Environmental Management Plan and Quality Protection Program for Water Resources of Narmab Dam Basin

About Project

Construction of Narmab Dam is one of the most important projects in the east of Golestan Province. This dam is aimed at flood controlling and runoff storing, developing and improving agricultural lands, supplying drinking and industrial water, regulating, balancing and providing water needs of downstream lands, proper use of groundwater resources and its integration with surface water and tourism development. In order to planning and further studies on construction of this dam, Regional Water Company of Golestan put it in its priorities to investigate qualitative status of the water resources and the catchment basin of the Narmab Dam, so that according to the results obtained, the Environmental Management Plan was completed and presented.
