Sand Lake

Sand Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Mesotrophic conditions dominate at Sand Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. A maximum depth of 28 ft puts Sand Lake in the middle of Wisconsin's depth distribution. The lake is compact at 23 acres, with partial shoreline records and little volume to buffer nutrient inputs. Among the 39 graded lakes in Florence County, Sand Lake sits at rank 15, above the county median.

Sand Lake has no invasive species recorded in Wisconsin state databases as of 2023, though prevention practices still apply at all access points. The fishery is bass-led, with 2 documented species across the lake's records. Public access is available — the lake is on the Wisconsin DNR public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
