Lake Beulah vs Whitewater Lake
Water quality, depth, fish species, and recreation comparison.
Lake Beulah has a higher water quality grade (A, Excellent) than Whitewater Lake (B, Good). Both are in Walworth County, Wisconsin.
Lake Beulah and Whitewater Lake 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. These two are within a letter of each other on the rubric — Lake Beulah (A) versus Whitewater Lake (B). The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
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 Beulah
Good clarity, visible to about 10 ft.
Whitewater Lake
Murky, only visible to about 4 ft.
Side-by-Side Metrics
| Metric | Lake Beulah | Whitewater Lake |
|---|---|---|
| Overall Grade | A (Excellent) | B (Good) |
| Water Clarity | 10 ft | 4 ft |
| Phosphorus | 13.4 µg/L | 26.2 µg/L |
| Chlorophyll-a (Algae) | 2.5 µg/L | No data |
| Maximum Depth | 58 ft | 35 ft |
| Surface Area | 812 acres | 625 acres |
| Public Access | Yes | Yes |
| Fish Species | 3 | 4 |
| 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 Whitewater Lake's Grade B. Water clarity: 10 ft vs 4 ft. For more fish-species variety, Whitewater Lake edges ahead with 4 documented species.
