Irrigation water for Jharkhand is provided through 16,882 check dams and through several large and small reservoirs. There is a proposal for creation of irrigation potential from existing Konar Dam and Balpahari dam, if constructed.
Irrigation water for the command area of Lower Damodar Valley in West Bengal is supplied mainly through 8 nos. head regulators of Left Bank Main Canal (LBMC) at down-stream of take off point from Durgapur Barrage (constructed by DVC in 1955 and subsequently handed over to the Govt. of West Bengal in 1964 on agency basis for operation and maintenance of the system).
