Kennedy Lake
Becker County, MinnesotaEutrophic
Kennedy Lake sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. 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.
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. Kennedy Lake ranks 77 of 93 in Becker County — at the lower end of the locally monitored distribution.
No invasive species are currently listed at Kennedy Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Kennedy Lake, 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.
