Fish Hook Lake vs Long Lake
Water quality, depth, fish species, and recreation comparison.
Fish Hook Lake and Long Lake read the same on nutrients and algae. Both are in Hubbard County, Minnesota.
Fish Hook Lake and Long 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. The readings are close: Fish Hook Lake and Long 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.
Fish Hook Lake
Good clarity, visible to about 10.2 ft.
Long Lake
Good clarity, visible to about 11.2 ft.
Side-by-Side Metrics
| Metric | Fish Hook Lake | Long Lake |
|---|---|---|
| Water Clarity | 10.2 ft | 11.2 ft Better |
| Phosphorus | 13 µg/L | 10 µg/L Better |
| Chlorophyll-a (Algae) | 4.5 µg/L | 4.5 µg/L |
| Maximum Depth | 76 ft | 135 ft Better |
| Surface Area | 1,643 acres | 1,926 acres |
| Public Access | Yes | Yes |
| Fish Species | 14 | 14 |
| 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 (Fish Hook Lake: 10.2 ft, Long Lake: 11.2 ft) and what you want from the lake. Fish Hook Lake matches its peer on species count.
