This water is managed as a cold water fishery. Splake have done very well in this lake and are the primary target of local anglers. Rainbows and Atlantic salmon, although present in good numbers, tend to be quite elusive. Smallmouth bass are abundant with fish up to 20" not uncommon. Yellow perch have been reported over 12" although the average is closer to 8".
