Pepin Lake vs Pepin Lake
Water quality, depth, fish species, and recreation comparison.
Pepin Lake and Pepin Lake both received the same overall water quality grade of F (Very Poor).
Pepin Lake is in Minnesota; Pepin Lake is in Wisconsin. Cross-state comparisons carry an extra wrinkle — Minnesota PCA and Wisconsin DNR use slightly different sampling cadences and station coverage, though both feed the same EPA Water Quality Portal. The grades are close: Pepin Lake (F) and Pepin Lake (F) 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.
Pepin Lake
Very murky, less than 3 ft of visibility.
Pepin Lake
Very murky, less than 1.6 ft of visibility.
Side-by-Side Metrics
| Metric | Pepin Lake | Pepin Lake |
|---|---|---|
| Overall Grade | F (Very Poor) | F (Very Poor) |
| Water Clarity | 3 ft | 1.6 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 60 ft | 60 ft |
| Surface Area | 12.3K acres | 24.6K acres |
| Public Access | Yes | Unknown |
| Fish Species | 1 | 0 |
| Trophic State | eutrophic | hypereutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade F. The tiebreakers come down to clarity (Pepin Lake: 3 ft, Pepin Lake: 1.6 ft) and what you want from the lake. Pepin Lake supports more documented fish species.
