"Both the states were requested to co-operate and see how best they can handle the shortfall situation collectively," sources said after the meeting of Cauvery Supervisory Committee here.
Karnataka had earlier this month expressed an inability to release Cauvery waters to Tamil Nadu saying it was facing its "worst drought" in over four decades.
"We are trying to improve data collection and data management and analysis so that this kind of distress situation can be understood well and appropriate decisions can be taken," the sources added.
The shortfall, Tamil Nadu said, has been affecting ongoing cultivation of samba crop and, thus, the state's food security.
Tamil Nadu also demanded that the Committee ensure delivery of 48 TMCft of water due to the state at Billigundulu for the months of October-January as prescribed in the final order of the tribunal. It further charged that Karnataka overdrew 37 TMCft water above the 103 TMCft it was entitled to in 2014-15.
The Committee, Tamil Nadu insisted, should ensure that Karnataka does not draw water for summer irrigation and the balance storage is carried over for use in the next irrigation season.
"Such problems are surfacing mainly because Tamil Nadu gets water only when Karnataka releases it. Hence, to ensure impartial distribution of water in line with the tribunal's order, Tamil Nadu wants constitution of Cauvery Management Board and Cauvery Water Regulation Committee without delay with reference to assurances given by Centre to Supreme Court as on May 10," the sources said.
