Main Salmon River Idaho Flows, Rafting and Fishing

Rafting and fishing the main Salmon River is a dream trip. Located in Idaho, it’s a bigger version of the Middle Fork with more than 80-miles of rapids and big water fun. The campsites are great with big sandy beaches and float season is long, running well ahead of and after the lottery draw season. Wildlife is common in the river corridor and the float can run for 3-5 days depending on flows and personal preference.

Lottery Permit System

The main salmon river permits are issued through the 4 Rivers lottery system. Permits are issued for prime summer dates running between June 20 and September 7 but you can self issue permits before and after these dates. The prime dates are desirable however because groups are limited, ensuring a less crowded river with open campsites.

River Specific Fishing Regulations

The fish species are diverse and availability really depends on timing. During the heat of summer, smallmouth bass are abundant and there is no limit on these fish. Anglers often catch them at will when the bite is on and they are good for eating as well.

The limit for trout is 6 and only those with a clipped adipose fin. You must release all cutthroat trout. Keep in mind, these regulations only apply to the main stem and not the tributaries.

Chinook Salmon and Steelhead also run the river. Steelhead are generally present after the main floating season and most anglers focus efforts upriver where day floats are an option. The salmon fishery is different each year. If the run is strong, a short season may open. Slow years will see closures however.

Rafting the Main Salmon River is something every paddler and angler should consider. It’s a great lottery option for summer floats and the logistics aren’t overwhelming outside of the very long shuttle.
