The East Walker is currently fishing good and should fish even better as soon as it warms up and the flows get bumped up. This will spread the fish out more and make for more diverse water to cover. Nymphing with PT's, Silver Streaks, WD-40's and zebra midges in the #18-20 range will work in the deeper pools and runs. As I said before this area is at a lower elevation and will see the influence of spring sooner than HC and the UO.
