As no monsoon rains witnessed since Thursday evening, the inflows from catchment areas into Himayat Sagar and Osman Sagar has decreased significantly in the last two days. This has helped the authorities to keep lowered the crest gates but for atleast a foot height thereby to continue releasing the surplus water into Musi River as and when the lakes received the inflows.
As against the 400 cusecs of inflows being recorded few days ago, the reservoir is receiving only 200 cusecs of inflows since Thursday while the supervising officials of Hyderabad Metropolitan Water Supply and Sewerage Board (HMWSSB) are releasing 208 cusecs of water into Musi River to release the burden over the reservoir.
As per the official statistics, the water level at Osman Sagar Lake remained stood at 1786.30 feet (3.071 TMC) as against the full Tank level of 1790.00 feet (3.900 TMC) with two gates are remained opened up to a feet height to feed Musi River with surplus water. As the inflows simmered down during the last two days the authorities, supervising the reservoir, lowered down the crest gates from two to only a foot.
Similarly, the Himayat Sagar Lake too is witnessing low inflows from the catchment area much before the Osman Sagar Lake. As per official records, the Himayat Sagar Lake is presently receiving a mere 150 cusecs of inflows since Thursday as against the 200 cusecs of inrush being recorded last week. However, to avoid the pressure on the Lake, the authorities are releasing 170 cusecs of water into Musi River by keeping one gate remain open up to a mere 0.6 feet height.
Following two days of calm from showers, the water level at Himayat Sagar reservoir remained standing at 1760.65 feet (2.385 TMC) as against the full tank level of 1763.50 feet (2.970 TMC).
According to sources, the HMWSSB authorities, supervising both the historic reservoirs, are keeping an eye over the water levels regularly and are releasing the pressure as and when the inflows are swelling up in the Lakes through pulling up and down the crest gates.
