Fairchild Pond

Eau Claire County, WisconsinLimited DataEutrophic

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

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake is compact at 18 acres, with partial shoreline records and little volume to buffer nutrient inputs. Fairchild Pond ranks 1 of 3 in Eau Claire County — solidly in the upper half of the local distribution.

Fairchild Pond has no invasive species recorded in Wisconsin state databases as of 2020, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Fairchild 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.
