Little Lake Landing

Cook County, MinnesotaLimited Data

Little Lake Landing grades an F: water clarity, phosphorus, and chlorophyll-a all rate poorly, placing it among the most stressed lakes monitored in Minnesota. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

There is not yet enough seasonal data to settle the lake's trophic classification — the TSI window remains too narrow to call. 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. Little Lake Landing ranks 128 of 128 in Cook County — at the lower end of the locally monitored distribution.

Little Lake Landing is on the Minnesota infested-waters list for zebra mussels — boaters should follow clean-drain-dry protocols when moving gear to or from the lake. The state fisheries records do not list documented species for Little Lake Landing, which usually reflects a lack of formal fisheries survey work rather than an empty lake. A documented public access point at Little Lake Landing 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.
