Flat River

A designated Natural River — shallow, quick, and scenic from Greenville to Lowell

The Flat River carries a special designation: it is one of Michigan's Natural Rivers, protected for its beauty and character. Flowing from the Greenville area southwest through Belding and Lowell to join the Grand River, it is a shallow, quick-moving stream that paddlers describe as laid-back but never boring. Reviews call it great for family trips and beginners — "a take an easy float, enjoy the day kind of river" — while also noting the current runs fast enough that paddling upstream is real work (one group took two hours to paddle up and 42 minutes to float back).

Scenery is the Flat's strong suit. The river passes beneath historic covered bridges, through the Flat River State Game Area, and past Fallasburg Park — one of the prettiest county parks in West Michigan. Between Greenville and Belding the river stays nicely cleaned out, and the stretch from Belding down to the village of Smyrna is a classic 2- to 4-hour tube or kayak float. Expect turtles, herons, and eagles along the banks.

At a Glance

• Approximate length: ~50+ miles of paddleable river, Greenville to the Grand River
• Difficulty: Beginner to easy intermediate — shallow with a quick current
• Water character: Shallow, clear, quick-moving; occasional deep holes
• Best season: May through September; spring flows are best, late summer can be bony

Paddling Sections

Greenville → Belding

Put-in: Greenville dam / downstream access  |  Take-out: Belding dam portage access  |  Distance: About 11–12 miles of river

The upper classic: put in below the Greenville dam and float through the Flat River State Game Area (Bricker Road access sits about midway at the Montcalm–Ionia county line). The state keeps this reach nicely cleaned out. Take out at the developed dam portage below Belding — a good rest stop and put-in/take-out point.

Belding → Smyrna

Put-in: Belding  |  Take-out: Village of Smyrna  |  Distance: 2–4 hours of floating

The favorite casual float: launch in Belding and drift down to Smyrna. Beautiful scenery, usually not crowded, and an easy shuttle. Tube, kayak, or canoe — all work well here.

Fallasburg Park → Lowell

Put-in: Fallasburg Park (42.9859, -85.3291)  |  Take-out: Lowell boat ramp  |  Distance: About 6 miles

A lovely afternoon paddle. Two miles in, the river widens into the backwaters of the Burroughs Dam — it feels like paddling across a lake — then the dam's well-marked portage on the right lets you carry a few hundred feet back to the river. The last four miles are easy and scenic, ending at the Lowell boat ramp on the left, just upriver from the showboat, as the Lowell skyline comes into view.

Hazards & Portages

Three dams require portages on the paddled reaches: the Greenville dam, the Belding dam (developed portage), and the Burroughs Dam near Lowell (well-marked portage on the right). The river's quick current and shallow spots are the other main challenge — you may scrape or briefly ground in low water, and the current near the Burroughs Dam release can push paddlers toward the banks when flows are high. As a designated Natural River, the banks are largely undeveloped: beautiful, but with few bailout points, so plan your trip length carefully.

Access & Parking

Public access is limited mostly to road crossings and dam sites, per the state's natural river plan. Key points: the Greenville dam access, Bricker Road in the Flat River State Game Area, the Belding dam portage, Fallasburg Park (Kent County park with parking, restrooms, and the covered bridge area), and the Lowell boat ramp. Respect private land — stay in the river corridor and use only designated access sites.
