Elm Island Lake vs Ripple Lake
Water quality, depth, fish species, and recreation comparison.
Elm Island Lake and Ripple Lake both received the same overall water quality grade of D (Poor). Both are in Aitkin County, Minnesota.
Both Elm Island Lake and Ripple 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: Elm Island Lake (D) and Ripple Lake (D) 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.

Side-by-Side Metrics
| Metric | Elm Island Lake | Ripple Lake |
|---|---|---|
| Overall Grade | D (Poor) | D (Poor) |
| Water Clarity | 4 ft | 4.5 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 25 ft | 39 ft |
| Surface Area | 519.52 acres | 630.45 acres |
| Public Access | Yes | Yes |
| Fish Species | 1 | 1 |
| 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 D. The tiebreakers come down to clarity (Elm Island Lake: 4 ft, Ripple Lake: 4.5 ft) and what you want from the lake. Elm Island Lake matches its peer on species count.
