Bobberdown, float fishing for Steelies is deadly in the right water. They kill em in Canada doing that. One popular "bait" under the bobber is the PINK 6" bass worm. Thread the leader through the worm to within an inch of the bottom. Then let your #1 or #2 hook hang loose at the bottom. Deadly. Various jigs with sandshrimp are good too. They used to get them w/that on the Methow till NMFS closed it down permanently.
Another great February trout spot is O'sullivan Reservoir at the mouth of the wasteaways or East end of Lind Coulee. Big three year old hogs from Mar Dons 160,000 fish yearly planting stage there in Feb.to try to spawn in the wasteaways.

Can't divulge the location/Name of Secret lake due to blood oath and besides that Zen will hunt me down and kill me if I do.Much too small for much pressure, but the Resevoir has lots of Feb. trout and scads of room.
