Rivers too can become a source of conflict between states. A river may begin in one place, flow through another and end in a third. The sharing of river water between different places that the river goes through is becoming an issue of conflict.

For example: Cauvery water dispute between Karnataka and Tamil Nadu. The water stored in Krishnasagar dam in Karnataka is used for irrigating a number of districts and for meeting the needs of the city of Bangalore. The water stored in Mettur dam in Tamil Nadu is used for crops grown in the delta region of that state. A conflict arises because both dams are on the same river. The downstream dam in Tamil Nadu can only be filled up if water is released from the upstream one located in Karnataka. Therefore, both states can't get as much water as they need for people in their states. This leads to conflict. The central government has to step in and see that a fair distribution is worked out for both states.
