Model My Watershed® lets users analyze real land use and soil data, model stormwater runoff and water-quality impacts, and compare how different conservation or development scenarios could modify runoff and water quality. Model My Watershed is part of the WikiWatershed Toolkit, an initiative to help citizens, conservation practitioners, municipal decision-makers, researchers, educators, and students advance knowledge and stewardship of fresh water.
