Barrett Lake vs Pomme de Terre Lake
Water quality, depth, fish species, and recreation comparison.
Barrett Lake and Pomme de Terre Lake both received the same overall water quality grade of D (Poor). Both are in Grant County, Minnesota.
Barrett Lake and Pomme de Terre 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: Barrett Lake (D) and Pomme de Terre Lake (D) 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 | Barrett Lake | Pomme de Terre Lake |
|---|---|---|
| Overall Grade | D (Poor) | D (Poor) |
| Water Clarity | 4 ft | 4 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | - |

Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade D. The tiebreakers come down to clarity (Barrett Lake: 4 ft, Pomme de Terre Lake: 4 ft) and what you want from the lake. Barrett Lake matches its peer on species count.
