The Crooked River is a gem now and worth fishing. Great opportunity for a Euro Nympher especially, and with good dry fly action most afternoons and evenings you should enjoy a lot of good fishing here. Pale Morning Duns #16 are the main hatch, but we are seeing BWO’s #20 and Mahogany Duns #16 and Tan Caddis #16. 
Fire Starter, Split Case PMD, Micro May’s, 2 Bit Hooker, Orange Psycho Prince, Scuds, Zebra Midges and Perdigons in Purple #18, Olive #16-18, Brown #16-18, Green #18 and Pearl #16. You can fish any of these nymphs under a Hopper or smaller Chubby, or under a small Oros Indicator.
