Mumbai Rains: City's Water Stock Crosses 37% As Consistent Showers Boost Lake Levels
Mumbai: Mumbai’s water stock situation has improved with continued monsoon showers boosting lake levels across the city’s reservoirs. As per the latest data released by the Hydraulic Engineer’s Department at 6:00 am on Thursday, June 27, 2025, the total water stock in Mumbai's lakes has reached 5,37,788 million litres, which is approximately 37.16 per cent of the required 14.47 lakh million litres.
The increase follows consistent rainfall in catchment areas over the past few days. On Thursday alone, the Bhandup Complex recorded 8 mm of rain, taking the season’s cumulative rainfall there to 459 mm. Most major reservoirs showed either a steady rise or consistent levels with positive storage gains.
Details On Rise In Lake Levels
Bhatsa Lake, Mumbai’s largest contributor to the drinking water supply, rose by 0.50 metres in the past 24 hours and currently holds 2,19,650 million litres of usable content. The lake received 23 mm of rainfall on Wednesday, bringing its seasonal total to 719 mm. Its steady inflow has made it the single largest water source for the city at present.
Upper Vaitarna recorded a modest rise of 0.22 metres, now holding 99,977 million litres of useful content, with a live storage of 44.03 per cent. The catchment saw 23 mm of rainfall in the last 24 hours, contributing to a seasonal accumulation of 411 mm.
Modak Sagar, despite a slight drop of 0.06 metres, continues to contribute with 69,323 million litres of water. It has received the highest cumulative rainfall this season at 788 mm, although Thursday’s rainfall was limited to 23 mm. Middle Vaitarna, another crucial lake, showed a healthy increase of 0.70 metres, storing 75,788 million litres of water after recording 42 mm of rainfall in a day.
Tansa and Vihar lakes also reported incremental gains, while Tulsi remained stable with minimal change but has crossed 722 mm in total rainfall for the season. These gains come at a crucial time, ensuring that Mumbai’s water supply remains stable in the weeks ahead.
Meanwhile, as the city sees a consistent rise in water stock levels, nearly 63 per cent of the annual water stock is still to be filled, hence, judicious use of water is essential. With forecasts of further monsoon activity in the coming days, reservoir levels are expected to rise further, offering more relief to the city.
