Fawn Lake vs Sherwood Lake Nr. Dam

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

Sherwood Lake Nr. Dam has a higher water quality grade (B, Good) than Fawn Lake (C, Fair). Both are in Wisconsin.

Fawn Lake and Sherwood Lake Nr. Dam 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: Fawn Lake (C) and Sherwood Lake Nr. Dam (B) 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.
