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. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. Kingfisher Lake reaches 42 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 37 acres, Kingfisher Lake sits below the Minnesota median: a small water where shoreline activity has an outsized effect on water quality. Kingfisher Lake ranks 61 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. The lake lacks a documented public access point, so visitor use is limited. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
