The Crooked River is fishing great. Nice flows, good access and great nymph action. Keep an eye open for Mother’s Day Caddis now. #14-16 Caddis pupa, emergers and adults. Brachycentrus Caddis are the family we call Mothers Day Caddis. They tend to trend towards a greyish-olive. But tan and sometimes black patterns are the better hatch matchers in different periods of the hatch. 
Scuds and Zebra Midges and Micro Mayflies are the hot nymphs for the moment. 

Blue Wing Olives are slowing down but can be important as a dry fly on any given day, but year round importance for the BWO/Baetis Nymphs #18-22.
