Data issued by the Central Water Commission (CWC) on March 20 shows that India’s major water reservoirs capacity has reduced by 45%, highlighting a concerning trend in water availability. The amount of live storage in 155 large reservoirs was 80.7 billion cubic meters (BCM), which is far less than the 180.8 BCM overall live storage capacity.

Nagaland, Punjab, Chhattisgarh, Bihar, Uttarakhand, Odisha, Jharkhand, and Himachal Pradesh were among the states that recorded lower storage levels than at the same time last year. Just 25% of the total capacity was reported by the northern area, which is made up of 11 reservoirs spread throughout Punjab, Himachal Pradesh, and Rajasthan. Significant shortages were seen in Punjab and Himachal Pradesh, where storage levels were 45% and 36% below average, respectively.

Reservoirs in the southern region—which include Kerala, Telangana, Tamil Nadu, Andhra Pradesh, and Karnataka—held only 41% of their entire live capacity, resulting in the second-lowest water levels. As opposed to this, storage levels in the eastern, central, and western reservoirs were 44%, 49%, and 55%, respectively.

Effects on Water Supply and Agriculture

Concerns over water scarcity are growing as the India Meteorological Department forecasts above-normal heatwave days from March to May. Summer crops planted between the Rabi and Kharif seasons may see lower yields due to the monsoon’s delayed arrival, which is still more than two months away.

According to the CWC statistics, storage levels were below 50% in 14 out of 20 major river basins. Compared to the Godavari, Narmada, and Krishna river basins, which recorded storage levels of 48%, 47%, and 34%, respectively, the Ganga river basin was at 50% of its potential.

Low reservoir water levels, including hydropower production, drinking water supply, and agriculture impact numerous industries. India’s major water reservoirs capacity reduced by 45%, which could lead to severe consequences for agricultural productivity, energy generation, and rural livelihoods. Reduced productivity in agriculture, which mainly depends on river-fed irrigation, might exacerbate rural economic challenges.

Broader Socio-Economic Consequences

The river systems of India are vital for supplying water for home, drinking, and agricultural purposes, as well as for facilitating transportation and the production of power. Millions of people whose livelihoods depend on rivers could face socioeconomic difficulties if reservoir storage significantly declines.

Water conservation initiatives and effective resource management will be crucial as temperatures rise and heatwaves become more intense. The water problem could worsen if there isn’t enough rainfall in the upcoming months, which would have serious repercussions for urban water supplies and agricultural and general economic stability.
