Mamloo Dam (Persian: سد ماملو), is a dam in the Central Alborz mountain range of northern Iran near to the Mount Damavand.The reservoir created by the dam has a capacity of about 250 million cubic meters and [1] It has been built to meet the needs of agricultural water in Varamin plain, but due to the drinking water supply in Tehran, a limited amount of stored water is supplied to the plain. One of the most important effects of the insufficient supply of surface water in Varamin plain is the reduction of groundwater aquifers and land subsidence[2]
It is located east of Tehran and southeast of Mount Damavand.
