Site description Ganga Lake lies on the Dariganga plateau in Dariganga soum. The area has characteristics of both Gobi and steppe ecosystems. There are a number of small lakes at the site, including Ganga, Duut, Kholboo, Zegst, Tsagaan, Erdene, Sumt and Khoshmog Lakes, as well as sand dunes, for example Moltsog, Owoon and Kholboogiin Baruun. Zegst and Duut Lakes are fed by Dagsin spring waters and surrounded by reeds. Ganga Lake’s southern shore is covered by shrubs and woodland. The rest of the area supports dry steppe and desert steppe. Tourism is being developed at the site, and the use of off-road vehicles is having a negative impact on the vegetation and fragile soils. Ganga Lake and its surrounding wetlands were nominated as a Ramsar Site in 2004.
