Geneva Lake vs Le Homme Dieu Lake
Water quality, depth, fish species, and recreation comparison.
Geneva Lake and Le Homme Dieu Lake read the same on nutrients and algae. Both are in Douglas County, Minnesota.
Both Geneva Lake and Le Homme Dieu 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. The readings are close: Geneva Lake and Le Homme Dieu 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.
Geneva Lake
Good clarity, visible to about 14.1 ft.
Le Homme Dieu Lake
Good clarity, visible to about 13.1 ft.
Side-by-Side Metrics
| Metric | Geneva Lake | Le Homme Dieu Lake |
|---|---|---|
| Water Clarity | 14.1 ft Better | 13.1 ft |
| Phosphorus | 21.5 µg/L | 21 µg/L Better |
| Chlorophyll-a (Algae) | 4.9 µg/L | 3.7 µg/L Better |
| Maximum Depth | 63 ft | 85 ft Better |
| Surface Area | 640 acres | 1,801 acres |
| Public Access | Yes | Yes |
| Fish Species | 17 | 20 Better |
| 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 (Geneva Lake: 14.1 ft, Le Homme Dieu Lake: 13.1 ft) and what you want from the lake. Geneva Lake has fewer fish species than Le Homme Dieu Lake.
