Wilson Flowage Lake

Price County, WisconsinEutrophic

Wilson Flowage Lake sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. 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.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. At only 11 ft deep, Wilson Flowage Lake is shallow — wind keeps the water column mixed and sediment resuspension drives phosphorus levels harder to manage. The lake's 348 acres and partial shoreline records put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Within the 26 graded lakes of Price County, Wilson Flowage Lake sits at rank 25, near the bottom of the county list.

Eurasian watermilfoil has been documented at Wilson Flowage Lake, requiring shoreline management to keep dense mats from crowding native vegetation. Walleye are documented at Wilson Flowage Lake, one of 5 fish species on record for the lake. A documented public access point at Wilson Flowage 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.
