Wisconsin Sea Grant is dedicated to enhancing the quality of coastal waters of lakes Michigan and Superior. We achieve this by developing local capacity to improve and protect water resources and educating Great Lakes basin residents, visitors and decision-makers about the causes and consequences of water-quality problems.
Wisconsin Sea Grant provides science-based information about the sources, transport and fate of contaminants in the Great Lakes, the cause-and-effect relationships between watershed activities and water quality, and the impacts of coastal development on nearshore habitats.
The Wisconsin Clean Marina Program provides guidance and education that enable marina and boatyard operators to protect the resources that sustain their livelihood: clean water, clean air, and healthy fish and wildlife communities. The program promotes voluntary adoption of measures to reduce pollution from marinas, boatyards and recreational boats. Facilities that adopt the recommended practices become certified as Wisconsin clean marinas. Learn more.

Lower Fox River total maximum daily load (TMDL)
Several streams and rivers in the Lower Fox River and Green Bay Basin are impaired due to excess amounts of phosphorus and sediments. A plan has been developed to improve water quality, know as a total maximum daily load (TMDL) for the Lower Fox River and Green Bay. Follow the links below for further information:
- Lower Fox River Basin information from the Wisconsin DNR
- Report: Total Maximum Daily Load and Watershed Management Plan for Total Phosphorus and Total Suspended Solids in the Lower Fox River Basin and Lower Green Bay
- TMDL information from the Wisconsin DNR
- Lower Green Bay and Fox River Area of Concern information from the Wisconsin DNR
