Dickens Lake
Beltrami County, MinnesotaMesotrophic
On the LakeGrade rubric, Dickens Lake pulls an A: clarity at 11.0 ft and 15 µg/L of phosphorus put it in the top bracket for Minnesota. The two scored sub-grades — clarity and phosphorus — track close together, so neither one is dragging the average down.
The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. 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. Dickens Lake ranks 43 of 92 in Beltrami County — solidly in the upper half of the local distribution.
No invasive species are currently listed at Dickens Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Dickens Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.
