Wintergreen Lake

On the LakeGrade scale Wintergreen Lake grades a B, with clarity at 10.5 ft and phosphorus readings still being added 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 43 places Wintergreen Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. Wintergreen Lake reaches 15 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. Wintergreen 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 27 graded lakes in Price County, Wintergreen Lake ranks 6 — in the top quartile locally.

No invasive species are currently listed at Wintergreen Lake — the lake remains off the Wisconsin infested-waters roster. The fishery is bass-led, with 3 documented species across the lake's records. 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.
