Fay Lake

On the LakeGrade rubric, Fay Lake pulls an A: clarity at 23.0 ft and 16 µg/L of phosphorus put it in the top bracket for Wisconsin. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

The lake's low TSI puts it in oligotrophic territory — the cleanest of the four trophic classes, but also the most vulnerable to nutrient-driven shifts. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. At 272 acres, Fay Lake fits the Wisconsin median for monitored lakes, with partial shoreline records. Fay Lake ranks 11 of 39 in Florence County — solidly in the upper half of the local distribution.

An invasive species record — Banded Mystery Snail — has been logged at Fay Lake; Wisconsin DNR maintains the official infested-waters list. The fishery includes walleye alongside the lake's other 4 documented species — a notable draw for Wisconsin anglers. A documented public access point at Fay Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
