Limestone Lake

Limestone Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. Limestone Lake reaches 34 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. The lake's 234 acres and 5.0 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Within Wright County's 64 graded waters, Limestone Lake sits at rank 16, near the top of the local distribution.

Zebra mussel presence at Limestone Lake means the lake's clarity numbers carry an asterisk — filtered water is not the same as nutrient-poor water. Walleye are documented at Limestone Lake, one of 13 fish species on record for the lake. A documented public access point at Limestone Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. 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.
