India is entering the winter season with mounting water security concerns following a 12.56% monsoon rainfall deficit during June–September 2026, declining reservoir reserves and persistent groundwater depletion. According to the Central Water Commission, 178 monitored reservoirs held 132.734 billion cubic metres of water, below the 10-year average of 151.118 billion cubic metres. A strengthening El Niño, which could influence rainfall patterns into early 2027, adds uncertainty to the outlook, particularly as irrigation demand rises for rabi crops and reservoir inflows decline during winter. The Central Ground Water Board’s 2025 assessment estimated annual groundwater extraction at 247.22 billion cubic metres, equivalent to 60.63% of annual extractable resources, while 730 assessment units were classified as over-exploited. Regional concerns have emerged in drought-prone Maharashtra and Telangana, where depleted local water sources and falling reservoir levels are increasing pressure on supplies. Although El Niño does not guarantee a deficient future monsoon, the combination of limited reserves, stressed aquifers and rising demand could intensify shortages in vulnerable regions ahead of summer 2027. The situation underscores the need for stronger reservoir management, groundwater recharge, efficient irrigation, leakage reduction, wastewater reuse and equitable allocation of available supplies to strengthen India’s resilience against climate variability.
