16-0569-00 Lake

The LakeGrade rubric puts 16-0569-00 Lake at a C: clarity at 9.5 ft, phosphorus readings still being added, and a TSI of 45 signal an intermediate trophic state. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. The lake's 95 ft maximum depth is in the upper tier for Minnesota — deep enough for cold-water fish to find refuge in summer. 16-0569-00 Lake covers 135 acres alongside 7.0 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Within Cook County's 128 graded lakes, 16-0569-00 Lake ranks 86 — below the local median, though not at the bottom.

No invasive species are currently listed at 16-0569-00 Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for 16-0569-00 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.
