Metal detecting is prohibited within Onalaska city limits due to ordinances banning turf excavation on public property. You’ll need to detect on private land with owner permission or obtain a DNR permit for state-managed properties, which requires Form 9400-239 and restricts activity to May 1-October 15 during designated hours (7-10am or 6-9pm). You can’t remove archaeological materials over 50 years old, and all recovered items must be presented to property offices immediately. The article below outlines complete permit procedures, reporting requirements, and compliance standards.

Understanding Onalaska’s Metal Detecting Prohibitions
Where can you legally use a metal detector in Onalaska, Wisconsin? You’re facing significant restrictions. Onalaska enforces ordinances that ban digging into turf and prohibit metal detecting entirely within city limits. This prohibition stems from public perception considerations regarding archaeological site protection and resource preservation. You’ll need stakeholder engagement strategies if you’re seeking changes to these regulations.
State-owned lands, parks, and campgrounds remain off-limits. DNR lands require permits exclusively for recovering specific lost personal items, with searches restricted to May 1 through October 15 during designated hours. You can’t touch archaeological materials over 50 years old or items within recorded historic sites.
Your best option? Private property with explicit landowner permission. There, you’re exempt from ARPA restrictions and DNR prohibitions, giving you freedom to detect without regulatory constraints. However, DNR cannot prohibit metal detector use in shallow water up to 6 feet deep on department or stewardship land that isn’t historically significant. Online forums and communities can provide valuable first-hand experiences about navigating local metal detecting restrictions in Wisconsin.
Wisconsin State Law Requirements for Metal Detector Users
Before you operate a metal detector on Wisconsin’s DNR lands, you must obtain a special permit limited exclusively to recovering specific lost personal items. Your permit application requires describing the exact items you’ve lost, and searches are restricted to specific areas between May 1 and October 15. You’ll present all recovered items to the property office for verification—they’ll retain anything not belonging to you.
You can’t remove archaeological materials 50 years old or older, and detecting within burial areas is prohibited. While local law enforcement reporting requirements don’t typically apply to standard detecting activities, public awareness campaigns emphasize compliance. Archaeological Resources Protection Act violations carry serious penalties. Submit your permit form to the property manager, understanding that opportunities statewide remain extremely limited for protecting historical resources. If you discover any archaeological sites during your search, you must obtain review and approval from a DNR archaeologist before proceeding. Developed sites like campgrounds are generally open to metal detecting unless archaeological or historical resources are present.
DNR Permit Application Process and Timeline
When you’re metal detecting on Wisconsin DNR-managed properties near Onalaska, you must submit Form 9400-239 with complete documentation before beginning any activities. The state imposes seasonal restrictions limiting metal detecting to the period between May 1 and October 15, with specific time windows you’ll need to observe.
Your permit application requires DNR approval, and the agency maintains strict limits on the number of permits issued per property to minimize environmental impact. You can submit applications and other forms to the DNR online for some permits. Note that sandy beach areas do not require a permit for metal detector use, making them an accessible option for detecting activities.
Required Form and Documentation
Metal detector users must complete Form 9400-239, titled Metal Detector User Permit, to legally operate detection equipment on Wisconsin DNR-managed properties. You’ll need to provide your name, address, and signature on this standardized form.
The application requires detailed descriptions of specific lost items you’re seeking—permits authorize personal property recovery only, not general treasure hunting.
Your submission must specify search area parameters within DNR lands and your requested timeframe between May 1 and October 15. You’re restricted to daily windows of 7:00-10:00 a.m. or 6:00-9:00 p.m.
Submit your completed form directly to the property manager for superintendent approval. Dane County Parks requires a one-year permit for metal detecting activities on their parklands. You must carry this signed permit during all detecting activities, as it’s subject to verification under Wisconsin’s compliance enforcement protocols.
