The invisible line on Lake St. Clair changes your fishing rules
Lake St. Clair is shallow, structure-rich and famous for smallmouth bass, muskellunge, walleye and yellow perch. But the first waypoint worth loading is not a fishing spot: it is the Michigan–Ontario boundary.
On one side you can use Michigan’s three-rod framework. Cross into Ontario and FMZ 19 uses two lines from a boat in open water. Bass seasons differ. Muskie limits differ. Pike and perch limits differ. Even a walleye under 15 inches changes from legal-size in Ontario to undersized in Michigan.
Lake St. Clair fishing status at a glance
Smallmouth bass
Michigan possession season is open. Ontario FMZ 19 bass season is also open.
Muskellunge
Michigan possession remains open through Dec. 31. Ontario season ends Dec. 15.
Walleye
Six/day on either side under current Lake St. Clair rules, but Michigan requires 15 inches.
Yellow perch
Michigan daily limit 25. Ontario Sport daily limit 50.
Northern pike
Michigan and Ontario use substantially different harvest limits.
Lake sturgeon
Michigan possession is currently open through Sept. 30. Ontario sturgeon is closed all year.

Lake St. Clair species rules anglers should not mix together
| Species | Michigan | Ontario / FMZ 19 | Practical trap |
|---|---|---|---|
| Walleye | 6/day • open all year • 15″ minimum • 3 rods | Sport 6 / Conservation 2 • open all year • no Lake St. Clair minimum • 2 lines from boat | A 14-inch walleye that meets Ontario’s Lake St. Clair size rule is still undersized in Michigan. |
| Largemouth + smallmouth bass | 14″ minimum • 5 combined • possession Jun 20-Dec 31 • CIR generally year-round | Sport 6 / Conservation 2 combined • season Jun 27-Nov 30 | Ontario does not give Lake St. Clair the same year-round bass CIR framework used by Michigan. |
| Muskellunge | Possession Jun 6-Dec 31 • 42″ minimum • 1 per licence year • register harvest within 24 hours | Jun 6-Dec 15 • Sport 1 greater than 112 cm • Conservation 0 | Ontario’s minimum is roughly 44.1 inches and its season ends earlier. |
| Northern pike | 24″ minimum • 2/day • open all year | Sport 6 / Conservation 2 • open all year | Michigan’s bag is much smaller and adds a minimum length. |
| Yellow perch | No size minimum • 25/day • open all year | Sport 50/day, possession 100 • Conservation 25/day, possession 50 | A Canadian angler crossing west cannot carry Ontario’s higher perch assumption into Michigan water. |
| Lake sturgeon | Fishing Jul 16-Mar 15 • possession Jul 16-Sep 30 • 42″-50″ slot • 1/year • 24-hour registration | CLOSED ALL YEAR | This is one of the sharpest rule changes on the entire lake. |
Michigan and Ontario bass rules diverge before June 27
Catch-and-immediate-release generally allowed year-round. Possession starts June 20, 2026.
FMZ 19 bass season runs June 27-November 30, 2026. Do not import Michigan’s early CIR rule into Ontario.
Six Lake St. Clair checks take less than a minute
Michigan or Ontario?
Correct privilege for that side?
Open for targeting/retention?
Minimum, slot or maximum?
Daily and possession totals?
Muskie/sturgeon harvest?
Lake St. Clair sturgeon is a slot fishery—not simply “open”
On the Michigan side, the 2026 Lake St. Clair / St. Clair River lake-sturgeon fishing season runs July 16 through March 15.
But the possession season ends September 30. A legally retained fish must fall within Michigan’s 42-50 inch retainable range.
Harvest checklist
- Maximum 1 harvested lake sturgeon per angler per licence year.
- Harvest must be registered within 24 hours.
- Michigan reporting number: 888-636-7778.
- Online reporting is also available through Michigan DNR.
- Ontario FMZ 19 lake sturgeon is closed all year.
Pick the launch that shortens the run to your fishing water
Clinton River Cut-Off
A major rebuilt DNR access site near the western side of Lake St. Clair.
36110 Jefferson Ave., Harrison Township, MI
Good choice forAnchor Bay, Mile Roads, central flats and anglers wanting high-capacity public trailer access.
Lake St. Clair Metropark
Eight ramps near the North Marina along Black Creek.
31300 Metro Parkway, Harrison Township, MI 48045
Pass systemCurrent Metroparks page lists $10 daily vehicle and $10 daily boat passes; a trailered boat requires the applicable boat pass in addition to vehicle entry.
Belle River Marina
Practical east-side launch for anglers fishing Ontario water.
Day-pass price includes tax. Season pass $198 + HST; senior season pass $136 + HST.
North Marina dockage is not the same thing as the boat-launch ramps
Lake St. Clair Metropark’s North Marina has been closed since 2019 because of infrastructure and utility damage associated with high water. A major reconstruction project is currently underway.
