The U.S. Corps of Engineers builds and runs many dams throughout the United States. The Corps buys up the land surrounding the area where the lake will be formed. It does lease some of this land back to States to make State Parks or other Recreation Areas on the lakes formed by the Corps Dam. The Corps has jurisdiction over all the waters backed up by the dam and the land surrounding the dam that they own. Carrying of firearms is only permitted for hunting purposes where hunting is allowed. The firearm carried must be legal for the type of hunting you are doing. The carry of Concealed Firearms is not legal on Corps Property.
