Overview
- The seven lakes that supply Mumbai rose to about 49.8% of live storage in mid‑July, with combined usable stock near 7.22 lakh million litres according to the Bhandup master control reports.
- Vihar and Tulsi reached full capacity and began overflowing on July 7, prompting authorities to monitor releases and close the Middle Vaitarna WSCPO gate on July 6.
- Morbe Dam in Navi Mumbai climbed from roughly 8.8% usable at the end of June to about 42.8% usable by early July, giving NMMC officials an estimate of roughly 166 days of supply at current consumption rates.
- Operational moves included stopping releases from Upper Vaitarna on July 6 and closing specific gates to conserve storage as lakes rose and some began to overflow.
- Officials say the rainfall-driven recovery eases immediate supply stress but urge continued water conservation because future monsoon rainfall remains uncertain.
