Eagle Lake vs Fremont Lake
Water quality, depth, fish species, and recreation comparison.
Eagle Lake and Fremont Lake read the same on nutrients and algae. Both are in Sherburne County, Minnesota.
Eagle Lake and Fremont 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. The readings are close: Eagle Lake and Fremont Lake sit within a narrow band of each other on phosphorus, chlorophyll-a and clarity. The per-parameter table below shows where the small differences actually live.
With readings 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
Very murky, less than 3 ft of visibility.
Fremont Lake
Very murky, less than 3 ft of visibility.
Side-by-Side Metrics
| Metric | Eagle Lake | Fremont Lake |
|---|---|---|
| Water Clarity | 3 ft | 3 ft |
| Phosphorus | 61.5 µg/L | 40 µg/L Better |
| Chlorophyll-a (Algae) | 29.5 µg/L | 17.3 µg/L Better |
| Maximum Depth | 18 ft Better | 8 ft |
| Surface Area | 462 acres | 493 acres |
| Public Access | Yes | Yes |
| Fish Species | 15 Better | 0 |
| Trophic State | eutrophic | eutrophic |
A green ✓ marks the better value for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better). Surface area and trophic state carry no tick — a bigger lake is not a better lake.
Verdict
Both lakes earn the same Grade D. The tiebreakers come down to clarity (Eagle Lake: 3 ft, Fremont Lake: 3 ft) and what you want from the lake. Eagle Lake supports more documented fish species.
