Lake 36 vs Lake 37
Water quality, depth, fish species, and recreation comparison.
Lake 37 has a higher water quality grade (B, Good) than Lake 36 (D, Poor). Both are in St. Charles County, Wisconsin.
Both Lake 36 and Lake 37 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 meaningfully apart: Lake 37 grades a B while Lake 36 grades a D. That two-letter spread reflects real underlying differences — different watershed inputs, different depth profiles, or different monitoring rigor.
For a recreational visitor, the wider grade gap is decisive — Lake 37 is the better water-quality choice. For a researcher, the gap is the interesting part: what is different about the two watersheds, and which of those differences is mutable?
Lake 36
Very murky, less than 2.5 ft of visibility.
Lake 37
Murky, only visible to about 4 ft.
Side-by-Side Metrics
| Metric | Lake 36 | Lake 37 |
|---|---|---|
| Overall Grade | D (Poor) | B (Good) |
| Water Clarity | 2.5 ft | 4 ft |
| Phosphorus | 31 µg/L | 16 µg/L |
| Chlorophyll-a (Algae) | 29.4 µg/L | 7.2 µg/L |
| Maximum Depth | - | - |
| Surface Area | 16 acres | 30 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 37 wins on overall water quality with a Grade B versus Lake 36's Grade D. Water clarity: 4 ft vs 2.5 ft. For fishing diversity, Lake 37 also leads with 0 species.
