Sampling: open water near reedbelt, depth about 3.5 m.

From Davies (1989) [Ref.18443]:
A very large freshwater lake with a maximum depth of 4.5 m. Its main inflow, the Khovd River, forms a vast delta at the west end of the lake, and much of the lake is occupied by macrophytes. The lake is connected to Har Nuur to the east by the Conoharayh Gol.
Climatic conditions: Extreme continental climate modified by altitude. The annual precipitation is in the region of 300 mm.
Principal vegetation: Up to 80% of the lake is covered with macrophytes; the dominant forms are floating-leafed aquatics such as Potamogeton and Nymphaea.
Land use: Fishing, harvesting of muskrats and livestock grazing.
Disturbances and threats: The Muskrat Ondatra zibethicus was introduced into the lake in 1967, and has become very abundant. Some 5,000 individuals were harvested annually in the 1970s (Dulma, 1979).
Economic and social values: The lake supports a locally important fishery.
Fauna: The fish fauna includes Oreoleuciscus pewzowi, 0. potanini, 0. humilis, Thyrnallus brevirostris and a bach Noemacheilus strauchi, all of which are endemic to western
Mongolia. The lake is considered to be one of the most important breeding and staging areas for migratory waterfowl, particularly ducks, geese and shorebirds, in Mongolia, but little information is available. The Demoiselle Crane Anthropoides virgo breeds in the area, and the
Common Crane Grus grus is known to occur in small numbers on migration.
