The Mettur dam, the primary storage point of Cauvery water in the State, is likely to soon witness a steep rise in its inflow, with the authorities in Karnataka beginning to release huge quantities of water from the Kabini dam.

At 4 p.m. on Wednesday, the Kabini dam, which recorded an inflow of 35,000 cubic feet per second (cusecs), saw an outflow of around 40,000 cusecs. On Tuesday, the outflow from the dam was around 30,000 cusecs. As of now, the Mettur dam has recorded an inflow of 3,600 cusecs.

Heavy rain in the last few days over the Kabini’s catchment area at Waynad in Kerala has led to a huge inflow into the dam in Karnataka.

Another development that comes as a relief to water managers of Tamil Nadu is that parts of the Cauvery’s catchment area in south interior Karnataka have also been recording substantial amounts of rain.

Unlike the Kabini dam, which has reached around 90% of its capacity, the Krishnaraja Sagar (KRS) dam’s figure is around 60% and, as such, the chances of the release of excess water from the dam are remote for the next few days.

The inflow into the KRS dam was around 20,000 cusecs.

As of Wednesday, the Mettur dam’s storage stood at 27.88 thousand million cubic feet (tmc ft), as against a capacity of 93.47 tmc ft. The water level stood at 64.16 ft, as against the full level of 120 ft. The discharge was 3,000 cusecs.
