Moose Lake

On the LakeGrade scale Moose Lake grades a B, with clarity at 7.9 ft and 21 µg/L of phosphorus 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. Moose Lake is a shallow lake at 11 ft maximum depth, which means it warms quickly, mixes constantly, and amplifies nutrient inputs. At 48 acres, Moose Lake sits below the Minnesota median: a small water where shoreline activity has an outsized effect on water quality. Within Itasca County's 141 graded lakes, Moose Lake ranks 92 — below the local median, though not at the bottom.

No invasive species are currently listed at Moose Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Moose 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.
