Jamestown Reservoir vs Jamestown Reservoir
Water quality, depth, fish species, and recreation comparison.
Jamestown Reservoir has a higher water quality grade (B, Good) than Jamestown Reservoir (D, Poor). Both are in Stutsman County, Wisconsin.
Jamestown Reservoir and Jamestown Reservoir 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. The grades are meaningfully apart: Jamestown Reservoir grades a B while Jamestown Reservoir grades a D. 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 — Jamestown Reservoir 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 | Jamestown Reservoir | Jamestown Reservoir |
|---|---|---|
| Overall Grade | D (Poor) | B (Good) |
| Water Clarity | 6 ft | 7.2 ft |
| Phosphorus | 560.5 µg/L | No data |
| Chlorophyll-a (Algae) | 17.6 µg/L | 8.5 µg/L |
| Maximum Depth | - | - |
| Surface Area | 17.4K acres | 17.4K 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
Jamestown Reservoir wins on overall water quality with a Grade B versus Jamestown Reservoir's Grade D. Water clarity: 7.2 ft vs 6 ft. For fishing diversity, Jamestown Reservoir also leads with 0 species.
