Lake Lamoure vs Sprague Lake
Water quality, depth, fish species, and recreation comparison.
Lake Lamoure has a higher water quality grade (C, Fair) than Sprague Lake (F, Very Poor). Both are in Wisconsin.
Both Lake Lamoure and Sprague 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 meaningfully apart: Lake Lamoure grades a C while Sprague Lake 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 — Lake Lamoure 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?
Lake Lamoure
Moderate clarity, visible to about 8 ft.
Sprague Lake
Very murky, less than 1.6 ft of visibility.
Side-by-Side Metrics
| Metric | Lake Lamoure | Sprague Lake |
|---|---|---|
| Overall Grade | C (Fair) | F (Very Poor) |
| Water Clarity | 8 ft | 1.6 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | 18.4 µg/L | 43.4 µg/L |
| Maximum Depth | - | - |
| Surface Area | 494.1 acres | 58 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
Lake Lamoure wins on overall water quality with a Grade C versus Sprague Lake's Grade F. Water clarity: 8 ft vs 1.6 ft. For fishing diversity, Lake Lamoure also leads with 0 species.
