Description: The Brainerd levee and retention area were built in the 1970's to prevent flood waters from South Chickamauga Creek from damaging the neighborhoods in Brainerd. This stormwater control structure has created a freshwater marsh and seasonal mudflats. Habitats include a cattail marsh, seasonal mudflats, wet fields, wet woods, shallow ponds, fields with shrub and shrubby edges, and riparian woods.
Ornithological Importance: An assemblage of wetland species makes this a significant site for this area of Tennessee due to the lack of habitat.
