Okabena Lake vs Round Lake
Water quality, depth, fish species, and recreation comparison.
Okabena Lake and Round Lake read the same on nutrients and algae. Both are in Minnesota.
Okabena 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. These two sit close on the readings, Okabena Lake versus Round 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.
Okabena Lake
Very murky, less than 3.3 ft of visibility.
Round Lake
Very murky, less than 2 ft of visibility.
Side-by-Side Metrics
| Metric | Okabena Lake | Round Lake |
|---|---|---|
| Water Clarity | 3.3 ft Better | 2 ft |
| Phosphorus | 166.5 µg/L | 77 µg/L Better |
| Chlorophyll-a (Algae) | 24.1 µg/L | 14.7 µg/L Better |
| Maximum Depth | 16 ft Better | 9 ft |
| Surface Area | 776 acres | 930 acres |
| Public Access | Yes | Yes |
| Fish Species | 18 Better | 17 |
| Trophic State | eutrophic | eutrophic |
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 D. The tiebreakers come down to clarity (Okabena Lake: 3.3 ft, Round Lake: 2 ft) and what you want from the lake. Okabena Lake supports more documented fish species.
