Fosdick Lake

Fosdick Lake earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade.

A TSI near 46 places Fosdick Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. 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. Fosdick Lake ranks 14 of 16 in Morrison County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Fosdick Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Fosdick Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Fosdick Lake — most use is by shoreline residents and their guests. 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.
