Kingfisher Lake

On the LakeGrade scale Kingfisher Lake grades a B, with clarity at 12.1 ft and phosphorus readings still being added placing it above the Minnesota median.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. A maximum depth of 42 ft puts Kingfisher Lake in the middle of Minnesota's depth distribution. Kingfisher Lake is small — 37 acres alongside 1.6 miles of shoreline — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Kingfisher Lake ranks 59 of 142 in Lake County — solidly in the upper half of the local distribution.

Kingfisher Lake has no invasive species recorded in Minnesota state databases as of 2021, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Kingfisher Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Kingfisher Lake — most use is by shoreline residents and their guests. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.
