Black Hawk Lake vs Cruson Slough Lake
Water quality, depth, fish species, and recreation comparison.
Black Hawk Lake and Cruson Slough Lake both received the same overall water quality grade of B (Good). Both are in Wisconsin.
Black Hawk Lake and Cruson Slough 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 — Black Hawk Lake (B) versus Cruson Slough 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.
Black Hawk Lake
Murky, only visible to about 5 ft.
Cruson Slough Lake
Moderate clarity, visible to about 7.6 ft.
Side-by-Side Metrics
| Metric | Black Hawk Lake | Cruson Slough Lake |
|---|---|---|
| Overall Grade | B (Good) | B (Good) |
| Water Clarity | 5 ft | 7.6 ft |
| Phosphorus | 19.9 µg/L | 28.9 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | - |
| Surface Area | 220 acres | 80 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
Both lakes earn the same Grade B. The tiebreakers come down to clarity (Black Hawk Lake: 5 ft, Cruson Slough Lake: 7.6 ft) and what you want from the lake. Black Hawk Lake matches its peer on species count.
