Pickerel Lake

Pickerel Lake earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.

At a TSI of 54, Pickerel Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake's surface area is not consistently recorded across state datasets — physical context remains partial. Pickerel Lake ranks 50 of 62 in Oconto County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Pickerel Lake — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Pickerel Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. 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.
