Ml-Peterson Lake vs Ml-Se Lake
Water quality, depth, fish species, and recreation comparison.
Ml-Peterson Lake has a higher water quality grade (B, Good) than Ml-Se Lake (B, Good). Both are in Mille Lacs County, Minnesota.
Ml-Peterson Lake and Ml-Se 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: Ml-Peterson Lake (B) and Ml-Se Lake (B) 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 | Ml-Peterson Lake | Ml-Se Lake |
|---|---|---|
| Overall Grade | B (Good) | B (Good) |
| Water Clarity | 7.4 ft | 7.4 ft |
| Phosphorus | 26.5 µg/L | 26.5 µg/L |
| Chlorophyll-a (Algae) | 3.9 µg/L | 5.6 µg/L |
| Maximum Depth | 42 ft | 42 ft |
| Surface Area | 128.3K acres | 128.3K acres |
| Public Access | Yes | Yes |
| Fish Species | 1 | 1 |
| Trophic State | mesotrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Ml-Peterson Lake wins on overall water quality with a Grade B versus Ml-Se Lake's Grade B. Water clarity: 7.4 ft vs 7.4 ft. For fishing diversity, Ml-Peterson Lake also leads with 1 species.
