Srisailam reservoir swells with inflows
KURNOOL: Copious inflows from the reservoirs upstream Krishna river have started making Srisailam Reservoir swell with water and in couple of days, the gates of the project will be opened to release the water downstream to Nagarjuna Sagar.
The project is receiving inflows at the rate of 2,51,450 cusecs, of which inflows at the rate of 1,64,450 cusecs is being received from the Jurala barrage in Mahbubnagar district of Telangana state and at the rate of 87,000 cusecs from the Tungabhadra dam.
For the last two days the inflows to Srisailam reservoir have increased from both Jurala and Tungabhadra, as both the projects built upstream of Sirsailam were receiving copious rainfall from their catchments areas with both Krishna and Tungabhadra rivers being flooded with rainwater in Karnataka.
The Tungabadhra dam in Karnataka state has 1,632.16 feet of water levels at present against the FRL of 1,633 feet. At present, it is receiving inflows at the rate of 1,54,033 cusecs and letting out water downstream into Tungabhadra river at the rate of 1,71,842 cusecs, forcing the lifting of 33 gates.
It resulted in heavy inflow to the Srisailam reservoir. On the other hand, with the Narayanpur dam in Karnataka, upstream of Jurala in Mahbubnagar district, has also received copious inflows, with all the gates of Almati dam lifted to let out the flood water.
Water is being released from Narayapur at the rate of 1,51,494 cusecs, which had brimmed Jurala project and it had opened its gates and let out the flood water downstream at the rate of 1,66,000 cusecs. The copious inflows are expected to continue for some more days.
According to Srisailam project officials, the water levels at present stand at 850.51 feet against FRL of 885 feet. However, it has not yet opened its gates to release the water downstream to Nagarjuna Sagar as there is a High Court direction that it had to release the waters downstream only when the level rises above 854 feet.
Officials are expecting the water level to cross that point in a couple of days and they have to release the water downstream. However, they are releasing 9,402 cusecs of water from the reservoir for power generation purpose at its hydro-electric trubines on the left bank (105x1 unit).