Metroparks says the rebuilt marina is expected to reopen with 78 transient slips by Memorial Day 2027. At the same time, the park’s current boating page still lists eight launch ramps near the North Marina along Black Creek.
Secondary public launch / shore-access options worth checking
Harley Ensign Memorial
Michigan DNR lists this public access for the Clinton River / Lake St. Clair system.
DNR shore-fishing material also identifies shore and wading access. Check the current ramp/dock status before a long drive.
Selfridge Boating Access
Michigan continues to list Selfridge as a DNR boating access site serving Lake St. Clair.
Older DNR shore-fishing material identifies seawall fishing here; verify current access conditions on arrival.
Why carry a backup ramp?
Shallow-lake weeds, maintenance, construction, severe weather or crowding can make your first launch less useful than expected.
Save two launch options on the same side of the lake before leaving home.
A fishing licence does not automatically pay for DNR ramp parking
Recreation Passport when bought with licence-plate registration renewal.
Michigan Recreation Passport does not replace Metroparks’ own pass.
Lake St. Clair Metropark is one of the easiest structured shore options
Huron Point
1.5 milesMetroparks lists approximately 1.5 miles of shoreline fishing for bass, walleye, pike and perch.
Black Creek accessible pier
- Low railings
- Benches with backs / arm rests
- Elevated tackle-box surface
- Cement pathways
- Accessible van parking
- Accessible portable toilet nearby
Seasonal shore restriction
Metroparks says shoreline fishing is not permitted along the beach or at the marinas from April through October.
Lake St. Clair sits directly across the Michigan–Ontario border
Google Maps is useful for orientation only. Use a navigation chart or GPS layer capable of showing the actual international boundary when fishing near it.
Five Lake St. Clair zones that call for different approaches
Shallow northern water with vegetation, sand/grass transitions and broad flats.
Think: smallmouth, pike, perch and muskie.
Classic Michigan-side bass water where subtle bottom changes and quality vegetation can concentrate smallmouth.
Think: tube, dropshot, Ned rig, jerkbait.
Large expanses of similar depth make bait, isolated hard bottom and weed quality more useful than simply fishing a depth number.
Think: roaming bass, walleye and muskie.
Current and channel structure create a different fishery from the open basin.
Think: walleye, muskie and current-related bass.
Vegetation-oriented Ontario water that can suit pike, bass, perch and multi-species fishing.
Remember: FMZ 19 rules.
Lake St. Clair smallmouth do not all roam the entire lake together
Michigan DNR’s Lake St. Clair smallmouth telemetry work tracked hundreds of tagged bass and found meaningful grouping between the Anchor Bay and Mile Roads areas. Many fish stayed within their basic areas rather than constantly mixing lake-wide, although some individual bass made large movements.
Can behave like a distinct local group rather than automatically shifting to the Mile Roads.
DNR telemetry found separation between important bass-use areas.
Individual fish still made substantial movements, including some cross-lake movement.
A practical August Lake St. Clair starting plan
Search transitions
Start on productive vegetation edges, sand-to-grass changes, scattered hard bottom or current-influenced structure.
First toolsDropshot • tube • Ned rig • jerkbait
Find bait first
Large weed flats, channel edges and current seams become more useful when forage is present.
RulePrepare net, cutters and release tools before the strike.
Cover water
Channels, flats and current influence can suit trolling when fish are spread out.
OptionsCrankbaits • crawler harnesses • jigging when concentrated
Stay with the school
Perch can shift quickly across flats. A waypoint is useful only while the school remains there.
OptionsSmall jigs • legally sourced minnows / bait
Target → habitat → first presentation
| Target | Start looking | First presentation | Move when… |
|---|---|---|---|
| Smallmouth | Weed edge, sand/grass, rock, current | Tube / dropshot / Ned / jerkbait | No bait, poor vegetation and no bites across the transition |
| Muskie | Big flats, weeds, channels, bait | Heavy casting tackle or trolling | Forage or usable vegetation disappears |
| Walleye | Channel edge / open flat / current | Crankbait / crawler harness / jig | Electronics show no fish or bait across a meaningful pass |
| Yellow perch | Schooling fish on flat or transition | Small jig / legal minnow | Catch rate falls because the school moved |
| Northern pike | Weedline / bay / ambush edge | Spoon / spinnerbait / jerkbait | Vegetation becomes dead, muddy or bait-free |
Buy bait for the side you are fishing instead of moving it casually across the region
Personally collected bait stays with its original water
Michigan’s 2026 rule says baitfish or fish personally collected for bait / cut bait may only be used for fishing in the original waters of collection and on a hook.
- Purchase bait from a properly licensed source.
- Do not dump unused bait into the lake.
- Imported VHS-susceptible bait has certification requirements.
- Drain livewell and bilge water before road transport.
