We hit both the upper and lower yesterday, found a couple fish. Lost some fish. Usual winter. You can go out for an hour or two and probably pick up one or two fish, that would be a good outing this time of the year. Streamer fishing has been productive, heavy sink-tips, get your bug down, short 2-3" strips with a little pause through the deep slack water pools, or eddies. Nymphing a stone / prince, or worm has been good too. Get them deep in the slow water. Warmest part of the day is best. Good place to fish right now for a couple hours.
