It is 48 kilometres (30 mi) to the south east of Ardabil on Khalkhal Road out of which 18 kilometres (11 mi) is a hill section. The lake emerged during the Eocene geologic time scale. The Neor fault and another fault on the western part of the lake, which were active from the Eocene period, have contributed to the emergence of this lake. The basin receives an annual rainfall of 400 millimetres (16 in) with cold mountainous climate.
It is composed of smaller and larger basins, which get connected in rainy seasons forming a single lake. It has an average depth of 3 meters and is fed by springs in the lake bed. The maximum depth reaches 5 meters.
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-coloured fish. Among the fauna species found in the lake area are ruddy shelduck, and swallows which are the migrant species.
