Lake Delton vs Lake Redstone
Water quality, depth, fish species, and recreation comparison.
Lake Delton and Lake Redstone both received the same overall water quality grade of F (Very Poor). Both are in Sauk County, Wisconsin.
Lake Delton and Lake Redstone 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. The grades are close: Lake Delton (F) and Lake Redstone (F) are within one letter of each other on the LakeGrade rubric. The per-parameter sub-grades below will show where the small differences actually live.
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 Delton
Very murky, less than 2.5 ft of visibility.
Lake Redstone
Very murky, less than 2 ft of visibility.
Side-by-Side Metrics
| Metric | Lake Delton | Lake Redstone |
|---|---|---|
| Overall Grade | F (Very Poor) | F (Very Poor) |
| Water Clarity | 2.5 ft | 2 ft |
| Phosphorus | No data | 92 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | - |
| Surface Area | 267 acres | 612 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 F. The tiebreakers come down to clarity (Lake Delton: 2.5 ft, Lake Redstone: 2 ft) and what you want from the lake. Lake Delton matches its peer on species count.