FMZ 19 uses the Great Lakes bait framework
The Great Lakes are outside Ontario’s four normal Bait Management Zones. Movement depends on whether bait is dead/preserved or live/unpreserved.
- Baitfish limit: 120 including caught + purchased.
- Crayfish limit: 36.
- Crayfish must be used in the waterbody where caught.
- Crayfish may not be transported overland.
- Dead + preserved bait has broader movement allowances.
Natural bait or artificials?
Small jigs and legally sourced minnows are straightforward starting options.
Crawler harnesses, crankbaits and jigs let you switch between covering water and fishing concentrated marks.
Tubes, dropshots, Ned rigs and jerkbaits reduce the need to manage live-bait transport.
Large artificials are the normal practical approach and avoid most cross-border live-bait complications.
Clean, drain and inspect before the trailer touches the road
Clean
Remove aquatic plants, plant fragments, mud and visible organisms from boat, trailer and equipment.
Drain
Remove drain plugs and drain bilges, ballast tanks and livewells before transporting the watercraft over land.
Dry / decontaminate
Dry gear before another waterbody when practical, or use an appropriate cleaning/decontamination method.
Michigan’s three rods do not become three rods in Ontario
Michigan DNR’s current St. Clair River / Lake St. Clair walleye regulation table lists three rods per angler.
FMZ 19 allows two lines when angling from a boat in open water.
Licence the water you actually plan to fish
2026 Michigan prices
Michigan generally requires a fishing licence at age 17+. Current 2026 licences remain valid through March 31, 2027.
Common 2026 Ontario choices
Ontario Outdoors Card: $8.57. The one-day Sport licence does not require an Outdoors Card. Fee products are subject to 13% HST.
Save the actual Licence Summary PDF—not only a screenshot
Screenshot / photo
Ontario says a photograph or screenshot of the Licence Summary is not valid as the digital document.
Official PDF
Keep the PDF supplied by the Fish and Wildlife Licensing Service on the mobile device, or carry the appropriate paper/card proof.
Fishing jurisdiction and customs reporting are two separate systems
U.S. / foreign boater enters Canadian water only
CBSA’s current private-boater guidance provides a reporting exception for a foreign boater who enters Canadian waters but:
- does not land in Canada,
- does not anchor or moor,
- does not contact another conveyance,
- does not embark/disembark people or goods.
If those conditions change
If you land, anchor, moor or make contact with another vessel, CBSA says you must report immediately.
Canadian Telephone Reporting Centre: 1-888-226-7277.
Fish caught near the Lange-Revere Canals need a separate meal check
Michigan’s 2026 Southeast Eat Safe Fish Guide gives a special Lake St. Clair table for fish caught within two miles of the Lange-Revere Canals, between Lakefront Park and Veteran’s Memorial Park and extending into open water.
| Fish | Size | 2026 MDHHS advice |
|---|---|---|
| Bluegill | Any | 6 MI servings/year • 2x notation |
| Carp | Any | Limited |
| Largemouth bass | Under 20″ | 1/month • 2x notation |
| Largemouth bass | Over 20″ | 1/month |
| Muskellunge | Any | DO NOT EAT |
| Smallmouth bass | Under 20″ | 1/month • 2x notation |
| Smallmouth bass | Over 20″ | 1/month |
| Sunfish | Any | 6 MI servings/year • 2x notation |
| Walleye | Any | 6 MI servings/year • 2x notation |
| Yellow perch | Any | 2/month • 2x notation |
| All other species | Any | Limited |
ALL FISH: DO NOT EAT
MDHHS’s 2026 guide lists all species from the Lange-Revere Canals themselves as Do Not Eat because of PCB contamination.
MDHHS says the listed MI servings can be doubled when the chemical of concern is suitable for reduction through the “Choose, Clean, Cook” approach and the fish is not listed as Limited. The doubling does not apply when mercury or PFOS is the chemical preventing it.
Set up the release tools before a 40-pound fish is beside the boat
- Use heavy enough tackle to avoid an unnecessarily long fight.
- Keep a muskie-size landing net assembled and reachable.
- Carry long-nose pliers.
- Carry strong hook cutters for difficult hook positions.
- Keep the fish supported in water while hooks are removed where practical.
- Minimize air exposure for any photograph or measurement.
- On Michigan water, register any legally harvested muskie within 24 hours.
- Recheck which country you are in before assuming the fish is legally retainable.
Watch a Lake St. Clair Metropark bass approach

Wind matters more here than the “11-foot average” makes it sound
Open wind across a shallow basin can create a rougher ride than the contour map suggests.
Wind can quickly muddy a shallow productive flat.
Judge the forecast for the trip back—not only the conditions at launch.
Launch closer to the fishing side instead of making a long exposed crossing simply because a ramp is familiar.
