Cranberry Lake vs Maple Lake
Water quality, depth, fish species, and recreation comparison.
Maple Lake has a higher water quality grade (A, Excellent) than Cranberry Lake (C, Fair). Both are in Oneida County, Wisconsin.
Both Cranberry Lake and Maple Lake sit in Wisconsin. 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. Maple Lake (A) is materially cleaner than Cranberry Lake (C). 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 — Maple 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?
Cranberry Lake
Murky, only visible to about 4.5 ft.
Maple Lake

Side-by-Side Metrics
| Metric | Cranberry Lake | Maple Lake |
|---|---|---|
| Overall Grade | C (Fair) | A (Excellent) |
| Water Clarity | 4.5 ft | 12.5 ft |
| Phosphorus | 30.8 µg/L | 15.8 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | - |
| Surface Area | 18 acres | 144 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | eutrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Maple Lake wins on overall water quality with a Grade A versus Cranberry Lake's Grade C. Water clarity: 12.5 ft vs 4.5 ft. For fishing diversity, Maple Lake also leads with 0 species.
