Warm River, ID

Warm River is a spring fed river.  That makes this 26 mile live    water extremely clear with water temperature at 50 degrees year around providing excellent habitat for native trout.  The Warm River rises in the Caribou-Targhee National Forest, along  the western border of Yellowstone National Park.  In its upper reaches, it fishes like a small mountain stream.  At the Warm River Spring, it dramatically changes into something that most would call a modest river.  Approximately 200 cubic feet per second of that 50 degree water gushes out of an ancient volcanic aquifer and cascades down a hillside, greatly expanding the stream.  From this point down to its junction with the Henry’s Fork, the Warm River averages 25 to 50 feet wide and is excellent to wade and fish.
