Over the past 20 years, there has been a lot of change in middle-lower Cataract Canyon. From Imperial Canyon (river mile 200) and below, rapids that haven’t been seen in decades are showing their teeth. Some of this is influenced by the current level of Lake Powell, the amount of river flow, and how much the river has carved back into its pre-dam historic river channel.

Currently, there are rapids in the lower part of Cataract Canyon that are not on any modern published river maps.

We offer a river map supplement as a way to both inform river runners of what to expect and help us all speak the same location-related language.

Our intent is to keep folks updated with current rapid information, campsite conditions, and what to expect at the North Wash Boat Ramp.
