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.
