Eagle Lake vs Long Lake
Water quality, depth, fish species, and recreation comparison.
Eagle Lake has a higher water quality grade (C, Fair) than Long Lake (D, Poor). Both are in Kandiyohi County, Minnesota.
Eagle Lake and Long 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 — Eagle Lake (C) versus Long Lake (D). 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.
Eagle Lake
Murky, only visible to about 6.4 ft.
Long Lake
Very murky, less than 3 ft of visibility.
Side-by-Side Metrics
| Metric | Eagle Lake | Long Lake |
|---|---|---|
| Overall Grade | C (Fair) | D (Poor) |
| Water Clarity | 6.4 ft | 3 ft |
| Phosphorus | 23 µg/L | 88 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 67 ft | 16 ft |
| Surface Area | 849.47 acres | 1.6K acres |
| Public Access | Yes | Yes |
| Fish Species | 1 | 1 |
| Trophic State | mesotrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Eagle Lake wins on overall water quality with a Grade C versus Long Lake's Grade D. Water clarity: 6.4 ft vs 3 ft. For fishing diversity, Eagle Lake also leads with 1 species.
