Project Description

The project comprises of an earthen dam on River Durgawati (Karmanasha basin) joining Shergarh Hills on the right and Rajdeo Hills on the left. The ultimate irrigation potential of the Project is 36,317 hectare. The command area of this project is spread in five block of Kaimur and Rohtas districts. A Feeder Outlet is located in the spillway of the dam which releases water for stabilization of irrigation due to an old scheme viz. Kudra Weir Scheme. The command of Kudra Weir scheme (16,020 ha) has now been internalized in the command of Durgawati Reservoir Project ( 16,020 + 20,297 ha = 36,317 ha). Kudra weir project (Durgavati canal)construction in the year 1954-55 and was completed in 1964-65. In order to make use of storage of Duravati reservoir, the Kudra weir and distribution system was remodelled and completed in the year 2006.

The Kudra weir on Durgawati river downstream of the dam is 59.741 meter long and its height above river bed level is 2.286 meter and the canal taking off from the weir is 34.778 km long with head discharge capacity of 9.34 cumec.The CCA is 21,100 hectare and potential is 16,020 hectare.

The Durgawati dam is an earthen dam whose length is 1616 meter and the height is 46.66 meter. Two canals take off from thedam. the left bank canal is 25.27 km and head discharge capacity is 6.46 cumec. The right bank main canal is 32.07 km with head dischage capacity of 13.88 cumec. The CCA from these canal system is 17,890 hectare and potential is 20,297 hectare.

The project is receiving CLA under AIBP and so far irrigation potential of 3300 hectare has been created under this project, other than that of from existing Kudra Weir.

The project has received investment clearance of Planning Commission in the year 2000 for an estimated cost of Rs 231.41 crore (1998 price level).
