Little Sand Lake

Little Sand Lake sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. A maximum depth of 39 ft puts Little Sand Lake in the middle of Wisconsin's depth distribution. Little Sand Lake is small — 94 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Little Sand Lake ranks 17 of 37 in Barron County — solidly in the upper half of the local distribution.

Little Sand Lake has no invasive species recorded in Wisconsin state databases as of 2026, though prevention practices still apply at all access points. The fishery is bass-led, with 4 documented species across the lake's records. A documented public access point at Little Sand 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.
