Optical properties and light climate in Lake Verevi,er lakes in same region since 1994. The upper water layer above the thermocline belongs to class “moderate” by optical classification of Estonian lakes but can turn “turbid” (concentration of chlorophyll . up to 73 mg m. and total suspended matter up to 13.2 g m.) during late summer blooms.

Long-term changes and seasonal development of phytoplankton in a strongly stratified, hypertrophic harge of urban wastewater, the trophic state of the lake has changed from moderately eutrophic to hypertrophic. We found that the trophic state in summer increased in the 1980s and remained at a hypertrophic level since then. . was recorded first in the 1950s and became the dominant species in the 1
