Wiley Lake

On the LakeGrade scale Wiley Lake grades a B, with clarity readings still being added and 27 µg/L of phosphorus placing it above the Wisconsin median.

At a TSI of 52, Wiley 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. Within the 52 graded lakes of Bayfield County, Wiley Lake sits at rank 43, near the bottom of the county list.

Wiley Lake has no invasive species recorded in Wisconsin state databases as of 2025, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Wiley 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.
