Moccasin Lake

On the LakeGrade scale Moccasin Lake grades a B, with clarity at 6.4 ft and 19 µg/L of phosphorus placing it above the Wisconsin median. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.

The lake sits in the mesotrophic zone — the band where most well-managed Wisconsin lakes fall. Moccasin Lake reaches 19 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 88 acres, Moccasin Lake sits below the Wisconsin median: a small water where shoreline activity has an outsized effect on water quality. Moccasin Lake ranks 63 of 134 in Oneida County — solidly in the upper half of the local distribution.

Moccasin 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. Walleye are documented at Moccasin Lake, one of 5 fish species on record for the lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
