What You'll Find at Algonac Boardwalk

The Algonac Boardwalk sits along the St. Clair River in the small town of Algonac, about 50 miles northeast of Detroit. It's a public walkway that runs along the riverbank and gives you direct access to fish from shore without a boat. The boardwalk itself is roughly a quarter-mile long, with railings and benches, making it one of the few developed fishing spots on this stretch of the St. Clair River.

The St. Clair River here is tidal and brackish — it connects Lake Huron to Lake St. Clair, so water levels and salinity shift with the seasons and weather. That mix of fresh and salt water creates habitat for both warmwater and coolwater species. The current can be strong, especially during spring runoff or after heavy rain, and the river bottom is mostly mud and silt.

Fishing from the boardwalk is free and open to the public year-round. You do need a Michigan fishing license to fish anywhere in the state, including from shore. The boardwalk is in downtown Algonac, easily accessible by car, with parking available nearby on the street or in small municipal lots.

Key Takeaways

  • The Algonac Boardwalk is a public shore-fishing spot on the St. Clair River that requires only a Michigan fishing license and costs nothing to use.
  • Walleye, smallmouth bass, and channel catfish are the main species here, with seasonal patterns that shift through spring, summer, and fall.
  • Spring and fall offer the most consistent fishing, when water temperatures and current patterns bring fish closer to shore.
  • The boardwalk is short and can get crowded on weekends, so early morning or weekday visits often mean more space and fewer interruptions.
  • Bring a net if you plan to land larger fish, and be prepared for strong current and slippery conditions after rain.

Species and Seasonal Patterns

Walleye are the most sought-after fish here. They move into shallower water during low-light periods — dawn, dusk, and overcast days — and they feed heavily in spring and fall when water temperatures drop. Summer walleye fishing from the boardwalk is slower because the fish move deeper into the river channel. Live shiners or small minnows work well, as do jigs tipped with minnow or crawfish. Walleye season runs year-round in Michigan, with no closed period on the St. Clair River.

Smallmouth bass are present spring through fall. They congregate around structure — rocks, pilings, and the edges where current breaks — and they respond to crankbaits, soft plastics, and live crawfish. Early summer (May and June) and fall (September and October) are peak times. Bass season is open year-round in Michigan as well, though winter fishing from the boardwalk is less productive.

Channel catfish are active from late spring through early fall. They feed at night and in low-light conditions, so evening and night fishing produces better results. Cut bait, chicken liver, and stink baits all work. Catfish don't require a lot of technique — cast out, set your rod in a holder, and wait. They're a good option if you want to fish passively while enjoying the river.

Summer (July and August) is the slowest season overall. Water temperatures rise, fish move deeper, and the boardwalk can be crowded with tourists. If you fish in summer, focus on early morning or late evening when it's cooler and quieter.

Access and Parking

Algonac is located on M-29, which runs north-south along the St. Clair River. From Detroit, take I-94 north to M-29 and follow it northeast toward the town. The boardwalk is in downtown Algonac, near the intersection of M-29 and River Street. Street parking is available along River Street and in small municipal lots nearby — there is no dedicated fishing lot, but spaces are usually available except on summer weekends.

The boardwalk itself is wheelchair-accessible and has benches spaced along its length. There are no restrooms directly on the boardwalk, but downtown Algonac has restaurants and shops within a short walk. The nearest gas and supplies are in town; there is no bait shop directly at the boardwalk, so bring your own or stop in Algonac before you arrive.

The boardwalk is open during daylight hours year-round. There are no posted fishing hours, but local practice and common sense suggest fishing from dawn to dusk. Night fishing is technically possible but not recommended because the boardwalk has limited lighting and the current is harder to read in darkness.

Tackle and Technique for Shore Fishing

Because the boardwalk is short and can be crowded, you'll want to fish efficiently and respect other anglers' space. A medium-action spinning rod (6 to 7 feet) with 8- to 12-pound monofilament or braided line works for walleye and bass. For catfish, a heavier setup (7 to 8 feet, 15- to 20-pound line) is better because you may need to horse a fish away from pilings or current.

