What You'll Find at Grand Trunk Boat Launch

Grand Trunk Boat Launch is a public access point on the Rifle River in Ogemaw County, located near the town of West Branch in Michigan's Lower Peninsula. The launch serves anglers and recreational boaters heading into a river system known for smallmouth bass, walleye, and panfish. The facility itself is modest — a single-lane concrete ramp with limited parking — but it provides direct access to one of the region's more productive warmwater fisheries.

The Rifle River runs roughly 40 miles from its headwaters near Grayling south to Saginaw Bay. Grand Trunk sits in the middle section where the river widens and deepens, making it accessible to small to mid-sized boats. The surrounding landscape is a mix of state forest and private land, with the river corridor itself relatively undeveloped compared to many Michigan waterways.

Seasons and Best Times to Fish

Spring (May through June) brings the most consistent smallmouth bass activity as water temperatures warm and fish move into shallower areas to spawn. Early morning and evening trips during this window often produce the best results. Walleye fishing picks up in late May and remains strong through early summer, particularly around deeper holes and current breaks.

Summer (July and August) can be productive for both species, though midday heat pushes fish deeper and into shaded areas. Many anglers shift to early morning or dusk sessions. Fall (September through October) is excellent for smallmouth bass as they feed aggressively before winter; walleye also remain active in cooler water. Winter access depends on ice conditions — the river does freeze, but ice thickness varies year to year, so check local conditions before attempting winter fishing.

Species and What to Expect

Smallmouth bass are the most abundant gamefish in this section of the Rifle River. Fish typically range from 12 to 18 inches, with occasional larger specimens. They respond to crankbaits, soft plastics, and live crawfish. The river's rocky bottom and current structure provide ideal habitat.

Walleye are present and can be caught year-round, though they are less numerous than smallmouth. Evening and night fishing with live minnows or jigs produces the most consistent results. Panfish — bluegill, pumpkinseed, and rock bass — are abundant and provide good action for anglers using light tackle or fly rods.

Boat Types and River Conditions

The Rifle River in this section is navigable by small to mid-sized boats — typically 16 to 20 feet is ideal. Shallow-draft boats and jon boats work well. The river bottom is rocky and can be uneven; run at moderate speed and watch for submerged logs and debris, especially after heavy rain. Water depth varies from 4 to 12 feet depending on location and season.

Current is moderate and generally manageable for experienced boaters. During spring snowmelt or heavy rain, water levels rise and current increases; check conditions before launching. Canoes and kayaks can also access the river from this point, though paddlers should be comfortable with moving water and aware of occasional obstacles.

Regulations and Licensing

Michigan fishing licenses are required for anyone 17 and older. Licenses can be purchased through the Michigan Department of Natural Resources website, at sporting goods retailers, or at some bait shops. A recreational fishing license covers most freshwater fishing; a combination license includes hunting privileges if you need both.

Smallmouth bass and walleye have specific season dates and bag limits that vary by year. Check the current Michigan fishing guide before you fish — regulations change and are enforced. Panfish typically have generous bag limits and longer seasons. All anglers should carry their license on the water.
