Magnet Fishing in Minnesota: Lakes, Rivers and What DNR Allows

Minnesota has more lakes than you could fish in several lifetimes, and the upper Mississippi through Minneapolis is loaded with old bridge and industrial history. The Boundary Waters is off-limits — Wilderness designation means leave it completely alone. Everywhere else? DNR is pretty reasonable about it.

Typical Water Conditions

Minnesota has over 10,000 lakes plus the Mississippi River's headwaters — some of the best freshwater magnet fishing geography in the country. The Mississippi from Minneapolis south has old bridge infrastructure and industrial history. Lakes in the Boundary Waters and northwoods are clean and cold, though access can be limited by Wilderness designations.

Is it legal? Minnesota DNR doesn't explicitly prohibit magnet fishing, but Boundary Waters Canoe Area Wilderness has strict regulations that effectively prohibit any disturbing activity — leave it alone up there. Lakes and rivers outside federal Wilderness areas are generally accessible from public access points. Minnesota's State Archaeologist has jurisdiction over finds with cultural significance, especially Native American artifacts which carry federal protections under NAGPRA.

Best magnet fishing spots in Minnesota

1. Mississippi River at St. Anthony Falls

Minneapolis

This is the only natural waterfall on the entire Mississippi, and the area around the Stone Arch Bridge has been industrial since the 1800s — mills, factories, rail lines, all of it dumping stuff into the water for over a century. People have pulled out tools, hardware, old bolts, and chunks of machinery here. Access is solid with paved paths right along the riverbank and decent parking at the Mill Ruins Park lot.

Gear tip: The current near the falls can be surprisingly strong, so you want a magnet with serious pull and a rope you trust — check out Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm before you show up here with something flimsy.

2. Mississippi River at Stone Arch Bridge

Minneapolis

This is the most historically loaded stretch of water in the Twin Cities — the old mill district, flour industry infrastructure, and a century-plus of urban river traffic all concentrated right here. People have pulled chains, old tools, and industrial hardware from the water around the bridge piers. Access is solid, with paved trails and multiple points to drop a line off the banks or the lower observation areas.

Gear tip: The current here can be deceptive and the bottom is cluttered with heavy industrial junk, so you want a high-pull magnet and a rope with a solid knot — something like Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm will handle what this river throws at you.

3. Mississippi River — Stone Arch Bridge Area

Minneapolis

This stretch of the Mississippi runs through the old milling district, and there's over a century of industrial activity sitting on that riverbed. People have pulled up tools, hardware, old iron fittings — the kind of stuff that fell off barges and loading docks back when this was a working industrial corridor. Access is easy from the riverfront parkway, parking is close, and the water runs moderate depth off the bridge abutments.

Gear tip: The current here can be real, so you want a magnet with a strong pull rating and a rope you actually trust — check out Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm before you head out.

4. St. Croix River at Stillwater Lift Bridge

Stillwater

Stillwater's old lift bridge is one of the most recognizable landmarks on the St. Croix, and the riverbed underneath it has been collecting dropped and discarded metal since the lumber boom days. Coins, tools, old fasteners, and miscellaneous iron have all come up here. Just know the St. Croix is part of the National Scenic Riverway so keep the federal NPS rules in mind — you're not supposed to be removing archaeological artifacts.

Gear tip: You're throwing from a bridge or scrambling down a steep bank here, so a rope with solid knot security matters more than anything else — see what Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm recommends for bridge spots like this.

5. St. Croix River — Stillwater Bridge

Stillwater

Stillwater sits right on the St. Croix and has been a river town since the logging era, which means there's old hardware, chains, and iron debris that's been dropping into this river for over 150 years. The lift bridge area and the old downtown waterfront are the money spots. Just know that portions of the St. Croix fall under National Park Service rules, so check exactly where you're dropping before you start pulling.

Gear tip: The rocky shallows near the bridge can snag weaker magnets hard — bring something rated for solid retrieval and pair it with a good double-snap swivel setup; Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm has options worth looking at.

