Geography
Krasnovishnevoye lies in the Baraba Lowland, West Siberian Plain. It is part of the Kyzyltuz lake group. The lake is shallow and has a roughly triangular shape. There is one islet in the southwestern sector. Located in an area of lakes, Krasnovishnevoye displays unusual characteristics compared to its immediate neighbors. One theory is that it is the site where a meteorite fell in the past. But so far no research has been carried out to establish whether there are meteorite fragments under the layer of salt and mud at the center of the lake.

Krasnovishnevoye has a pink color for the most part of the year. Its water is hypersaline. Regarding phytoplankton and presence of purple bacteria there are similarities between Krasnovishnevoye and some salt lakes of the Kulunda Plain, such as Malinovoye, but its harsher water conditions restrict its biodiversity to prokaryotes and unicellular algae.

Smaller lake Gorkoye straddles the border 0.7 km to the west and Bolshoye Topolnoye lies 80 km to the southeast. Lake Zharagash is in Kazakhstan, 41 km to the north, and Bolshoy Azhbulat 62 km to the SSE.
