With the warmth the last few days things are picking up with new hatches and more terrestrials. PMD’s have started to pop, some flying ants are showing (but I believe it will be the NEXT warm spell they really fly), ant’s, beetles, caddis and still some March Browns and BWO’s and Midges.
All that said, they don’t rise all day and there won’t be rising fish all day either. Look for risers mid day and again in the evening.
The rest of the time hit ’em on the head with small, heavy weight nymphs.
