Lake Mohawksin

The LakeGrade rubric puts Lake Mohawksin at a C: clarity at 4.0 ft, 35 µg/L of phosphorus, and a TSI of 56 signal an intermediate trophic state. The two scored sub-grades — clarity and phosphorus — track close together, so neither one is dragging the average down.

At a TSI of 56, Lake Mohawksin reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. Lake Mohawksin reaches 25 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 1,515 acres, Lake Mohawksin is one of the larger lakes in Lincoln County, with partial shoreline records supporting multiple distinct use patterns. Lake Mohawksin ranks 15 of 18 in Lincoln County — at the lower end of the locally monitored distribution.

Lake Mohawksin carries an invasive watermilfoil record — boat-launch decontamination and shoreline care matter more here than at uninfested lakes. The fishery includes walleye among the lake's 6 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.
