Horseshoe Lake

Horseshoe Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. Secchi readings are the weakest of the scored parameters, suggesting suspended sediment or algal biomass dominates the optical signal.

Mesotrophic conditions dominate at Horseshoe Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. A maximum depth of 19 ft puts Horseshoe Lake in the middle of Wisconsin's depth distribution. Horseshoe Lake covers 113 acres alongside partial shoreline records — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Among the 37 graded lakes in Barron County, Horseshoe Lake sits at rank 11, above the county median.

Horseshoe Lake has at least one documented invasive species (Chinese Mystery Snail), so boaters and anglers should observe clean-drain-dry steps when leaving the lake. The fishery includes walleye among the lake's 4 documented species — a notable draw for Wisconsin anglers. 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.
