Horseshoe Lake

On the LakeGrade scale Horseshoe Lake grades a B, with clarity at 10.0 ft and phosphorus readings still being added placing it above the Minnesota median. 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.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. Horseshoe Lake reaches 24 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. Horseshoe Lake covers 121 acres alongside 2.5 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Horseshoe Lake ranks 4 of 17 in Todd County, putting it in the upper tier of locally monitored lakes.

No invasive species are currently listed at Horseshoe Lake — the lake remains off the Minnesota infested-waters roster. The fishery includes walleye alongside the lake's other 11 documented species — a notable draw for Minnesota anglers. Public access is available — the lake is on the Minnesota PCA public-access list. Ice-out has been recorded 7 times at Horseshoe Lake, with a median around Apr 15. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
