Fish Hook Lake vs Long Lake
Water quality, depth, fish species, and recreation comparison.
Fish Hook Lake and Long Lake both received the same overall water quality grade of A (Excellent). 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 grades are close: Fish Hook Lake (A) and Long Lake (A) are within one letter of each other on the LakeGrade rubric. The per-parameter sub-grades below will show where the small differences actually live.
With grades 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 |
|---|---|---|
| Overall Grade | A (Excellent) | A (Excellent) |
| Water Clarity | 10.2 ft | 11.2 ft |
| Phosphorus | 13 µg/L | 10 µg/L |
| Chlorophyll-a (Algae) | 4.5 µg/L | 4.5 µg/L |
| Maximum Depth | 76 ft | 135 ft |
| Surface Area | 1,643 acres | 1,926 acres |
| Public Access | Yes | Yes |
| Fish Species | 14 | 14 |
| Trophic State | mesotrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
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.
