3M Flat Branch-Hinkson Creek Wetlands

A great place for bird-watching that includes a green roof shelter, picnic tables, and a 1.25 mile loop nature trail.

These wetlands were created to help filter stormwater runoff and provide habitat for wildlife. The former site was home to a sewer treatment plant along an important riparian forest corridor and was in need of restoration. Out of concern for the health and welfare of local streams, flora, and fauna, sixteen agency partners came together to restore this area and create the wetlands. The wetland cells treat stormwater runoff from approximately 140 acres of urban watershed and can store an estimated 10,000,000 gallons of runoff. The old sewer treatment pumphouse was repurposed into a viewing platform with a green roof. Visitors will enjoy viewing the wildlife that has been attracted to the improved habitat. In fact, the 3M Wetlands has become a “hot spot” in Missouri for bird sightings.
