Lake Kegonsa vs Lake Waubesa
Water quality, depth, fish species, and recreation comparison.
Lake Kegonsa has a higher water quality grade (C, Fair) than Lake Waubesa (D, Poor). Both are in Dane County, Wisconsin.
Lake Kegonsa and Lake Waubesa 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 Kegonsa (C) versus Lake Waubesa (D). 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 Kegonsa
Murky, only visible to about 3.7 ft.
Lake Waubesa

Side-by-Side Metrics
| Metric | Lake Kegonsa | Lake Waubesa |
|---|---|---|
| Overall Grade | C (Fair) | D (Poor) |
| Water Clarity | 3.7 ft | 3.2 ft |
| Phosphorus | 59.5 µg/L | 36.6 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | - |
| Surface Area | 2.7K acres | 5.4K acres |
| Public Access | Unknown | Unknown |

Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Lake Kegonsa wins on overall water quality with a Grade C versus Lake Waubesa's Grade D. Water clarity: 3.7 ft vs 3.2 ft. For fishing diversity, Lake Kegonsa also leads with 0 species.
