The Clark Fork River begins near Warm Springs and flows for 275 miles where it empties in to Lake Pend Oreille. The Clark Fork River is notorious for its opportunity's to cast to "pods" of large rising Trout. Fishing for Trout on this river can be divided into two sections above and below Missoula. The upper section is one of Montana’s medium sized rivers Brown Trout are predominate here. The lower section (this is where the "pods" of Trout are found) has big riffles long slow runs and deep holes. For something different one might want to throw on a streamer and go for a big Northern Pike.
