Uncompahgre River

The small bugs will still work, but flows have been bumped so make sure to try some bigger stuff like leeches and SJ worms with the midge and mayfly nymphs.
Perhaps, try a streamer or bugger for some aggressive eats as well.

Patterns/Bugs:
Midges 18-24: Sidewinder Midge Pupa, Tavs Big Mac, Jujubee Midge. Midge Dries: Duranglers Adult Midge, CDC Biot Midge, Midge Dry.
San Juan Worms, Red, Wine, Orange. Red and Orange Annelids, and Chamois leeches. Thread Baetis, Jujubaetis.
RS-2 Foam Wing Emerger #20-24, Killer Mayfly #22-24, Brown Baetis Nymph #20-24

Uncompahgre (98.6 cfs): While low for this time of year, this is an excellent fishing flow at Pa-Co-Chu-Puk State Park. Up until this point, midges have dominated the menu, but we expect the 3-month PMD hatch to begin any day. Technical presentations will be necessary to catch Pa-Co's wary trout throughout this hatch. On top, fish size #18 PMD patterns such as the Lawson's no hackle, Harrop's CDC patterns and AK's Melon Quill. Nymphs tied with glass beads or no beads at all are most effective, including the Mayhem, RS-2 variations and split back mayfly nymphs.

Its still small bug time but you can throw an attractor nymph or leech with a midge pupa behind and can find some fish!
Perhaps, try a streamer or bugger for some agressive eats as well.
