Altoona Lake vs Hallie Lake

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

Hallie Lake has a higher water quality grade (D, Poor) than Altoona Lake (F, Very Poor). Both are in Wisconsin.

Altoona Lake and Hallie 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: Altoona Lake (F) and Hallie 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.
