Gladstone Lake vs Hubert Lake
Water quality, depth, fish species, and recreation comparison.
Gladstone Lake and Hubert Lake read the same on nutrients and algae. Both are in Crow Wing County, Minnesota.
Both Gladstone Lake and Hubert 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: Gladstone Lake and Hubert 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.
Gladstone Lake
Good clarity, visible to about 10.5 ft.
Hubert Lake
Crystal clear, you can see 17.1 ft down.
Side-by-Side Metrics
| Metric | Gladstone Lake | Hubert Lake |
|---|---|---|
| Water Clarity | 10.5 ft | 17.1 ft Better |
| Phosphorus | 17 µg/L | 13 µg/L Better |
| Chlorophyll-a (Algae) | 4.8 µg/L | 2.1 µg/L Better |
| Maximum Depth | 36 ft | 83 ft Better |
| Surface Area | 437 acres | 1,301 acres |
| Public Access | Yes | Yes |
| Fish Species | 15 | 16 Better |
| Trophic State | mesotrophic | oligotrophic |
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.
