SWAT Model Configuration, Calibration and Validation for Lake Champlain Basin

The Soil and Water Assessment Tool (SWAT) model was used to develop phosphorus loading estimates for sources in the Lake Champlain Basin. This document describes the model setup and parameterization, and presents calibration results. The model accounts for loads from Vermont, New York and Quebec, but includes more detail on the Vermont portion of the watershed given that EPA is responsible for developing Vermont phosphorus load and wasteload allocations. The detailed calibration results are included in appendices C - K, organized by watershed or groups of watersheds. (TetraTech, 2015b)
