Generation And Giant Gaps (Tadpole To Colfax-Iowa Hill Road)
The gaps are still expert runs but the river has calmed down some (compared to the Royal Gorge). There is still plenty of class IV and V to be had in here so this run is still for advanced boaters.
Suggested river levels for paddling this section of the American River, North Fork are between a bare minimum of 500cfs and a high of 2,500cfs.
