Thompson Creek is located in North Idaho, near the town of Naples. This river run is best suited for intermediate to advanced kayakers and rafters and is rated class III-IV. The ideal streamflow range for this river is between 1,000 and 3,000 cubic feet per second (cfs).

The run is approximately 12 miles long and is broken up into two main sections. The upper section is about 6 miles long and has continuous rapids with some technical maneuvers required. The lower section is less steep and has larger waves and holes. There are several named rapids on the river, including "Pinball," "T-Bone," and "S-Turn."

One of the challenges of this run is the number of downed trees and strainers, which can create dangerous obstacles. It's important to scout the river before starting the run and to be aware of any potential hazards.

Specific regulations for the area include a required permit for overnight camping, as well as regulations on fire use and human waste management. It's important to follow Leave No Trace principles and to respect private property along the river.
