Origin of title
A. Rogalyov believes that the name of the lake Svir is from Finnish languages and should be translated as “deep” ( Fin. Syveri - “deepening”, “deep place in water”, “depth”) [1] .
Basin structure
Hollow- type basin extending from the south-east to north-west. From the west, the high (up to 25 m) slopes of the Svirsky ridge closely adjoin, the eastern slopes are gently sloping - 3-5 meters high, overgrown with mixed forest . Floodplain in the east and north, up to 200 meters wide, under a rare bush , swamped, cut through by a network of reclamation canals . The shores are high (up to 0.7 m), in places merge with the slopes, the east - low, marshy. The waterline is 149.8 meters above sea level , the coastline forms several slightly pronounced bays. In the center and in the south there are sandy shoals (2 and 3.4 meters). The bottom to a depth of 4 meters is sandy and sandy - pebble , deeper sapropelic .
Water Mode
The lake is fed by the Bolshoy Perekop river in the southeast; the Smolka River, flowing from Lake Vishnevskoe , in the south; In addition, 9 streams flow into the lake. Precipitation and groundwater play a definite role in the inflow. The outflow occurs through the Sviritsa River (which flows to the north-west), as well as by evaporation from the water surface.
An open shallow hollow located along the line of prevailing winds contributes to intensive wind mixing of the water mass. Water salinity up to 260 mg / l, transparency up to 1 meter. Eutrophic . Strongly overgrown along the eastern shores, at the source Sviritsy and at the confluence of the Tar, the band of reeds and rogyza reaches 200 meters. Ice cover from the beginning of December to mid-April, the greatest thickness of ice is up to 1 meter.
