Flood warnings issued as Himayat Sagar inflows peak at 17,500 cusecs

Hyderabad: Heavy rainfall in catchment areas triggered massive inflows into Himayat Sagar on Thursday, peaking at 17,500 cusecs by 9 a.m., prompting the Hyderabad Metropolitan Water Supply and Sewerage Board (HMWSSB) to issue two successive flood warnings and lift eight of its 17 gates.

At 6:30 a.m., the reservoir was receiving 700 cusecs, rising to 17,000 cusecs by 7:30 a.m. and 17,500 cusecs by 9 a.m. The released floodwater is flowing into the Musi River. Inflows are sourced from upstream villages in the Gandipet catchment such as Chevella, Vikarabad, Shankarpally, Mominpally, and Dobi Peta. The Esi River, fed by rainfall in Andapur, Kotwal Peta, Narkuda, Tandur, and Moinabad, also contributes to Himayat Sagar’s volume.

Eight floodgates opened at Himayat Sagar after massive inflows

At 9 a.m., Himayat Sagar stood at 1,762.40 feet (against a full tank level of 1,763.50 ft), holding 2.678 TMC of water. Outflow was 7,926 cusecs through eight gates opened to a height of three feet. Osman Sagar, closely linked to Himayat Sagar, recorded inflows of 3,000 cusecs, with its water level at 1,785.30 feet (2.885 TMC) against a full level of 1,790 feet.
