This 4,809-acre area is composed of the 2,355-acre Atlanta tract and the 2,454-acre Long Branch tract. The Conservation Department purchased the Atlanta tract in 1960. The management of the Long Branch tract was assumed in 1978, under license from the U.S. Army Corps of Engineers.
The East Fork of the Little Chariton River runs three miles through the NW portion of the Long Branch tract, which includes the upper reaches of Long Branch Lake.
The area is gently rolling, except for the bottomlands. The forest is predominately oak/hickory in the uplands and mixed hardwoods in the lowlands and contains a variety of woodland edge and grassland wildlife. The area also contains three managed marshes, totaling approximately 90 acres, and several natural oxbow lakes.
The Conservation Department manages the resources of this area to provide public recreation and protect soil and water quality. Management practices include farming, timber harvest, and prescribed fire. Some ponds and Long Branch Lake contain a variety of sport fish.
