North Long Lake vs Round Lake
Water quality, depth, fish species, and recreation comparison.
North Long Lake and Round Lake both received the same overall water quality grade of A (Excellent). Both are in Crow Wing County, Minnesota.
Both North Long Lake and Round Lake sit in Minnesota. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. The grades are close: North Long Lake (A) and Round 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.
North Long Lake
Good clarity, visible to about 14.6 ft.
Round Lake
Good clarity, visible to about 13.5 ft.
Side-by-Side Metrics
| Metric | North Long Lake | Round Lake |
|---|---|---|
| Overall Grade | A (Excellent) | A (Excellent) |
| Water Clarity | 14.6 ft | 13.5 ft |
| Phosphorus | 14 µg/L | 17 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 97 ft | 51 ft |
| Surface Area | 6.2K acres | 1.7K acres |
| Public Access | Yes | Yes |
| Fish Species | 1 | 1 |
| 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 (North Long Lake: 14.6 ft, Round Lake: 13.5 ft) and what you want from the lake. North Long Lake matches its peer on species count.
