The Upper Deschutes is a mosquito Hell above Crane Prairie. They type of hatch where you’ll need not only bug spray but also a head net to not be driven crazy.
Fishing is good, so the prepared angler willing to navigate the aforementioned annoyance expect to catch fish on PMD, Drakes, Caddis, Ants, Beetles, Goldenstones and nymphs in the riffles and runs and streamers along the undercuts and log jams.
