"I will take up the matter relating to Kalma barrage gates with the Union Water Resources Ministry and Central Water Commission to ensure that flow of water in Mahanadi river through Odisha is not affected," Pradhan told reporters.
The Union Petroleum Minister further said that he would also take up the issue with the Chhattisgarh government on behalf of the BJP in order to safeguard the interests of the people of Odisha.
Meanwhile, BJD spokesperson and Food Supplies & Consumer Welfare Minister S N Patro said any dispute over water sharing between two states needs to be resolved in a democratic and federal set-up under inter-state principles by organisations like Central Water Commission (CWC).
If the dispute remained unresolved, the state would have to approach the Central Government and if nothing concrete emerges it may move the Supreme Court, he said.

There is "widespread unrest" due to the "unilateral action", Patnaik said adding "This unrest may go out of hand, if free flow downstream of Kalma barrage in Mahanadi river is not restored immediately.
