Evan Lake is a small alpine lake in Alamut region of Arburz range, in Qazvin province of Iran.
The only tributary that flows into the lake is a stream with the same name, Evan, coming down from northern mounts. The north of the lake is also surrounded by three small villages, namely from east to west: Varbon, Evan and Zar-abaad.
Because of the heavy seasonal rainfall and snowfall in the winters, which at times reaches a few meters, it has numerous water resources. Surrounded by Avan, Varbon, Zavardasht and Zar-abaad villages, the lake is located in an altitude of 1800 meters above sea level, its maximum length is 325 meters, and it has a width of 275 meters.
The deepest section of the lake is 7.5 meters and extends over 70,000 square meters. The water of Evan Lake is provided from rainwater and also the ever-gushing springs in its ground which results in very clean and transparent clear water. The excess water of the lake which is actually overflowed of this lake forms a small river which irrigates farmlands in the villages of Kushk and Ain. Most residents of these two villages either breed livestock or work their land.
Evan Lake is suitable for fishing, swimming and riding boats in summer while in fall it hosts migratory birds such as swan, goose and duck. In winter, the lake can be used for sports such as skiing and ice skating while its surface becomes slippery with ice in winter.
