River Description

Shorter runs are possible. Normally this is broken down into at least three sections.

At the end of this run where the Clackamas joins the Willamette River at Clackamette Park, a park-and-play feature has emerged at the boat ramp on the Clackamas River where a surf wave forms at the right tide and flow conditions (look for flows of 900-1200 cfs and a minus tide). 

Primary Access Points include:
McIver Park (river mile 21)
Paradise Park (river mile 20)
Barton Park (river mile 14)
Carver Boat Ramp (river mile 8)
Clackamette Park (river mile 0)

Clackamette Wave

Class - II+ Mile - 0
Rapid Thumbnail Missing
A park-and-play feature in Clackamette Park. It forms during periods of low flow when the Clackamas River is below 1200 cfs and the stage height of the Willamette River is under 3 ft. The wave forms two to three hours prior to low tide (less than 3 ft) and remains surfable for up to an hour later. During a normal season, this happens from late July through October/November.
