Lake 36 vs Lake St. Louis
Water quality, depth, fish species, and recreation comparison.
Lake 36 has a higher water quality grade (D, Poor) than Lake St. Louis (D, Poor). Both are in St. Charles County, Wisconsin.
Both Lake 36 and Lake St. Louis sit in Missouri. 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: Lake 36 (D) and Lake St. Louis (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.
Lake 36
Very murky, less than 2.5 ft of visibility.

Side-by-Side Metrics
| Metric | Lake 36 | Lake St. Louis |
|---|---|---|
| Overall Grade | D (Poor) | D (Poor) |
| Water Clarity | 2.5 ft | 2.7 ft |
| Phosphorus | 31 µg/L | 50 µg/L |
| Chlorophyll-a (Algae) | 29.4 µg/L | 74.3 µg/L |
| Maximum Depth | - | - |
| Surface Area | 16 acres | 563 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | eutrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Lake 36 wins on overall water quality with a Grade D versus Lake St. Louis's Grade D. Water clarity: 2.5 ft vs 2.7 ft. For fishing diversity, Lake 36 also leads with 0 species.
