The dam is 15 kilometers from Sambalpur and was the first large scale, multipurpose river valley project in India after 1947. It was built to control the problem of flooding in Orissa and over 22,000 families were displaced during its making. The dam provides an ideal home for rare species of flora and fauna. Its reservoir receives up to 25 species of migratory birds during winter. The Debrigarh wildlife sanctuary is located here.
