Incessant rain in Telangana filling Nagarjuna Sagar dam

On average, the volume of water reaching the NSP over the last few days is about five tmcft per day. The NSP has received 41 tmcft since June this year.

The NSP began filling up after three gates of the Srisailam Project were opened on Saturday with the water level reaching the maximum permissible limit. The inflows picked up into the project following heavy downpour in the catchment areas of the river upstream in Karnataka and its tributary Tungabhadra.

The gates were lifted after the water level reached 881.6 ft as against its FRL of 885.1 ft, allowing a discharge of 80,000 cusecs to NSP. At present, the outflows are 76,294 cusecs and the inflows into the reservoirs were 50,380 cusecs.

The five underground Hydel stations on Srisailam’s left bank are being operated to generate power since 22 July. At Pulichintala hydel unit,  50 MW of power is being generated since Sunday evening.

The water that is being received at Pulichintala which is downstream of Nagarjuna Sagar is the one that is used for the generation of power by NSP’s hydel station. There is no regular discharge at NSP as the project is yet to fill up.

The India Meteorological Department has predicted rains in parts of Telangana under the influence of a trough of upper air circulation in Madhya Pradesh which is triggering rains in Telangana.
