Castle Rock Dam Lake vs Sheep Creek Dam Lake
Water quality, depth, fish species, and recreation comparison.
Castle Rock Dam Lake and Sheep Creek Dam Lake both received the same overall water quality grade of D (Poor). Both are in Wisconsin.
Castle Rock Dam Lake and Sheep Creek 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. The grades are close: Castle Rock Dam Lake (D) and Sheep Creek Dam 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.
Castle Rock Dam Lake
Murky, only visible to about 3.8 ft.
Sheep Creek Dam Lake
Very murky, less than 2.7 ft of visibility.
Side-by-Side Metrics
| Metric | Castle Rock Dam Lake | Sheep Creek Dam Lake |
|---|---|---|
| Overall Grade | D (Poor) | D (Poor) |
| Water Clarity | 3.8 ft | 2.7 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | 24.3 µg/L | 15 µg/L |
| Maximum Depth | - | - |
| Surface Area | 14.2 acres | 87 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
Both lakes earn the same Grade D. The tiebreakers come down to clarity (Castle Rock Dam Lake: 3.8 ft, Sheep Creek Dam Lake: 2.7 ft) and what you want from the lake. Castle Rock Dam Lake matches its peer on species count.
