Talks between chief ministers of Karnataka and Tamil Nadu on sharing of the Cauvery river water failed Thursday, as Karnataka declined to release any more water due to depleting levels in its drought-hit reservoirs. "The Karnataka government has refused to release any more (Cauvery) water though we requested its chief minister (Jagadish Shettar) for releasing 32 tmcft (thousand million cubic feet) of water for the next 15 days to help our farmers," Tamil Nadu chief minister J Jayalalithaa told reporters after an hour-long talks  with her Karnataka counterpart here.

Disappointed over the failure to find an amicable solution, Jayalalithaa said her government counsel would inform the Supreme Court on Friday about the outcome of the talks, which were held as suggested on Monday by the division bench of the apex court.

"We will approach the Supreme Court tomorrow (Friday) again for directing Karnataka to release additional water due for us to save the standing (samba) crops," Jayalalitha said.

Expressing inability to spare more water, Shettar said the state was not in a position to meet Tamil Nadu's demand, as a severe drought, a weak (south-west) monsoon and deficit rainfall in the catchment areas of the river basin have led to drastic fall in the rain-fed reservoirs.

"We need to look at our requirement before sharing with Tamil Nadu. As we need water for our farmers, we cannot give more to Tamil Nadu," Shettar said.
