Narmashir Storage Dam

Location

Narmashir Storage Dam is located in Kerman Province in 80 km south of the city of Bam in Anjirak Village (between the longitude 57° and 58' up to 58° and 40' and latitude 28° and 30' up to 28° and 39').

History

The hydro-potential studies of the river Nesa were commenced by Mahab Ghodss Consulting Engineering Co. in 1984. The reconnaissance reports presented by the consultant introduced axis 1, which is located in close proximity to the Village Anjirak, as the best technical/ economical alternative amongst the 4 points already considered on the River Nesa. Eventually, the client agreed upon the construction of a concrete face rock fill dam.

Objectives

The main objectives of Narmashir Storage Dam are to supply the water right of the downstream area through trickle and hydro-flume irrigations, supply drinking water for the cities Bam and the surrounding villages, flood control and job creation.
