Fairchild Pond
Eau Claire County, WisconsinMesotrophic
Fairchild Pond comes in at a B on the grading rubric — a respectable showing for a Wisconsin lake of its size and depth. 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.
The lake sits in the mesotrophic zone — the band where most well-managed Wisconsin lakes fall. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake's surface area is not consistently recorded across state datasets — physical context remains partial. Fairchild Pond ranks 1 of 3 in Eau Claire County — solidly in the upper half of the local distribution.
No invasive species are currently listed at Fairchild Pond — the lake remains off the Wisconsin infested-waters roster. 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. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
