Iran Faces Looming Crisis as Water Reserves Dwindle: Urgent Measures Needed!
Iran is currently facing a critical water crisis as its key reservoirs are reaching alarmingly low levels. This situation stems from years of declining rainfall and an over-reliance on hydropower, raising significant concerns about water availability across the nation. A senior water official, Isa Bozorgzadeh, has provided alarming insights into the current state of Iran’s water resources.
On Tuesday, Bozorgzadeh, who serves as the spokesman for Iran’s water industry, disclosed that the usable capacity of the Karaj Dam, located near Tehran, has plummeted to nearly 50%. A significant portion of this water is rendered unusable due to sediment accumulation. He further emphasized the dire situation by stating:
“Lar Dam has practically dried up, and Latian, Taleqan, and Mamloo reservoirs are facing a 46% decrease in rainfall compared to the average and 25% compared to last year.”
This alarming decline in water levels has sparked growing apprehension, especially in the provinces of Tehran and Isfahan, where authorities are contemplating the possibility of water rationing. Bozorgzadeh noted that Tehran’s demand for surface water has reached a staggering 50 million cubic meters each month, while the total reserves from the capital’s five main dams, including dead storage and sediment, stand at only 60 million cubic meters. He remarked:
“Conditions have deteriorated to the point where even a motorcyclist could drive through the reservoirs.”
Recent reports from the Eastern Tehran water and wastewater company reveal that:
- Latian Dam is only 12% full.
- Mamloo Dam is similarly at 12% capacity.
- Lar Dam has dwindled to just 1% full.
- Karaj Dam, which was once a reliable source, has now shrunk to 7% capacity.
Iran’s water supply system heavily relies on rainfall, snowmelt, and underground aquifers. However, decades of excessive groundwater extraction have severely depleted these vital aquifers. The recent sharp decline in precipitation — over 40% in Tehran province when compared to long-term averages — has exacerbated this critical issue.
Bozorgzadeh also highlighted additional regions facing similar challenges, including:
- Hormozgan
- Sistan and Baluchestan
- Khuzestan
- Kohgiluyeh and Boyer-Ahmad
- Bushehr
These areas have reported a dramatic 50% drop in rainfall, further stressing the already strained water resources. Government spokeswoman Fatemeh Mohajerani acknowledged the gravity of the situation, stating:
“A nationwide decrease in average rainfall this year has led to shortfalls as high as 75% in some provinces.”
Despite the significant reduction in rainfall, Iran’s energy ministry reports indicate that hydropower generation has increased by 24% since the fiscal year beginning in March 2023. This surge in production occurred amidst the nation’s ongoing energy crisis, with hydropower generation reaching 17 terawatt-hours and maintaining that level into the current year. However, this increase raises questions about the sustainability of Iran’s energy strategy.
Dalga Khatinoglu, an oil and gas analyst, pointed out that the government’s focus on maintaining high hydropower output contributed to the current crisis. He stated:
“Iran failed to achieve its planned growth in thermal and renewable energy, leaving it dependent on hydropower.”
Over the past two years, the country has commissioned only 4 gigawatts of new power plants, which represents about 30% of its target, with 90% of the output being gas-fired and the remainder from renewable sources. This heavy dependence on hydropower, coupled with ongoing drought conditions, has accelerated the depletion of Iran’s reservoirs, leaving scant room for recovery even if rainfall levels were to improve.
Moreover, Iranian media outlets have started to raise alarms regarding the broader implications of this crisis. Etemad newspaper has warned that 2025 could be a pivotal year for Iran’s water and energy challenges, suggesting that shortages could become more severe than anything previously encountered. Some hydrologists have even cautioned that Iran has exhausted nearly 1,000 years’ worth of groundwater reserves within just three decades, highlighting the urgency of addressing this looming crisis.
In conclusion, the situation in Iran serves as a stark reminder of the importance of sustainable water management and the need for immediate action to mitigate the ongoing water and energy crisis. As the country grapples with these challenges, the focus must shift towards innovative solutions and efficient resource management to secure a sustainable future for its population.
