August A. Busch Jr. Memorial Wetlands at Four Rivers Conservation Area spans nearly 14,000 acres across Vernon and Bates Counties with multiple boat ramps (some seasonally closed), parking areas, and disabled accessible facilities.

The area features 20 pools and marshes managed for waterfowl and wildlife, with specific hunting and fishing restrictions by zone and season—notably, lead shot is prohibited and firearms deer hunting is restricted in certain units.

Primitive camping is available, and the headquarters provides access information for planning your visit to this expansive wetland recreation area.
