The Crooked River is outstanding fishing and you can approach it a lot of ways. Try a swung Soft Hackle, fish the PMD hatch, Euro Nymph a Perdigon and Indicator fish with Micro Mayflies and Split Case Emergers. NZ Wool remains the #1 choice of indicator for this river with a small or micro OROS the next best indicator. 
In the evening there is a good Tan Caddis Emergence and at the right time and place you will see midges on the water and they can be important fish food in the moment. 
Perdigon colors include Olive, Orange, Brown, Pearl and Purple. Vary bead size and bead colors to match the water type and the light conditions.
