The diatom populations in the plankton and periphyton at depths of three, nine and fifteen meters in the north and south basins of Lake George, New York have been characterized and measured over a three year period. Measurements of environmental factors, including solar radiation, temperature and algal nutrients concentrations, were also made at the same depths and locations. Relationships were established between environmental factors and numbers of diatoms through regression analysis. Diatom assemblages in recent surficial sediments and in consolidated sediment cores were characterized and present and past sedimentation rates determined. A predictive mathematical model was successfully tested with the data obtained making it possible to predict the future growth of certain diatoms in the lake from inputs of phosphorus and inorganic nitrogen.
