River Day is designed to encourage appreciation and recreational use of the waterways of the Clinton River and Lake St. Clair and to celebrate the leadership of local citizens, organizations, and communities whose efforts are critical to protecting and enhancing the overall quality of the Clinton River watershed.

On June 7, 2025, individuals, businesses, community groups, and local governments across the watershed will join forces on River Day to enhance and celebrate the Clinton River and Lake St. Clair. Activities range from nature hikes, canoe trips, fishing derbies, and fly fishing lessons to storm drain stenciling, river clean-ups, habitat restoration, and native landscaping.
