Water levels rise in Cauvery basin reservoirs

Water levels rise in Cauvery basin reservoirs

The water crisis that loomed large during the summer is slowly easing with water levels in four major reservoirs in the State recording a significant increase.

According to water levels recorded at reservoirs in the Cauvery basin on Thursday, the live storage above sill level at the KRS (Krishnaraja Sagara) stood at 0.631 tmc (thousand million cubic) feet. At the Kabini it was 0.706 tmc feet, the Hemavathi (2.145 tmc feet) and the Harangi (1.195 tmc feet.)

A week ago on June 6, the water level at the KRS was 0.930 tmc feet (the level reduced a week later mainly due to the drawal by Bangalore, Mysore and other places for drinking water purpose. BWSSB draws water from Thorekadanahalli).  A week ago, the Kabini recorded zero feet and the Hemavathi recorded 1.930 tmc feet and Harangi 0.867 tmc feet. 

Increased inflow

There has been an increase in the inflow into these reservoirs owing to the heavy rainfall recorded in coastal parts of Karnataka. An official from BWSSB noted that, the major inflow was due to heavy rainfall in the past four days. This made a difference in the water level at the KRS reservoir.

On June 13, the inflow at the KRS was 481 cusecs, the Kabini  3,652 cusecs, the Hemavathi 1,395 cusecs and the Harangi 1,137 cusecs.  The official said that, although the inflow was much higher than that in 2012, the storage levels were low compared to the previous year.

The official further explained that in 2012, the monsoon had failed miserably which resulted in less inflow.  However, with more storage in reservoirs, water supply was facilitated to Bangalore, Mysore, Mandya and Ramanagar during the summer.  

The failed monsoons last year resulted in one of the worst water crisis in the history of the State.  After the State released water to Tamil Nadu following Supreme Court's directions last year, the government had even mooted rationing of water supply to consumers.

However, the proposal was immediately withdrawn in view of the impending Assembly elections.
