Iran is facing a sharp decline in water resources as Iranian dam inflow drops 40 percent since late September. The Energy Ministry announced that dry autumn conditions have severely limited rainfall, cutting water entering the country’s reservoirs almost in half.
The latest report shows that only 1.48 billion cubic meters of water entered Iran’s dams between late September and mid-November. In the same period last year, the figure reached three billion cubic meters. This dramatic reduction highlights the growing impact of seasonal drought and shifting climate patterns across the country.
Meanwhile, the ministry confirmed that around three billion cubic meters of water were released from reservoirs to supply drinking, agricultural, and industrial sectors. This release marks a 26 percent reduction compared to the 4.05 billion cubic meters discharged last year. Authorities noted that they are prioritizing essential uses to prevent shortages in urban and rural areas.
At present, total stored water in the country’s reservoirs stands at 17.12 billion cubic meters. This volume fills only one-third of the overall capacity, leaving 67 percent empty. A year earlier, the figure stood at 22.92 billion cubic meters, signaling a 25 percent decline in total reserves.
Officials from the Ministry of Energy warned that the situation could worsen if rainfall levels remain below average through winter. They stressed that Iranian dam inflow must improve soon to sustain critical water needs in major cities and agricultural zones.
Experts believe that inefficient irrigation systems, excessive groundwater use, and climate change have intensified the country’s water crisis. Environmental analysts are urging swift reforms in water management and stronger public awareness campaigns.
The government has already begun monitoring consumption patterns and promoting projects to modernize irrigation networks. Energy Ministry representatives also plan to coordinate with provincial authorities to regulate water use more efficiently.
If the dry spell continues, Iran may face broader economic and social impacts, particularly in farming communities that depend on steady reservoir supplies. Sustainable policies and improved infrastructure remain crucial to stabilizing Iranian dam inflow and protecting long-term water security.
