Deschutes River: Big River Campground to Benham Falls Professional Review and Guide
"The first 7 miles to Harper Bridge wander very slowly, with houses lining the banks for most of the length. The next 6-mile section passes Sunriver with a noticeably stronger current and a large contingent of leisurely drifters. Below Sunriver, the Deschutes makes a rather dramatic geological transition as it passes around and over the many lava flows of this region.
After miles of mirrorlike water, the river is suddenly and violently churned into a frenzy at Benham Falls, a spectacular series of class 5+ ledges, holes, and froth, cascading more than a hundred feet in 0.5 mile. The normal take-out is on river right at the Benham Falls boat ramp, just above a footbridge over an impassable logjam. Character: forested; residential; resort country."
