Callaway Fork Lake vs Lake 36

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

Callaway Fork Lake has a higher water quality grade (D, Poor) than Lake 36 (D, Poor). Both are in St. Charles County, Wisconsin.

Both Callaway Fork Lake and Lake 36 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 — Callaway Fork Lake (D) versus Lake 36 (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.
