Ice Slough river run
Ice Slough
Ice Slough is a popular whitewater river run located in the state of Wyoming. The ideal streamflow range for this run is between 150 and 600 cfs, which usually occurs during the spring and early summer months. The class rating for this section of the river is Class III to IV, meaning it is moderately difficult and requires some technical skills to navigate. The segment mileage for Ice Slough is around 3.5 miles, which typically takes about 2 hours to complete.
There are several notable rapids and obstacles along the Ice Slough run, including Big Kahuna, Widowmaker, and Hell Hole. These rapids are known for their steep drops, tight chutes, and powerful hydraulics, making them a thrilling challenge for experienced kayakers and rafters. It is important to note that the water in this area can be very cold, especially during the early part of the season, so proper gear and safety precautions are essential.
In terms of regulations, Ice Slough is managed by the Bridger-Teton National Forest and is subject to specific rules and guidelines. There are restrictions on camping and fires in the area, and visitors are required to pack out all trash and waste. Additionally, boaters are required to have a properly fitting personal flotation device (PFD) and to follow all navigational rules and regulations. Overall, Ice Slough is a beautiful and challenging river run that requires skill and respect for the natural environment.

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 Ice Slough 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.
