Lawrence Lake

On the LakeGrade rubric, Lawrence Lake pulls an A: clarity at 26.2 ft and phosphorus readings still being added put it in the top bracket for Wisconsin. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

A TSI value of 30 puts Lawrence Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. The lake bottoms out at 47 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. Lawrence Lake is small — 50 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Among the 32 graded lakes in Langlade County, Lawrence Lake ranks 8 — in the top quartile locally.

Lawrence Lake has at least one documented invasive species (Chinese Mystery Snail), so boaters and anglers should observe clean-drain-dry steps when leaving the lake. The fishery includes walleye alongside the lake's other 4 documented species — a notable draw for Wisconsin anglers. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
