Sand Lake

Sand Lake comes in at a B on the grading rubric — a respectable showing for a Wisconsin lake of its size and depth. The two scored sub-grades — clarity and phosphorus — track close together, so neither one is dragging the average down.

Mesotrophic conditions dominate at Sand Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. 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 Barron County's 37 graded waters, Sand Lake sits at rank 9, near the top of the local distribution.

No invasive species are currently listed at Sand Lake — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Sand Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. 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.
