Early Season Wisconsin Small Stream
If you ain't right down deep ticking the bottom and losing a few flies you are probably not where the fish are.
Use some bead-head (tungsten)flies and even add weight to the leader of need be to get down deep.
Czech Nymphing and tight line methods usually pay off for me when the water is high.
I'd think about a sink tip line and fairly hefty wooly buggers or streamers. And skip any water that isn't at least waist deep. Fish the flies as S-L-O-W-L-Y as possible
For me, it's still the thinest diameter I can reasonably fish, fished as slowly as I can fish. Lures are the same old: marabous, rapalas, and spinners (not as often). And a personal preference is single, barbless hooks regardless of season.
