Lake Champlain Basin Pollution Reduction Calculator

Lake Champlain potential project Mapping tool

In 2024, the LCLGRPB updated the Lake Champlain Nonpoint Source Pollution Subwatershed Assessment and Management Plan, identifying 99 projects and programs. This update includes 37 new projects, all within the New York portion of the Lake Champlain Watershed.

To assist implementation partners, an online mapper was developed as a comprehensive database of identified projects. It includes project narratives, funding sources, involved parties, and project locations with latitude and longitude coordinates.

Lake Champlain Phosphorus Reduction Mapper

The Lake Champlain Nonpoint Source Pollution Subwatershed Assessment and Management Plan was completed in 2018 and has since been used by the LCLGRPB, members of CWICNY, and individual municipalities to apply and receive funding for effective water quality projects throughout the Lake Champlain Basin. To further assist in advancing targeted phosphorus reduction projects, the LCLGRPB has created an online resource for local and regional resource managers.

With support from the Lake Champlain Basin Program, pollutant load reductions were calculated for over 150 non-agricultural, nonpoint source projects identified in the 2018 Plan, utilizing the NYS DEC Pollutant Load Reduction Calculator. The Phosphorus Reduction Mapper presents pollutant reductions in pounds per acre per year for three key waterbody contaminants: phosphorus, nitrogen, and sediment. Each project’s reductions were estimated using the most effective potential management practices.

How to use the map

• Click the image below to access the mapper
• Sort projects by County, Subwatershed, Area of Concern (e.g., erosion, stormwater), Best Management Practice, or project ID
• Select a red circle, which represents a project’s location and ID
• View project details, including its area of concern, BMP, practice area, and pollutant reductions
