Sturgeon River Kayaking Guide (Alger County)

Michigan has several rivers named Sturgeon, and this guide covers the one that flows through Alger County in the central Upper Peninsula — not the Sturgeon River of Baraga and Houghton counties, and not the West Branch Sturgeon River that is popular with paddlers in Dickinson County. The Alger County Sturgeon rises in the Hiawatha National Forest country and works its way south toward the Sturgeon River Sloughs and Big Bay de Noc on Lake Michigan. It is a quiet, lightly documented river, and this guide is honest about what is known and what is not.

The Michigan DNR references a handful of carry-in access points along this river: the 14-Mile Bridge (45.98949, -86.67988), Flowing Well Campground (45.93706, -86.70760), and the County Road 497 crossing (45.85095, -86.66917). These appear in DNR access inventories rather than in a published paddling route guide, which tells you something important about the character of this river: people do get boats on it, but nobody has written the definitive float plan. Expect a small, meandering, forest-lined stream where water levels dictate everything and downed timber is a constant companion.

The country the river passes through is classic central UP: second-growth hardwoods and conifers, state and national forest land interspersed with private parcels, and very few services. This is a river for self-sufficient paddlers who enjoy exploratory floats, carry a saw, and treat every bend as a potential portage. If that sounds like your kind of trip, the Alger County Sturgeon offers genuine solitude — you are unlikely to see another boat.

Paddling the Sturgeon River

14-Mile Bridge to Flowing Well Campground

The 14-Mile Bridge carry-in (45.98949, -86.67988) and Flowing Well Campground (45.93706, -86.70760) sit close together on the upper portion of the river documented by the DNR. This is small-stream paddling through forest country — intimate, shaded, and best attempted in spring or after sustained rain when the river carries enough water to float a kayak without constant dragging. Treat this as exploratory: scout from the bridge first, and be ready to turn around at the first impassable logjam.

Flowing Well Campground to CR 497

Downstream of Flowing Well Campground, the river continues south toward the County Road 497 crossing (45.85095, -86.66917). No reliable mileage or difficulty rating exists for this reach. The same rules apply: adequate water is everything, portages around strainers are mandatory, and private land along the corridor means you should know where you are welcome and where you are not. A folding saw and a willingness to get out and walk the bank are standard equipment here.

Below CR 497 toward the Sturgeon River Sloughs

South of CR 497 the river works toward the low, marshy country of the Sturgeon River Sloughs near Big Bay de Noc. The current eases and the channel can braid through wetlands — beautiful birding country, but also the kind of terrain where a wrong turn costs you an hour of backtracking. This reach is the least documented of all; consider it expedition paddling rather than a day float.

Hazards & Portages

Downed timber and strainers are the defining hazards on this river, along with seasonal low water that can turn a float into a hike. Beaver dams are likely in the slower reaches. Road crossings may have culverts that are not boat-passable. The remoteness of the corridor means slow rescue: paddle with a partner, file a float plan, and carry the Ten Essentials plus repair and first-aid gear.

Access & Parking

The DNR-documented carry-in points are the 14-Mile Bridge (45.98949, -86.67988), Flowing Well Campground (45.93706, -86.70760), and the CR 497 crossing (45.85095, -86.66917). These are unimproved carry-in sites rather than developed launches — expect roadside or campground parking and a carry to the water. Verify current conditions with the Michigan DNR or the Hiawatha National Forest before committing to a trip.
