Yellowstone Park

Choice of best fishing now is pretty much down to either top water with BWOs at such as the Firehole, Gibbon and Madison River and the Lamar River drainage or streamer fishing for migrating browns or bows. For browns the current best waters are Madison, Lewis, and Snake rivers. The Gardner River will kick in later in the month. Want a still water break from this? About the middle of this month Trout Lake will kick in. The biggest cut-bow hybrids in Park waters reside here. Another is to wade Lewis Lake shoreline and pitch streamers while wearing well insulated waders.
