Lake Beulah vs Lake Beulah
Water quality, depth, fish species, and recreation comparison.
Lake Beulah has a higher water quality grade (A, Excellent) than Lake Beulah (C, Fair). Both are in Walworth County, Wisconsin.
Lake Beulah and Lake Beulah are both in Wisconsin — 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. Lake Beulah (A) is materially cleaner than Lake Beulah (C). A gap that wide is unlikely to close in a single year of remediation work; it reflects multi-decade differences in the lakes themselves.
For a recreational visitor, the wider grade gap is decisive — Lake Beulah 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 Beulah
Good clarity, visible to about 10 ft.
Lake Beulah
Very murky, less than 2.6 ft of visibility.
Side-by-Side Metrics
| Metric | Lake Beulah | Lake Beulah |
|---|---|---|
| Overall Grade | A (Excellent) | C (Fair) |
| Water Clarity | 10 ft | 2.6 ft |
| Phosphorus | 13.4 µg/L | 18 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 58 ft | 58 ft |
| Surface Area | 812 acres | 812 acres |
| Public Access | Yes | Yes |
| Fish Species | 3 | 3 |
| Trophic State | mesotrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Lake Beulah wins on overall water quality with a Grade A versus Lake Beulah's Grade C. Water clarity: 10 ft vs 2.6 ft. For fishing diversity, Lake Beulah also leads with 3 species.
