On Thursday morning, project engineers lifted 10 gates of the Nagarjuna Sagar Project (NSP) by 10 feet due to increased inflow. The gates were raised by NSP Chief Engineer Srikanth Rao by pressing a switch on the control board.
With the project gates raised, about 1.10 lakh cusecs of water are released downstream. The inflow to the project was 4,72,708 cusecs and the outflow was 40,625 cusecs.
The water level in the project was 586.7 feet as opposed to 590 feet at the full reservoir level. There are currently 303.94 TMCs of water stored in the project, compared to 312.04 TMCs of gross storage.

Large inflows received by Nagarjuna Sagar reservoir
The Nagarjuna Sagar reservoir is nearly full due to the massive discharge from the Srisailam reservoir (3.29 lakh cusecs). The current water level at Nagarjuna Sagar is 575.50 feet, compared to the Full Reservoir Level of 590 feet, and with inflows reaching 1.69 lakh Cusecs, the crest gates at Nagarjuna Sagar are likely to be lifted on Friday. According to irrigation engineers, inflows could reach 3 lakh cusecs by Friday evening.
Telangana Irrigation engineers have hinted that the crest gates at Sagar may be lifted on Friday morning, and Andhra Pradesh Irrigation engineers have begun taking precautionary measures.
The Pulichintala balancing reservoir is also receiving good inflows, with a current water level of 152.46 feet and a capacity of 17.70 tmcft, up from 45.77 tmcft. Because storage at Prakasam Barrage is limited at 3.05 tmcft, a massive discharge from the barrage is possible in the coming week.
Due to heavy inflows from upstream, the Godavari remained dangerously high in Andhra. The authorities at Dowleshwaram barrage near Rajahmundry lifted the gates, releasing 10 million cubic seconds of water to the downstream, and notified villages in Konaseema’s low-lying areas.
On Wednesday, continuous rains in the Godavari river catchment areas for the last two days posed an inundation threat to low-lying areas in both the Telugu states of Telangana and Andhra Pradesh.
