Crow River Mill Pond vs Lake Monongalia
Water quality, depth, fish species, and recreation comparison.
Crow River Mill Pond has a higher water quality grade (B, Good) than Lake Monongalia (F, Very Poor). Both are in Kandiyohi County, Minnesota.
Both Crow River Mill Pond and Lake Monongalia sit in Minnesota. 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. Crow River Mill Pond (B) is materially cleaner than Lake Monongalia (F). 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 — Crow River Mill Pond 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?
Crow River Mill Pond
Good clarity, visible to about 10.2 ft.
Lake Monongalia
