Pertinent Information

There are three lakes that make up the Blue Lake complex, one large lake and two smaller ones. The main larger lake has an average depth of 24 feet and a maximum depth of 44 feet. It is 24 surface acres, while the lower lake complex is 7.4 surface acres. Fish include brook trout, tiger trout (brown trout x brook trout hybrid), bowcutt trout (rainbow trout x cutthroat trout hybrid), and rainbow trout. Anglers generally average about 5 fish per day. The best times of the year to fish are in the summer and fall. When fly fishing, use standard late season nymph patterns such as damsels, but black leeches and green scuds also do good. Bait fishing is successful using Power Bait and worms. During early afternoon, spinners and metallic flatfish have consistent good luck. Blue Lakes lie in a Federal Wilderness Study Area, access is by a 1/4 mile hiking trail. Camping is primitive around lake. Blue Lakes are one of the most beautiful spots to fish in Nevada and within a short distance of Onion Valley Reservoir and Knott Creek Reservoir.


500 fingerling rainbow trout, 2,000 fingerling bowcutt trout, and 1,500 fingerling tiger trout are scheduled to be stocked by helicopter in summer.


Season is open from the second Saturday in June through November 15, any hour of the day or night. Limit is 5 trout. Only boats without motors are permitted.
