Lake Paho vs North Bethany City Reservoir

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

North Bethany City Reservoir has a higher water quality grade (B, Good) than Lake Paho (D, Poor). Both are in Wisconsin.

Lake Paho and North Bethany City Reservoir 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. The grades are meaningfully apart: North Bethany City Reservoir grades a B while Lake Paho 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 — North Bethany City Reservoir 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?
