Arrowhead Lake vs Swan Lake Max Depth
Water quality, depth, fish species, and recreation comparison.
Arrowhead Lake has a higher water quality grade (C, Fair) than Swan Lake Max Depth (F, Very Poor). Both are in Wisconsin.
Both Arrowhead Lake and Swan Lake Max Depth sit in Iowa. 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: Arrowhead Lake grades a C while Swan Lake Max Depth 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 — Arrowhead 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?
Arrowhead Lake
Murky, only visible to about 5.6 ft.
Swan Lake Max Depth

Side-by-Side Metrics
| Metric | Arrowhead Lake | Swan Lake Max Depth |
|---|---|---|
| Overall Grade | C (Fair) | F (Very Poor) |
| Water Clarity | 5.6 ft | 1.4 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | 7.1 µg/L | 74 µg/L |
| Maximum Depth | - | - |
| Surface Area | 110 acres | 130 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | eutrophic | hypereutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Arrowhead Lake wins on overall water quality with a Grade C versus Swan Lake Max Depth's Grade F. Water clarity: 5.6 ft vs 1.4 ft. For fishing diversity, Arrowhead Lake also leads with 0 species.
