Iran’s president has warned that the capital is facing an unprecedented water and energy crisis as reservoirs have plunged to historic lows, threatening supplies of drinking water and electricity generation. … The city has entered its sixth consecutive year of drought, with some dams at less than 10% of capacity. Officials say that in the east of Tehran, the Latyan Dam — one of five key reservoirs — is only about 9% full. … Experts say the link between water availability and electricity generation has become increasingly evident, as hydropower output drops and thermal plants struggle with cooling shortages.
