Moose Lake

The LakeGrade rubric puts Moose Lake at a C: clarity at 2.0 ft, 29 µg/L of phosphorus, and a TSI of 60 signal an intermediate trophic state. Clarity is the limiting factor — phosphorus is reasonable but suspended particles or algal cells keep water transparency below Wisconsin norms.

At a TSI of 60, Moose Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. Moose Lake reaches 21 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 1,559 acres, Moose Lake is one of the larger lakes in Sawyer County, with partial shoreline records supporting multiple distinct use patterns. Within the 50 graded lakes of Sawyer County, Moose Lake sits at rank 46, near the bottom of the county list.

Moose Lake has no invasive species recorded in Wisconsin state databases as of 2025, though prevention practices still apply at all access points. The fishery includes walleye among the lake's 5 documented species — a notable draw for Wisconsin anglers. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
