What the Black River offers anglers

The Black River near Croswell is a slow-moving, meandering stream that holds walleye, northern pike, and channel catfish in a landscape of swamps, marshland, and agricultural fields. The river is narrow—often 30 to 50 feet wide—with depths ranging from 2 to 8 feet in most sections, though deeper holes and bends can reach 12 feet. The bottom is soft mud and silt, and the water is stained to tea-colored, which means walleye here are less light-sensitive than they are in clearer lakes and will feed throughout the day, especially around structure.

This is not a destination fishery like Saginaw Bay or the Au Sable, but it is a solid local resource for anglers in Sanilac County who want to fish a river system without traveling far. The character of the water—slow current, heavy vegetation, and low-pressure conditions—makes it different from the faster, clearer rivers in the northern Lower Peninsula. Walleye fishing peaks in spring and fall, while pike are present year-round and can be caught on live bait or large artificials.

Key Takeaways

  • The Black River near Croswell holds walleye, northern pike, and channel catfish in slow, stained water with soft bottom and heavy vegetation.
  • Spring and fall are the most productive seasons for walleye; pike fishing is consistent throughout the year.
  • Access is limited; the main public launch is at the Croswell Township boat ramp on M-90, and bank fishing is possible in scattered locations along county roads.
  • Live bait—shiners, crawfish, and nightcrawlers—outperforms artificials in this stained-water system.
  • A Michigan fishing license is required; check current regulations for walleye and pike size and bag limits before you fish.

Where to launch and how to access the river

The Croswell Township boat ramp on M-90 (near the village of Croswell) is the primary public access point. It is a simple concrete ramp with parking for a handful of vehicles and a gravel lot. The ramp can be muddy after rain, and the river is shallow here, so launching a large boat is not practical; most anglers use 14- to 17-foot aluminum boats or canoes. The ramp is free and open year-round, though winter access depends on road conditions.

Bank fishing is possible along several county roads that cross or run parallel to the river, particularly north and south of Croswell. Look for pull-offs near bridges and culverts. The land adjacent to the river is a mix of private property and public easements, so always check before you cross a fence. The river is also accessible by canoe from the launch point; the current is gentle enough that paddling upstream is feasible, and the slow pace makes it easy to fish as you go.

Walleye fishing in spring and fall

Walleye in the Black River respond best to live bait fished on or near the bottom. In spring (April through May), focus on deeper bends and holes where walleye move after spawning. A 1/8-ounce jig tipped with a live shiner or a slip-sinker rig with a live crawler works well. Cast toward the outside of bends where the current (though slow) has scoured deeper water, and work the bait slowly along the bottom.

Fall fishing (September through October) is often more consistent. Walleye move into shallower areas as water cools, and you can find them in 3 to 6 feet of water around vegetation and woody debris. Nightcrawlers and shiners are both effective. Fish early morning and late evening when light is low, but do not skip midday—the stained water means walleye feed throughout the day if the bait is in the right spot.

Summer is slower because walleye move into the deepest holes and are less active in warm water. Winter fishing is possible through the ice, but the river is narrow and shallow in most places, making it less reliable than nearby lakes.

Northern pike and live bait tactics

Pike in the Black River are aggressive and will chase large shiners, crawfish, and even small bluegill. Live bait is the most consistent method. Use a 6- to 8-inch shiner on a quick-strike rig (a small treble hook above a larger single hook) or a simple slip-sinker setup with a live bait. Cast near vegetation, fallen trees, and the outside of bends, and let the bait work naturally. Pike will often follow and strike hard.

Artificial lures—large spinnerbaits, crankbaits, and soft plastics in the 4- to 6-inch range—can work, especially in spring and fall when pike are more active. Retrieve slowly and pause frequently to let the lure sink into deeper pockets. The stained water means pike rely more on vibration and lateral-line detection than sight, so lures with rattle chambers or strong action are worth trying.

Seasonal patterns and water conditions

The Black River is influenced by groundwater and seasonal runoff, so water levels and clarity vary. Spring snowmelt and heavy rain can raise the water level and increase stain, which actually improves walleye fishing by reducing light penetration. Summer low water can concentrate fish in deeper holes but also makes navigation difficult in a shallow boat.

Water temperature is slower to change in this system than in lakes because the slow current and heavy vegetation moderate swings. Fall cooling is gradual, which means the walleye bite can remain good well into November if weather stays mild. Winter ice-out is typically mid-April, and the river is usually fishable by late April.

Regulations and licensing

A valid Michigan fishing license is required. You can purchase a license online through the Michigan Department of Natural Resources website, at sporting goods stores, or at the Croswell Township office. Licenses are available as daily, three-day, or annual options.

Walleye and pike regulations change annually and vary by water body. Check the current Michigan fishing guide for the Black River specifically—size limits, bag limits, and season dates are listed by county and water body. As of recent years, walleye have a 15-inch minimum size and a daily bag limit, while pike have no minimum size in many Michigan rivers, but always verify before you fish. Catfish have no size limit in most cases.

What to bring and how to fish safely

Bring a small tackle box with jigs (1/8 to 1/4 ounce), hooks (size 2 to 1/0), slip sinkers, and live bait containers. A net is useful for landing pike. Wear a personal flotation device if you are in a boat, and be aware that the river can be narrow and winding—visibility around bends is limited. The banks are soft and muddy in many places, so wear boots with good grip.

Mosquitoes and biting flies are heavy in summer, especially near vegetation. Bring insect repellent. The water is stained, so if you fall in, you will not see the bottom; a PFD is not optional. Cell service can be spotty in the marshland surrounding the river, so let someone know where you are fishing and when you expect to return.

Frequently Asked Questions

Can I fish the Black River in winter?

Yes, ice fishing is possible once the river freezes solid, usually by mid-December. The river is shallow and narrow, so the ice is generally safe, but always check thickness before you venture out. Walleye and pike can be caught through the ice using live bait or small jigging spoons. Access is limited to bank fishing or walking on the ice near the Croswell ramp.

What size boat do I need?

A 14- to 17-foot aluminum boat is ideal. The river is narrow and shallow, so large boats are difficult to navigate and launch. A canoe or small jon boat works well and gives you more flexibility to explore shallow areas and fish from the bow.

Is the Black River better for walleye or pike?

Both are present and catchable. Walleye fishing is more consistent in spring and fall, while pike are active year-round. If you want numbers, pike are easier to catch; if you want a specific target, focus on walleye in cooler months.

Where can I buy live bait near Croswell?

Bait shops in Croswell and nearby Sandusky carry shiners, crawfish, and nightcrawlers. Call ahead to confirm availability, especially in winter. Some anglers catch their own shiners using a small net or trap in the river itself.

What is the best time of day to fish?

Early morning and late evening are productive, but the stained water means walleye and pike feed throughout the day. Midday fishing is often overlooked and can be just as good as dawn and dusk, especially if you are fishing deep holes or heavy cover.
