Overview

• Combined stock in the seven reservoirs climbed to 81.47% of capacity, holding 1.18 million million litres as of July 18.
• Modak Sagar is full and overflowing while Tansa (91.04%), Middle Vaitarna (92.43%), Upper Vaitarna (76.64%), Bhatsa (76.20%), Vihar (52.58%) and Tulsi (53.62%) report substantial gains.
• An exceptionally early monsoon—its onset on May 27 marked the earliest since 1950—pushed reservoir levels from just over 10% in mid-June to record mid-July stocks.
• BMC and the Hydraulic Engineer’s Department are adjusting dam gate operations and treatment-plant flows to manage flood risk and distribute water to western and eastern suburbs.
• IMD yellow alerts predict continued light to moderate rain, supporting sustained inflows and raising prospects of full reservoir capacity by mid-August.
