Mumbai Lake Levels Reach 94.27% of Useful Water Capacity

The combined water stock in the seven lakes supplying Mumbai reached 94.27 per cent of their total useful capacity as of 6 am on Friday, keeping the city's supply position comfortable.

According to data from the Hydraulic Engineer’s Department of the Brihanmumbai Municipal Corporation (BMC), the total useful water content across the seven reservoirs stood at 13,64,385 million litres against a combined capacity of 14,47,363 million litres. The latest figure marked a marginal decline from the 94.29 per cent recorded on Thursday, reflecting steady storage levels alongside ongoing daily consumption.

Three of the reservoirs—Modak Sagar, Vehar, and Tulsi—are currently at 100 per cent useful capacity after overflowing in July following substantial rainfall across their catchment areas. Among the remaining major lakes, Tansa was recorded at 98.77 per cent useful content capacity, while Middle Vaitarna stood at 94.03 per cent.

The Hydraulic Engineer’s Department is actively monitoring reservoir levels and dam operations through its Master Control Centre located at the Bhandup Complex. Civic officials are tracking dam gates and managing water release schedules to regulate inflows and ensure reservoir stability.

Several lakes, including Tansa and Modak Sagar, began overflowing earlier in July amid strong monsoon activity. The sustained rainfall significantly boosted Mumbai's water reserves, establishing a substantial buffer for the city, which relies on the seven lakes for the bulk of its municipal water supply.

Officials stated that they will continue to track rainfall patterns, inflows, and reservoir levels closely as the monsoon season continues.
