Long Lake vs Plantagenet Lake
Water quality, depth, fish species, and recreation comparison.
Long Lake and Plantagenet Lake read the same on nutrients and algae. Both are in Hubbard County, Minnesota.
Both Long Lake and Plantagenet 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, Long Lake versus Plantagenet 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.
Long Lake
Good clarity, visible to about 11.2 ft.
Plantagenet Lake
Moderate clarity, visible to about 7 ft.
Side-by-Side Metrics
| Metric | Long Lake | Plantagenet Lake |
|---|---|---|
| Water Clarity | 11.2 ft Better | 7 ft |
| Phosphorus | 10 µg/L Better | 20 µg/L |
| Chlorophyll-a (Algae) | 4.5 µg/L Better | 6.7 µg/L |
| Maximum Depth | 135 ft Better | 65 ft |
| Surface Area | 1,926 acres | 2,531 acres |
| Public Access | Yes | Yes |
| Fish Species | 14 | 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 (Long Lake: 11.2 ft, Plantagenet Lake: 7 ft) and what you want from the lake. Long Lake has fewer fish species than Plantagenet Lake.
