Water level in the reservoir reached 882.6 ft at 9 pm on Tuesday and storage level of 202.5 tmc ft against the full reservoir level of 885 ft and capacity of 215.81 tmc ft. Similarly, the water level in Nagarjunasagar downstream reached 550.5 ft at 9 pm against the FRL of 590 ft and the capacity to 210.9 tmc ft as against the capacity of 312 tmc ft.
However, the inflows began to pick up again on Tuesday afternoon both from Tungabhadra and from Krishna (Jurala) as the Central Water Commission (CWC) has issued a forecast that flood to all reservoirs upstream of the basin in Karnataka is expected to rise again.
The inflows into Srisailam were recorded at 1.23 lakh cusecs on Tuesday night and expected to cross over 2 lakh cusecs again on Wednesday morning due to increased discharge of flood from Sunkesula Barrage on Tungabhadra and Jurala project on Krishna.

Meanwhile, the position of water level changed overnight in Sriramsagar as it received about 21 tmc ft water from 6 pm on Monday to 6 pm on Tuesday and its storage was over 58 tmc ft at 9 pm against the capacity of 90.31 tmc ft with the inflows recorded at 2.65 lakh cusecs.
