The Vollenweider, Dillon, and Larsen/Mercier models for predicting ambient lake phosphorus concentrations and classifying lakes by trophic state are compared in this report. The Dillon and Larsen/Mercier models gave comparable results in ranking 39 lakes relative to known ambient phosphorus concentrations. The Vollenweider model, which does not include a phosphorus retention capacity component, was unable to achieve the high rank correlations found with the other models. Trophic state predictions from the phosphorus loading models are compared with National Eutrophication Survey lake report designations.
