Round Lake vs Shallow Lake
Water quality, depth, fish species, and recreation comparison.
Shallow Lake has a higher water quality grade (A, Excellent) than Round Lake (D, Poor). Both are in Itasca County, Minnesota.
Both Round Lake and Shallow 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. Shallow Lake (A) is materially cleaner than Round 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 — Shallow 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?
Round Lake
Murky, only visible to about 5.6 ft.
Shallow Lake
Crystal clear, you can see 16.4 ft down.
Side-by-Side Metrics
| Metric | Round Lake | Shallow Lake |
|---|---|---|
| Overall Grade | D (Poor) | A (Excellent) |
| Water Clarity | 5.6 ft | 16.4 ft |
| Phosphorus | 69 µg/L | 9 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 24 ft | 85 ft |
| Surface Area | 2.9K acres | 538.95 acres |
| Public Access | Yes | Yes |
| Fish Species | 1 | 1 |
| Trophic State | eutrophic | oligotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Shallow Lake wins on overall water quality with a Grade A versus Round Lake's Grade D. Water clarity: 16.4 ft vs 5.6 ft. For fishing diversity, Shallow Lake also leads with 1 species.
