Gavshan Dam (fa|سد گاوشان) is an embankment dam on the Gaveh River 400NaN0 south of Sanandaj in Kurdistan province, Iran. It was created for the primary purpose of irrigation but also supports an 11 MW hydroelectric power station.

About 1890000000NaN0 can be transferred annually for the irrigation of 310km2. Additionally, water from the reservoir is used to provide drinking water for the city of Kermanshah in the amount of 630000000NaN0 annually. Construction on the dam began in 1992 and was completed in 2004.[2] It was inaugurated by Iran's President Mohammad Khatami on 13 February 2005.[3]
