YELLOWSTONE RIVER
PREDOMINANT ACTIVITY, HATCHES & FOOD FORMS
JUNE 26TH THRU JULY I0TH
The fabled Stonefly hatch begins during this period. June days are usually still marked by runoff. Depending on snow pack levels and weather conditions, runoff can also present a problem during the first week in July. If the water level is dropping and visibility is good, fishing can be at its best.
