Freshwater Improvement Scenario Builder
Explore how land use changes affect water quality and nitrogen, phosphorus loads.

This web tool lets you view current river and lake water quality results for key indicators, then model how different land mitigation or land use change scenarios could affect those results. It includes graphs and tables, and is set up to compare current conditions with predicted freshwater outcomes under different scenarios.
