Hyderabad: With Srisailam dam level close to reaching its gross storage capacity of 215.807 tmc, the project authorities in Andhra Pradesh have decided to let out 84,000 cusecs of water to Nagarjunasagar Dam.
The Srisailam Project Chief Engineer Narayana Reddy told Telangana Today that the AP Irrigation Minister Devineni Uma Maheshwara Rao will open three spill gates of the project, each letting out about 28,000 cusecs on Thursday morning. “We will review the inflows thereafter to look into the scope of increasing further the volume of outflows” he said.
The project inflows have been consistently above one lakh cusecs for quite some time following heavy rains in the catchment areas. All the upstream projects, including Alamatti, Narayanpur and Jurala, are full to the brim following heavy rains in the catchment during the past ten days.
The TS OSD (Irrigation) Sridhar Rao Despande said the inflows into the Srisailam project were 1,50,000 cusecs at 3 pm. The Srisailam reservoir level touched 884.4 ft, against the FRL of 885 ft during the day. The increase in the outflow from Srisailam project would benefit the Nagarjunasagar project where the water level was 527 ft against the FRL of 590. More rains have been forecast in the catchment areas of Krishna basin, which will bring happy tidings for farmers in the catchment area of the common projects of the two Telugu States – Srisailam and Nagarjunasagar.
NSP authorities hopeful
The NSP Chief Engineer, S Suneel, told TelanganaToday that a decision on giving water for irrigation to the ayacut of both the NSP left canal and NSP right canal can be taken in the next meeting of the Krishna River Management Board (KRMB) which will be held after Deepavali (most likely between October 22 to 31).
NSP will be getting sufficient inflows once Srisailam touches the FRL of 885 feet. Srisailam cannot retain more than its estimated live capacity. The NSP has a flood cushion of 157 tmc, he explained.
