Cutthroat Trout fishing at Bob Lake
Start shallow in spring: cutthroat trout sit in 3 to 15 ft that time of year. By summer they slide out to 10 to 35 ft, and by winter most fish are in 10 to 40 ft. Break off the point is the standout, a drop-off at roughly 32 ft, rated prime for summer cutthroat trout. Plan around early morning and the evening in the warm months.
