Deer Lake vs Oquaga Lake
Water quality, depth, fish species, and recreation comparison.
Oquaga Lake has a higher water quality grade (A, Excellent) than Deer Lake (D, Poor). Both are in Broome County, Wisconsin.
Both Deer Lake and Oquaga Lake sit in New York. 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. Oquaga Lake (A) is materially cleaner than Deer Lake (D). 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 — Oquaga 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?

Side-by-Side Metrics
| Metric | Deer Lake | Oquaga Lake |
|---|---|---|
| Overall Grade | D (Poor) | A (Excellent) |
| Water Clarity | 4.6 ft | 26.2 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | - |
| Surface Area | 32 acres | 134 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | eutrophic | oligotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Oquaga Lake wins on overall water quality with a Grade A versus Deer Lake's Grade D. Water clarity: 26.2 ft vs 4.6 ft. For fishing diversity, Oquaga Lake also leads with 0 species.
