Lake Chetac North Basin vs Lake Chetac
Water quality, depth, fish species, and recreation comparison.
Lake Chetac North Basin and Lake Chetac both received the same overall water quality grade of D (Poor). Both are in Sawyer County, Wisconsin.
Both Lake Chetac North Basin and Lake Chetac sit in Wisconsin. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. The grades are close: Lake Chetac North Basin (D) and Lake Chetac (D) are within one letter of each other on the LakeGrade rubric. The per-parameter sub-grades below will show where the small differences actually live.
With grades this close, the choice between the two lakes turns on non-water-quality factors: depth, fish species, public access, distance from home. The per-lake pages below cover all of those.

Side-by-Side Metrics
| Metric | Lake Chetac North Basin | Lake Chetac |
|---|---|---|
| Overall Grade | D (Poor) | D (Poor) |
| Water Clarity | No data | No data |
| Phosphorus | 56.3 µg/L | 64.6 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 26 ft | 26 ft |
| Surface Area | 2,400 acres | 2,400 acres |
| Public Access | Yes | Yes |
| Fish Species | 5 | 5 |
| Trophic State | eutrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade D. The tiebreakers come down to what you want from the lake. Lake Chetac North Basin matches its peer on species count.