Seasonal Restrictions and Timing
Since Wisconsin DNR regulations impose strict temporal boundaries on metal detecting activities, you must operate exclusively within the May 1 to October 15 window established under s. NR 45.04(3)(i), Wis. Adm. Code. Your permit’s validity dates fall within this seasonal timeline consideration, explicitly listed on the approved form.
You’re restricted to two daily windows: 7:00 a.m. to 10:00 a.m. or 6:00 p.m. to 9:00 p.m. These hours enable visitor interference prevention by confining your search activities to periods of minimal park use. The property superintendent determines your exact operational dates when signing your permit.
You can’t extend detection beyond October 15, and winter months remain completely off-limits. Submit your application early to secure preferred dates within the allowable season, ensuring you’ve got adequate time for your detecting pursuits. The DNR conducts independent review of all permit submittals to verify compliance with applicable regulations before approval. The permit fee must be paid after provisional approval but before the department issues your final permit.
Approval and Permit Limits
You’ll need to fill out Form 9400-239 and submit it to the DNR Property Office in Madison before conducting any metal detecting activities on state-managed lands. Your application must identify the specific lost item you’re recovering, the owner’s information, and your preferred search area.
Onalaska permit requirements mandate that you’re searching for particular personal items—not prospecting generally. You can only detect during designated time windows: 7:00 a.m. to 10:00 a.m. or 6:00 p.m. to 9:00 p.m., between May 1 and October 15. The DNR superintendent must authorize your permit before you begin.
When evaluating Onalaska detection locations on DNR property, you’ll need this permit in your possession at all times. For city-specific regulations, contact Onalaska’s clerk office directly.
Permitted Hours and Locations on State Properties
Wisconsin’s Department of Natural Resources restricts metal detecting on state properties to specific seasonal windows and daily timeframes. You’ll only operate between May 1 and October 15, during morning slots (7:00 a.m. to 10:00 a.m.) or evening slots (6:00 p.m. to 9:00 p.m.). Your permit designates which time period applies.
Your search techniques must remain within specified property boundaries marked on your permit. You can’t access recorded archaeological sites without DNR archaeologist approval, and burial areas are generally off-limits. The designated search area applies across all DNR-managed lands, waters, state parks, forests, and riverways.
Enforcement officers may remove you from property for 48 hours if violations occur. You’re required to carry your signed permit form at all times, as property managers can terminate authorization verbally without notice. Current regulations now prohibit detecting on areas that were previously open to hobbyists without restriction.
Age Restrictions for Archaeological Materials and Artifacts
You must understand that federal and state laws impose different age thresholds for archaeological materials you encounter while metal detecting.
The Archaeological Resources Protection Act (ARPA) prohibits removal of artifacts over 100 years old from federal lands, while Wisconsin DNR interpretations apply a 50-year threshold to certain items on state properties.
Any discovery of potentially historic materials requires you to report findings to the property manager or DNR, as removal without proper assessment violates preservation statutes.
100-Year Federal ARPA Threshold
You’ll face restrictions once objects cross this temporal boundary. Items under 100 years typically don’t trigger ARPA enforcement unless they possess archaeological significance through context or association. This threshold exists to preserve finite historical assets while allowing freedom for recent material culture.
Wisconsin’s DNR aligned state policies with these federal mandates in 2009, requiring you to report century-old discoveries to state historians rather than pocketing them.
50-Year DNR State Limit
While federal ARPA establishes a 100-year benchmark, the Wisconsin DNR enforces a more restrictive 50-year threshold for archaeological materials on state-managed lands and waters. You’ll find this limit applies to all man-made objects reaching that age threshold, effectively protecting items from 1975 and earlier as of 2025.
The DNR’s revised policy protection, implemented in 2009, mandates these materials remain in undisturbed archaeological context regardless of their apparent significance. You can’t remove these items even with a metal detecting permit—those authorizations only cover lost personal property. DNR archaeologists strictly interpret this regulation, making no distinction between recorded and unrecorded sites. You’re responsible for leaving any artifact meeting the 50-year criterion exactly where you discover it on DNR properties.
