If you do buck conventional wisdom and head to the Jefferson, concentrate on the bigger runs below riffles and experiment until you find the right water speed and depth. Nymphing will be the best producer, and as a rule, expect very slow and subtle strikes, so make sure to set the hook on even small disturbances to your indicator. Slowly swimming a streamer across these runs can also produce some monsters, but probably less overall action. A big sculpin or woolly bugger is a good choice as a top fly when nymphing, and a prince or pheasant tail will do just fine as a dropper.
The Month Ahead:
Still not ideal. Wait till April.
Long Term Fishing Forecast:
The Jefferson is not known as a winter fishery, but some good spring fishing over the skwala stonefly can be had in the early spring.
