Dynamics of Environmental Status of the Lake Turgoyak

Abstract
The article discusses the environmental status of the unique oligotrophic Lake Turgoyak (Southern Ural). The age characteristics of the lake hollow and the maximum depths of the lake are specified. The dynamics of the ongoing changes at the lake ecosystem since the first scientific description of the lake in 1903–1912 until today is considered.. Anthropogenic impact on the lake is revealed. A gradual increase in water mineralization and a tendency to increase the concentration of total phosphorus were discovered. In the last 3–4 years, a steady decrease in the transparency of the lake waters has been observed; the lake has began to “bloom”. The transition of the lake to the oligotrophic-mesotrophic state is noted. The main reasons of the negative changes in lake ecosystem are the unsatisfactory condition of the sewage system, and the increasing recreational load on the coast and water area. The measures to preserve the lake were outlined, in particular, it was proposed to increase the conservation status of the lake.
