Fall Lake vs Farm Lake
Water quality, depth, fish species, and recreation comparison.
Fall Lake and Farm Lake read the same on nutrients and algae. Both are in Lake County, Minnesota.
Both Fall Lake and Farm Lake sit in Minnesota. A same-state comparison strips out the state-level water-quality regime as a variable: any differences in the readings here are about the lakes themselves, not the agencies sampling them. These two sit close on the readings, Fall Lake versus Farm 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.
Farm Lake
Murky, only visible to about 5.5 ft.
Side-by-Side Metrics
| Metric | Fall Lake | Farm Lake |
|---|---|---|
| Water Clarity | 5.5 ft | 5.5 ft |
| Phosphorus | 21 µg/L | 15 µg/L Better |
| Chlorophyll-a (Algae) | 6 µg/L | 4.7 µg/L Better |
| Maximum Depth | 32 ft | 56 ft Better |
| Surface Area | 2,258 acres | 1,292 acres |
| Public Access | Yes | Yes |
| Fish Species | 12 | 12 |
| 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, Farm Lake: 5.5 ft) and what you want from the lake. Fall Lake matches its peer on species count.
