Frequently Asked Questions

How is river flow measured?

River flows are measured in cubic feet per second (CFS). At levels above 20,000 CFS, many famous rapids are washed out while others such as Slide Rapid become unrunnable or extremely difficult. At levels between 19,000 CFS and 3500 CFS, there are plenty of fun and exhilarating rapids for all to enjoy. Wild River Adventures monitors river flows so that the safest possible experience can be had.

What are whitewater rapid classifications?

Whitewater classifications generally on an international scale of Class I through V with an occasional class VI.
Class I – Small waves, no serious obstacles, easily navigated.
Class II – Medium waves, clear passages, minimal maneuvering.
Class III – Numerous large or irregular waves, rocks, eddies, narrow passages, and occasional scouting are suggested.
Class IV – Powerful, irregular waves, boiling eddies, dangerous rocks, technical passages, and precise maneuvering required. Scouting recommended.
Class V – Exceedingly difficult, violent rapids, often in quick succession, big drops, erratic currents, and waves; scouting is strongly recommended but may be difficult.
Class VI – limited navigability, usually considered unrunnable.

Are there historical sites along the river?

There are sites where pictographs and man-made structures from past communities are evident. There is a lot of history about his area and its indigenous people and others who traveled or settled in the region.

What do I bring for a float trip?

If your float trip is a half-day or a full-day trip, you will only need the clothes you prefer to wear on the river, a swimsuit or shorts and a shirt, hat, sunscreen, and a water bottle. In cooler weather, Wild River Adventures will provide wetsuits and splash jackets. You are required to wear life jackets provided by Wild River adventures. Drinks and snacks are also provided on all trips. Full-day trips include lunch.

Multi-day trips will require more personal gear, and the packing list for these trips varies depending on the length of the trip. A packing list will be provided for the trip you plan to take

Licenses and permits

If you plan to fish or hunt, you will need the appropriate license issued by the state of Idaho. Licenses can be purchased online at No other permits are required. Special use permits are held by Wild River Adventures that provide access to the river.

Can we have a campfire?

Campfires are generally allowed in designated fire rings in approved campsites. If camping on the river, we are required to have fires in specially designed fire pans that elevate the fire off the ground, and the ashes must be carried out with other garbage.

What precautions are taken in case of emergencies?

All guides are trained in CPR and First Aid. Each boat is equipped with a first aid kit. Each group carries one trauma kit and a Spot GPS signaling device. There is limited cellular coverage in the river corridor. Most half-day trips and full-day trips are close to roadways, and help can be obtained quickly from passing motorists if necessary.

How is trash handled?

We pack out everything that we pack in.

How is human waste dealt with?

Solid waste is packed out in approved portable toilet systems. It is acceptable to urinate in the river or on the wet sand. Urinating anywhere else attracts insects and creates odors. On most half-day and full-day trips, this is not an issue. Multi-day trips carry the appropriate equipment.
