Mekedatu Project

Subject – Geography

Context – Tamil Nadu has been opposing the Mekedatu project and unanimously passed a resolution urging the Union government not to accord permission to Karnataka to construct the reservoir.

Concept –

• The Mekedatu multi-purpose project involves building a balancing reservoir across the Cauvery River near Kanakapura in Ramanagaram district.
• It envisages supplying drinking water to Bengaluru and Ramanagaram districts, besides generation of power.
• The project was conceived in 2013 and in 2017, the Karnataka state cabinet decided to implement it.
• The project, however, ran into a controversy after Tamil Nadu opposed it on the grounds that the project violates the Cauvery Water Disputes Tribunal award.
