The water storage levels in Iran’s dams have plummeted dramatically, raising significant concerns about water supply sustainability. If the current decrease in rainfall is not mitigated by the end of winter, the water crisis could escalate, exacerbating the “big deficit” that Iran’s Minister of Energy has openly described as a potential catastrophe.
Dire Water Storage Statistics
Official reports reveal alarming figures: as of January 12, 2025, six dams have less than 10% water storage, while the overall reservoir capacity stands at just 44%. This decline highlights the persistent inefficiency in managing Iran’s energy and water resources. While summer electricity shortages have become a recurring issue, experts now warn of an impending water shortage that could make the upcoming summer particularly challenging.
Energy and Environmental Crises
This winter, Iran has faced a trifecta of crises: shortages in gas and electricity, compounded by severe air pollution. Such challenges underline the increasing likelihood of energy supply problems becoming a permanent crisis for the country. Energy Minister Abbas Aliabadi recently referred to the potential for severe water and electricity shortages in the summer as a “big deficit,” expressing hope that such dire circumstances can be avoided.
Rainfall Deficit and Rising Water Stress
Since the beginning of the water year in late September, rainfall has decreased by 33%, making the water crisis even harder to address than electricity shortages. The regime’s president has labeled the water consumption situation as a “disaster.” Alarmingly, all provinces, except Gilan, Mazandaran, and Khorasan-Razavi, have reported rainfall deficits ranging from 1% to 88%. In Tehran’s metropolitan region, dam levels are critically low, with reservoirs averaging just 19% capacity.
Insufficient Reservoir Input and Rising Output
The water year, which spans from September 22 to the following September 21, has so far seen a 3% decline in total water input into reservoirs compared to the previous year. As of January 12, 2025, only 5.67 billion cubic meters of water have flowed into reservoirs, down from 5.86 billion cubic meters in the same period last year. Compounding the issue, dam outputs have risen by 4%, exacerbating the imbalance between supply and demand.
Impending Drought
With only two months remaining until the dry season, the outlook is grim. Historical rainfall patterns suggest that only two or three significant rain events might occur before summer, insufficient to bridge the water deficit. If rainfall remains below consumption levels, Iran risks entering a “gradual drought,” potentially evolving into a “persistent drought” with severe consequences for agriculture and water availability.
Climate Change and Mismanagement
Climate change has intensified Iran’s water challenges. The country frequently experiences torrential spring rains, which, without adequate infrastructure to manage and store the water, often lead to destructive flooding. This failure to harness such rainfall has further strained water resources and heightened public dissatisfaction.
Agricultural Impacts
Agriculture accounts for 85% to 90% of Iran’s water consumption, making it especially vulnerable to shortages. A water deficit in the summer could disrupt agricultural production, driving up food prices and exacerbating economic hardships. Experts also predict that water scarcity will contribute to increased air pollution, particularly dust storms originating from degraded ecosystems such as the Gavkhouni Lagoon, Hawizeh Marshes, and Lake Urmia.
A Hard Summer Ahead
Experts anticipate that the coming summer will be exceptionally challenging for Iran’s energy supply and environmental conditions. Dust phenomena, traditionally confined to western regions, are expected to spread to northwestern and central areas. The repercussions of Iran’s water crisis are likely to ripple across multiple sectors, emphasizing the urgent need for sustainable resource management and climate adaptation strategies.
