Mumbai Lake Levels Reach 95.94 Per Cent Capacity Across Seven Reservoirs
Water stock across the seven reservoirs supplying Mumbai rose to 95.94 per cent as of 6 am on Thursday, September 3, according to the latest report released by the Hydraulic Engineer’s Department. The figure represents an increase from the 95.83 per cent recorded the previous day, marking a rise of 0.11 percentage points following steady rainfall in the catchment zones.
The city’s lake system currently holds 13,88,542 million litres (ML) of useful water against a total live storage capacity of 14,47,363 ML. Among the individual water bodies, both Modak Sagar and Vehar have reached 100 per cent of their useful storage capacity. Modak Sagar holds 1,28,925 ML of water, while Vehar contains 27,698 ML.
Water levels across the other supplying reservoirs also remain high. Tansa is filled to 98.29 per cent of capacity with 1,42,592 ML of useful water, while Middle Vaitarna stands at 97.74 per cent, holding 1,89,161 ML. Bhatsa, a primary contributor to Mumbai’s daily water supply, has reached 96.06 per cent with 6,88,778 ML of water. Tulsi stands at 97.20 per cent capacity, and Upper Vaitarna holds 90.19 per cent of its capacity.
The report also documented measurable rainfall across all lake catchments during the preceding 24-hour period. Bhatsa recorded the heaviest precipitation at 41 mm, followed by Middle Vaitarna with 12 mm. Upper Vaitarna, Vehar, and Tulsi each recorded 11 mm of rainfall, while Tansa received 8 mm and Modak Sagar logged 7 mm.
Combined useful water storage across Upper Vaitarna, Tansa, and Middle Vaitarna reached 6,64,245 ML, representing 95.63 per cent of their aggregate live storage capacity. Several lakes overflowed earlier in the monsoon season, starting with Vehar and Tulsi on July 7, followed by Tansa on July 22 and Modak Sagar on July 23. Operational adjustments made earlier in the season included closing the Middle Vaitarna W.S.C.P.O gate on July 6 and halting water discharge from Upper Vaitarna on the same day.
The accumulated reserves establish a strong water supply buffer for the city as the monsoon progresses. Civic authorities confirmed they are continuing to track reservoir levels and incoming precipitation daily.
