We hit Sprague lake on Sunday at around 0800 and started trolling J-9 orange bellied Rapalas close to the bottom on the downriggers. After 2 hours of no hits trolling close to the shore on the West end we moved to mid-lake and started zig zagging in the middle of the lake going from shore to shore and the bite was on mid afternoon. in 1.5 hours we had our limit of 2 fish each over 20 inches the largest was 24 inches with bright red fillets on all 4 fish. Trolling speed was 1.4 to 2.0 mph. These fish put up a great fight.
