The Crooked River is still fishing well on nymphs throughout the afternoon and I don’t see any super cold air settling on top of us, so I expect to keep seeing open water and decent to good days of fishing. 
Scuds, Zebra midges, Perdigons, 2 Bit hookers, Skinny Nelsons, Rainbow Warrior are great winter patterns here. 
As you are ready to pack up for the day, look for midges to be hatching further down and out of the steepest canyon areas in the flat water areas. Mile post 12 is a good example of what I am talking about. Midge Winkers and Griffiths Gnats and Century Drive Midges are good on 6.5 or 7x tippet. It is a fun last stop if the fish are up.
