Arroda Lake vs Harmony Lake
Water quality, depth, fish species, and recreation comparison.
Arroda Lake has a higher water quality grade (B, Good) than Harmony Lake (C, Fair). Both are in Wisconsin.
Both Arroda Lake and Harmony Lake sit in North Dakota. 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 close: Arroda Lake (B) and Harmony Lake (C) 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.
Arroda Lake
Moderate clarity, visible to about 6.7 ft.
Harmony Lake

Side-by-Side Metrics
| Metric | Arroda Lake | Harmony Lake |
