East Graham Lake vs Okabena Lake
Water quality, depth, fish species, and recreation comparison.
East Graham Lake and Okabena Lake both received the same overall water quality grade of F (Very Poor). Both are in Nobles County, Minnesota.
Both East Graham Lake and Okabena 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: East Graham Lake (F) and Okabena Lake (F) 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.
East Graham Lake
Very murky, less than 3.3 ft of visibility.
Okabena Lake
Very murky, less than 3.3 ft of visibility.
Side-by-Side Metrics
| Metric | East Graham Lake | Okabena Lake |
|---|---|---|
| Overall Grade | F (Very Poor) | F (Very Poor) |
| Water Clarity | 3.3 ft | 3.3 ft |
| Phosphorus | 189 µg/L | 166.5 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 8 ft | 16 ft |
| Surface Area | 511.33 acres | 776.05 acres |
| Public Access | Yes | Yes |
| Fish Species | 15 | 18 |
| Trophic State | eutrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade F. The tiebreakers come down to clarity (East Graham Lake: 3.3 ft, Okabena Lake: 3.3 ft) and what you want from the lake. East Graham Lake has fewer fish species than Okabena Lake.
