Big Sand Lake vs Lower Bottle Lake
Water quality, depth, fish species, and recreation comparison.
Big Sand Lake and Lower Bottle Lake both received the same overall water quality grade of A (Excellent). Both are in Hubbard County, Minnesota.
Big Sand Lake and Lower Bottle 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: Big Sand Lake (A) and Lower Bottle 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 | Big Sand Lake | Lower Bottle Lake |
|---|---|---|
| Overall Grade | A (Excellent) | A (Excellent) |
| Water Clarity | 23 ft | 15 ft |
| Phosphorus | 7 µg/L | 10 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 135 ft | 110 ft |
| Surface Area | 1.6K acres | 641.17 acres |
| Public Access | Yes | No |
| Fish Species | 1 | 1 |
| Trophic State | oligotrophic | oligotrophic |
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 (Big Sand Lake: 23 ft, Lower Bottle Lake: 15 ft) and what you want from the lake. Big Sand Lake matches its peer on species count.
