Weyers Lake

Weyers Lake pulls a D on the LakeGrade rubric — phosphorus loading and limited clarity hold it below the Wisconsin average. With clarity and phosphorus scored, the sub-grades cluster within a letter of each other, pointing to stable conditions rather than one specific stressor.

A TSI in the eutrophic range signals a lake doing what nutrient-loaded waters do — supporting an active algal community at the cost of clear water. The lake bottoms out at 32 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. The lake is compact at 6 acres, with partial shoreline records and little volume to buffer nutrient inputs. Weyers Lake ranks 16 of 18 in Manitowoc County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Weyers Lake — the lake remains off the Wisconsin infested-waters roster. The fishery is bass-led, with 2 documented species across the lake's records. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
