Crooked River is a very good place to be right now, and it has been most of the season. There have been mayfly hatches, mostly PMD’s now but so far midges and caddis are the top hatches, and with that probably the best bets for your nymphs will be zebra midges, cased caddis, caddis pupa, scuds and certainly split case PMD, micro may’s, perdigons, fire starter and soft hackles. 
Water levels are below the summer average, running at 181 CFS today. Reservoir is above 50% capacity but we might be seeing some tough conditions later in the fall? For now, fishing is very good and some really good trout arte being caught on nymphs and dries.
