    Roosevelt Lake is a Montana mountain lake supporting cutthroat trout, rainbow trout, and lake trout in the cold, clear water typical of Montana's productive high-country lakes. It represents the outstanding diversity of Montana's cold-water fisheries, where multiple trout species occupy different temperature zones within a single lake. Spot Features: Roosevelt Lake is a Montana mountain lake supporting a diverse cold-water fishery of cutthroat trout, rainbow trout, and lake trout. Cutthroat and rainbow trout are targeted with small spinners, flies, and bait near the surface, lake trout are pursued by trolling deep-running lures or jigging in the deeper basin. Check MFWP for current regulations. Seasonality: Cutthroat trout, rainbow trout, and lake trout are active year-round at Roosevelt Lake in Montana, with the best fishing in spring after ice-out and in fall when water temperatures cool. Cutthroat and rainbow trout are most active near the surface in spring and fall, lake trout stay deeper in summer. The lake may be ice-fished through winter.
