About Main Salmon

Permits are required year-round to float the Wild section of the Salmon River, from Corn Creek to Long Tom Bar. The lottery control season runs June 20 through September 7, and during it no more than eight float boat parties - commercial and non-commercial combined - are allowed to launch each day. Outside the control season the number of launches is unlimited, but you still need a trip permit before launching. A maximum of 30 people is allowed per group, with trip length scaled to it: 1 to 10 people up to 8 days and 7 nights, 11 to 20 up to 7 days, 21 to 30 up to 6 days. Outside the control season the group cap stays 30 and the maximum trip length is 10 days. Fees are a $6 non-refundable reservation or lottery application fee plus a $4 per person per day special recreation fee, with a 50% reduction on the per-person fee for Senior or Access Pass holders. The lottery takes applications from December 1 at 8:00 am Mountain Time through January 31 at 11:59 pm MT. Results post February 14, successful applicants must confirm by March 15 at 11:59 MT, and anything declined, cancelled or unaccepted releases on March 16 at 8:00 am MT. After that, cancellations are randomly released within 24 hours. Required equipment is specific: a portable toilet, fire pan, fire blanket, ash container, shovel, bucket, mesh strainer and the appropriate aquatic invasive species stickers. The Forest Service spells out a metal fire pan of at least 144 square inches with 3-inch sides, carried even if you do not plan on having a fire, an ash container carried on the same basis, and a mesh strainer fine enough to filter coffee grounds. The portable toilet must have enough capacity for the group; no wipes, sticks or rocks go in it. Bag systems are only acceptable for self-contained kayak groups or as a day potty, and WAG-bag style systems for self-support trips must be carried in a waterproof hard-shell container. Every boat must be clean, drained and dry on arrival, carry an Idaho AIS sticker, and - this is the part people miss - all watercraft must be inspected by Forest Service staff before going into the river.

The Wild section of the Main Salmon runs from Corn Creek to Long Tom Bar through the heart of the Frank Church-River of No Return Wilderness. It is the classic multi-day family river in Idaho: big enough water to be interesting, forgiving enough that the Forest Service describes it as a moderate to fast-paced whitewater floating experience rather than a technical one, and long enough that eight days feels earned.

The Experience

Wide beaches, warm afternoons, and a canyon that gets deeper as you go. Around 10,000 people float this section each year and it still feels empty, because only eight parties launch a day and everyone is moving in the same direction at the same speed.

The Forest Service publishes the run as 79 miles of free-flowing river between Corn Creek and Long Tom Bar. Note the boundary: the permitted section ends at Long Tom Bar, not at the road take-outs further down. From North Fork, Idaho, you turn off Highway 93 onto the Salmon River Road, Forest Road 030, and follow it 47 miles to the Corn Creek launch.

Trip length is tied to party size: 1 to 10 people get up to 8 days and 7 nights, 11 to 20 people up to 7 days, and 21 to 30 people up to 6 days. Outside the control season the maximum group is still 30 but the trip can run 10 days.

The agency publishes no whitewater class rating and names no rapid on the Wild section - so neither will we. What it does publish is that the experience is moderate to fast-paced depending on flow, and that when water levels exceed 5.0 feet at the Corn Creek gauge you can cancel three days out without a late penalty.

Permit Requirements

A permit is required year-round to float the Wild section between Corn Creek and Long Tom Bar

During the June 20 to September 7 control season, no more than eight float boat parties may launch per day

Maximum group size is 30 people

Trip length by party size: 1-10 people up to 8 days, 11-20 up to 7 days, 21-30 up to 6 days

Required equipment: portable toilet, fire pan, fire blanket, ash container, shovel, bucket, mesh strainer and AIS stickers

Fire pans must be metal, at least 144 square inches with 3-inch sides, and carried even if you do not plan to have a fire

All watercraft must be inspected by Forest Service staff prior to going into the river

Each boat must carry an Idaho Aquatic Invasive Species sticker and arrive clean, drained and dry

Gear & Preparation

Required Gear

  • A portable toilet with capacity for the whole group, and a strict no-wipes rule
  • A metal fire pan of at least 144 square inches with 3-inch sides
  • An ash container, carried whether or not you plan a fire
  • A mesh strainer fine enough to filter coffee grounds
  • Shovel, bucket, and an Idaho AIS sticker on every boat

Recommended Gear

  • A fire blanket - the Forest Service lists it as recommended and says it may be required in future
  • Sand stakes for securing rafts on the beaches
  • A hard-shell container for any bag waste system
  • A dry suit or splash gear for early-season flows

Hazards & Safety

High water. Above 5.0 feet at the Corn Creek gauge the agency lets you cancel three days out without penalty, which tells you what it thinks of those flows

Remoteness - this is the heart of the Frank Church-River of No Return Wilderness and help is a long way off

Scheduled infrastructure maintenance affecting access to and from the river; delays and closures should be expected

Long shuttle logistics on 47 miles of river road

Sun and heat on open beaches through midsummer

Best Time to Visit

The control season, June 20 to September 7, is when the river is metered and the beaches are usable. Early in it means higher water and pushier rapids; August and early September mean warm days, low water and easy camping. Outside the control season permits are still required but launches are unlimited.

Pro Tips

1

Apply as a small group. Ten people or fewer buys you eight days on the water; twenty-one or more cuts you to six.

2

Build the boat inspection into your launch-morning schedule. It is mandatory here, unlike on several neighbouring rivers.

3

Watch the Corn Creek gauge. Above 5.0 feet you can cancel three days out without a late penalty, which is worth knowing before you commit a shuttle.

4

Carry the fire pan and ash container even if you plan to cook on a stove - the requirement is unconditional.

5

Cancellations release randomly within 24 hours after March 16, so check often rather than once.
