Hyderabad: Two flood gates of the Srisailam projects were lifted letting out 56,000 cusecs of flood water on Thursday. The Srisailam outflow will add to the inflows of the water-starved Nagarjunasagar dam within 24 hours.
AP Minister for Irrigation Devineni Uma Maheswar Rao who visited the Srisailam project along with the Engineering officials opened the gates after performing formal Puja at the dam site.
The project is receiving inflow of 1,40,818 cusecs while its water level touched this morning 884.5 ft as against the full reservoir level (FRL) of 885 tmc. The gross storage in the reservoir is 210 tmc as against the gross capacity of 213 tmc.
The Srisalam Chief Engineer, Narayana Reddy said on Wednesday that three of the spill gates would be lifted to let out 84,000 cusecs. But there was a change in the AP plans and only two of the gates (No 6 and 7) were lifted this morning.
Initially, he said there may not be any need to operate the flood gates at all as some 80,000 cusecs were being released through the power house channels. But the inflow continued to more than the outflow, and AP irrigation officials were left with no scope to retain more than the gross capacity of the dam.
The project is full to the brim after a gap of three years and it holds hope for Nagarjunasagar project and its command area spread over Nalgonda, Suryapet and Khammam distrcts in Telangana and Krishna, Guntur and Prakasham in Andhra Pradesh.
No water was released from either the NSP Left Canal or The NSP Right Canal for irrigation so far this year. The inflow into Nagarjunasagar were in the order of 74,614 cusecs this morning.
The project level is still at 528.2 ft as against the Full Reservoir Level (FRL) of 590 ft.
