MYSORE: Floodwater flow from Kabini dam could dampen down the rising tempers between Karnataka and Tamil Nadu in the Cauvery water crisis.

Water outflow from the dam in H D Kote in Mysore was stepped up on Tuesday following rise in inflow to the reservoir. The inflow which started to rise since a week jumped to 24,000 cusecs following which the outflow is stepped up. Presently, the dam is releasing 10,000 cusecs, which could go up given the inflow following copious rainfall in Waynad district in Kerala. The water released will flow towards Tamil Nadu, which could help in easing the building tension between the two riparian states.

The water outflow is stepped up on a day when the TN government approached the SC seeking 10 tmcft immediately arguing that Karnataka has received 26 tmcft water in ten days.

This comes amidst TN government’s decision on June 15 to approach the apex court for the constitution of Cauvery Management Board and Cauvery Water Regulatory Authority after the first meeting of the supervisory committee chaired by the Union water resources secretary failed to arrive at a consensus on the TN’s demand for water.

Sources told The Times of India that water release was stepped up from Tuesday morning following increase in the inflow gauged at Bavali on Karnataka-Kerala border. The outflow was 5,000 cusecs on Monday. As the inflow picked up steadily, the floodwater is let out. The dam was receiving 10,000 cusecs since a week.

The dam’s level was 2,278 ft. The maximum level of the dam is 2,284 ft. “We’re planning to maintain the dam’s level at 2,280 ft and releasing 10,000 cusecs following sudden rise in the inflow,” executive engineer (Kabini dam) K M Mariswamy told TOI. He refused to specify the quantum of water that has flowed out of the dam while chief engineer (South) Shivashankar didn’t attend to the calls. A senior officer of the Cauvery Neeravari Nigam, who didn’t wanted to be named, said the water is released following the rise in the inflow.

As per the final award of the Cauvery Water Disputes Tribunal, Karnataka has to release 134 tmcft to TN between June and September, which the Karnataka is seeking to review arguing that it is not possible to release the stipulated quantum during the four-month period. CM Siddaramaiah has told the assembly that the state is proposing to revise it downwards to 97.82 tmcft.

The outflow is also increased from KRS dam in Mandya. As against a maximum 124.8 ft, the level was 80 ft. The inflow was 3,484 cusecs while 2,800 cusecs is released to the river. The dam has 2.38 tmcft live storage. The inflow is likely to increase as rainfall is pounding Kodagu district in the last two days.
