Mark Twain Lake vs Perry City Lake
Water quality, depth, fish species, and recreation comparison.
Mark Twain Lake has a higher water quality grade (D, Poor) than Perry City Lake (F, Very Poor). Both are in Ralls County, Wisconsin.
Both Mark Twain Lake and Perry City Lake 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 — Mark Twain Lake (D) versus Perry City Lake (F). 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.
