Kings Lake

Stearns County, MinnesotaEutrophic

Kings Lake sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. A maximum depth of 44 ft puts Kings Lake in the middle of Minnesota's depth distribution. The lake's 204 acres and 3.1 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Kings Lake sits at rank 28 of 55 in Stearns County, in the lower half of the local distribution.

No invasive species are currently listed at Kings Lake — the lake remains off the Minnesota infested-waters roster. Walleye are documented at Kings Lake, one of 15 fish species on record for the lake. A documented public access point at Kings Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Ice-out has been recorded 22 times at Kings Lake, with a median around Apr 12. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.

From the 2025-08-25 survey

A targeted survey of nearshore fish species in Kings was conducted on August 25-August 27, 2025, by Lake Biological Monitoring and Assessment Program (LBMA) staff. Sampling sites were evenly spaced around the lake, and each was sampled by backpack electrofishing and seining with a 50-foot or 15-foot seine, where…
