Abstract

According to the materials of multiyear studies, the author estimates the ecological status of forest lakes in the Omsk Priirtyshye with respect to the phytoplankton development indicators. The species composition, structure, and floristic similarity degree of the phytoplankton of polytypic forest lakes are described. The author also determines the trophic status and water quality of these lakes. It is found that excessive recreation has a negative impact on the ecological status of the lakes.
