The reservoir Gobind Sagar is on the river

The Gobind Sagar reservoir is located on the Sutlej river in the Bilaspur and Una districts of Himachal Pradesh [c1, t1, t4]. It was formed as a result of the construction of the Bhakra Dam, which is one of the highest concrete gravity dams in the world [c1, t7]. The reservoir is named in honor of Guru Gobind Singh, the tenth Sikh Guru [c1, t1]. It is a major multipurpose project providing irrigation and hydroelectric power to states like Punjab, Haryana, and Rajasthan [c1]. It is important to distinguish this from the 'Govind Ballabh Pant Sagar', which is the reservoir of the Rihand Dam located on the Rihand river (a tributary of the Son river) in Uttar Pradesh [c2, t9]. While both are named after prominent figures named 'Govind', the Gobind Sagar specifically refers to the Sutlej river project [t1, t2].