Cast parallel to the boardwalk or slightly downstream, letting the current work your lure or bait. The river channel is close to shore here, so you don't need to cast far — 30 to 50 feet is usually enough. If you're using live bait, keep your rod tip up slightly to feel the current and detect bites. Jigs and soft plastics work well because you can work them slowly and feel the bottom, which helps you stay in the zone where fish hold.

Bring a small net if you plan to land fish larger than 15 inches. The boardwalk railings are high enough that netting a fish is difficult without one. A headlamp or small flashlight is useful for early morning or evening fishing, and polarized sunglasses help you spot fish and read the water during the day.

Regulations and Licensing

Michigan requires a fishing license for anyone 17 and older. You can purchase a license online through the Michigan Department of Natural Resources website, at sporting goods stores, or at some gas stations. A one-day license costs less than a full-year license if you're visiting for a short trip. Licenses are checked by conservation officers, and fishing without one carries a fine.

Walleye and bass have no closed season on the St. Clair River, but there are daily catch limits. Walleye has a limit of five fish per day (with a 15-inch minimum length), and smallmouth bass has a limit of five fish per day (with a 12-inch minimum length). Channel catfish have no size limit and a limit of 25 fish per day. These limits are current as of 2024 but can change, so check the Michigan DNR website before you fish.

The St. Clair River is shared with Canada, and some areas have special regulations. The boardwalk itself is clearly in Michigan waters, so Michigan regulations apply. If you're fishing from a boat and cross into Canadian water, you'll need a Canadian license — but from the boardwalk, this is not a concern.

When to Fish and What to Expect

Spring (April through May) is one of the best times. Water temperatures are rising, walleye and bass move into shallower water to spawn or feed, and the boardwalk is less crowded than in summer. Expect water levels to be higher due to snowmelt and rain, and current to be stronger. Dress in layers because mornings are cool.

Fall (September through October) is equally good. Water temperatures drop, fish feed actively before winter, and the boardwalk is quieter again. Days are shorter, so plan to fish early morning or late afternoon. Weather can change quickly, so bring a rain jacket.

Winter (November through March) is slow. Water is cold, fish are less active, and the boardwalk can be icy. Some anglers fish through the winter for walleye, but it requires patience and cold-weather gear. Summer weekends are crowded and fishing is poor, so avoid them if you can.

Nearby Alternatives and Facilities

If the boardwalk is too crowded or you want to explore other options, the St. Clair River has several public access points nearby. Algonac State Park, just north of town, has a boat launch and shoreline fishing. The park charges a day-use fee and has restrooms and parking. Harsen's Island, accessible by bridge south of Algonac, has public fishing areas and a quieter feel.

Algonac itself is a small working waterfront town with a few restaurants, a hardware store, and a marina. There is no dedicated fishing lodge or guide service, but marinas in town can point you toward local knowledge. The nearest larger town with more services is Port Huron, about 15 miles south.

Frequently Asked Questions

Do I need a boat to fish here?

No. The boardwalk is designed for shore fishing and requires no boat. You can walk out, set up, and fish from the railing. If you do have a boat, you can also fish the river channel nearby, but the boardwalk itself is for pedestrians only.

What's the best time of day to fish the boardwalk?

Early morning (sunrise to mid-morning) and late afternoon through dusk are best for walleye and bass because light is low and fish feed actively. Catfish are more active at night, so evening and night fishing works for them. Avoid midday in summer when the boardwalk is crowded and fish are inactive.

Can I fish here in winter?

Yes, but it's slow. Water is cold, fish are less active, and the boardwalk can be icy. Some walleye anglers fish through winter, but you'll need cold-weather gear and patience. Spring and fall are much more productive.

Is there a bait shop at the boardwalk?

No. Bring your own tackle and bait, or stop at a shop in Algonac before you arrive. The nearest full-service tackle shop is in Port Huron, about 15 miles south.

What should I do if I hook a large fish?

Bring a net. The boardwalk railings are high, and landing a fish without a net is difficult. Keep your rod tip up, let the current help tire the fish, and guide it toward the net slowly. If the fish runs toward pilings or structure, keep tension and be ready to adjust.
