Lake Beulah vs Lake Beulah

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

Lake Beulah and Lake Beulah both received the same overall water quality grade of A (Excellent). Both are in Walworth County, Wisconsin.

Both Lake Beulah and Lake Beulah sit in Wisconsin. 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: Lake Beulah (A) and Lake Beulah (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.

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

Verdict

Both lakes earn the same Grade A. The tiebreakers come down to clarity (Lake Beulah: 11 ft, Lake Beulah: 10 ft) and what you want from the lake. Lake Beulah matches its peer on species count.
