Karnataka is learnt to have said that it will try to release Tamil Nadu's remaining share of 10 TMC at the earliest.
The Committee, headed by Union water resources secretary Alok Rawat, also refused to extend an assurance saying it can only report the quantity of water released by Karnataka to the Supreme Court at the end of the month.
It was also pointed that Tamil Nadu has received more than 60% of its monthly demand in the first two weeks of July.
Tamil Nadu is understood to have pointed that the water flow was due to monsoon and Karnataka should release its share as per the Cauvery Water Disputes Tribunal award notified in February this year.
The water resources ministry will release the minutes of the meeting on Tuesday.
During the meeting, Pudducherry said it wants to set up two water guaging stations. While there was a general agreement on the issue, it was asked to make its demand in writing. Tamil Nadu said it would respond to Pudducherry's demand in writing after studying the proposal.
