It is located in the Upper Mill Creek (UMC) watershed in Sharonville, where the East Fork Mill Creek flows into the Mill Creek mainstream. The preserve provides critical stream and wetland habitats for a broad array of aquatic organisms and is home to thousands of native plants. Guests can enjoy nature and wildlife observation from multiple viewing points, including an observation deck and a walking trail with informative signage around the wetlands.
