Wappapello Lake is a federally managed Corps reservoir

Wappapello Lake, on the St. Francis River just north and east of Butler County, is a U.S. Army Corps of Engineers reservoir managed by the St. Louis District. Built for flood control as well as recreation, it is federal land and water, so the rules for boating, camping, and anything along the shoreline come from the Corps rather than the county. For residents near Poplar Bluff it is a close outdoor destination, and for property questions near the lake the key point is that a federal authority manages the water and shoreline. The practical step is to check current Corps information for the lake before planning recreation or asking about shoreline use, since federal rules and conditions can differ from state parks or private lakes.
