Lake Mohawksin

On the LakeGrade scale Lake Mohawksin grades a B, with clarity at 13.1 ft and 35 µg/L of phosphorus placing it above the Wisconsin median. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

A TSI near 48 places Lake Mohawksin in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. 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 17 of 21 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 alongside the lake's other 6 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.
