Cool weather has Mayfly activity a bit behind but everyday now more bugs are emergening. Depending upon the river system-Suplurs, Henricksens, BWO’s & Caddis are present. The cool evenings have been making hatches short-insects will come out -then temps drop & they disappear! Houdini Mayflies! Despite the lack of Mayfly activity Trout fishing I would rate as excellent over the past week. Cloud cover has provided for some prime opportunities during mid-day hours over the past week. If they are not feeding up top-give them something to munch on below the surface. The next week the forecast is looking considerably warmer-one would assume that the dry fly fishing is going to happen very soon! This slow warm up should provide for a great summer of Fly fishing here in the U.P.!
