Abstract: Eutrophication of lakes and reservoirs as a result of anthropogenic input of nutrients, especially phosphorus (P) and nitrogen (N) cause serious water quality concern in the upper Great Plains. Excessive nutrient load results in excessive development of phytoplankton and rooted aquatic plants. High phytoplankton growth leads to DO consumption during nights. The purpose of this research is specifically, to evaluate effect of the aeration system on change of phytoplankton shift of species. Specific objectives are: 1. To identify phytoplankton species during the seasons and the cause(s) algae patterns; 2. To conduct on site measurements and laboratory analyses of lake water samples to determine effect on aeration system in relation to phytoplankton environmental factors; 3. To determine physical and chemical factors favoring cyanobacteria dominance and blooms in eutrophic lake, and to define impact of aeration system on cyanobacteria growth through change in nutrient availability
