What Makes Rimrock Lake Different

Troll small spinners for kokanee over the old Tieton channel and cast small spoons for rainbow trout closer to creek mouths and shelves.
How Rimrock Lake Fishes
Rimrock is known for kokanee, but they may suspend well above the bottom. The upper Tieton arm becomes more riverlike as storage falls.
After the first bite on Rimrock Lake, note whether it came from moving water, rock, weeds, wood, or open water because that one detail is more useful than a broad report from another end of the lake and tells you what kind of feature to repeat nearby.
Keep Rimrock Lake's open-water fish and shoreline fish on separate passes because the main targets here include kokanee salmon, rainbow trout and cutthroat trout, and those fish do not all use the same cover, depth, or lure speed even when they are feeding in the same part of the lake.
Before leaving Rimrock Lake, compare the best feature at two nearby depths and change lure speed once so that short check shows whether the problem is the location or the presentation without turning the rest of the trip into random casting.
