The Rapids Return: Inside the Grand River Restoration in Grand Rapids
A slab of scarred limestone, pulled from the riverbed this summer, is the closest thing we have to a photograph of the rapids that named this city.
No one alive has seen the rapids. They went under the dams more than 150 years ago, before anyone thought to point a camera at them, and for a century and a half the only record was the city’s own name. Then, earlier this summer, crews clearing part of a downtown dam lifted out a chunk of limestone with circles and channels worn into its face — flow paths cut by fast water that stopped running decades prior.
That stone is one small piece of the Restoring the Rapids project, the effort now visible to anyone walking the riverfront: the fenced staging yard at Ah-Nab-Awen Park, the heavy equipment in the channel, the piles of pale boulders waiting their turn. It reads as a construction site, and it is one. What’s being built, though, isn’t a structure so much as a sound — the return of whitewater to the center of Grand Rapids for the first time in a hundred years.
A Name We Almost Lost
The dams went up when logging and furniture-making ran the city, and they served the industry of their day. They also flattened the river’s fast water, buried the boulders, and cut off the fish that once moved freely through downtown. For generations the Restoring the Rapids effort has been a promise more than a place: a vision that took public shape when it was founded in 2009 and gained momentum around 2012, when the nonprofit behind it began meeting with residents and city leaders about a healthy, reachable river running through the center of the city. Later, through the city’s River for All planning, more than 18,000 community members were invited to help reimagine what the Grand could be.
But the path from vision to construction was not always direct. In 2023, state regulators rejected the proposed design, citing concerns about the amount of material being placed in the riverbed and the engineered features intended to create recreational whitewater. The city withdrew its permit application and returned to the drawing board. A revised plan reduced the project’s footprint while retaining its central aims: removing four low-head dams, restoring habitat, and bringing the sight and sound of rapids back downtown. The state approved that plan in late 2024, hoping to still offer a return of something the region had been missing.
Built to Look Like It Was Never Built
The design goal became almost paradoxical: engineer the river so carefully that it looks like no one touched it. Four low-head dams between I-196 and Fulton Street are coming out, replaced with natural rock structures — boulder arches, constructed riffles, emergent habitat boulders, and bank vanes — arranged across nearly 2,900 feet of channel. More than 125 scattered boulders are being set to break up the flow and rebuild the kind of pocket water, seams, and micro-eddies that a wild river makes on its own.
Project manager Michael Staal has described the finished stretch as long and gradual, natural enough that fish won’t notice the difference. The boulder arches curve back and forth in a serpentine line, and the pools between them run deep, giving fish a place to rest as they move upstream. That matters for species the river has struggled to support, such as lake sturgeon, river redhorse, and snuffbox mussel. The fast water and slow water woven together do quiet, useful work: better oxygenation, more habitat, a healthier river top to bottom.
The care extends to the machinery itself. The excavators working in the channel run on vegetable-based hydraulic fluid, so a leak won’t poison the water they’re trying to heal. Turbidity curtains keep silt from drifting downstream. State permits held in-river work until July 1, timed so that low water at the Sixth Street Dam would keep invasive sea lamprey blocked while the work went on.
The Work of Waiting
A river doesn’t rebuild on a construction schedule. The work moves in seasons, shaped by water levels, weather, and permits. Ah-Nab-Awen Park closed in May to become the main staging ground and stays shut through the project, though the Gillett Bridge overhead remains open to anyone who wants to watch. In-river construction runs roughly July through November, pauses over winter, and picks back up in 2027, when the remaining dams come out.
What’s underway now is only the Lower Reach, or the first phase. A separate Upper Reach effort near the Sixth Street Dam, focused on sea lamprey control and fish passage, is still moving through federal review. This is a project that was nearly two decades in the planning before a single boulder moved, and the patience isn’t incidental.
The boulder drop structures near the Blue Bridge, by the Grand Rapids Public Museum, are already in and already running. So next time you cross downtown, take the long way past them and stop for a minute. The rapids uncovered in that scarred piece of limestone are no longer just a memory pressed into stone. Instead, they’re back in the water and getting louder by the week.
