Bhakra Nangal Dam is a concrete gravity dam on the Sutlej River in Bilaspur, Himachal Pradesh in northern India. This dam forms the Gobind Sagar reservoir. The dam is situated at a gorge near the (now submerged) upstream Bhakra village in Himachal Pradesh’s Bilaspur district at a height of 226 m. The dam, i.e., 226 m is one of the highest gravity dams across the world. The 166 km2 Gobindsagar Reservoir, named after Guru Gobind Singh, is formed by this dam which is the 3‌rd largest reservoir in India the first being Indira Sagar Dam & second Nagarjunasagar Dam. The Satluj river used to flow through a narrow gorge between two hills, Ramgarh and Naina Devi, and the site was chosen to dam the river.
