Alpine Lake

On the LakeGrade scale Alpine Lake grades a B, with clarity readings still being added and 23 µg/L of phosphorus placing it above the Wisconsin median. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

A TSI near 49 places Alpine Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. Alpine Lake reaches 18 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. Alpine Lake is small — 50 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Alpine Lake ranks 27 of 32 in Waushara County — at the lower end of the locally monitored distribution.

Eurasian watermilfoil has been documented at Alpine Lake, requiring shoreline management to keep dense mats from crowding native vegetation. The state fisheries records do not list documented species for Alpine Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. A documented public access point at Alpine Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. 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.
