Access to Hosmer is uncertain in May. The lake is at the north end of the Cascade Lakes Highway, near South Sister, and winter leaves late in that area. Once the snow is gone and you can reach the lake, you may still find a little ice. But when you can get there and when the ice goes off Hosmer, the fish will go on a two-week feeding binge. You want to be there. The south end of the lake (near the boat ramp) warms up first, and that is where the early action will be. Midge patterns and damselfly nymphs (Dougs Damsel , Approximate Damsel , Marabou Damsel, etc.) should take fish.
