Charles Mill Reservoir vs Leesville Lake
Water quality, depth, fish species, and recreation comparison.
Leesville Lake has a higher water quality grade (D, Poor) than Charles Mill Reservoir (F, Very Poor). Both are in Wisconsin.
Both Charles Mill Reservoir and Leesville Lake sit in Ohio. 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 — Charles Mill Reservoir (F) versus Leesville Lake (D). 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.
