The southwest monsoon sets in by mid June and lasts till September. The maximum rainfall is normally recorded in the months of July and August. The mean annual rainfall is reported to be 2500 mm.

The average water depth is reported to be 12 m with a gross storage at Full Supply Level (FSL) of 2294 million gallons, out of which 4 million gallons per day are supplied to Greater Mumbai http://grassrootsresearch.org/papersandarticles/sweden%20paper.pdf A design for echo sustainability: lessons from a stressed environment in Mumbai] .The highest overflow level, recorded at the dam is 139.17 m (456.6 ft).This fresh water lake primarily fulfills the water requirement of the southern part of Mumbai.