Reporting Requirements for Finds
When recovering items through metal detecting on Wisconsin DNR property, you’re legally obligated to present all finds to the property office for comparison against your permit’s item description pursuant to s. NR 45.04(3)(i), Wis. Adm. Code. The property office retains anything not matching your permit specifications.
You can’t remove archaeological materials 50 years or older from their locations, regardless of inspector eligibility determinations. ARPA federally prohibits taking man-made objects over 100 years old from public ground, with severe penalties for violations.
While detector certification requirements don’t exist formally, you must surrender archaeologically significant items to state historians. Contact the DNR historic preservation officer at 608-445-8395 before disturbing potential artifacts. This reporting protocol protects your legal standing while preserving Wisconsin’s historical resources.
Private Property vs. Public Land Regulations
Metal detecting regulations in Onalaska operate under two distinct legal frameworks depending on land ownership.
Private Property Access
You’ll find considerably more freedom on private land. ARPA doesn’t apply, and there’re no state-level prohibitions restricting your activities. You can remove artifacts over 100 years old without restriction, provided you’ve secured landowner consent. This consent requirement represents your only legal obligation—written permission remains mandatory before you begin detecting.
Public Land Restrictions
Public lands impose extensive limitations on your detecting rights. Wisconsin generally prohibits metal detecting on state-owned property. You’re restricted to specific sandy beaches and shallow water areas. Onalaska’s local ordinances ban metal detecting entirely and prohibit digging into turf. Even with DNR permits, you’re limited to recovering specific lost personal items during designated timeframes. Archaeological protections further restrict removal of items over 50 years old.
Chequamegon-Nicolet National Forest Detecting Guidelines
Federal lands introduce additional regulatory layers beyond Onalaska’s municipal boundaries. Within the administrative boundaries of national forest areas like Chequamegon-Nicolet, you’ll navigate specific protocols that govern recreational metal detecting zones.
Core Requirements for Forest Service Lands:
- Permitted Zones – You’re authorized in developed campgrounds, swimming beaches, and recreation sites where heritage resources aren’t present.
- Prohibited Territory – Archaeological sites, historical sites, and Quartz Hill in Oconto County remain strictly off-limits due to unauthorized digging impacts.
- Permit Threshold – Casual recreational use doesn’t require permits, but you’ll need a Notice of Intent if your activities could disturb resources or land.
- Operational Standards – You must leave areas in original condition and consult the local Forest Service office for zone-specific guidelines before detecting.
Reporting Requirements and Item Retention Policies
You must present all recovered items to the DNR property office immediately upon recovery for comparison with your permit description. The property office retains any items that don’t belong to you, including all archaeological materials 50 years or older and non-personal finds.
Your permit authorizes recovery of only the specific lost personal items described in your application, and all other discoveries become state property under Wisconsin Administrative Code s. NR 45.04(3)(i).
Mandatory Find Reporting Process
When you recover any item while metal detecting on Wisconsin DNR lands in the Onalaska area, you’re required to present it immediately to the property office for comparison against your permit’s lost item description. The reporting timeline is strict—”immediately upon recovery” means no delays.
While Onalaska lacks a specific city-wide local reporting process for finds, state mandates apply to all DNR properties.
Your reporting obligations include:
- Immediate presentation of all recovered items to the designated property office
- Surrender of non-matching items that don’t belong to the permittee
- Archaeological materials (50+ years old) must remain untouched at recovery location
- Historical significance items delivered directly to state archaeologists
Failure to comply risks permit revocation and potential legal penalties under state regulations.
DNR Property Office Retention
Under Wisconsin DNR regulations, property offices exercise broad retention authority over items recovered during permitted metal detecting activities on state lands near Onalaska. You’ll find that any materials not matching your permit application’s specific recovery description become state property automatically. The property superintendent compares your finds against your Form 9400-239 descriptions, retaining anything outside those parameters under NR 45.04(3)(w)1.
