Mumbai Lake Levels Reach 95.72% as Seven Reservoirs Hold 13.85 Lakh ML

Mumbai's seven supply reservoirs recorded a marginal rise in their combined water stock, with live storage reaching 95.72 per cent as of 6 am on Tuesday, August 25, 2026. The water stock increased from 95.53 per cent recorded the previous day, strengthening the city's water security.

According to the latest report from the Hydraulic Engineer's Department, the seven lakes collectively hold 13,85,447 million litres (ML) of water against their total useful capacity of 14,47,363 ML. Over the past 24 hours, the total stock increased by approximately 2,823 ML.

Among the reservoirs, Modak Sagar and Vehar continue to sit at 100 per cent of their useful storage capacity, holding 1,28,925 ML and 27,698 ML respectively. Tansa stands at 99.10 per cent with 1,43,769 ML, while Tulsi holds 7,961 ML at 98.94 per cent capacity.

Middle Vaitarna has reached 96.48 per cent capacity with 1,86,722 ML in storage. Bhatsa, which serves as Mumbai's largest single source of water, holds 6,86,583 ML at 95.75 per cent capacity. Upper Vaitarna recorded the lowest storage level among the seven reservoirs at 89.76 per cent, with 2,03,789 ML of useful water content.

Rainfall over the 24-hour period contributed to the gains across catchment zones. Middle Vaitarna recorded 15 mm of rain, Upper Vaitarna received 5 mm, Tulsi logged 4 mm, while Modak Sagar and Tansa recorded 3 mm each. Vehar received 2 mm of rain, while Bhatsa recorded no rainfall during the period. At the Bhandup Complex, 5 mm of rainfall was recorded on Tuesday, taking its total seasonal rainfall to 2,699 mm.

Several reservoirs continue to maintain their overflow status after reaching capacity earlier in the season. Vehar and Tulsi began overflowing on July 7, followed by Tansa on July 22 and Modak Sagar on July 23. The steady levels keep the city's overall reservoir storage comfortably above the 95 per cent threshold.
