Abstract

After carrying out bottom cleaning works on a part of Lake Manzherokskoye in 2017-2018, the quality of lake water did not significantly improve, and its transparency even significantly decreased. As our studies have shown, the reasons lay in the fact that after the bottom cleaning works, powerful bottom springs were opened, which began to intensively erode the remaining silt layer. To assess the geoecological state of the lake during the period of freeze-up and summer warming up, expeditionary hydrophysical studies of such parameters as horizontal and vertical velocities of water movement, integral and spectral transparency, temperature from surface to bottom were carried out. The results of these studies are presented in this article.
