Fall Lake vs White Iron Lake
Water quality, depth, fish species, and recreation comparison.
Fall Lake and White Iron Lake read the same on nutrients and algae. Both are in Lake County, Minnesota.
Fall Lake and White Iron 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 sit close on the readings, Fall Lake versus White Iron Lake. The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
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.
Fall Lake
Murky, only visible to about 5.5 ft.
White Iron Lake
Murky, only visible to about 4.5 ft.
Side-by-Side Metrics
| Metric | Fall Lake | White Iron Lake |
|---|---|---|
| Water Clarity | 5.5 ft Better | 4.5 ft |
| Phosphorus | 21 µg/L | 20 µg/L Better |
| Chlorophyll-a (Algae) | 6 µg/L | 3.7 µg/L Better |
| Maximum Depth | 32 ft | 47 ft Better |
| Surface Area | 2,258 acres | 3,237 acres |
| Public Access | Yes | Yes |
| Fish Species | 12 Better | 10 |
| Trophic State | mesotrophic | mesotrophic |
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 A. The tiebreakers come down to clarity (Fall Lake: 5.5 ft, White Iron Lake: 4.5 ft) and what you want from the lake. Fall Lake supports more documented fish species.
