Bass Lake
Burnett County, WisconsinLimited DataOligotrophic
On the LakeGrade scale Bass Lake grades a B, with clarity at 14.8 ft and phosphorus readings still being added placing it above the Wisconsin median. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.
Trophically, Bass Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. A maximum depth of 45 ft puts Bass Lake in the middle of Wisconsin's depth distribution. The lake is compact at 53 acres, with partial shoreline records and little volume to buffer nutrient inputs. Bass Lake ranks 58 of 70 in Burnett County — at the lower end of the locally monitored distribution.
Bass Lake has no invasive species recorded in Wisconsin state databases as of 2024, though prevention practices still apply at all access points. The fishery is bass-led, with 3 documented species across the lake's records. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
