Mumbai Water Stock – Mumbai’s water security has received a major boost as combined useful water stock across the city’s seven supplying reservoirs rose to 95.95% of total capacity. According to early morning data from the BMC’s Hydraulic Engineer’s Department, the seven lakes collectively hold 13,88,785 million litres (ML) out of a maximum live capacity of 14,47,363 ML. The marginal daily rise from 95.87% ensures a robust water buffer as the city heads into the autumn months.
Mumbai Water Stock – Vehar and Modak Sagar Near Complete Capacity
Individual reservoir breakdown indicates near-maximum capacity across several key catchments. Vehar reservoir stands at 100% capacity, while Modak Sagar is virtually full at 99.99%. Tansa registered 98.37% storage, Tulsi holds 98.12%, and Middle Vaitarna maintains 97.95% useful content. Bhatsa, the largest single supplier to Mumbai, recorded 95.98% capacity, providing strong supply assurance across urban zones.
Mumbai Water Stock – Upper Vaitarna Lagging Slightly Behind Comparative Trends
While overall lake levels remain extremely healthy, Upper Vaitarna continues to trail other catchments, currently standing at 89.76% of its live capacity. Aggregate water levels remain marginally lower than the 96.51% recorded during the same period in 2025, but slightly higher than the 95.75% stock logged in 2024. Civic officials noted that sustained, moderate catchment rainfall continues to stabilize levels across all seven dams.
Mumbai Water Stock – Steady Catchment Inflows Ensure Stable City Supply
With key lakes having overflowed earlier in the monsoon season, the current water reserves comfortably position Mumbai to meet daily municipal demands without immediate supply cuts. The Hydraulic Engineer’s Department will continue daily monitoring at the Bhandup Master Control Centre to track inflows and optimize distribution networks as monsoon activity moderates.
