The Clackamas River originates from Olallie Lake and flows through the Cascade Mountains before emptying into the Willamette River. Four sections of the Clackamas River are designated as Scenic Waterways. They include 12 miles of the North Fork, 4 miles of the South Fork, and the mainstem from Olalie Lake Scenic Area to North Fork Reservoir (54 miles) and from River Mill Dam to Carver, a distance of 12 miles.
The Clackamas River got its name from the Clackamas Tribe of Native Americans who once lived on the river. The Clackamas is the closest whitewater river to Portland - perfect for those on a time budget.
