Flows and temps are dropping on the upper D, but fishing remains good. Dry/Dropper rigs are still finding plenty of fish. Concentrate on deeper holes in the mornings, but fish will start to move around once the water begins to warm. Watch for hatches of caddis, BWOs, and midges.

So the fishing over on the lower D is hit or miss. You may be walking a lot for a few fishbut they will be good fish. When you find one trout, you may find a few. Fishing may pick up closer to the dam.
