About this run

Madison River

The Madison River, located in Montana, is a popular destination for whitewater rafting enthusiasts. The ideal streamflow range for this river is between 2,500 and 4,000 cubic feet per second (cfs) to ensure a thrilling yet safe ride. The class rating for the Madison River varies throughout its length, ranging from Class I to Class IV. The segment mileage for the whitewater section of the Madison River is approximately 20 miles, starting at the town of Ennis and ending at Bear Trap Canyon.

There are several specific rapids and obstacles to watch out for when rafting on the Madison River. One of the most challenging rapids is called Kitchen Sink, which is a Class IV rapid with a steep drop and a large boulder field. Another notable rapid is called the Ruby Creek Rapid, which features a series of large waves and boulders.

There are several regulations in place to ensure the safety of both rafters and the environment. For example, all flotation devices must be Coast Guard approved and properly fitted to each person on the raft. Rafters must also follow strict guidelines regarding waste disposal and are required to pack out all trash and debris. In addition, the river is closed to boating during the winter months to protect the local wildlife and their habitat.

Overall, the Madison River offers a thrilling and scenic whitewater rafting experience for those who are properly equipped and prepared. It is important to follow all regulations and guidelines to ensure a safe and enjoyable trip.

Whitewater safety

Check the flow before you run
Use the linked-gauge card and Regional Flow panel above. Class ratings change with flow -- a Class III at low water can become Class IV+ at high water.
Know your skill ceiling
Pick runs comfortably below your ceiling. Cold-water and big-water runs raise the consequences of any mistake.
Wear the right gear
Helmet, PFD, drysuit / wetsuit when water is below 60°F. Throw bag, knife, and whistle on your person, not in the boat.
Scout, set safety, and run with a team
Scout new rapids on foot, set safety with throw bags above the consequence pool, and run with at least one other competent paddler.
Respect the river
Strainers, undercuts, low-head dams, and wood can kill at any class rating. When in doubt, portage.

Set push alerts in the Snoflo app

Save Madison River as a favorite, set a discharge threshold (e.g. "alert me when flow hits 600 cfs"), and the iOS app pushes the moment the linked gauge crosses.
