Mumbai Lake Levels Reach 94.15 Per Cent Capacity Following Fresh Inflows
Water stock across the seven reservoirs supplying Mumbai climbed to 94.15 per cent of total useful live storage capacity as of 6 am on Wednesday, August 19. The storage level rose from 93.80 per cent recorded the previous day, marking a 24-hour gain of 0.35 percentage points following continuous monsoon inflows.
According to the daily lake-level report released by the Hydraulic Engineer’s Department, the seven lakes collectively held 13,62,624 million litres (ML) of useful water stock out of their total capacity of 14,47,363 ML. The sustained storage levels have significantly strengthened the city's water-supply buffer for the coming months.
Three of the seven supplying reservoirs are currently at full capacity. Modak Sagar, Tulsi, and Vehar are all standing at 100 per cent useful live storage. Tansa is also nearing full capacity, recorded at 99.06 per cent.
Among the other key water sources, Middle Vaitarna has reached 94.79 per cent of its live storage capacity. Bhatsa, which serves as Mumbai's largest single water source, holds 6,73,963 ML, placing it at 93.99 per cent capacity. Upper Vaitarna holds 1,96,840 ML of useful storage, representing 86.70 per cent of its total capacity.
The catchment areas of the lakes recorded varying amounts of rainfall over the 24-hour monitoring period leading up to Wednesday morning. Upper Vaitarna recorded the highest precipitation with 39 mm of rain. Vehar received 10 mm, Tulsi received 8 mm, and Bhatsa recorded 6 mm. Middle Vaitarna logged 5 mm of rainfall, while Modak Sagar and Tansa recorded 4 mm each.
Several reservoirs reached their overflow thresholds earlier in the season. Vehar and Tulsi both began overflowing on July 7. Tansa followed by overflowing on July 22, and Modak Sagar reached its overflow mark on July 23.
The Hydraulic Engineer's Department report also confirmed past operational adjustments at the dams, noting that the Middle Vaitarna WSCPO gate was closed on June 6, while water discharge from Upper Vaitarna was halted on July 7.
