The outflow from the Krishnaraja Sagar (KRS) reservoir in Mandya district crossed 1 lakh cusecs on Sunday evening owing to heavy rainfall in the catchment areas of rivers Cauvery and Hemavathi.
Dam authorities confirmed that the outflow from the Hemavathi reservoir in Gorur in Hassan district had been stepped up, which has augmented the rate of inflow into the KRS. Similarly, heavy rain in the catchment area of the Cauvery in Kodagu district since the last few days has augmented the volume of water in all the rivulets and tributaries of the Cauvery, including the Lakshmanthirtha, all of which flow into the KRS.
Besides, the KRS attained its full reservoir level of 124.8 feet in July and hence the authorities have to match the outflow with the corresponding inflow for safety reasons and cannot impound water.
