Despite heavy rainfall over the past week in the city, the water storage in lakes has risen from 8 per cent to just 25.80 per cent. Reason: sporadic rainfall in Thane and Nashik where a majority of the lakes are situated.

Of the total seven lakes that supply water to the city, Bhatsa, Tansa, Upper Vaitarna, Middle Vaitarna, Modak Sagar are located on Thane-Nashik belt while Tulsi and Vihar are in Sanjay Gandhi National Park (SNGP).
