Louise Lake vs Mary Lake
Water quality, depth, fish species, and recreation comparison.
Louise Lake and Mary Lake both received the same overall water quality grade of B (Good). Both are in Dickinson County, Wisconsin.
Both Louise Lake and Mary Lake sit in Michigan. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. The grades are close: Louise Lake (B) and Mary 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.
Louise Lake
Good clarity, visible to about 12.5 ft.
Mary Lake
Good clarity, visible to about 13.8 ft.
Side-by-Side Metrics
| Metric | Louise Lake | Mary Lake |
|---|---|---|
| Overall Grade | B (Good) | B (Good) |
| Water Clarity | 12.5 ft | 13.8 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | - |
| Surface Area | 230 acres | 230 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 1 | 1 |
| Trophic State | mesotrophic | oligotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade B. The tiebreakers come down to clarity (Louise Lake: 12.5 ft, Mary Lake: 13.8 ft) and what you want from the lake. Louise Lake matches its peer on species count.
