Whitewater Boating

Our 2011 license to operate the Jackson Hydro Project includes a provision to provide an average of three opportunities for whitewater boating per year. Scheduled events, which occur in the spring (typically April), late summer (August), and early fall (September), will have two weeks' advance notice. 


The summer/fall 2020 whitewater boating releases have been postponed due to COVID-19 social distancing/public health obligations. The next whitewater boating opportunity will be scheduled when it is safe to do so. Water for postponed events will be banked for use in future event(s).

Boaters should pre-register indicating intent to participate in our whitewater boating event. Please pre-register with your name, address, phone number, and email address below (all fields are required). If the event is cancelled due to limited interest (pre-registration of less than 6 individuals), you will be notified by phone or email.

Before you participate, you must fill out, sign and return the PUD Whitewater Release form (see Related Documents to the right). Completed forms must be delivered to the PUD staff person, stationed at the put-in location, on the day of the event. Upon receipt of a completed form, you will be issued a numbered, yellow wrist-band. This wrist-band is required and mandatory for all persons intending to participate in the event.

Sultan River Access

Vehicle access is available on the Culmback Dam Road to the Gateway Trailhead. From there, you can hike for a mile to the trailhead for the new Sultan River Canyon Trail. From the trailhead, it is another mile to the river and kayak put-in location at river mile (RM) 15.5.

Put-in and take out access is also available at the Powerhouse (RM 4.5) and at PUD’s property at Trout Farm Road (RM 2.7).     

Another put-in and take-out option exists at the Diversion Dam; however, due to safety and logistical concerns, this alternative must be approved and coordinated with the PUD, City of Everett, and American Whitewater staff well advance of any whitewater event.
