Brantingham Lake vs Lake Bonaparte

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

Lake Bonaparte has a higher water quality grade (A, Excellent) than Brantingham Lake (B, Good). Both are in Lewis County, Wisconsin.

Both Brantingham Lake and Lake Bonaparte 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. The grades are close: Brantingham Lake (B) and Lake Bonaparte (A) 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.
