Blue Lake vs Clear Lake
Water quality, depth, fish species, and recreation comparison.
Blue Lake and Clear Lake both received the same overall water quality grade of A (Excellent). Both are in Oneida County, Wisconsin.
Blue Lake and Clear Lake are both in Wisconsin — a same-state head-to-head where the comparison comes down to lake-specific differences in depth, watershed, and monitoring history rather than the broader state-level water-quality regime. The grades are close: Blue Lake (A) and Clear Lake (A) 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.
Blue Lake
Crystal clear, you can see 23 ft down.
Clear Lake
No clarity data.
Side-by-Side Metrics
| Metric | Blue Lake | Clear Lake |
|---|---|---|
| Overall Grade | A (Excellent) | A (Excellent) |
| Water Clarity | 23 ft | No data |
| Phosphorus | 10.5 µg/L | 10.8 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 49 ft | 95 ft |
| Surface Area | 441 acres | 873 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 4 | 6 |
| Trophic State | oligotrophic | oligotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade A. The tiebreakers come down to what you want from the lake. Blue Lake has fewer fish species than Clear Lake.
