Farm Lake vs Newton Lake
Water quality, depth, fish species, and recreation comparison.
Farm Lake has a higher water quality grade (B, Good) than Newton Lake (D, Poor). Both are in Lake County, Minnesota.
Both Farm 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. The grades are meaningfully apart: Farm Lake grades a B while Newton Lake grades a D. That two-letter spread reflects real underlying differences — different watershed inputs, different depth profiles, or different monitoring rigor.
For a recreational visitor, the wider grade gap is decisive — Farm 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 | Farm Lake | Newton Lake |
|---|---|---|
| Overall Grade | B (Good) | D (Poor) |
| Water Clarity | 5.5 ft | 4.5 ft |
| Phosphorus | 15 µg/L | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 56 ft | 47 ft |
| Surface Area | 1.3K 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
Farm Lake wins on overall water quality with a Grade B versus Newton Lake's Grade D. Water clarity: 5.5 ft vs 4.5 ft. For fishing diversity, Farm Lake also leads with 1 species.
