Gobind Sagar Lake is a reservoir situated in Una and Bilaspur districts of Himachal Pradesh. It is formed by the Bhakra Dam. The reservoir is on the river Sutlej and is named in honour of Guru Gobind Singh, the tenth Sikh guru. One of the world's highest gravity dams, the Bhakra dam rises nearly 225.5 m above its lowest foundations. Under the supervision of the American dam-builder, Harvey Slocum, work began in 1955 and was completed in 1962. To maintain the water level, the flow of the river Beas was channelized to Gobind Sagar by the Beas-Sutlej link which was accomplished in 1976.
