Barber Lake
Sawyer County, WisconsinOligotrophic
On the LakeGrade rubric, Barber Lake pulls an A: clarity at 33.9 ft and 14 µg/L of phosphorus put it in the top bracket for Wisconsin. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.
Trophically, Barber Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. A maximum depth of 21 ft puts Barber Lake in the middle of Wisconsin's depth distribution. Barber Lake covers 138 acres alongside partial shoreline records — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Barber Lake ranks 25 of 52 in Sawyer County — solidly in the upper half of the local distribution.
Barber Lake carries an invasive watermilfoil record — boat-launch decontamination and shoreline care matter more here than at uninfested lakes. The fishery includes walleye alongside the lake's other 5 documented species — a notable draw for Wisconsin anglers. Public access is available — the lake is on the Wisconsin DNR public-access list. 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.
