YELLOWSTONE RIVER
PREDOMINANT ACTIVITY, HATCHES & FOOD FORMS
APRIL 28TH THRU MAY I0TH
One of our most incredible caddis hatches of the year happens during this period. Often times, concentrations of these insects can be inches thick, literally blanketing the water surface. Runoff can be a factor during this hatch and usually brings an abrupt end to the excellent fishing sometimes during the first ten days in May.