6. Mississippi River at Harriet Island Regional Park

St. Paul

Right across from downtown St. Paul, Harriet Island has been a public gathering spot for over 100 years and the riverbank has seen a lot of foot traffic, boat traffic, and general human activity that leaves metal behind. The park has easy walk-down access to the water and plenty of parking. Depth is manageable close to shore and the mud bottom holds things well — stuff doesn't drift far once it drops.

Gear tip: A double-sided magnet is overkill for the shallower edges here — a strong single-sided setup like what you'll find at Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm is plenty and easier to handle on a muddy bank.

7. Mississippi River — Harriet Island Regional Park

St. Paul

Right across from downtown St. Paul, this stretch of the Mississippi has seen paddlewheel traffic, barge landings, and a ton of recreational use over the decades. The park has easy riverbank access and decent parking, and the shallow edges near the docks have produced coins, tools, and old fasteners. Depth is manageable close to shore, which makes it a solid spot if you're not looking to work too hard.

Gear tip: For a spot with this much urban history in the water, you want a magnet that can handle soft silt and hard iron both — Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm is worth a look before your first drop here.

8. Mississippi River Lock and Dam No. 1

Minneapolis

Lock systems concentrate boat traffic and human activity in a small area for decades, which means the riverbed nearby is a slow-motion accumulation of dropped gear, tools, and hardware. The area around Ford Parkway and the east bank has decent foot access and you're not far from parking. The lock itself has been operating since 1917, so there's genuine history sitting down there.

Gear tip: Lock areas tend to have a mix of light junk and genuinely heavy iron, so bring something with real pull — Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm has options that won't quit on a stuck piece of old machinery.

9. Lake Minnetonka — Gray's Bay Dam

Minnetonka

Lake Minnetonka has been a recreational hotspot for over 100 years, and all that boat traffic, fishing activity, and shoreline history adds up to a lot of sunken metal. The Gray's Bay Dam outlet area concentrates debris that moves through the lake system and there's decent bank access with parking nearby. Shallow to moderate depth makes this a good spot for beginners getting comfortable with their setup.

Gear tip: Moderate depth and a mix of light recreational debris makes this a good place to run a single-sided magnet on shorter rope — Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm covers you well here without overcomplicating things.

10. Mille Lacs Lake — Garrison Public Access

Garrison

Mille Lacs is one of Minnesota's biggest lakes and the Garrison area has public boat landings and shore access that magnet fishers can actually use. Fishing culture here goes back generations, so lost tackle, anchors, and dropped gear from ice fishing season pile up near the access points over time. The bottom near the launch areas is relatively shallow and sandy, so you're not fighting a ton of resistance.

Gear tip: Sandy lake bottom near the launches means your magnet will drag pretty clean — a single-sided neodymium is plenty here; Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm can point you toward a good option.

11. Lake Minnehaha and Minnehaha Creek outlet

Minneapolis

Minnehaha Creek runs through one of the most visited parks in the Twin Cities, and the creek and its outlet area have collected decades of dropped metal from park visitors, old infrastructure, and general urban runoff. It's shallow enough for beginners and the banks are easy to access. Don't expect big iron — but coins, keys, and small tools show up pretty regularly.

Gear tip: Shallow creek fishing is where a lighter, compact magnet on a shorter rope actually makes sense — Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm can point you toward a setup that won't get constantly snagged on creek rock.

12. Minnesota River — Mankato Riverfront

Mankato

The Minnesota River runs through Mankato and the downtown riverfront area has old bridge infrastructure and flood history that tends to leave metal behind. The riverbank parks give you walkable access along the water, and the spots near former bridge crossings are where the interesting stuff concentrates. Depth is variable depending on season and rainfall, but the shallower bank sections are very workable.

Gear tip: Variable riverbed here — you might hit gravel, you might hit mud — so bring a rope long enough to change your angle if a snag happens; grab the right setup at Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm.

13. St. Louis River at Fond du Lac

Duluth

The St. Louis River feeds into Lake Superior near Duluth and the Fond du Lac area has old railroad and industrial history going back to the iron ore shipping era. The river bottom around old pilings and bridge remnants is worth working. Access trails run along the river and parking is available off Becks Road — it's not a manicured park setup but it's accessible.

Gear tip: Old pilings and submerged structural debris are exactly where ropes get snagged, so bring a rope rated for pulling hard — the options at Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm include some setups built for exactly this kind of rougher bottom.

