Tamil Nadu Chief Minister C Joseph Vijay will move a resolution in the state Assembly on Friday against Karnataka's move to construct a dam across river Cauvery at Mekedatu, official sources said.

The resolution would urge the Centre to not give technical and environmental clearance.

Karnataka was trying to implement the project "unilaterally," and it should get the consent of other stakeholder States.

Tamil Nadu has been opposed to Karnataka's move to construct the balancing reservoir at Mekedatu in that State, claiming it would affect its interests.

Karnataka has been insisting that the reservoir, proposed to meet the twin objectives of Bengaluru's drinking water requirements and power generation, will not harm Tamil Nadu's interests.
