Kuhrang-3 Dam, Arch dam in Chaharmahal and Bakhtiari Province, Iran
Kuhrang-3 Dam is an arch dam in Chaharmahal and Bakhtiari Province with a tall curved structure that curves against the water pressure. The dam holds back water in a large reservoir and directs it toward the Zayandeh River through an underground tunnel network.
Construction began in 2011 following decades of water management efforts in the region that started in the 1950s. The dam emerged as part of a long-term strategy to control water flow in this area where water scarcity has been a persistent challenge.
This dam sits within a broader system of water projects that shape how people in the region manage their water resources. The infrastructure reflects the importance of controlling water flow for communities that depend on it for daily life.
The dam can be viewed from several vantage points that allow visitors to see the structure from different angles. The area is best explored on clear days when visibility of the surrounding landscape is at its best.
The construction faced unexpected geological challenges that affected local water springs in the area. These obstacles led engineers to adjust their plans for how much water could be moved through the tunnel system.
