Beltrami Lake vs Stump Lake
Water quality, depth, fish species, and recreation comparison.
Beltrami Lake and Stump Lake both received the same overall water quality grade of A (Excellent). Both are in Beltrami County, Minnesota.
Beltrami Lake and Stump 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: Beltrami Lake (A) and Stump 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.

Side-by-Side Metrics
| Metric | Beltrami Lake | Stump Lake |
|---|---|---|
| Overall Grade | A (Excellent) | A (Excellent) |

| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | - |
| Surface Area | 853 acres | 201 acres |
| Public Access | Unknown | Unknown |

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 (Beltrami Lake: 11 ft, Stump Lake: 12.5 ft) and what you want from the lake. Beltrami Lake matches its peer on species count.
