Scout Lake
Florence County, WisconsinLimited DataOligotrophic
Scout Lake comes in at a B on the grading rubric — a respectable showing for a Wisconsin lake of its size and depth.
A TSI value of 39 puts Scout Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. The lake bottoms out at 26 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. At 24 acres, Scout Lake sits below the Wisconsin median: a small water where shoreline activity has an outsized effect on water quality. Scout Lake ranks 19 of 39 in Florence County — solidly in the upper half of the local distribution.
No invasive species are currently listed at Scout Lake — the lake remains off the Wisconsin infested-waters roster. Bass fishing is part of the appeal: the species list runs to 2, anchored by largemouth and/or smallmouth bass. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
