Castlenovo Lake vs Red Fox Lake

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

Castlenovo Lake has a higher water quality grade (B, Good) than Red Fox Lake (C, Fair). Both are in Warren County, Wisconsin.

Castlenovo Lake and Red Fox 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: Castlenovo Lake (B) and Red Fox 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.

Castlenovo Lake

Warren County, Wisconsin
