Bay Lake vs Clearwater Lake
Water quality, depth, fish species, and recreation comparison.
Bay Lake and Clearwater Lake both received the same overall water quality grade of A (Excellent). Both are in Crow Wing County, Minnesota.
Bay Lake and Clearwater Lake are both in Minnesota — 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: Bay Lake (A) and Clearwater 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.
Bay Lake
Crystal clear, you can see 18.5 ft down.
Clearwater Lake
Good clarity, visible to about 13 ft.
Side-by-Side Metrics
| Metric | Bay Lake | Clearwater Lake |
|---|---|---|
| Overall Grade | A (Excellent) | A (Excellent) |
| Water Clarity | 18.5 ft | 13 ft |
| Phosphorus | 11 µg/L | 12 µg/L |
| Chlorophyll-a (Algae) | 1.6 µg/L | 3.7 µg/L |
| Maximum Depth | 74 ft | 54 ft |
| Surface Area | 2,330 acres | 905 acres |
| Public Access | Yes | Yes |
| Fish Species | 13 | 16 |
| Trophic State | oligotrophic | mesotrophic |
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 clarity (Bay Lake: 18.5 ft, Clearwater Lake: 13 ft) and what you want from the lake. Bay Lake has fewer fish species than Clearwater Lake.
