Robinson Pond
Jackson County, WisconsinMesotrophic
Robinson Pond carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. Clarity is the limiting factor — phosphorus is reasonable but suspended particles or algal cells keep water transparency below Wisconsin norms.
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. Robinson Pond is small — 11 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Robinson Pond sits at rank 2 of 3 in Jackson County, in the lower half of the local distribution.
No invasive species are currently listed at Robinson Pond — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Robinson 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.
