Ellis Lake vs Genegantslet Lake

Water quality, depth, fish species, and recreation comparison.

Genegantslet Lake has a higher water quality grade (B, Good) than Ellis Lake (C, Fair). Both are in Wisconsin.

Ellis Lake and Genegantslet 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: Ellis Lake (C) and Genegantslet Lake (B) 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.
