Karaj Dam

The dam has altered the natural flow of the Karaj River, impacting aquatic habitats and the migratory patterns of fish and other wildlife. Over the decades, sedimentation has reduced the reservoir’s storage capacity. This affects water quality and the dam’s ability to manage floods and generate power efficiently.

Agricultural runoff and untreated wastewater from upstream regions have occasionally affected the water quality in the reservoir, requiring enhanced filtration and monitoring systems. The formation of the lake has led to changes in the local microclimate, including slightly cooler temperatures and increased humidity in nearby areas.
