Fleming Lake

Fleming Lake pulls a D on the LakeGrade rubric — phosphorus loading and limited clarity hold it below the Minnesota average.

A TSI in the eutrophic range signals a lake doing what nutrient-loaded waters do — supporting an active algal community at the cost of clear water. A maximum depth of 15 ft puts Fleming Lake in the middle of Minnesota's depth distribution. At 319 acres, Fleming Lake fits the Minnesota median for monitored lakes, with 3.6 miles of shoreline. Fleming Lake ranks 41 of 53 in Aitkin County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Fleming Lake — the lake remains off the Minnesota infested-waters roster. Bass fishing is part of the appeal: the species list runs to 11, anchored by largemouth and/or smallmouth bass. A documented public access point at Fleming Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The lake has a partial ice record — 14 observed ice-outs, centered near Apr 17. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
