Using the Lake Champlain Basin SWAT watershed model results and BMP efficiency rates, Tetra Tech developed a spreadsheet-based tool that allows one to evaluate the amount of phosphorus reduction expected from different combinations of BMPs in Vermont Lake Champlain tributary watersheds. This report describes the design, function and data requirements for the scenario tool. (TetraTech, 2015c)
