The surface area is 7.65 km², the catchment area is 110 km², the greatest depth is 3.1 m, the average depth is 1.9 m, and the coastline is 12.5 km. Lake Sho occupies a vast depression, formerly the bottom of a large glacial lake. Now it is a residual body of water, which is also expressed in the flat topography of the bed. The slopes and shores of the lake are swampy and peaty , only in the west, where the flat sandy plain is close, they rise to 0.5 m, the approaches to the lake are convenient, the slopes are 3-4 m high.

Due to its shallow depths and a flat open basin , in summer the lake is equally well warmed from bottom to surface and saturated with oxygen. In winter, the difference in the oxygen content, the amount of which decreases at the bottom to 30-40%, is more noticeable. High transparency of 2 m serves as an indicator of the relative purity of water, despite the high content of organic substances (oxidizability of more than 10 mg / l).

Most of the bed is lined with finely detrital sapropel , littoral - with sand, silted sand (0.5-1 m). The sediment layer has a volume of 31.4 million m³, of which sapropels - 27.5 million m³. A powerful layer of sediments rich in organic substances makes it possible to use them as fertilizers. There are 55 species of algae in phytoplankton . The dominant position in weight in the total biomass and in the number of cells in a liter is blue-green . Total phytoplankton biomass : 2.42 g / m³. There are 26 species in zooplankton characteristic of shallow eutrophic water bodies. Biomass 2.36 g / m³. Flowing lake. Streams and channels flow from the lakes Dolgoe and , the river Shosha flows.

Lake Shaw is rich in fish: crucian carp , tench , pike , perch , roach . Repeatedly stocked with carp , crucian carp.

The human influence on Lake Shaw is manifested only in fishing and fish farming . At the same time, Shaw Lake has significant fodder resources and its fish productivity can be increased.