14. Cannon River at Northfield Bridge Street Bridge

Northfield

Northfield's downtown bridges over the Cannon River are old, heavily trafficked, and surrounded by the kind of local history that puts interesting metal in the water. The river runs moderate depth here with gravel and silt bottom, and bank access is straightforward from the downtown area. It's a smaller, calmer waterway than the Mississippi, which makes retrieval a lot less complicated.

Gear tip: Calmer current and moderate depth make this a genuinely good beginner spot — Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm won't be overkill here, and you'll still pull enough to make the trip worth it.

15. Lake Minnetonka — Excelsior Commons

Excelsior

Excelsior Bay on Lake Minnetonka has been a recreational hub since the steamboat era, and the old docks and boat landings near the Commons have shed a lot of metal into that water over the years. The public access at Excelsior Commons puts you right on the shoreline with easy footing and no complicated permits. Expect lost fishing tackle, old dock hardware, and the occasional anchor chain fragment.

Gear tip: Dock areas mean you're likely hitting bolt-heavy debris, so a strong pull rating matters more than size here — Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm has solid choices for this kind of spot.

16. Minnesota River at Mankato Riverfront

Mankato

The Minnesota River through Mankato has a long history of ferry crossings, bridges, and industrial use, and the riverfront area downtown has been cleaned up and made accessible in recent years which actually makes magnet fishing easier to do without fighting through brush. The river runs with decent depth here and the bottom has old bridge hardware, anchors, and miscellaneous iron worth hunting. Parking is right there at Riverfront Drive.

Gear tip: River current here is real enough that you want a heavier magnet that doesn't skip across the bottom — Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm has solid picks for moving-water situations like this.

17. St. Croix River at Interstate State Park

Taylors Falls

The glacial potholes and dramatic rock formations at Interstate State Park make for a visually wild backdrop, but the river bottom near the old ferry crossing and boat landing areas is where magnet fishers focus. Old ferry hardware and anchor chains have historically been reported in this stretch. Again — NPS rules apply to the St. Croix here, so know what you're doing before you remove anything.

Gear tip: Rocky bottom and unpredictable snag points mean you want a rope with a strong, reliable knot system and a magnet that releases without a fight — Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm is a reasonable starting point for this terrain.

18. Red River — Moorhead Riverfront Park

Moorhead

The Red River forms the Minnesota-North Dakota border and the Moorhead side has riverside parks with real access to the water. It's a slow, muddy river which sounds boring until you realize slow muddy rivers tend to swallow things and keep them. Old bridge hardware, farm equipment fragments from upstream floods, and general iron debris have been pulled from this stretch.

Gear tip: Soft muddy bottom on the Red means you'll want to keep your rope angle steep to avoid burying your magnet — Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm is a good starting point for picking the right gear.

19. Mille Lacs Lake public boat landing at Garrison

Garrison

Mille Lacs is one of the biggest and most fished lakes in Minnesota, and the public boat landings — especially the main one near Garrison — have decades of dropped tackle, anchors, and equipment from fishing boats launching and loading. The near-shore area around the ramp is shallow and sandy, so recovery is easier than most lake spots. It's a high-traffic landing which means more stuff has gone in over the years.

Gear tip: Boat ramp areas are where you find real anchors and heavier hardware, so don't show up with an undersized magnet — Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm has the kind of pull rating that actually matters here.

20. St. Louis River — Jay Cooke State Park Access

Carlton

The St. Louis River tumbles through some dramatic terrain near Jay Cooke, and the old railroad and bridge history in this corridor is real — there were trestles and crossings here going back to the late 1800s. The rocky river sections hold iron debris from that era if you're willing to work the quieter pools rather than the fast rapids. Access is through the state park, so follow DNR public water rules.

Gear tip: Rocky river bottom means snag potential is high — use a rope with some stretch tolerance and a magnet you can retrieve at an angle; Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm can help you kit out right for this one.

21. Red River of the North at Moorhead Riverfront

Moorhead

The Red River forms the North Dakota border and the Moorhead stretch has old bridge sites, historic ferry crossings, and plenty of industrial use from the agricultural shipping era. The riverfront park gives you decent bank access and the river bottom here is soft mud — which means things sink in and stay put, sometimes for a very long time. You're also close to Fargo across the river so parking and logistics aren't a problem.

