Sherwood Lake Nr. Dam vs Sherwood Lake

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

Sherwood Lake Nr. Dam and Sherwood Lake both received the same overall water quality grade of B (Good). Both are in Warren County, Wisconsin.

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

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

Verdict

Both lakes earn the same Grade B. The tiebreakers come down to clarity (Sherwood Lake Nr. Dam: 5.9 ft, Sherwood Lake: 4.9 ft) and what you want from the lake. Sherwood Lake Nr. Dam matches its peer on species count.
