Heavy rainfall in the catchment areas of reservoirs, supplying water to Mumbai, have led to a significant rise in water levels. 

The seven lakes that provide drinking water to Mumbai have 5,83,639 million litres of water or 40.32 per cent of the total capacity of 14,47,363 lakh million litres, according to the Brihanmumbai Municipal Corporation (BMC) on Monday. The water level in the lakes was 17.62 per cent this time last year.
