The principal aims of this study were to: (1) determine the density and distribution of nuisance cyanobacteria in the Oakwood Lakes system, (2) determine zooplankton biomass and nutrient concentrations and their distribution in the Oakwood Lakes system and (3) to estimate the amount of variability of dominant cyanobacteria biomass that can be explained by several zooplankton species biomass and nutrient concentrations. In addition, a biomanipulation experiment was designed to evaluate the effectiveness of zooplankton grazing on algal removal (cascading trophic interaction theory) in a prairie lake system.
