Door County’s Potawatomi State Park has 2.5 miles of Lake Michigan shoreline and is a popular outdoor destination with more than 200,000 visitors each year. However, major storm events paired with the Park’s unique geologic features lead to significant flooding, campsite closures, and sediment-laden runoff from the campground and road into Lake Michigan. The construction of bioswales, ditch checks, and rip rap will reduce stormwater runoff and erosion, improve filtration, and ultimately improve both Lake Michigan water quality and the visitor experience.
