Manor Woods Pond
Olmsted County, MinnesotaLimited DataEutrophic
Manor Woods Pond earns an F: phosphorus readings still being added and clarity at 2.5 ft signal heavy nutrient loading from the surrounding watershed.
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's surface area is not consistently recorded across state datasets — physical context remains partial. Manor Woods Pond ranks 5 of 5 in Olmsted County — at the lower end of the locally monitored distribution.
No invasive species are currently listed at Manor Woods Pond — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Manor Woods Pond, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The lake lacks a documented public access point, so visitor use is limited. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
