The Crooked is still getting a big caddis hatch in the afternoon. A size 16-18 black caddis is the best match for the adults, and a Peacock Soft Hackle or Purple Soft Hackle has been our fly of choice for the Pupa. 
Some mixed mayfly hatches that may be important at the moment you are there include BWO, PMD and Mahogany Duns. 
Nymph fishing is excellent this time of year on Caddis Pupa, Zebra Midges, Split Case PMD, Micro May, Perdigons and Psycho Prince. Scuds are typically important and some days provide very good action.
