Durgawati and the Karmanasha rivers are the perennial sources of surface water. A high level canal from Indrapuri (Dehri) has been irrigating the southern parts of this district. The canal is about 84 Kms long and irrigates about 34000 hectares of land during Kharif season and about 9000 hectares of land during Rabi season. The southern part of Kaimur district has a number of canal systems such as Durgawati Main Canal, Garachaube canal etc.
In the hilly tracts of Adhaura, Chainpur and Bhagwanpur blocks, only ditches and ponds are used to conserve rainwater. New techniques of water conservation and harvesting practices are needed in plain as well as these hilly areas to utilise rainwater. Reservoir tanks can store water from hill streams and rivulets especially when "Hathia" rain falls, which also provide irrigation during Rabi season. Water table in the plain areas is low and high yielding tube wells can sustain at a depth of 70-100 meters whereas small tube wells may get the aquifer zone within 25-30 meters depth. The normal depth of water table is 5-10 meters in winters and up to 15 meters in summers.
