Narmab Dam

Narmab Dam, located in the Chehel Chai area of Minudasht County in Golestan Province, is under construction on the Narmab River and will be the largest dam in the province. Construction began in 2011 (1390 SH). The dam is intended to supply drinking and irrigation water, control floods, replenish groundwater aquifers, generate hydroelectric power and develop tourism in eastern Golestan.

The dam is designed with a large storage capacity, equal to the combined water storage of Golestan's three major dams: Boustan, Golestan and Voshmgir. It can meet the vital needs of a large share of the province's population and farmland. Through this dam, 550,000 residents of eastern Golestan Province will have access to a stable supply of drinking water, and 18,000 hectares of the region's farmland will also benefit from its water.

Another important benefit of the Narmab Chehel Chai Dam is flood control in the downstream areas of the rivers, especially given Golestan's history of severe and destructive floods. The dam is considered one of the key infrastructure projects for the sustainable development of eastern Golestan Province. With proper management and operation, it can have many positive effects on the environment, farmers' livelihoods and the region's water supply.
