Zayanderud Dam, also spelled Zayandeh Rud Dam formerly known as the Shah Abbas Dam, is an arch dam on the Zayandeh River about 10 km (6.2 mi) east of Chadegan, Iran. The Zayanderud Dam is the main water reservoir with 1450 MCM capacity and has been exploited since 1971. The Zayanderud has provided the needs of water for important economic activities including agricultural, industrial and domestic consumptions. The primary purpose of the dam is water supply to Isfahan which lies 88 km (55 mi) to the east. It also supports a power station with an installed capacity of 55 MW.^[1]^[2] In recent years, the Zayandeh River has experienced significant reductions in flow due to a combination of drought, climate change, and overuse of water resources.
