The lake has a water spread area of 220 hectares (540 acres) and is a “seasonally recharged body of water formed over a tectonic depression on the leeward flank of the Talesh (Alborz) Mountains in North West Iran”. It is formed of two lakes, one small and another large, which merge during the rainy season when the depth of the lake is 5.5 meters (18 Ft.). The average depth of the lake is about 3 meters (9.8 Ft.). Heavy siltation has occurred in the lake due to high rainfall incidence, irrigation releases, the physio-chemical reactions, and slope gradient of less than 35%, causing erosion; these factors have resulted in a tropic state of the lake.
The lake contains fish species of rainbow trout; fingerlings were introduced with the objective of practicing commercial and sports fishing. Fingerlings are introduced into the lake every year to promote fishery practices. The fish feed on the Gammarus fasciatus found in the lake bed and grow into robust pink-colored fish. Among the fauna species found in the lake area are ruddy she ducks, and swallows which are the migrant species.
