Currently the reach from Pioneer Park to JC Boyle Dam is inundated beneath the waters of a reservoir. From JC Boyle Dam to the Powerhouse the river is regularly dewatered with flows bypassed through a canal and penstock as part of the hydropower project. You'll be lucky to catch this run with water in it as it only
happens when the reservoir is spilling. When that occurs, this run
makes a great five mile run with more challenging whitewater and
dramatic scenery than the Hell's Corner 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 you can enjoy 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 and again in 2020. Hopefully we'll see the day when the river once
again provides boating opportunities and improved conditions for the

On Thursday, April 4th, the Department of Interior recommended removing four dams on the Klamath River, listing the action as the Preferred Alternative for a long-term solution to address native fishery and water resource issues in the Klamath Basin. The recommendation was set forth in the Department's Final Environmental Impact Statement (EIS), which provides a comprehensive review of whether partially or fulling removing four dams owned and operated by PacifCorp will help to restore salmon runs to the Klamath River.
A public comment period is now open for the restoration of the Klamath River through November 21st. Secretary of the Interior Ken Salazar announced in late September that the federal government has completed numerous peer-reviewed scientific and technical studies providing new and detailed information about the environmental and economic impacts of removing four Klamath River hydroelectric dams.

flow and access tips, and maps associated with runs you've done. You can even add new
runs to the inventory!
