Army Lake

Army Lake comes in at a B on the grading rubric — a respectable showing for a Wisconsin lake of its size and depth. Secchi readings are the weakest of the three parameters, suggesting suspended sediment or algal biomass dominates the optical signal.

The lake sits in the mesotrophic zone — the band where most well-managed Wisconsin lakes fall. Army Lake reaches 17 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. Army Lake is small — 80 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Army Lake ranks 13 of 35 in Walworth County — solidly in the upper half of the local distribution.

Army Lake is on the Wisconsin infested-waters list for zebra mussels — boaters should follow clean-drain-dry protocols when moving gear to or from the lake. Bass fishing is part of the appeal: the species list runs to 3, anchored by largemouth and/or smallmouth bass. Public access is available — the lake is on the Wisconsin DNR public-access list. 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.
