Ross Lake vs Twin Lake
Water quality, depth, fish species, and recreation comparison.
Ross Lake has a higher water quality grade (C, Fair) than Twin Lake (D, Poor). Both are in Crow Wing County, Minnesota.
Both Ross Lake and Twin 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: Ross Lake (C) and Twin 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 | Ross Lake | Twin Lake |
|---|---|---|
| Overall Grade | C (Fair) | D (Poor) |
| Water Clarity | 3.5 ft | 5 ft |
| Phosphorus | 26 µg/L | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 30 ft | 30 ft |
| Surface Area | 491.76 acres | 491.76 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
Ross Lake wins on overall water quality with a Grade C versus Twin Lake's Grade D. Water clarity: 3.5 ft vs 5 ft. For fishing diversity, Ross Lake also leads with 1 species.
