Clear Lake vs Ml-Nw Lake
Water quality, depth, fish species, and recreation comparison.
Clear Lake has a higher water quality grade (A, Excellent) than Ml-Nw Lake (B, Good). Both are in Aitkin County, Minnesota.
Clear Lake and Ml-Nw 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. These two are within a letter of each other on the rubric — Clear Lake (A) versus Ml-Nw Lake (B). The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
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 | Clear Lake | Ml-Nw Lake |

| Chlorophyll-a (Algae) | No data | 5.7 µg/L |
| Maximum Depth | 24 ft | 42 ft |
| Surface Area | 573.5 acres | 128.3K acres |
| Public Access | Yes | Yes |
