Deer Lake vs Moose Lake
Water quality, depth, fish species, and recreation comparison.
Deer Lake has a higher water quality grade (A, Excellent) than Moose Lake (B, Good). Both are in Itasca County, Minnesota.
Both Deer Lake and Moose Lake sit in Minnesota. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. The grades are close: Deer Lake (A) and Moose 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 | Deer Lake | Moose Lake |
|---|---|---|
| Overall Grade | A (Excellent) | B (Good) |
| Water Clarity | 13.1 ft | 11.5 ft |
| Phosphorus | 11 µg/L | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 121 ft | 61 ft |
| Surface Area | 4.1K acres | 1.3K acres |
| Public Access | Yes | Yes |
| Fish Species | 1 | 1 |
| Trophic State | oligotrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
