Andrew Lake vs Reno Lake
Water quality, depth, fish species, and recreation comparison.
Andrew Lake has a higher water quality grade (A, Excellent) than Reno Lake (C, Fair). Both are in Minnesota.
Andrew Lake and Reno 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: Andrew Lake grades a A while Reno Lake grades a C. 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 — Andrew 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?
Andrew Lake
Good clarity, visible to about 13.9 ft.
Reno Lake

Side-by-Side Metrics
| Metric | Andrew Lake | Reno Lake |
|---|---|---|
| Overall Grade | A (Excellent) | C (Fair) |
| Water Clarity | 13.9 ft | 6.9 ft |
| Phosphorus | 16.5 µg/L | 33 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 83 ft | 23 ft |
| Surface Area | 922.77 acres | 3.8K acres |
| Public Access | Yes | Yes |
| 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
Andrew Lake wins on overall water quality with a Grade A versus Reno Lake's Grade C. Water clarity: 13.9 ft vs 6.9 ft. For fishing diversity, Andrew Lake also leads with 1 species.
