With the clamour growing louder for the construction of a dam at Mekedatu across the Cauvery, activists have raised concerns over the impact such a project. would have on the environment. They are worried that the project will lead to the submersion of nearby villages and loss of habitat of the critically endangered hump-backed Mahseer fish.
The Cauvery is the lifeline for farmers in Karnataka and Tamil Nadu as the river water irrigates vast swathes of land in both the States. The Karnataka government plans to construct the dam to provide water to the farmers. The Congress State unit had staged a padayatra from Mekedatu to Bengaluru early this year demanding the implementation of the project.
Activists and retired officials have questioned the need for the dam. Joseph Hoover, former member, Karnataka State Wildlife Board (KSWB), said, “The dam project will not only submerge vast areas of forests, it will also impact the future of the endemic fish. Professional anglers have already sounded the alarm about insensitive people introducing fish species from Amazon in the river.”
