‘K’taka rainfall at 40-year low’
During the meeting, Karnataka insisted that rainfall in Cauvery catchment area is at a 40-year low and the state is not in a position to release water. Officials from TN, however, contended that Karnataka should have released over 40 tmcft of water in last two months, but only 9.505 tmcft has been released from June 1 to July 31. TN urged the committee to direct Karnataka to release water.
