Lake Carmel vs Seven Hills Lake
Water quality, depth, fish species, and recreation comparison.
Lake Carmel and Seven Hills Lake both received the same overall water quality grade of D (Poor). Both are in Putnam County, Wisconsin.
Lake Carmel and Seven Hills Lake are both in New York — 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: Lake Carmel (D) and Seven Hills 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.

Side-by-Side Metrics
| Metric | Lake Carmel | Seven Hills Lake |
|---|---|---|

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 (Lake Carmel: 5.6 ft, Seven Hills Lake: 4.8 ft) and what you want from the lake. Lake Carmel matches its peer on species count.
