Kibbee Lake

Clearwater County, MinnesotaMesotrophic

Kibbee Lake comes in at a B on the grading rubric — a respectable showing for a Minnesota lake of its size and depth. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.

Mesotrophic conditions dominate at Kibbee Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. 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. Within Clearwater County's 40 graded lakes, Kibbee Lake ranks 27 — below the local median, though not at the bottom.

No invasive species are currently listed at Kibbee Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Kibbee Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. Public access is available — the lake is on the Minnesota PCA public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
