Jo Shelby Lake vs Marceline City Lake New Nr. Dam

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

Jo Shelby Lake has a higher water quality grade (C, Fair) than Marceline City Lake New Nr. Dam (C, Fair). Both are in Wisconsin.

Both Jo Shelby Lake and Marceline City Lake New Nr. Dam sit in Missouri. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. These two are within a letter of each other on the rubric — Jo Shelby Lake (C) versus Marceline City Lake New Nr. Dam (C). The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.

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.
