South Fork - Lower Section

1405 Hollipark Dr.
Idaho Falls, Idaho 83401
Water Type


The final section of the South Fork expanse extends from Byington to Menan, and based upon the opinions of the expert guides in the area, is the “most technical section”� on the river. The runoff debris coupled with stumps and logjams and numerous side channels that vary from year to year severely test the float skills of the best fishermen.

A bonus in this section is the abundance of brown trout in far greater numbers than in the two upper sections. Below Twin Bridges, the spectacular scenery that marks the entire expanse of this quality fishery continues as the river begins to widen as it flows through farmland.
