Honey Lake
Walworth County, WisconsinEutrophic
On the LakeGrade rubric Honey Lake fails the cutoffs — a TSI of 67 and persistent algal pressure put it in the bottom tier. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.
Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. Honey Lake is a shallow lake at 6 ft maximum depth, which means it warms quickly, mixes constantly, and amplifies nutrient inputs. Honey Lake is small — 40 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Honey Lake ranks 33 of 35 in Walworth County — at the lower end of the locally monitored distribution.
Honey Lake carries an invasive watermilfoil record — boat-launch decontamination and shoreline care matter more here than at uninfested lakes. Bass fishing is part of the appeal: the species list runs to 5, anchored by largemouth and/or smallmouth bass. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
