Contamination
In addition to the fact that 10 species of fish live in this lake, pollutants enter the lake, they are dumped by local treatment facilities , which poorly clean sewage. They were also built in 1970 for a boarding house for the Bolsheviks (now it is closed, and in its place there is a center for social welfare Ezerkrasts). The content of nitrogenous substances is 15-20 mg / l (mainly nitrogen and phosphorus ). Moreover, the Malaya Yugla River flows into the lake, it and Lake Yugla may be in danger.
