Article summary
As of early June 2026, 106 of India's major reservoirs are storing less than 40% of their live storage capacity, coinciding with IMD's forecast that the 2026 southwest monsoon rainfall will be approximately 10% below normal, partly attributed to El Niño conditions in the Pacific Ocean. India's 150 major reservoirs monitored by the Central Water Commission (CWC) are critical lifelines for irrigation, drinking water, and hydropower generation, collectively accounting for a significant share of the country's total live storage capacity. El Niño — a periodic warming of central and eastern Pacific Ocean surface temperatures — historically suppresses Indian monsoon rainfall by disrupting the moisture-laden winds that travel from the Arabian Sea and Bay of Bengal toward the subcontinent. A deficient monsoon compounds existing water stress, threatening kharif crop sowing, raising food inflation risks, and increasing dependence on groundwater, which is already over-exploited in many states. For India, where nearly 50% of net sown area remains rain-fed, a below-normal monsoon has cascading implications for agricultural output, rural livelihoods, and macroeconomic stability.
What this tests
Sample questions — answers revealed after test
Q1. The Central Water Commission (CWC) monitors 150 major reservoirs in India. What is the approximate total live storage capacity of these reservoirs, and what share of India's total estimated live storage capacity does it represent?
Q2. In June 2026, the India Meteorological Department (IMD) forecasts monsoon rainfall at 85% of the Long Period Average (LPA). Simultaneously, 106 of 150 CWC-monitored reservoirs are below 40% of their live storage capacity. Which of the following assessments most accurately applies the relevant definitional and institutional frameworks to this scenario?
Q3. Consider the following statements regarding India's water-food-energy nexus under a deficient monsoon scenario: 1. A below-normal southwest monsoon affects only rain-fed agricultural areas; irrigated areas drawing from major reservoirs remain insulated from rainfall variability. 2. El Niño is associated with suppression of the Indian southwest monsoon because warm sea surface temperature anomalies in the central-eastern Pacific weaken the Walker Circulation, reducing moisture flux towards the Indian subcontinent. 3. IMD's Long Period Average (LPA) for the southwest monsoon season is 87 cm, computed from rainfall data spanning 1971–2020. 4. A deficient monsoon year invariably leads to a below-normal hydropower generation, as most of India's hydropower capacity is run-of-river and independent of reservoir storage levels. Which of the statements given above are correct?
