The Warm Springs to Trout Creek section of the Lower Deschutes is fishing well too. Nice afternoon fishing in the eddies and under the trees on a smorgasbord of spent and crippled mayflies and caddis. In the evening you’ll get the hatches of Caddis the Lower Deschutes is famous for, plus some Pale Evening Duns and likely some PMD’s too.
Iris Caddis and Parachute Caddis with a Fluorescent Post are dandy in the evening for fooling fish, but also for being able to see the darn things. X Caddis, Rusty and Yellow Spinners, Yellow Knock Down Duns, Spent Partridge Caddis, Silvey’s Dead Caddis, Sparkle Pupa, Poopah, Soft Hackle and a variety of Euro Nymphs have been great for us.
BTW, August is a good month to try grasshoppers on the bank lines. A lot of hoppers there and for some reason the Lower D never got much of a hopper following. I know its not the epic hopper fishery some western rivers are, but it is certainly worth the time to work some of those grassy and rip-rap banks with a juicy hopper now.
Some of my guides have been going with the trout spey and swinging streamers too.
Steelheading is poor, and water conditions at the mouth are not going to improve any this week with yet another heat wave coming tomorrow. Give the steelhead a break and get up river and fish for trout.
