Attempts at lake restoration by artificial aeration with the use of wind energy were made on the heavily eutrophic Lake Starodworskie. The lake is small - only 7 ha surface area but deep - 23 m. Artificial aeration was performed by destratification method. Compressed air, produced with the help of a wind turbine was subsequently delivered to the deepest site in the lake. As show the study results from 1985-87, the effects of the applied method were limited. Breaks in aeration caused by lack of winds or too low windpower prevented full destruction of thermal and chemical stratification. However, in the hypolimnion some temperature increase was observed, and oxygenation improvement - minor in summer and considerable in the other seasons. Moreover, the content of organic compounds and nutrients (especially phosphorus) decreased.
