The 49 mile stretch from The Dirty Devil/ Colorado River confluence to Bullfrog Bay/Marina is very dynamic. Conditions are constantly changing due to reservoir levels and the river’s sediment delta pushing into the reservoir “basin.” Due to continued deterioration of the North Wash Boat Ramp just downstream of the Dirty Devil River, it is more likely that Cataract Canyon river parties may choose to end their trip at Bullfrog. The above link provides some basic info for groups traveling through this area.
