YELLOWSTONE NATIONAL PARK
PREDOMINATE ACTIVITY, HATCHES & FOOD FORMS
SEPTEMBER THRU 1ST SUNDAY OF NOVEMBER
Early in this period the Yellowstone River and its tributaries continue to receive most of the attention. Terrestrials and smaller mayfly or midge imitations produce well at this time. As we progress further toward and into autumn, however, fishing emphasis switches to the Firehole and Madison Rivers. The Madison has a great fall run of both brown and rainbow trout out of Hebgen Lake. Streamers and a variety of large nymphs tend to produce best on these fall running trout. Along with cooler weather, the Firehole turns on once again. Fall blue winged olives hatch in good numbers under ideal conditions. Heavy overcast with a little (or a lot) of rain or snow falling with little or no wind constitutes ideal conditions. Those conditions are usually associated with the best fishing on the Madison as well. Much to the disappointment of a few hard-core anglers, the season closes after the first Sunday in November.
