It is a lake of Fresh water, of glacial origin which is fed by no large river nor torrent. It is usually not very deep, but its level can strongly fluctuate according to the seasons and the years.
Il however seems that formerly, the lake knew a cycle and that all the 30 to 35 years its water level went up so high that it ran out on a vast zone towards the west, filling of many small salted lakes. The level is sometimes assembled rather high so that the lake feeds the Irtysh river. When its level is low, one with the impression that there are several different lakes.

the botanists concerned there the exceptional habitats, which shelter more than 10 rare plants being reproduced on the Russian red list.

Ecoepidemiology

the virus H5N1 of the Avian flu was detected there mid-July 2005.

It is one of the sites which would deserve a fine follow-up because of the fact that it is a migratory crossroads for the birds.

the lake Chany and the constellation of wetlands and small lakes which surround it are an essential habitat for the rest the nourrissage or the migration of the birds of the palearctic one.

It is a nodal zone of first importance for the migratory birds in Siberia and all parlearctic north-be-European to the Indian sub-continent.

220 species of birds, is 80% of all the species likely to attend Siberia of the south and of the west are observed there.

250.000 Duck S and Foulque S can cotoyer on the lake in summer for then joining sectors of wintering located in Europe, in Africa, with the Close East or in the Indian sub-continent. It is what justifies that most of the site is classified “toilets and wetlands areas off international significance” with the title of the Convention of Ramsar.

For 25 years, 8 species of the Russian red list have been announced in reproduction on the lake or with the surroundings;

(Oxyura leucocephala);

(Himantopus himantopus) (15 to 20 individuals, but not every year)

(Recurvirostra avosetta) (10 to 50 couples); :

(Glareola nordmanni) (15 to 20 individuals);

(Larus ichthyaetus) (110 couples);

(Sterna caspia) (200 to 300 couples).

(Limnodromus semipalmatus) which is frequent along banks and of the islands of the lake Chany.
