Ida Lake vs Unnamed Lake
Water quality, depth, fish species, and recreation comparison.
Ida Lake has a higher water quality grade (A, Excellent) than Unnamed Lake (F, Very Poor). Both are in Douglas County, Minnesota.
Both Ida Lake and Unnamed 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: Ida Lake grades a A while Unnamed Lake grades a F. 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 — Ida 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?
Ida Lake
Crystal clear, you can see 16.5 ft down.
Unnamed Lake
Very murky, less than 3.3 ft of visibility.
Side-by-Side Metrics
| Metric | Ida Lake | Unnamed Lake |
|---|---|---|
| Overall Grade | A (Excellent) | F (Very Poor) |
| Water Clarity | 16.5 ft | 3.3 ft |
| Phosphorus | 14 µg/L | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | - |
| Surface Area | 4.4K acres | 23 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 1 | 0 |
| Trophic State | oligotrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Ida Lake wins on overall water quality with a Grade A versus Unnamed Lake's Grade F. Water clarity: 16.5 ft vs 3.3 ft. For fishing diversity, Ida Lake also leads with 1 species.
