Rabbit Lake

Crow Wing County, MinnesotaMesotrophic

Rabbit Lake sits at the top of the Minnesota PCA grading rubric with an A, a mark reached by the cleanest lakes in Minnesota. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

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. Among the 120 graded lakes in Crow Wing County, Rabbit Lake sits at rank 59, above the county median.

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