Independence Lake vs Minnetonka Lake
Water quality, depth, fish species, and recreation comparison.
Minnetonka Lake has a higher water quality grade (B, Good) than Independence Lake (D, Poor). Both are in Hennepin County, Minnesota.
Independence Lake and Minnetonka Lake are both in Minnesota — a same-state head-to-head where the comparison comes down to lake-specific differences in depth, watershed, and monitoring history rather than the broader state-level water-quality regime. The grades are meaningfully apart: Minnetonka Lake grades a B while Independence 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 — Minnetonka 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 | Independence Lake | Minnetonka Lake |
|---|---|---|
| Overall Grade | D (Poor) | B (Good) |
| Water Clarity | 4.9 ft | 9.5 ft |
| Phosphorus | 66.3 µg/L | 27 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 58 ft | 113 ft |
| Surface Area | 832.02 acres | 14.2K acres |
| Public Access | Yes | Yes |
| Fish Species | 1 | 1 |
| Trophic State | eutrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Minnetonka Lake wins on overall water quality with a Grade B versus Independence Lake's Grade D. Water clarity: 9.5 ft vs 4.9 ft. For fishing diversity, Minnetonka Lake also leads with 1 species.
