The fishing on the Crooked continues to be great. The PMD hatch is starting to wind down, though Caddis are still available. Look for hatches of BWO's and Midges as well. The water level will drop once irrigation season is over (Mid to late October) The lower water level will consolidate fish even more. The whitefish spawn is another event to look forward to during the late fall and early winter months. Small egg patterns can be very productive during this time.
Trout fishing is great right now on the Deschutes. Most anglers are targeting steelhead though.
Great dry fly fishing can be had on spent caddis, craneflies, and small baetis. Watch for casual risers in back eddies, along banks, and under the Alders, use stealth tactics when stalking these fish.
Steelhead are present through the whole river. Fishing ranges from slow to good. Good numbers of fish are upriver from Warm Springs to South Junction. Fish are spread out and seem to be podded up through out the rest of the river. Cover lot's of water in your search.
