From the Decatur Parks & Recreation Department Website:

The St. Marys Nature Preserve debuted in 2017, adding about 3/4 mile to the existing Rivergreenway Trail system. The highlight of the new section of the greenway is a pier that overlooks the pond. The pier is great for taking a break or fishing, and is ADA accessible. A handful of benches are situated throughout the new trail, as well as informational signage to learn about the animals and plants that are native to our area. This project was made possible in part by a grant from the Department of Natural Resources Land and Water Conservation Fund.
