Turtle Lake

Turtle Lake sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year.

Mesotrophic conditions dominate at Turtle Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. Turtle Lake reaches 33 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. The lake's 108 acres and 2.7 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Turtle Lake ranks 104 of 120 in Crow Wing County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Turtle Lake — the lake remains off the Minnesota infested-waters roster. Bass fishing is part of the appeal: the species list runs to 8, anchored by largemouth and/or smallmouth bass. No formal public access is documented at Turtle 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.
