Terrestrials (ants, hoppers) are still productive, but small midges are the most consistent way to get fish right now.

Pats Rubber Legs, sow bugs, CDC Pheasant Tail, pink worm patterns, Perdigons, Mole Flies, Mo Mercy Midge and Rs2s will work well.


Rocky Mountain National Park:

The flows in Rocky Mountain National Park are starting to get pretty skinny. The high country still has a few good weeks left in it. Moraine Park, Fall River, N St Vrain and Glacier Creek are fishing well. There is good action starting mid morning. Mayflies, midges, drakes and ants are producing good activity.

Hot Flies:  Small Parachute Adams, Red Double Downs, Mighty Mites, Red Two Bit Hookers, and Quasimodo Pheasant Tails are good options but so are San Juan Worms and Egg patterns.
