Forest Lake vs Hazel Creek Lk. Lake

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

Forest Lake has a higher water quality grade (B, Good) than Hazel Creek Lk. Lake (C, Fair). Both are in Adair County, Wisconsin.

Forest Lake and Hazel Creek Lk. Lake are both in Missouri — 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: Forest Lake (B) and Hazel Creek Lk. Lake (C) 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.
