I do not understand why the Crooked is up to about 300 CFS. Seems like a waste of water we will need for the fall and winter. I have heard mixed reports on the fishing, from very good to not that great. Everything I have heard lately had revolved around fishing small midge and mayfly nymphs with Euro style or with a little yarn NZ indicator. 
Perhaps an early season lull in the action? We’ve seen it before on the Crooked in June so I am sure it will bounce back soon.
