What You'll Find at Black River Near Croswell

The Black River near Croswell is a modest warmwater stream in the Thumb region of Michigan, roughly 90 minutes northeast of Detroit. It holds smallmouth bass and walleye as its primary species, with occasional channel catfish and panfish. The river moves slowly through farmland and light woods, making it accessible to anglers of varying skill levels. Water clarity is usually moderate to good, and the stream is narrow enough that you can fish most sections from shore or a small boat.

This is not a destination river — it won't draw you across the state. But if you live in the Thumb or are passing through, it offers a straightforward half-day or full-day outing without crowds. The fishing is most consistent in spring and fall, when water temperatures favor both smallmouth and walleye movement.

Key Takeaways

  • Smallmouth bass and walleye are the main species; spring and fall produce the most reliable fishing.
  • Access points exist at bridge crossings and a few informal pull-offs, but parking is limited and you should scout ahead.
  • A Michigan fishing license is required; no special endorsement is needed for this stream.
  • The river is shallow and slow-moving, so wading is often possible, but water levels can rise quickly after rain.
  • Croswell is the nearest town with gas, food, and basic supplies; plan accordingly if you're traveling from a distance.

Seasons and Water Conditions

Spring (April through May) is the strongest season for both smallmouth and walleye. As water temperatures climb from the 40s to the low 60s, both species move into shallower areas to feed and spawn. Walleye fishing peaks in the first two weeks of May, when they're in pre-spawn and spawn mode. Smallmouth follow a few weeks later as water reaches the mid-60s.

Summer (June through August) slows considerably. Water warms into the 70s, and both species retreat to deeper holes and current breaks. Early morning and evening fishing can still produce, but midday is often slow. By late summer, water levels sometimes drop, exposing shallow bars and making navigation trickier.

Fall (September through October) brings a second strong window. As water cools back into the 60s and 50s, smallmouth and walleye become active again. This period often produces larger fish than spring, as both species have had all summer to feed. October is particularly good for walleye.

Winter (November through March) is not practical for most anglers. Water temperatures drop into the 30s and 40s, and ice can form on slower sections. A few dedicated anglers fish for walleye in December and January, but access becomes difficult and fish are sluggish.

Access Points and How to Get There

The Black River has no developed public boat launch or designated fishing access area. Instead, you'll rely on bridge crossings and informal pull-offs along county roads. The most reliable access is at bridge crossings on M-90 (near Croswell itself) and on local roads south and east of town. Parking is typically shoulder parking along the road — space is limited, and you should not block farm gates or private driveways.

From Croswell, head south on M-90 or east on local roads (County Road 5600 and similar) to find bridge crossings. Scout these locations before you plan a trip; water access and parking conditions change seasonally and after heavy rain. Some crossings have better sight lines and safer parking than others. Never park on private property without permission.

Wading is the most common approach. The river is typically 20 to 40 feet wide and 2 to 5 feet deep in most sections, making it wadeable for much of the year. Wear felt-soled waders or boots with good grip, as the bottom is often silty and slippery. A small canoe or kayak works well if you want to cover more water, but be aware of fallen trees and low-hanging branches — scouting by foot first is wise.

Fish Species and What to Target

Smallmouth bass are the most abundant species. They hold around current breaks, fallen trees, and deeper holes. In spring, fish shallow areas near the banks where they're spawning. By summer, they move to deeper pools and undercut banks. Smallmouth here average 12 to 16 inches, with occasional fish to 18 inches. They respond well to small crankbaits, soft plastics (4- to 6-inch worms and crawfish imitations), and live crayfish.

Walleye are present but less abundant than smallmouth. They prefer deeper, slower pools and are most active at dawn, dusk, and night. Spring and fall are your best windows. Walleye here typically run 14 to 20 inches. Fish live minnows (shiners or shad) under a slip bobber in deeper holes, or cast small jigs tipped with minnow. Night fishing with live bait often outproduces daytime efforts.

