During favourable monsoons, large volumes of water is pushed into the Bay of Bengal. To arrest this, Karnataka Ministers HD Devegowda and son (HD Revanna) have tabled a representation of the construction of a balancing reservoir on Cauvery dam to the Union Minister, Gadkari.
The dam, which is estimated to cost Rs. 6,000 crores will have a capacity of 67 tmc feet (thousand million cubic). The proposed site for the project is Mekedatu, a township on the border of Tamil Nadu and Karnataka. Around 5,000 acres will be the land-take which will also house a 400 MW hydel power generation station.
As per the Cauvery Tribunal’s order, Karnataka is expected to release 192 tmc feet of water per normal year to TamilNadu, however, the State is concerned that water wastefully flows into the sea in normal monsoon years.
The project will aid in regulating the water flow – enabling the State to address its drinking water needs while also strengthening the water table.
Union Minister Gadkari has responded favourably to the proposal, according to reports. He has said that the matter will be discussed with Tamil Nadu.
