With 550 cfs coming out of Mackay Dam wading remains tough in the river below. Best fishing is in or on just below Copper Basin right now. Look for caddis, PMDs, sallys, golden stonefly and traditional dry patterns to bring action.
Water flow gage just below Mackay Dam has a recent profile that looks like Monument Valley. Right now flow is around 660 cfs, but in the last few days it has varied from 400 cfs to 1300 cfs. Not good for fishing!
