The Upper Deschutes is a Mosquito HELL now. Fishing is good though, so what is your tolerance? How will you prepare to overcome the swarm? 

I think this week we will see some Golden Stones up there. 

PMD’s and Caddis will be your main hatches, Ants and Beetles are always a good idea on a forest headwater river and if you want to lay the gauntlet down you tie on a Dark Walts, a Brown Jig Napoleon and a Black Jig Squirrel streamer and get after it.
