Garden Lake vs Newton Lake
Water quality, depth, fish species, and recreation comparison.
Garden Lake has a higher water quality grade (B, Good) than Newton Lake (D, Poor). Both are in Lake County, Minnesota.
Both Garden Lake and Newton 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. Garden Lake (B) is materially cleaner than Newton Lake (D). A gap that wide is unlikely to close in a single year of remediation work; it reflects multi-decade differences in the lakes themselves.
For a recreational visitor, the wider grade gap is decisive — Garden Lake is the better water-quality choice. For a researcher, the gap is the interesting part: what is different about the two watersheds, and which of those differences is mutable?

Side-by-Side Metrics
| Metric | Garden Lake | Newton Lake |
|---|---|---|
| Overall Grade | B (Good) | D (Poor) |
| Water Clarity | 5 ft | 4.5 ft |
| Phosphorus | 15 µg/L | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 55 ft | 47 ft |
| Surface Area | 653.33 acres | 516.24 acres |
| Public Access | Yes | No |
| Fish Species | 1 | 1 |
| Trophic State | mesotrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Garden Lake wins on overall water quality with a Grade B versus Newton Lake's Grade D. Water clarity: 5 ft vs 4.5 ft. For fishing diversity, Garden Lake also leads with 1 species.
