69-0620-00 Lake

69-0620-00 Lake pulls a D on the LakeGrade rubric — phosphorus loading and limited clarity hold it below the Minnesota average. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

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 54 ft maximum depth is in the upper tier for Minnesota — deep enough for cold-water fish to find refuge in summer. 69-0620-00 Lake is small — 66 acres alongside 1.8 miles of shoreline — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. 69-0620-00 Lake ranks 177 of 187 in St. Louis County — at the lower end of the locally monitored distribution.

69-0620-00 Lake has no invasive species recorded in Minnesota state databases as of 2024, though prevention practices still apply at all access points. The state fisheries records do not list documented species for 69-0620-00 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.
