The Mekedatu project: what happened?
Bengaluru needs more drinking water. Tamil Nadu fears a new dam upstream will cut its share. The Cauvery has been the centre of this tug of war for over a century.
- Chief Minister D.K. Shivakumar said 2,500 acres, including forest land, have been identified as alternative land for the forest land the project needs.
- A committee headed by the Deputy Commissioner of Mandya district worked on the land.
- The reservoir would hold 66 tmc (thousand million cubic feet) of water.
- It is meant to supply drinking water to Bengaluru and nearby areas and make about 400 MW of power.
- Tamil Nadu opposes the project.
What is the Cauvery dispute?
The Cauvery rises at Talakaveri in Kodagu, Karnataka, and flows through Karnataka and Tamil Nadu into the Bay of Bengal. Kerala and Puducherry also share its waters.
The Cauvery Water Disputes Tribunal gave its final award in 2007. In 2018 the Supreme Court changed it slightly, giving Karnataka 284.75 tmc and Tamil Nadu 404.25 tmc, and ordered the Cauvery Water Management Authority to be set up.
Tamil Nadu says any new reservoir upstream needs its consent and could reduce flows. Karnataka says Mekedatu is for drinking water and will not affect Tamil Nadu’s share.
Under the Forest (Conservation) Act, 1980, forest land used for projects must be made up for by giving other land for compensatory afforestation. Part of the project area falls in the Cauvery Wildlife Sanctuary.
Which laws and Articles apply?
