Overflow Creek is a major tributary of Bayou Bartholomew with a watershed encompassing approximately 98 square miles. The creek basin is very flood prone with heavy clay soils. Over time, several segments of the stream, its tributaries, and adjoining lands have been subject to alterations consisting of land clearing, channel excavation, weirs, earthen dams, road crossings, and levees.

These activities, in conjunction with a dense beaver population, have increased the frequency and duration of flooding the forested area resulting in a radically changed streamside habitat along the major waterways. What was once an oak/hickory forest has shifted to a more water tolerant habitat consisting of buttonbush, swamp privet, water locust, water elm, black willow, green ash, bald cypress, and water tupelo.

On slightly higher elevations that are still flood prone but not so severely impacted by beaver dams, the primary forest species are overcup oak, willow oak, delta post oak, cedar elm, green ash and persimmon. Nuttall oaks are noticeably few in number on these sites. The higher ridges adjacent to Oxbone Slough, Billotis Slough, and Beech Creek are dominated by cherrybark oak, shagbark hickory, nutmeg hickory, delta post oak, and cow oak. Loblolly pine and upland hardwoods occupy the higher elevations on the western boundary that abuts the West Gulf Coastal Plain.

About 2000 acres of marginal farmland have been reforested with a variety of hardwood species to closely represent the original forest species composition before the land was cleared. Another 2500 acres of cleared land in the lower elevations have been developed into a system of moist soil units that are managed on a rotational basis to accommodate the needs of the various groups of migratory birds consisting of waterfowl, wading birds, shorebirds, and rails.