Gear tip: Mud bottoms can suction onto your magnet in a frustrating way, so a setup with a good retrieval knot and strong rope matters more than raw magnet size — see what Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm recommends.

22. Zumbro River at Rochester's Silver Lake Park

Rochester

Silver Lake is a warm-water reservoir fed by the Zumbro River, and the combination of long recreational use and old dam infrastructure makes it a decent magnet fishing target in southern Minnesota. The park has well-maintained access with paths along the water, and the shallow lake margins are easy to work without a lot of technical difficulty. Old fishing gear, anchors, and miscellaneous recreational hardware show up here regularly.

Gear tip: Shallow, calm water with a soft bottom — this is the kind of spot where you don't need to overthink the gear, but Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm will still out-pull anything underpowered if you hit heavier debris near the dam structure.

23. Coon Rapids Dam Regional Park — Mississippi River

Coon Rapids

The dam creates a distinct break in the river and the tailwater below it has accumulated decades of dropped and drifted metal. The regional park gives you legitimate shore access and there's parking right there, which is honestly more convenient than a lot of metro river spots. Fishermen have been working this area forever, so lost tackle and weights are a given, but the older iron stuff shows up too.

Gear tip: Tailwater zones below dams can have unpredictable current pull on your rope, so don't skimp on rope quality — Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm has what you need to do this spot properly.

24. Rum River at Anoka

Anoka

The Rum River flows into the Mississippi near Anoka and the confluence area plus the old downtown bridge site is a legitimately productive stretch. Anoka has one of the oldest Main Street bridges in the metro area and the riverbed under and near it has been picking up metal since the town was a frontier lumber stop. Access is easy from Rum River Central Regional Park and depth near the bridge is shallow enough to work comfortably.

Gear tip: A good all-around magnet fishing kit handles a spot like this perfectly — nothing exotic needed, just solid pull and a reliable rope, which is exactly what you'll find at Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm.

25. Minnesota River at Mankato's Sibley Park

Mankato

The Minnesota River has a long history of commercial and military use, and the Mankato stretch near Sibley Park sits close to where a lot of that activity was concentrated. The river bottom holds a mix of old industrial debris and recreational cast-offs from decades of park use. Bank access is easy from the park, and the river depth here is workable from shore without needing waders.

Gear tip: River current picks up seasonally here, especially in spring, so a higher-pull magnet on a long rope is smarter than going light — Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm handles moving water a lot better than entry-level kits when the Minnesota River is running strong.

26. Leech Lake — Federal Dam Public Access

Federal Dam

Leech Lake is massive and the Federal Dam access point puts you near the lake's outlet structure, which concentrates debris from decades of boat traffic and fishing activity. The area near the dam and the public landing has relatively easy shore access and the kind of shallow, sandy bottom that doesn't eat your magnet. Ice fishing culture on Leech Lake is huge, so winter equipment losses near the access are a real thing.

Gear tip: Big lake access points like this reward a little patience and methodical searching — bring a quality setup you can cast repeatedly without hand fatigue; Best Choice Magnets M8 Male Thread 200lb Round Magnet 44mm is a good place to start.

