Picked from recent reports for this stretch.
Blue-Winged Olive Comparadun
Fall BWO hatches are critical, especially on overcast days like today. This low-profile dry fly is excellent for selective trout keying on emergers and adults.

Buy at AmazonWoolly Bugger (Olive)
A highly versatile streamer, the olive Woolly Bugger effectively imitates leeches and baitfish, making it excellent for stripping or swinging through deeper pools and runs to target aggressive trout.
Stimulator (Yellow)
This large attractor dry fly effectively imitates golden stoneflies or larger terrestrials, drawing aggressive strikes from trout in the faster waters of the Upper Sacramento River during summer.
Zebra Midge
Midges are the most prolific and consistent food source in the Upper Sacramento during February. Black or red versions in sizes 18-22 are essential for winter nymphing rigs.
Buy at AmazonMother's Day Caddis
The prolific Mother's Day Caddis hatch is expected in late April through May, making this dry fly a perfect imitation for adult caddis.
