A Sudden burst of Flood Water to Srisailam

Srisailam receives a  sudden burst of flood water from Jurala to Srisailam between 3 p.m. and 6 p.m. on Thursday. Considerably shot up the storage of water at the Srisailam reservoir under the impact of heavy flow in river Krishna from projects in Karnataka. Officials at the Srisailam dam site expected the storage at the reservoir to go up by five to eight tmc ft by Friday evening if the flows continued at the same level.

The inflows from Jurala went up from 73,000 cusecs at 3 p.m. to 1.35 lakh cusecs at 6 p.m., taking the storage to 50 tmc ft against a capacity of 216 tmc ft. The water level was 830 ft against the full reservoir level (FRL) of 885 ft. The water release into Srisailam from Jurala had never exceeded 30,000 to 40,000 cusecs since the first discharge on July 21 when the level was only 788 ft. The AP government which was allowed to draw seven tmc ft from Srisailam for drinking water needs in Prakasam and Guntur districts through the right bank canal discharged 12,000 cusecs into Nagarjunasagar after power generation. Another 6,600 cusecs was left into the canal.

The situation was equally impressive in Godavari as Sriramsagar project which received inflows after a gap of two years stored 46.201 tmc ft against the full capacity of 90 tmc ft. The inflow of 13,000 cusecs in SRSP was aided by the gates of Babli and other upstream projects – Balegaon, Amdura and Vishnupuri – being kept open by the Maharashtra government as per the Supreme Court judgment up to October. Maintaining a constant level of 2.5 tmc ft at Vishnupuri, Maharashtra officials kept releasing .5 tmc ft to SRSP at regular interval.

The SRSP was a sad story last year as the storage was only 6.8 tmc ft and level 1,051 ft against na FRL of 1,091 ft by this time. The Telangana government released for the first time water into Kakatiya and flood flow canals of SRSP for the ayacut in Karimnagar and Warangal on Wednesday and Laxmi and Saraswati canals for Nizamabad and Adilabad earlier. Below SRSP, the Yellampalli project was almost getting filled. It received about 24,000 cusecs from Kadam and Swarna reservoirs, the latter a medium project, and its own catchment along the river.
