      The Generalized Watershed Loading Functions model was applied to the Sodus East Creek watershed to predict streamflow and sediment and nutrient loads. Actual discharge and sediment and nutrient loads were measured by conventional hydrologic and chemical techniques. During a two year period, the model explained 44 % of the total monthly variability in discharge. Total discharge was underestimated by an average of 74%. Potential factors contributing to the underestimation of discharge were investigated and assessed accordingly. Factors investigated were precipitation measurement, discharge measurement, aquifer locations, watershed characteristics and model performance. Analysis of these factors suggested that model inaccuracy was not the result of a single factor but rather multiple factors, both hydraulic and model related.
