Andrusia Lake vs Little Big Lake
Water quality, depth, fish species, and recreation comparison.
Andrusia Lake has a higher water quality grade (A, Excellent) than Little Big Lake (B, Good). Both are in Beltrami County, Minnesota.
Andrusia Lake and Little Big 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: Andrusia Lake (A) and Little Big 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 | Andrusia Lake | Little Big Lake |
|---|---|---|
| Overall Grade | A (Excellent) | B (Good) |
| Water Clarity | 15.5 ft | 9.3 ft |

| Chlorophyll-a (Algae) | No data | 2.8 µg/L |
| Maximum Depth | 60 ft | 35 ft |
| Surface Area | 1.6K acres | 3.6K 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).
