The cumulative outflow from the Krishnaraja Sagar (KRS) and the Kabini reservoirs between June 1 and September 10 has been higher compared to the outflow in the same period during the last three years.
Above normal rainfall during the current monsoon season has resulted in heavy inflow to the reservoirs as a result of which the corresponding outflow was also steady and high. Against Karnataka’s obligation to release 177.25 thousand million cubic feet (tmcft) to Tamil Nadu during a water year (June to May), the cumulative outflow from the two dams from June 1 to September 10 was 291 tmcft, according to Karnataka State Natural Disaster Monitoring Centre (KSNDMC).
The outflow from the KRS on September 10 was at the rate of 20,913 cusecs and it was 15,550 cusecs from the Kabini. At this rate, the cumulative discharge since June is expected to cross the 300-tmcft mark within the next few days.
