Re: Patterns for Frying Pan, Roaring Fork & Colorado in late October?
Mysis, midges, bwo, pmd, and emergers
Midges, small stones, baetis, and bwo
Mayfly, small stones, midge and baetis
Also, don't be afraid to sling some streamers. October is brownie spawning time and they get aggressive. Although late october might be too late, but I would still have some handy if nymphing isn't working.
There will typically be a midge hatch or bwo hatch on the Pan and Fork depending on the weather. Think small. size 22, 24 dries or rs2's fished in the film will work.
