Arrowhead Lake vs Moorehead Lake
Water quality, depth, fish species, and recreation comparison.
Arrowhead Lake has a higher water quality grade (C, Fair) than Moorehead Lake (D, Poor). Both are in Wisconsin.
Arrowhead Lake and Moorehead Lake are both in Iowa — 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: Arrowhead Lake (C) and Moorehead Lake (D) 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.

Side-by-Side Metrics
| Metric | Arrowhead Lake | Moorehead Lake |
|---|---|---|
| Overall Grade | C (Fair) | D (Poor) |
| Water Clarity | 5.6 ft | 3.7 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | 7.1 µg/L | 20.7 µg/L |
| Maximum Depth | - | - |
| Surface Area | 110 acres | 10.9 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
Arrowhead Lake wins on overall water quality with a Grade C versus Moorehead Lake's Grade D. Water clarity: 5.6 ft vs 3.7 ft. For fishing diversity, Arrowhead Lake also leads with 0 species.
