State & public land
No verdict yetNo cited source sets a detector rule for Missouri state land. RSMo 253.420 and 253.421 cover historic shipwrecks on lands beneath navigable waters (see the lakes_rivers dig and keep rules).
Lakes & rivers
Digging
Research permits onlySalvaging or excavating a submerged or embedded abandoned shipwreck that meets National Register criteria needs a DNR permit, and the applicant must be or hire a professional archaeologist.
- 'embedded': firmly affixed in lands, so that excavation tools are needed to reach the wreck or its cargo
- a detailed plan must be approved; written permission from any affected landowner (253.421.3)
- permit fee $100; decision within 30 days
- violation: class A misdemeanor; each day is a separate offense; collected material becomes state property
What the rule says
“no person, corporation, partnership, proprietorship or organization shall initiate salvage operations, excavation or similar ground disturbing activities of any submerged or embedded abandoned shipwreck in this state which meets the national register of historic places criteria without obtaining a permit from the department of natural resources”
Keeping finds
ProhibitedHistoric shipwreck materials and other abandoned objects of historical or archaeological value on lands beneath Missouri's navigable waters belong to the state.
- 'historic shipwreck': over fifty years old, including structure, cargo, personal items, and monetary or treasure trove
- 'lands beneath navigable waters': up to the ordinary high water mark, including filled or reclaimed former riverbed
What the rule says
“all historic shipwreck materials and such objects having intrinsic or historical and archaeological value which have been abandoned on lands beneath navigable waters shall belong to the state”
Public land & lakes
Varies by siteLake shores inside Missouri state parks follow the designated-beach registration rules; detecting on shores outside those parks was not confirmed.
- free registration with Missouri State Parks first
- specific sand beaches at 11 state parks only
- shores outside state parks: no rule confirmed; ask the managing agency
What the rule says
“metal detecting is allowed in certain areas in 11 state parks; however, registration is required. The activity is allowed only on specific sand beaches at these state parks”
Local & federal
Varies by siteCity and county rules vary; Kansas City, for example, allows detecting in approved park areas with a $25 yearly registration and bars it at historic sites, athletic fields and several named parks.
- Kansas City: yearly registration ($25); approved areas only, sunrise to sunset
- Kansas City: not on athletic fields, historic sites, memorial grounds, golf courses, battlefields, dog parks or plant beds, and not at Loose, Indian Mound or Frank Vaydik parks or Union Cemetery
- Kansas City: hand tools only, holes no more than 3 inches deep and wide; report historical finds to park staff
- other cities and counties: ask the parks department
What the rule says
“metal detecting is allowed in approved areas throughout our park system. Registration is required and valid for one year from date of registration.”
Federal land
No verdict yetA general federal-land detector rule was not confirmed in this review; ask the specific land manager.
Even where detecting is allowed, archaeological and historic sites are protected, and you must fill every hole and follow posted rules. Always confirm the current rule with the land manager.
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
RSMo §253.421 vests specified submerged antiquities on lands beneath navigable waters in the state. Section 253.420 requires a DNR permit for salvage, excavation or similar ground disturbance of submerged or embedded abandoned shipwrecks in Missouri that meet National Register criteria; an applicant must be a professional archaeologist or hire one. Violating §253.420 is 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.
