The Potlatch River is a hidden gem in northern Idaho, carving through scenic canyons as it flows approximately 56 miles from its headwaters in the Palouse Range to its confluence with the Clearwater River near Lewiston. This tributary of the Snake River system offers exciting whitewater opportunities for experienced paddlers, particularly in its remote middle canyon section. The river can be divided into three main paddling sections: the upper, middle (canyon), and lower reaches.

The upper section from Forks Road Bridge to Little Boulder Creek Campground provides a 3.6-mile Class I-III warm-up run. The highlight is the 15-mile middle canyon stretch from Little Boulder Campground to Cedar Creek, featuring continuous Class II-V rapids through a stunning basalt gorge. The lower 6-mile section from Cedar Creek to Kendrick offers more moderate Class II-III whitewater.

Paddlers should be prepared for a challenging wilderness experience in the canyon, with limited access points and the potential for wood hazards. The river's difficulty ranges from Class II to V, requiring solid whitewater skills and rescue knowledge. Early season runs often involve portaging ice in some sections. The Potlatch's flow is highly seasonal, with the best paddling typically occurring from late winter through spring (February to May). Flows can drop quickly, making the lower canyon very scrapy below 4 feet on the gauge. Summer temperatures in the canyon can reach the 80s, while winter paddling requires cold water gear.

The river corridor supports diverse wildlife, including steelhead, elk, and various bird species. Paddlers will be treated to impressive basalt cliffs, ponderosa pines, and the solitude of a deep canyon wilderness.

Key access points include Forks Road Bridge near Deary for the upper section, Little Boulder Campground for the main canyon run, and takeouts at Cedar Creek or Kendrick. Moscow serves as the nearest major town, about 40 miles west of the put-in.

Historically, the Potlatch River was important to the Nez Perce tribe and later played a role in early logging operations. Today, it offers a pristine paddling experience for those willing to brave its challenging waters.

Safety considerations include scouting blind corners, being prepared for remote wilderness travel, and checking for current wood hazards. Paddlers should be self-sufficient and prepared for difficult egress in case of emergency. While primarily used for day trips, multi-day adventures are possible by combining sections or including nearby rivers like the Clearwater. The Potlatch River rewards skilled paddlers with a thrilling journey through one of Idaho's most scenic and lesser-known river canyons.
