Cadotte Lake
Burnett County, WisconsinLimited DataMesotrophic
Cadotte Lake sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year.
Mesotrophic conditions dominate at Cadotte Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. A maximum depth of 21 ft puts Cadotte Lake in the middle of Wisconsin's depth distribution. Cadotte Lake covers 121 acres alongside partial shoreline records — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Within Burnett County's 57 graded lakes, Cadotte Lake ranks 41 — below the local median, though not at the bottom.
No invasive species are currently listed at Cadotte Lake — the lake remains off the Wisconsin infested-waters roster. The fishery is bass-led, with 4 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.
