Arnegard Dam Lake vs Odland Dam Lake
Water quality, depth, fish species, and recreation comparison.
Arnegard Dam Lake has a higher water quality grade (A, Excellent) than Odland Dam Lake (D, Poor). Both are in Wisconsin.
Arnegard Dam Lake and Odland Dam Lake are both in North Dakota — 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. Arnegard Dam Lake (A) is materially cleaner than Odland Dam Lake (D). A gap that wide is unlikely to close in a single year of remediation work; it reflects multi-decade differences in the lakes themselves.
For a recreational visitor, the wider grade gap is decisive — Arnegard Dam 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 | Arnegard Dam Lake | Odland Dam Lake |
|---|---|---|
| Overall Grade | A (Excellent) | D (Poor) |
| Water Clarity | No data | 1.5 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | 3.1 µg/L | 29.6 µg/L |
| Maximum Depth | - | - |
| Surface Area | 24.2 acres | 128.2 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | mesotrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Arnegard Dam Lake wins on overall water quality with a Grade A versus Odland Dam Lake's Grade D. For fishing diversity, Arnegard Dam Lake also leads with 0 species.
