Four Lake vs One Lake
Water quality, depth, fish species, and recreation comparison.
One Lake has a higher water quality grade (C, Fair) than Four Lake (D, Poor). Both are in Lake County, Minnesota.
Four Lake and One 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: Four Lake (D) and One Lake (C) 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.
Four Lake
Murky, only visible to about 6.4 ft.
One Lake
Moderate clarity, visible to about 7.5 ft.
Side-by-Side Metrics
| Metric | Four Lake | One Lake |
|---|---|---|
| Overall Grade | D (Poor) | C (Fair) |
| Water Clarity | 6.4 ft | 7.5 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 25 ft | 57 ft |
| Surface Area | 610.88 acres | 845.95 acres |
| Public Access | No | Yes |
| Fish Species | 1 | 1 |
| Trophic State | eutrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
One Lake wins on overall water quality with a Grade C versus Four Lake's Grade D. Water clarity: 7.5 ft vs 6.4 ft. For fishing diversity, One Lake also leads with 1 species.
