Old Reservoir vs Sugar Creek Lake
Water quality, depth, fish species, and recreation comparison.
Old Reservoir has a higher water quality grade (C, Fair) than Sugar Creek Lake (D, Poor). Both are in Randolph County, Wisconsin.
Both Old Reservoir and Sugar Creek Lake sit in Missouri. 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. These two are within a letter of each other on the rubric — Old Reservoir (C) versus Sugar Creek Lake (D). The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
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.
Old Reservoir
Murky, only visible to about 3.6 ft.
Sugar Creek Lake

Side-by-Side Metrics
| Metric | Old Reservoir | Sugar Creek Lake |
|---|---|---|
| Overall Grade | C (Fair) | D (Poor) |
| Water Clarity | 3.6 ft | 2.5 ft |
| Phosphorus | 33 µg/L | 50.5 µg/L |
| Chlorophyll-a (Algae) | 14.2 µg/L | 19.3 µg/L |
| Maximum Depth | - | - |
| Surface Area | 21 acres | 323 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).
