Little Rice Lake

St. Louis County, MinnesotaLimited DataEutrophic

The LakeGrade rubric puts Little Rice Lake at a C: clarity readings still being added, 50 µg/L of phosphorus, and a TSI of 61 signal an intermediate trophic state.

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. Within St. Louis County's 187 graded lakes, Little Rice Lake ranks 131 — below the local median, though not at the bottom.

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