Item recordation procedures require you to present all recovered materials to the property office for comparison and documentation. However, retention duration guidelines aren’t specified in available regulations—the DNR maintains custody indefinitely once items are retained.
Materials exceeding fifty years old, archaeological artifacts, and anything from historic sites face automatic retention regardless of your permit descriptions, giving you no recovery rights for historical items.
Archaeological Items Surrender Rules
Metal detecting on state lands triggers mandatory surrender protocols whenever you encounter archaeological materials during permitted activities. Wisconsin’s artifact removal policies require you to leave any archaeological or historic items undisturbed and immediately notify the DNR’s Departmental Archaeologist. Cultural resource management regulations prohibit you from keeping discoveries that fall outside your permit’s scope for personal property recovery.
Required actions when encountering archaeological materials:
- Cease excavation immediately upon discovering items predating your permitted timeframe or description
- Leave artifacts in place without further disturbance to preserve contextual information
- Report findings to the DNR property office for comparison against your permit specifications
- Surrender all retained items to the property office, which holds authority to determine ownership and disposition
These protocols protect Wisconsin’s archaeological heritage while allowing you legitimate personal property recovery rights.
Restoration Obligations and Compliance Standards
Although metal detecting permits grant access to designated DNR properties, you’re legally bound to restore all excavated areas to their original condition immediately upon concluding your activities. This requirement enforces original landscape preservation across state-owned lands under DNR control. Property managers hold termination authority—exercisable verbally—if you fail compliance checks.
Your responsibilities extend beyond simple backfilling. Soil disturbance minimization demands careful excavation techniques that preserve root systems and natural contours. You’ll reimburse DNR for damages resulting from your actions or omissions, with forfeitures reaching $2,000 for natural resource damage. Intentional archaeological feature damage triggers harsher penalties: $10,000 fines or nine-month imprisonment terms. Courts may additionally order restoration of damaged archaeological features, with equipment confiscation possible for submerged resource violations.
Contact Information for DNR Historic Preservation Office
You’ll need direct access to specialized DNR personnel when maneuvering metal detecting regulations and cultural resource concerns in Wisconsin. Mark Dudzik serves as DNR’s primary archaeologist for heritage resource programs, coordinating with local cultural preservation societies on compliance matters.

Frequently Asked Questions
Can I Metal Detect on Frozen Lake Ice in Winter Months?
No, you can’t metal detect on frozen lake ice during winter months. Coincidentally, permits only authorize May 1-October 15 activities. You’re restricted regardless of checking for trespassing signs or accessing lake property restrictions—Wisconsin prohibits detectors on waters year-round.
Are Battery-Powered Pinpointers Subject to the Same Permit Requirements as Detectors?
Battery-powered pinpointers aren’t explicitly regulated under DNR permits, which target “metal detectors.” However, local park regulations in Onalaska prohibit metal detecting broadly, potentially including pinpointers. You’ll need clarification from authorities before using any detection device on public property.
What Penalties Apply for Violating Onalaska’s Metal Detecting Ordinances?
No specific metal detecting penalties exist in Onalaska’s code. General violations incur $25-$500 fines first offense, $50-$1,000 repeat offenses. Undocumented permit enforcement and metal detector confiscation procedures aren’t established. You’ll face standard municipal forfeiture provisions if ordinances apply.
Do Children Need Separate Permits or Can They Detect Under Parents?
Children need separate permits on DNR lands since permits specify one individual, not family groups. However, Onalaska’s county parks lack permit mandates, allowing supervised activities freely. Age restrictions aren’t explicitly defined, giving you flexibility for family detecting.
How Long Does DNR Typically Take to Approve or Deny Permits?
The DNR doesn’t publish standard approval timelines for the permit application process. You’ll need to contact them directly at 608-445-8395 to determine processing times, especially considering seasonal time constraints that might affect your detecting plans.
