Great places to fish if it gets snotty in the upper elevations. Tubing PV this time of year can be epic and you should have the option of fishing both still water nymph rigs along the drop-offs near the inlet, or trolling streamers with a full sink or heavy sinking tip line from the launch ramp towards the inlet. The river section can be awesome as well depending on power generation. You will know immediately in the parking area if the LADWP is moving water to turn the turbines. Hit the inlet on the REZ proper if it is on, fish the river if not. Dry/dropper combos with tigers & olive caddis larva work great here. The gorge is very good to fish this time of year as well. The wild browns can be ravenous here as the sun hangs lower. Most dries in the #14-18 range will get grabs. I continue to have success with a #16 Stimmie and a #18 bead head PT, or midge pattern.
