Dutch Hollow Lake vs Lake Redstone
Water quality, depth, fish species, and recreation comparison.
Dutch Hollow Lake has a higher water quality grade (A, Excellent) than Lake Redstone (F, Very Poor). Both are in Sauk County, Wisconsin.
Both Dutch Hollow Lake and Lake Redstone sit in Wisconsin. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. The grades are meaningfully apart: Dutch Hollow Lake grades a A while Lake Redstone grades a F. That two-letter spread reflects real underlying differences — different watershed inputs, different depth profiles, or different monitoring rigor.
For a recreational visitor, the wider grade gap is decisive — Dutch Hollow Lake 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?

Side-by-Side Metrics
| Metric | Dutch Hollow Lake | Lake Redstone |
|---|---|---|
| Overall Grade | A (Excellent) | F (Very Poor) |
| Water Clarity | 15 ft | 2 ft |
| Phosphorus | 13.1 µg/L | 92 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | - |
| Surface Area | 125 acres | 612 acres |
| Public Access | Unknown | Unknown |

Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Dutch Hollow Lake wins on overall water quality with a Grade A versus Lake Redstone's Grade F. Water clarity: 15 ft vs 2 ft. For fishing diversity, Dutch Hollow Lake also leads with 0 species.
