Hydroelectric reservoir in Bilaspur, India

Gobind Sagar is a reservoir formed by the Bhakra Dam on the Sutlej River, lying in Bilaspur and Una districts of Himachal Pradesh. It measures about 56 km in length and nearly 3 km in breadth. The Bhakra Dam, one of the world's highest gravity dams, rises nearly 225.5 m above its lowest foundations.

Construction of the Bhakra Dam began in 1955 under American engineer Harvey Slocum, leading to the creation of this large reservoir. The flooding of the valleys was completed in 1962, permanently changing the landscape and way of life for residents along the Sutlej River.

The reservoir is named after Guru Gobind Singh, the tenth Sikh guru; the name was proposed by Harbans Singh Somal, former chairman of the Punjab State Electricity Board. In October and November, when the water level is high, the Tourism and Civil Aviation Department organises a series of regattas on the water. The Naina Devi temple, about 20 km away, draws thousands of pilgrims to a large fair in August.

The reservoir sits in a mountainous region with changeable weather, so visitors should prepare for sudden temperature shifts and fog. Between August and January, conditions for water activities are more favorable, as water levels remain stable and currents are less pronounced.

Gobind Sagar was declared a water fowl refuge in 1962, the year the Bhakra Dam was completed. About fifty-one species and subspecies of fish live in it, among them Bangana dero, Tor putitora, Sperata seenghala and mirror carp. The reservoir's name was proposed by Harbans Singh Somal, then chairman of the Punjab State Electricity Board, in honour of Guru Gobind Singh.
