Tubing Pleasant Valley is a good bet trolling streamers near the launch ramp, and right near the transition from the river into the lake. There is very high flows in the river when the turbine is on so position yourself where the water slows down and there is less debris.

The Gorge is fishing great and flows here are stable. If you don't mind the hiking and rock hopping this is a good area to get into fish on the surface. Mayfly and caddis fly imitations #14-18 are good choices. Dry/dropper bead head nymph rigs work well also for the deeper runs and pools.
