When the Mettur dam, the lifeline of the Cauvery delta, clocked an inflow of about 27,400 cubic feet per second (cusecs) on Monday morning, this was the highest quantity of Cauvery water realised by the dam since the beginning of this year’s water year (June-May).

In other words, the inflow was equivalent to 2.4 thousand million cubic feet (tmc ft). Given the present drawal of water from the dam, it would have met the requirement for two days had 2,000 cusecs more been received.

In the morning, the water level of the dam stood at 71.84 ft (capacity: 120 ft) with a storage of 34,301 tmc ft (capacity: 93.47 tmc ft).

The outflow was 14,705 cusecs. At 4 p.m., the level rose to 72.05 ft.

Heavy rain

Officials of the Water Resources Department in Mettur attributed the enhanced flow to heavy rain upstream Mettur. At one point on Sunday, the inflow was as high as 29,926 cusecs.

As a sequel to the Supreme Court’s directions early last month, the realisation of the Cauvery water at Mettur was around seven tmc ft between September 12 and September 19, the day the Cauvery River Authority (CRA) held its meeting. Since September 20, the State realised around 12 tmc ft. Totally, the cumulative receipt was about 19 tmc ft.

Since June 1, the State, till now, received approximately 36 tmc ft. Going by the interim order of the Cauvery Water Disputes Tribunal, the shortfall was nearly 110 tmc ft.
