JC Boyle Bypass Flows

JC Boyle Dam

The portion of the Klamath River natural channel between JC Boyle Dam and JC Boyle Powerhouse is commonly called the JC Boyle Bypass. Releases from the dam provide flow through this natural channel at all times of the year.

Flows may vary due to a variety of conditions, including weather, upstream flows and dam operations.

The flow release schedule for the J.C. Boyle Powerhouse is a good faith estimate and not a guarantee that any releases will occur as or when estimated. Operational considerations, mechanical failure, human error or system safety concerns could require changes to this schedule with little or no notice. PacifiCorp provides this information as a courtesy for recreational users of the river and makes no warranty of its accuracy or fitness for any particular purpose.

These flow estimates now include an additional 150-300 cfs of base flow occurs in the JC Boyle bypass reach between the dam and the put-in. It is recommended that all boating parties check the BLM staff gage at the put-in to verify actual flow.

The values listed above are in average cubic feet per second for the 60 minute period beginning with the hour indicated in the above table. Actual flows will vary over the hour when the project is ramping flows up or down.

These water management data are provisional readings of current river flow conditions. Beware and use caution since river flows can change dramatically because of operational changes at the dams or due to weather conditions.