Magnet fishing in Minnesota — FAQ

Is magnet fishing legal in Minnesota?+
Generally yes, at public access points on lakes and rivers outside federal Wilderness areas. The big exception is the Boundary Waters Canoe Area Wilderness — regulations there effectively prohibit any disturbing activity, so don't even think about it. If you pull up anything that looks like it could be a Native American artifact, stop and contact Minnesota's State Archaeologist, because NAGPRA protections are real and serious.
Do I need a fishing license to magnet fish in Minnesota?+
No. Magnet fishing isn't regulated as fishing under Minnesota DNR rules, so you don't need a license. That said, you still need to be at a legal public access point — trespassing on private shoreline is a separate problem.
What pull force magnet should I use for Minnesota lakes?+
Somewhere between 500 and 1200 lbs covers most situations here. The soft silt bottoms on a lot of Minnesota lakes create suction that fights you as much as the weight of whatever you found, so going too light means you'll lose finds — and potentially your magnet.
Can I magnet fish in the Boundary Waters?+
No. The BWCAW has strict Wilderness-area regulations that prohibit disturbing activities, and magnet fishing would fall squarely in that category. There's plenty of great water in Minnesota outside the Boundary Waters — stick to the Mississippi corridor or the public lakes in the northwoods that aren't under federal Wilderness designation.
What's the best type of water to magnet fish in Minnesota?+
The Mississippi River from Minneapolis south is probably the most historically interesting — old bridge hardware, industrial runoff areas, and a long human history near the water. Lakes near old resorts or cabins that have been around since the mid-1900s are also worth checking, especially near old docks and boat launches.
What happens if I find something that looks like a historical artifact?+
Don't keep it and don't post it for sale. Minnesota's State Archaeologist has jurisdiction over culturally significant finds, and anything that looks like it could be a Native American artifact is protected under federal law. Set it aside, document where you found it, and report it.
How long of a rope do I need for Minnesota lake fishing?+
I'd go with at least 50 feet, and 100 feet if you're fishing off bridges or higher banks along the Mississippi. A lot of Minnesota lakes have gradual drop-offs near public access points, so you might be working in 15 feet of water most of the time — but it's better to have more rope than to come up short at a deeper spot.
Is magnet fishing good for beginners in Minnesota?+
Honestly, yes — the sheer number of accessible lakes makes it easy to find a spot close to home, and freshwater is more forgiving than tidal or ocean environments. The main thing beginners mess up here is underestimating how much the cold water affects grip and dexterity, so gloves matter more than people expect.

Here are some magnet fishing finds in Minnesota

Magnet fishing in Minnesota, as in many parts of the world, has led to a wide variety of finds, ranging from mundane items to unexpected treasures. The activity, which involves using a strong magnet to retrieve ferrous metal objects from bodies of water, often uncovers objects that have been submerged for years, offering a glimpse into the past or simply cleaning up modern-day debris. Here's a look at the types of finds people have reported during their magnet fishing adventures in Minnesota:


  • A community member recently reported finding a 400lbs gun safe door beneath the fishing dock on Como Lake.
  • Historical Artifacts: Minnesota's rich history means magnet fishers can sometimes pull up objects with historical significance. These finds could include old coins, antique tools, and even remnants from the state's industrial past or items related to the fur trade era. While not a daily occurrence, such discoveries can provide a fascinating link to history.
  • Weapons: It's not uncommon for magnet fishers to find weapons, ranging from guns and knives to old ammunition. These finds often prompt calls to local law enforcement, as they may be connected to criminal activities or historical collections.
  • Fishing Gear: Lakes and rivers are popular spots for fishing, leading to an abundance of submerged fishing equipment. Hooks, lures, and even larger items like fishing rods can get caught on magnets.
  • Bicycles and Scooters: As urban waterways are included in magnet fishing spots, bicycles, scooters, and parts thereof are frequently found. These are sometimes thrown into water bodies intentionally or lost accidentally.
  • Tools: Wrenches, hammers, and other tools that have accidentally fallen into the water are common finds. These items often show signs of wear and corrosion but are interesting finds nonetheless.
  • Jewelry: Rings, bracelets, and other pieces of jewelry are exciting finds, although less common. These items can sometimes be valuable and, in rare cases, returned to their owners.
  • Personal Items: Keys, watches, and even smartphones have been retrieved. These items offer a glimpse into the personal lives of individuals and the accidental losses that can happen around water.
  • Environmental Clean-Up: A significant portion of magnet fishing hauls consists of metal trash such as nails, screws, cans, and other debris. While these items might not be treasure, removing them from waterways contributes to environmental clean-up efforts.
  • Curiosities and Unidentifiable Objects: Occasionally, magnet fishers pull up objects that are so corroded or unique that they cannot easily be identified. These mysterious finds can be intriguing, sparking curiosity and research to determine their origins or uses.

Each magnet fishing expedition in Minnesota has the potential to uncover items that are mundane, historically significant, or somewhere in between. The variety of finds not only highlights the history and human activity associated with the state's waterways but also underscores the importance of environmental stewardship through the removal of debris from these natural resources.