Ice-fishing permission does not certify safe ice
Lake St. Clair Metropark permits ice fishing in designated canals, the North Boat Basin and open lake areas when conditions permit, and Lake St. Clair is a popular winter perch fishery.
Michigan also allows yellow-perch harvest on Lake St. Clair using a hand-propelled spear, bow and arrow or crossbow from December 1 through March 15 under the current regulation.
Lake St. Clair pre-trip checklist
- Load the international boundary on your GPS/chartplotter.
- Choose Michigan, Ontario or both before buying licences.
- Save today’s species rule for bass, muskie, walleye, pike, perch or sturgeon.
- Measure Michigan walleye with a real ruler—not visual guesswork.
- Count rods/lines according to your current side of the lake.
- Confirm ramp status and entry fee the morning of the trip.
- Save a backup ramp on the same side of the lake.
- Buy bait legally and avoid unnecessary cross-jurisdiction transport.
- Clean and drain the boat before road transport.
- Check marine wind and storm information before a long open-water run.
- Check CBSA/CBP rules if the trip crosses the international boundary.
- Check MDHHS consumption guidance before eating Michigan-side fish, especially near Lange-Revere.

Questions worth answering before you launch
What is the Michigan walleye limit on Lake St. Clair in 2026?
Michigan currently allows six walleye per day on Lake St. Clair. The season is open all year, the minimum size is 15 inches and the current table lists three rods per angler.
What is the Ontario walleye limit on Lake St. Clair?
Ontario FMZ 19 allows Sport-6 and Conservation-2 walleye and sauger combined. The season is open all year and the Lake St. Clair cross-border regulation table lists no Ontario minimum size.
Can I catch-and-release bass early on the Ontario side?
Do not apply Michigan’s year-round catch-and-immediate-release bass rule to Ontario. FMZ 19 lists the largemouth and smallmouth bass season from the fourth Saturday in June through November 30. In 2026 that begins June 27.
When does Michigan Lake St. Clair bass possession open in 2026?
Michigan’s Lake St. Clair, St. Clair River and Detroit River possession season opens on the third Saturday in June. In 2026 that date is June 20 and the season continues through December 31.
What is the Lake St. Clair muskie size limit?
Michigan generally uses a 42-inch minimum on Lake St. Clair, with one muskellunge harvest per angler per licence year and mandatory reporting within 24 hours. Ontario FMZ 19 allows a Sport angler one muskie that must be greater than 112 centimetres; the Conservation limit is zero.
Can I keep lake sturgeon from Lake St. Clair right now?
On the Michigan side, the 2026 possession season runs July 16 through September 30 and the retainable size window is 42 to 50 inches. Harvest is limited to one per licence year and must be registered within 24 hours. Ontario FMZ 19 lake sturgeon is closed all year.
Can I fish with three rods anywhere on Lake St. Clair?
No. Michigan’s current Lake St. Clair walleye table lists three rods per angler. Ontario FMZ 19 allows two lines while angling from a boat in open water.
Can I use two rods from shore on the Ontario side?
Do not assume so. Ontario’s general rule is one line unless another rule states otherwise. FMZ 19’s special two-line allowance applies while angling from a boat in open water.
What are the best public boat launches on Lake St. Clair?
High-utility public options include Michigan DNR’s Clinton River Cut-Off Boating Access Site, Lake St. Clair Metropark and Ontario’s Belle River Marina. Harley Ensign and Selfridge are additional Michigan DNR access sites worth checking for current conditions.
Is Lake St. Clair Metropark North Marina open in 2026?
The North Marina remains under reconstruction and Metroparks currently expects it to reopen by Memorial Day 2027. The park’s main boating page separately continues to list eight boat-launch ramps near the North Marina along Black Creek, so check the status of the exact facility you need.
Can I move live bait to Lake St. Clair from another Michigan lake?
Michigan’s 2026 rules state that personally collected fish used as bait or cut bait may only be used for fishing in the original waters where they were collected and must be used on a hook. Purchased bait should come from a properly licensed source.
Can I eat fish from the Lange-Revere Canals?
Michigan’s 2026 Eat Safe Fish Guide lists all species caught from the Lange-Revere Canals themselves as Do Not Eat because of PCB contamination. A separate special advisory applies to Lake St. Clair within two miles of the canals.
Do I have to report to Canada just for crossing into Canadian water?
CBSA currently provides a reporting exception for foreign boaters who enter Canadian waters without landing, anchoring, mooring, contacting another conveyance or exchanging people or goods. If those conditions change, reporting requirements can apply. This exception does not replace Ontario fishing-licence or FMZ 19 requirements.
Fish the habitat—but manage the boundary
Lake St. Clair rewards anglers who pay attention to subtle things: grass quality, water clarity, bait, current, wind and small depth changes. But before any of those matter legally, know which side of the Michigan–Ontario line you are fishing.
