Teel River, and has no outflow. The lake is surrounded by grassland steppe and low rolling hills. There are marshes with reed beds where the Teel River enters the lake. The main land uses at the site are hay collection and livestock grazing. The railway from Ereentsav to Choibalsan passes along the western side of the lake.
