The Chain O' Lakes' end-of-season powerboat rally — a full day of boats, good times, and great people on the water. It's a rally, not a race. If it floats and it's insured, it's welcome.

River Rumble is the Chain O' Lakes' end-of-season powerboat rally — one last run together before the boating season wraps up!
We launched in 2025 and the first one was a huge success with close to 100 boats! In 2026, we're back and looking to make a splash again with a route that includes running the river and the lakes, with stops at some of the best destinations the Chain has to offer. Captains run their own boats and make their own calls; we pick the route and coordinate the stops.
The River Rumble Facebook group is where everything lands: itinerary updates, check-in details, sponsors and gear, weather calls, and photos from the day. Invite your boating friends, and see you on the water.
