Mccormic Lake

Stearns County, MinnesotaLimited DataEutrophic

Mccormic Lake pulls a D on the LakeGrade rubric — phosphorus loading and limited clarity hold it below the Minnesota average. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. 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. Mccormic Lake ranks 46 of 55 in Stearns County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Mccormic Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Mccormic Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. A documented public access point at Mccormic Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. 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.
