Authorities to buildup water levels in major dams

As flood recedes, water drawal to systems like Kalwakurthy is continuing

The irrigation authorities, who have maintained a flood cushion of over 30 tmc ft water both in Srisailam and Nagarjunasagar reservoirs till Wednesday, have started building up levels in both the dams as the inflows have started receding constantly.

Inflows into Jurala, Srisailam and Nagarjunasagar were measured at 7.06 lakh cusecs, 8.63 lakh cusecs and 7.35 lakh cusecs, respectively, at 9 p.m. on Thursday and they are expected to fall further gradually in line with the receding flood into Almatti, Ujjani, Narayanpur and Tungabhadra dams in Karnataka and Maharashtra from where the reservoirs in the Telugu States get the water.

The water storage in Srisailam was about 198 tmc ft (881.8 feet) against its capacity of 215.81 tmc ft (885 ft) at 9 p.m. on Thursday. Similarly, it was about 304 tmc ft (587 ft) against 312 tmc ft (590 ft) in Nagarjunasagar. In Pulichintala, it was 38.74 tmc ft (170.27 ft) against the capacity of 45.77 tmc ft (175 ft).

The drawal of water to all irrigation systems based on Nagarjunasagar, Srisailam and Jurala is continuing. The lifting of water to Kalwakurthy scheme from Srisailam, which was stopped three days back, was resumed on Wednesday night.

Flowing into sea

“With huge quantity of water flowing waste into the sea from Prakasam barrage, about 50 tmc ft during the last few days, the two States have to utilise the water as much as possible when the flood is on.

Pothireddypadu is one such system from where a sizeable volume of water can be taken to the dependent systems. Accordingly, little over 3 tmc ft water a day is being drawn from the system now at the rate of 35,000 cusecs of flow,” a senior irrigation engineer involved in the inter-state issues said.

Compared the systems such as Pothireddypadu, only about 7,500 cusecs was being drawn for about half-a-dozen systems based on Jurala.

“Being one of the best flood flows in the recent years, this year would have helped drawal of good volume of water had Palamuru-Rangareddy been ready,” the engineer felt.
