Rainbow Trout fishing at Blue Mesa Reservoir
Spring rainbow trout on Blue Mesa Reservoir hold shallow, usually 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 40 ft. The spot to know is Lake Gulch inflow, a inflow / creek mouth in about 17 ft of water that rates prime for rainbow trout in spring. Plan around early morning and the evening in the warm months.
