If you’re headed to the Owyhee make sure and bring Tricos, they are working in mornings until the sun hits the water (around 10:30an to 11am). Big terrestrials are also working (beetles, hoppers, & ants), make sure and target the cut banks & fast ripple runs. Throughout the day, Callibaetis, PMD’s, & Midges are working.
On the sub-surface game you can also use nymphs. Try the little stuff like zebras, hares ear & split case PMD’s. Do a full nymph rig or a dry dropper. The streamer fishing is good as well.
