Yellowstone Park 9-11-12

If you are a Firehole River fan the cooling temperatures are just the ticket.  Look for BWOs there to begin emerging in good numbers, and with cooler water fish will respond.   Streamer fishing will also pick up all through the Park, especially where browns are moving.   Terrestrial insects remain in good numbers, but with hard frosts not far away their importance will soon diminish. So enjoy the last few weeks of big trout exploding on your hopper, beetle and ant patterns.
