Four of the 12 radial crest gates of the Srisailam project were lifted on Friday evening, letting out one lakh cusecs of water into Nagarjuna Sagar Project.
Ministers from Telangana S Niranjan Reddy and V Srinivas Goud joined Andhra Pradesh Minister for Irrigation P Anil Kumar at the project site to perform the formal pooja for the river goddess before releasing water.
NSP has an ayacut of 23 lakh acre in both Telangana and Andhra Pradesh, and the release of water from Srisailam should bring cheer to farmers in both the States. In fact, the water release to NSP was scheduled for Saturday, but was advanced in view of the sudden rise in discharge from upstream projects in Karnataka.
Radial crest gates No 6 , 7 , 8 and 9 of Srisailam project were opened one after the other as water began gushing out of the project and touched the full volume of 25,000 cusecs from each one of them within minutes.
The release provided an exhilarating sight for those present at the dam.
One or two more gates are likely to lifted late in the night depending on the inflows received. The inflow into the project is in the range of 3.16 lakh cusecs and it is rising further. About 1.69 lakh cusecs of water is being received from Tungabhadra river. The

The project’s live storage was 193 tmc against its designed gross capacity of 215.81 tmc at the full reservoir level of 885 ft. The project is receiving more than 40 tmc of water a day with all the upstream projects including Jurala in Telangana maintaining heavy outflows. In addition, Bhima river, which is in spate, is also expected to add another 2.5 lakh cusecs tonight.
