J.C. Boyle Powerhouse to State Line with California
Open all year. Catch rates are high during low flow periods. Flows are mostly high during the day. Best fishing is before 10 a.m. or after 6 p.m.
Best fishing is when flows are less than 900 cfs. Flow estimates are available and you can check them at PacifiCorp Weekly Flow Estimates. You can also call the flow line at 1-800-547-1501. Flows will lower this week on Wednesday until late afternoon. Fishing can be excellent this time of year if flows are fishable. Blue winged olive mayflies are hatching, which will provide some nice match the hatch dry fly fishing. The mayflies typically hatch from noon until four. Look to the backwater eddies and foam lines for rising fish.
Large attractor flies such and wooly buggers, bead head prince, stimulators, and rubber leg stoneflies under a strike indicator work best this time of year. Olive and black wooly buggers almost always work well. Black spinners and Panther Martins can also work.
Below the JC Boyle Powerhouse the redband/rainbow trout get slightly larger than the aforementioned reach and average 12 inches but rarely exceed 16 inches. Currently, most redband caught are in the 10- to 14-inch range.
