Even as memories of the November 2017 floods in Chennai haunt southern India comes the disturbing news that almost all big dams in Cauvery basin are full and flowing above the danger mark. However, the Central Water Commission (CWC), India's flood forecasting agency has allegedly still not updated its flood readings. Currently, the Krishnaraj Sagar, Mettur, Kabini, Harangi, Hemavathi and Bhavanisagar dams are releasing excess water downstream. "The next 2-5 months are critical for the region as it faces a major risk of floods," said Himanshu Thakkar of the South Asia Network for Dams, Rivers & People. He added, "The CWC has not even bothered to update the flood readings on its designated sites from the 2017 figures."

Both Tamil Nadu and Karnataka have shown poor performance in managing dams to avoid floods. The recently CAG report has clearly said that the wrong operation of dams in Chennai led to avoidable floods. Karnataka too, has just last week suddenly released huge quantity of water from Tungabhadra dam, submerging the world heritage sites at Hampi downstream.

Karnataka water resources minister Mallanagouda Basanagouda Patiltried said, "It is great to see the PM take an aerial survey of flood-affected areas, but the Centre needs to do more." His Tamil Nadu counterpart S P Velumani said, "When we need water, Karnataka refuses to release the water that we have been allocated and the Centre does not intervene. Now we have a situation of plenty and they want to release large quantities of water daily."

Deputy director of the Flood Forcecast Monitoring, Detection & Flood Control department of the CWC S Lakshminarayanan brushed off the allegations. "We have provided all the inputs necessary," he said admitting, "The water levels are a matter of concern and we want the states to release enough of it so that any emergency is averted."
