Union Water Resources Secretary Shashi Shekhar, who chaired the meeting, said the Committee could not arrived at a decision for the want of "adequate" information.
He said the states concerned could not produce adequate information relating to withdrawal of water, its utilisation, allegations of withdrawal when it was not permitted, variation in rainfall and its impact on the actual run-off over a period spanning 29 years.
"...Since the time given by the honourable (Supreme) Court was so limited...They could not bring all information. The Committee did not want to pass any order which is not backed by supportive data.
"So, the Committee has fixed another date, that is on September 19, because the Supreme Court has today given a date for next hearing on September 20," Shekhar told reporters after the meeting.

"All the four states will need to discuss what should be the distress situation. If we arrive at a consensus on that, we will make that a basis for discussion when there is less rainfall and how we can achieve proportionate share then. This (distress) situation is arising regularly," he said.