Channel catfish show up in summer and early fall, particularly in deeper pools. They're not the main draw, but if you're fishing live bait for walleye, you may hook one. Panfish (bluegill, pumpkinseed) are scattered throughout and provide a backup option if bass and walleye are slow.

Regulations and Licensing

You must have a valid Michigan fishing license. A resident annual license costs a set fee (check the Michigan Department of Natural Resources website for current pricing). Non-residents can purchase a 24-hour or 7-day license at lower cost than an annual pass.

Smallmouth bass have a 12-inch minimum size limit and a daily bag limit of five fish. Walleye have a 15-inch minimum and a daily bag limit of five fish. Channel catfish have no size limit and a daily bag limit of 25. Panfish (bluegill, pumpkinseed) have no size limit and a daily bag limit of 50. These regulations can change, so verify with the Michigan DNR before you fish.

No special endorsements or stamps are required for this stream. Fishing hours are from 30 minutes before sunrise to 30 minutes after sunset, except for walleye, which may be fished at night (check current rules for any night-fishing restrictions on this specific water).

Gear and Tackle Recommendations

For smallmouth, bring a 6- to 6.5-foot medium-power spinning rod with 8- to 10-pound braided or monofilament line. Crankbaits in the 2- to 3-inch range, soft plastic worms (4 to 6 inches), and small jigs (1/8 to 1/4 ounce) all work. A few live crayfish in a small bucket will often outfish artificials.

For walleye, a similar rod works, but consider dropping to 6- to 8-pound line if you're casting small jigs. Live minnows (shiners, shad, or small bluegill) are your most reliable bait. Bring a slip-bobber rig for fishing deeper holes, and have a few small jigs (1/16 to 1/8 ounce) tipped with minnow for casting. Night fishing is productive, so a headlamp is useful.

Wading gear is essential. Felt-soled waders or boots with aggressive tread prevent slipping on silt. Bring a wading staff if you're unfamiliar with the bottom. A small tackle bag or backpack keeps your gear organized and your hands free for wading. Sunscreen, insect repellent, and water are non-negotiable, especially in summer.

Lodging options are limited; the nearest motels are in Croswell or in Sandusky (about 20 minutes south). If you're making a day trip from the Detroit area, plan for a 90-minute drive each way.

There are no tackle shops in Croswell itself. The nearest dedicated fishing retailers are in Sandusky or Bad Axe, both 20 to 30 minutes away. Stock up on tackle and bait before you arrive, or plan to fish with what you bring. Some gas stations in Croswell may carry basic tackle and live bait, but selection is limited.

Frequently Asked Questions

Can I fish the Black River year-round?

Technically yes, but practically no. Winter water temperatures (30s to 40s) make fish sluggish, and ice can form on slower sections. Most anglers fish April through October. A few dedicated walleye anglers fish December and January, but access and success are both poor.

Do I need a boat to fish here?

No. Wading is the standard approach and often more effective than a boat because the river is narrow and shallow. A small canoe or kayak lets you cover more water, but scouting by foot first is wise to avoid fallen trees and low branches.

What's the best time of day to fish?

For smallmouth, early morning and late evening are most productive, but they bite throughout the day in spring and fall. For walleye, dawn, dusk, and night are best. Summer fishing is slowest during midday heat; focus on early morning and evening.

Where can I buy live bait near Croswell?

Bait availability is limited in Croswell itself. Call ahead to local gas stations or check with the Croswell village office for current options. Sandusky and Bad Axe, both 20 to 30 minutes away, have tackle shops with reliable bait selection. Bring your own if you're unsure.

Is the Black River good for beginners?

Yes. The river is wadeable, narrow, and holds fish that respond to basic techniques. Smallmouth are forgiving and bite a variety of lures. If you're new to walleye fishing, this stream is a reasonable place to learn, though walleye require more patience and often better timing than smallmouth.
