Lake Marie vs Lake Paho

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

Lake Marie has a higher water quality grade (B, Good) than Lake Paho (D, Poor). Both are in Mercer County, Wisconsin.

Lake Marie and Lake Paho are both in Missouri — a same-state head-to-head where the comparison comes down to lake-specific differences in depth, watershed, and monitoring history rather than the broader state-level water-quality regime. Lake Marie (B) is materially cleaner than Lake Paho (D). A gap that wide is unlikely to close in a single year of remediation work; it reflects multi-decade differences in the lakes themselves.

For a recreational visitor, the wider grade gap is decisive — Lake Marie 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?

B

Lake Marie

Mercer County, Wisconsin

Moderate clarity, visible to about 7.8 ft.

D

Lake Paho
