The Hemrin Dam is a dam on the Diyala River 100 km northeast of Baghdad, Iraq. The main purpose of the dam is flood control, irrigation and hydroelectric generation. Its power station has a 50 MW capacity. The dam and the attached power house were built in years 1976-1981 by the then Yugoslav company GIK Hidrogradnja (of Sarajevo, now Bosnia-Herzegovina). All the equipment (gates, turbines, generators) were also supplied by the then-Yugoslav companies.[1]
A large archaeological salvage operation was undertaken to excavate archaeological sites that were at risk of flooding once the reservoir (now Hamrin Lake) would start to fill. Sites that were excavated as part of this operation included Tell Madhur, Tell Rashid, Tell Saadiya, Tell Yelkhi, and Tell Abada.[2]
