River Description

This is the bypass reach between the JC Boyle Dam and Powerhouse, and you'll be lucky to catch this run with water in it. It only happens when the reservoir is spilling, but when that occurs this run makes a great five mile run with more challenging whitewater and dramatic scenery than the Hell's Corner run downstream. When it has water, this rarely-boated upper section makes a great extension to the Hell's Corner run.

There are nine distinct Class IV rapids in this section, some of which are as much as a half mile in length. At the higher flows of 1300 and 1600 cfs there are numerous play features to catch on the fly as well as several play spots with eddy service. The long rapids with steep horizon lines provide plenty of entertainment for river runners. Overall, this reach has a creek-like appearance in a basalt canyon with ponderosa pines.

American Whitewater worked with Pacificorp, local boaters, and outfitters to coordinate a flow release study on this reach during summer 2002. Hopefully we'll see the day when the river once again provides boating opportunities and improved conditions for the native fishery.
