Cty E Pond

Cty E Pond sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. 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. At only 6 ft deep, Cty E Pond is shallow — wind keeps the water column mixed and sediment resuspension drives phosphorus levels harder to manage. Cty E Pond is small — 2 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Within Ozaukee County's 9 graded lakes, Cty E Pond ranks 6 — below the local median, though not at the bottom.

No invasive species are currently listed at Cty E Pond — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Cty E Pond, which usually reflects a lack of formal fisheries survey work rather than an empty lake. 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.
