Southern Boundary Of State Land To Mouth
The Whitewater River Run Southern Boundary of State Land to Mouth is a popular river run in Idaho, offering a thrilling adventure for experienced kayakers and rafters. The ideal streamflow range for this run is between 1,500 and 3,000 cfs, as any higher or lower can make it too difficult or too dangerous to navigate.
This run is classified as a class III-IV, which means it has moderate to difficult rapids and requires skill and experience to navigate. The segment mileage of this run is 18.8 miles, starting from the southern boundary of state land and ending at the mouth of the river.
Some of the specific river rapids and obstacles that kayakers and rafters may encounter on this run include the Whitewater Falls, which is a 20-foot waterfall that requires careful navigation, as well as the Big Rocks Rapid, which has large boulders and fast-moving water.
There are specific regulations that must be followed in this area, including carrying a personal flotation device (PFD) for each person on board, as well as having a whistle and a throwable device on hand. Additionally, there are restrictions on the use of motorized boats and certain types of fishing equipment.

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.
