Fireside Lakes

Rusk County, WisconsinEutrophic

The LakeGrade rubric puts Fireside Lakes at a C: clarity at 3.7 ft, 25 µg/L of phosphorus, and a TSI of 54 signal an intermediate trophic state. 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, Fireside Lakes 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. At 211 acres, Fireside Lakes fits the Wisconsin median for monitored lakes, with partial shoreline records. Fireside Lakes sits at rank 7 of 12 in Rusk County, in the lower half of the local distribution.

Fireside Lakes has at least one documented invasive species (Chinese Mystery Snail), so boaters and anglers should observe clean-drain-dry steps when leaving the lake. The state fisheries records do not list documented species for Fireside Lakes, which usually reflects a lack of formal fisheries survey work rather than an empty lake. A documented public access point at Fireside Lakes 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.
