Calhoun Lake vs Green Lake
Water quality, depth, fish species, and recreation comparison.
Green Lake has a higher water quality grade (A, Excellent) than Calhoun Lake (B, Good). Both are in Kandiyohi County, Minnesota.
Calhoun Lake and Green Lake 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. These two are within a letter of each other on the rubric — Calhoun Lake (B) versus Green Lake (A). The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
With grades this close, the choice between the two lakes turns on non-water-quality factors: depth, fish species, public access, distance from home. The per-lake pages below cover all of those.
Calhoun Lake
Moderate clarity, visible to about 6.9 ft.

Side-by-Side Metrics
| Metric | Calhoun Lake | Green Lake |
|---|---|---|
| Overall Grade | B (Good) | A (Excellent) |
| Water Clarity | 6.9 ft | 14.1 ft |
| Phosphorus | 24 µg/L | 14 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 13 ft | 110 ft |
| Surface Area | 647 acres | 5,569 acres |
| Public Access | Yes | Yes |
| Fish Species | 15 | 22 |
| Trophic State | mesotrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Green Lake wins on overall water quality with a Grade A versus Calhoun Lake's Grade B. Water clarity: 14.1 ft vs 6.9 ft. For fishing diversity, Green Lake also leads with 22 species.
