Durgapur Barrage is built across the Damodar River at Durgapur in Paschim Bardhaman district and partly in Paschim Bardhaman district, in the Indian state of West Bengal. It was constructed by Damodar Valley Corporation mainly for the purpose of irrigation and also to supply water to Industrial township of Durgapur. The irrigation and canal system was transferred to the Government of West Bengal in 1964.

Damodar River is a river flowing across the Indian states of Jharkhand and West Bengal. The valley is rich in mineral resources and is known for large-scale mining and industrial activity. It was also known as the Sorrow of Bengal because of the ravaging floods it caused in the plains of West Bengal. The construction of several dams on the Damodar and its tributaries has helped control some of the flooding.
