Gladstone Lake vs Round Lake
Water quality, depth, fish species, and recreation comparison.
Gladstone Lake and Round Lake read the same on nutrients and algae. Both are in Crow Wing County, Minnesota.
Gladstone Lake and Round 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: Gladstone Lake and Round 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.
Round Lake
Good clarity, visible to about 13.5 ft.
Side-by-Side Metrics
| Metric | Gladstone Lake | Round Lake |
|---|---|---|
| Water Clarity | 10.5 ft | 13.5 ft Better |
| Phosphorus | 17 µg/L | 17 µg/L |
| Chlorophyll-a (Algae) | 4.8 µg/L | 2.7 µg/L Better |
| Maximum Depth | 36 ft | 51 ft Better |
| Surface Area | 437 acres | 1,650 acres |
| Public Access | Yes | Yes |
| Fish Species | 15 | 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 (Gladstone Lake: 10.5 ft, Round Lake: 13.5 ft) and what you want from the lake. Gladstone Lake has fewer fish species than Round Lake.
