Damodar River (Pron:/ˈdæməˌdɑː/) is a river flowing across the Indian states of West Bengal and Jharkhand. Rich in mineral resources, the valley is home to large-scale mining and industrial activity. Earlier known as the Sorrow of Bengal because of its ravaging floods in the plains of West Bengal, the Damodar and its tributaries have been somewhat tamed with the construction of several dams.
