CHANGES IN THE RELATIVE TRANSPARENCY OF LAKE TELETSKOE WATER DURING THE SUMMER WARMING PERIOD 2014-2024

The results of expedition measurements of relative water transparency at 10 parts of the Lake Teletskoye water area during summer warming and stable temperature stratification in August from 2014 to 2024 are presented. It is shown that during the noted period there was a decrease the average relative transparency from 8,2 to 5,3 m. The reason for such a decrease in the relative transparency of the water of Lake Teletskoye may be an increase in the turbidity of the flowing rivers.
