Due to the monsoon rains in Mumbai so far this season, the water in the state's lakes has increased by more than 90 percent, but it is still less than the last two years.However, it is expected that the level of lakes may improve with the forecast of rain in the coming week.The lakes should be 100 percent full by the end of September for an uninterrupted water supply till the next monsoon.
Mumbai's seven big lakes - Tansa, Bhatsa, Upper Vaitarna, Midler Vaitarna, Modak Sagar, Tulsi and Vihar have a combined storage capacity of 14.47 lakh million liters.As on Monday, the lakes have 13.35 lakh ml water which is 92 percent of its total capacity.By mid-July, the water reserves in the lakes were less than 18 per cent.Heavy rains at the end of July caused a huge increase in the stock.But dry August could not contribute much to the stock.As it rained this week, the water stock finally touched the 90 percent mark.But the stock is still lower than it was in the past two years.The lakes had 14.16 lakh ml water (97.9%) in 2020 and 14.2 lakh ml water (98.1 per cent) in 2019 as on 6 September.
If the water level of all the lakes is 100% filled by the end of September, the water reserves are sufficient to supply water for the next 10 months.An official of the hydraulic department said, "There is a full month left and the IMD has predicted good rains in the coming week, so we are optimistic."
