The Crooked River is a solid choice now for you and unless something really extraordinary happens with snow pack we are not going to have a big dam release this winter or spring so plan on good water conditions for now.
Our old friend Drew-Who came back to Central Oregon and spent some days on the Crooked last week with his son and they had a lot of luck on Eggs and Zebra Midges.
Olive Perdigons, 2 Bit Hookers, Skinny Nelson, Fire Starter, Scuds, Midge Winker, Olive Mini Gulp and Slum Lords will get you through on the nymph side whether that is tight lining or with a NZ Wool indicator. Someone said that they caught fish on BWO’s on the Crooked, and I think with the mild winter that is certainly possible already. But midges in February are usually more prolific so keep that late afternoon hatch open for your best opportunity to dry fly fish now.
