Crow R Mill Pond vs Lake Monongalia
Water quality, depth, fish species, and recreation comparison.
Crow R Mill Pond has a higher water quality grade (C, Fair) than Lake Monongalia (F, Very Poor). Both are in Kandiyohi County, Minnesota.
Crow R Mill Pond and Lake Monongalia are both in Minnesota — 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. Crow R Mill Pond (C) 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 R 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 R Mill Pond

Side-by-Side Metrics
| Metric | Crow R Mill Pond | Lake Monongalia |
|---|---|---|
| Overall Grade | C (Fair) | F (Very Poor) |
| Water Clarity | 6 ft | 3.3 ft |
| Phosphorus | 24 µg/L | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 14 ft | 14 ft |
| Surface Area | 2.3K acres | 2.3K acres |
| Public Access | Yes | Yes |
