Watershed Summary

The Eastern Sanilac Coastal Tributary Watersheds encompass approximately 114,560 acres of predominately agricultural land located on the eastern edge of the "thumb" area of Michigan. The Eastern Sanilac Coastal Tributary Watershed is approved under the CMI administrative rules and was funded under section 319. They are a series of small tributaries feeding into Lake Huron. Beaches at the outlets of the watersheds are used by residents and are important for tourism. Excessive sediment, bacteria, and nutrients were impairing the water quality of the tributaries and impacting the shore of Lake Huron. This project preserved its rural character, maintained tourism, enhanced fisheries, and improved the waters entering Lake Huron by reducing nonpoint source pollutants.
