Namakan Lake vs Namakan Lake
Water quality, depth, fish species, and recreation comparison.
Namakan Lake has a higher water quality grade (B, Good) than Namakan Lake (D, Poor). Both are in St. Louis County, Minnesota.
Namakan Lake and Namakan 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 meaningfully apart: Namakan Lake grades a B while Namakan Lake grades a D. That two-letter spread reflects real underlying differences — different watershed inputs, different depth profiles, or different monitoring rigor.
For a recreational visitor, the wider grade gap is decisive — Namakan Lake is the better water-quality choice. For a researcher, the gap is the interesting part: what is different about the two watersheds, and which of those differences is mutable?

Side-by-Side Metrics
| Metric | Namakan Lake | Namakan Lake |
|---|---|---|
| Overall Grade | D (Poor) | B (Good) |
| Water Clarity | 4.1 ft | 11.5 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 150 ft | 150 ft |
| Surface Area | 24.1K acres | 24.1K acres |
| Public Access | No | No |
| Fish Species | 1 | 1 |
| Trophic State | eutrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Namakan Lake wins on overall water quality with a Grade B versus Namakan Lake's Grade D. Water clarity: 11.5 ft vs 4.1 ft. For fishing diversity, Namakan Lake also leads with 1 species.
