Metal detecting in Missouri state parks

Missouri State Parks (DNR) allows metal detecting only on designated sand beaches at 11 named parks: Cuivre River, Finger Lakes, Lake of the Ozarks, Lake Wappapello, Long Branch, Pomme de Terre, Stockton, Trail of Tears, Harry S Truman, Mark Twain, and Watkins Mill. You need a free annual metal-detecting registration and must carry it. Digging or probing tools are capped at 12″×3″ and sand scoops at 12″×6″ (no suction dredges or grappling hooks); you must carry a litter bag, and any historic or archaeological item — or any item worth $10 or more — must be reported to the facility manager. No object of historical or archaeological value may be removed.

Missouri’s antiquities law

Chapter 253 RSMo, especially §253.421, declares abandoned shipwrecks and embedded submerged historic materials to be state property, and prohibits salvage or excavation without a DNR permit (issued to professional archaeologists); violations are a class A misdemeanor.

Public land, lakes & local rules

Missouri is landlocked, so the designated “beaches” are inland lake swim areas at the 11 parks above, including Lake of the Ozarks, Stockton, Truman, Mark Twain, and Watkins Mill. City and county parks set their own rules, and some Missouri cities restrict or prohibit detecting — confirm locally. See our national guide.
