Model My Watershed is currently only available for the continental United States because it is built with U.S. Geological Service watershed data.
WikiWatershed is an initiative of Stroud™ Water Research Center. The Stroud Center seeks to advance knowledge and stewardship of freshwater systems through global research, education, and watershed restoration.
Model My Watershed will be undergoing scheduled maintenance on Monday, January 17 from 11 a.m. to 3 p.m. EST. The model will be unavailable during that time.
Upgrade announcement coming soon!
