While the inflow of water during the period was 1.95 lakh cusecs, the outflow was 1.31 lakh cusecs through eight gates, 21,000 cusecs through the power channels and 4700 cusecs through the canals.

As per the rule curve, the dam authorities should not open two gates each on the left and right spillways unless there is an emergency situation.
