What to know
Located in southeast Arkansas in Ashley County, Overflow National Wildlife Refuge was established in 1980 to protect one of the remaining bottomland hardwood forests considered vital for maintaining mallard, wood duck, and other waterfowl populations in the Mississippi Flyway. This 13,000 + acre wetland complex consists of seasonally flooded bottomland hardwood forests, impoundments, and croplands. During the winter, a 4,000- acre greentree reservoir is created when the bottomland hardwood forests are allowed to flood. This seasonally flooded area provides a haven for mallards, wood ducks, and other waterfowl species.
