The Silveh Dam (Persian: سد سیلوه) is an earth-fill embankment dam on the Lavin River just downstream of the village of Silveh in Piranshahr County, West Azerbaijan Province, Iran.

Since completion, a tunnel and canals shift water from the reservoir north to the Chaparabad area.

[citation needed] Construction on the dam began in 2004 and it was expected to be complete by the end of 2015.

Near the northeastern edge of the reservoir water will be able to enter a 841 m (2,759 ft) long tunnel which will discharge it into the opposing valley, within the Lake Urmia basin.

About 121,700,000 m3 (98,700 acre⋅ft) of water will be transferred through the tunnel annually while an estimated 10,800,000 m3 (8,800 acre⋅ft) will be sent downstream to Piranshahr during the same period.
