Shamrock

Shamrock Lake is a 56 acre lake in the Superior National Forest. The maximum depth is 13 feet and it has fairly clear water. The lake is located a mile south down USFS Rd. 386 (Kelly Loop Road). Access to the lake is a 600 foot carry-in trail to the southwest end of the lake beginning at fire #1657. Open water angling is most suitable for anglers with a canoe or float tube. Cold water temperatures and good oxygen levels are essential factors in Brook Trout growth and survival. To assess these important criteria, three automatic temperature loggers were deployed at the deepest water location in the lake at depths of 5, 8, and 12 feet from June 20 to October 15, 2018 and dissolved oxygen checks were conducted throughout the summer at the same location. The results of this investigation indicated that Shamrock Lake currently maintains suitable water temperatures and dissolved oxygen concentrations to sustain a stream trout fishery. Shamrock Lake currently supports a game fish community of Bluegill and Largemouth Bass. The purpose of this investigation was to assess the suitability of the lake for potential Brook Trout stocking. Summer dissolved oxygen and temperatures were not limiting factors in Shamrock Lake in 2018 but fell outside the range of ideal conditions for trout. These parameters will continue to be carefully monitored in future investigations to monitor the suitability of Shamrock Lake for Brook Trout stocking.
