Melon Lake

The LakeGrade rubric puts Melon Lake at a C: clarity at 8.5 ft, phosphorus readings still being added, and a TSI of 46 signal an intermediate trophic state.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake's surface area is not consistently recorded across state datasets — physical context remains partial. Within Lake County's 142 graded lakes, Melon Lake ranks 97 — below the local median, though not at the bottom.

Melon Lake has no invasive species recorded in Minnesota state databases as of 2022, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Melon Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Melon Lake — most use is by shoreline residents and their guests. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
