The Pend OReille river is a tributary to the Columbia river. It is a mixed species river, with trout bass, panfish, and pike. The river level fluctuates and is controlled by the Box Canyon dam. Of note, the Pend OReille has been in the spotlight for it's pike population, seen by many anglers as a great sportfish, but seen by the WDFW as an invasive species which needs to be greatly reduced. Netting policies have caused for strained relations between WDFW and many sport anglers.
