Lake 36 vs Lake 37

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

Lake 37 has a higher water quality grade (B, Good) than Lake 36 (D, Poor). Both are in St. Charles County, Wisconsin.

Both Lake 36 and Lake 37 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. The grades are meaningfully apart: Lake 37 grades a B while Lake 36 grades a D. That two-letter spread reflects real underlying differences — different watershed inputs, different depth profiles, or different monitoring rigor.

For a recreational visitor, the wider grade gap is decisive — Lake 37 is the better water-quality choice. For a researcher, the gap is the interesting part: what is different about the two watersheds, and which of those differences is mutable?

D

Lake 36

St. Charles County, Wisconsin

Very murky, less than 2.5 ft of visibility.

B
