Mumbai Rains: City's 7 Lakes 81.47% Full Amid Light Showers; Bhatsa Holds Highest Volume Of Water Stock

Mumbai: The city’s water stock levels have surged significantly, with collective lake reserves reaching 81.47 per cent of the total required supply, according to the Hydraulic Engineer's Department report on Friday. The total water available across all seven reservoirs stands at 11,79,147 million litres (ML), offering much-needed relief amidst monsoon fluctuations.

Bhatsa Holding Highest Volume Of Water Stock

Among the lakes, Bhatsa currently holds the highest volume of usable water at 5,46,394 ML, contributing nearly half of the total reserves. It saw a 0.20 metre rise in level over the last 24 hours and has recorded a total rainfall of 1,474.00 mm this monsoon.

Modak Sagar began overflowing on July 9 at 6:27 am, following steady rainfall in its catchment area. Its current level is 163.14 metres, marginally below its full capacity of 163.15 metres, with 1.00 mm of rainfall recorded today. It contributes 1,28,910 ML to Mumbai's supply, nearly 100 per cent of its live storage capacity.

Middle Vaitarna, which had its gates opened on July 7 at 1:15 pm, has risen by 0.18 metres in the past 24 hours and currently holds 1,78,885 ML, about 92.43 per cent of its live storage. Tansa, meanwhile, saw a modest 0.05-metre rise, contributing 1,32,074 ML (91.04 per cent full), with 0.00 mm of rainfall recorded today but a total of 1,551.00 mm for the season.

The Upper Vaitarna reservoir stands at 601.87 metres, just shy of its full level of 603.51 metres. It holds 1,74,007 ML, which is about 76.64 per cent of its live storage. The lake recorded 0.00 mm rainfall today but has seen 1,097.00 mm overall this monsoon. Water release from this lake began on July 5 at 4:30 pm.

On the lower end, Vihar and Tulsi reservoirs are relatively full but contribute less to the total volume due to their smaller size. Vihar, with a level of 77.81 metres, holds 15,894 ML (52.58 per cent), while Tulsi, at 136.92 metres, holds 6,880 ML, around 85.51 per cent of its live storage.

The total rainfall across all catchment areas for the current season stands at 828.00 mm, as reported from the Bhandup Complex. As of now, Mumbai’s water security appears stable, with reservoirs filling up well ahead of critical depletion levels. Further rainfall in the coming weeks is expected to take overall storage closer to 100 per cent capacity.
