Beaver Dam Lake vs Fox Lake

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

Beaver Dam Lake and Fox Lake both received the same overall water quality grade of F (Very Poor). Both are in Dodge County, Wisconsin.

Beaver Dam Lake and Fox Lake are both in Wisconsin — 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: Beaver Dam Lake (F) and Fox Lake (F) 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.

Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).

Verdict

Both lakes earn the same Grade F. The tiebreakers come down to clarity (Beaver Dam Lake: 1 ft, Fox Lake: 1.7 ft) and what you want from the lake. Beaver Dam Lake matches its peer on species count.
