Little Sand Lake

Little Sand Lake sits at the top of the Wisconsin DNR grading rubric with an A, a mark reached by the cleanest lakes in Wisconsin. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Trophically, Little Sand Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. At 71 acres, Little Sand Lake sits below the Wisconsin median: a small water where shoreline activity has an outsized effect on water quality. Little Sand Lake ranks 11 of 48 in Washburn County, putting it in the upper tier of locally monitored lakes.

No invasive species are currently listed at Little Sand Lake — the lake remains off the Wisconsin infested-waters roster. The fishery includes walleye alongside the lake's other 4 documented species — a notable draw for Wisconsin anglers. Public access is available — the lake is on the Wisconsin DNR public-access list. 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.
