Dora Lake vs Shallow Lake
Water quality, depth, fish species, and recreation comparison.
Shallow Lake reads lower on nutrients and algae than Dora Lake. Both are in Itasca County, Minnesota.
Both Dora Lake and Shallow Lake sit in Minnesota. A same-state comparison strips out the state-level water-quality regime as a variable: any differences in the readings here are about the lakes themselves, not the agencies sampling them. The readings are meaningfully apart: Shallow Lake carries clearly lower phosphorus and chlorophyll-a readings than Dora Lake. A spread that wide reflects real underlying differences, in watershed inputs, depth profiles, or monitoring rigor.
For a recreational visitor, the wider gap in the readings is decisive: Shallow Lake has the lower nutrient and algae numbers. For a researcher, the gap is the interesting part: what is different about the two watersheds, and which of those differences is mutable?
Dora Lake
Moderate clarity, visible to about 7.5 ft.
Shallow Lake

Side-by-Side Metrics
| Metric | Dora Lake | Shallow Lake |
|---|---|---|
| Water Clarity | 7.5 ft | 16.4 ft Better |
| Phosphorus | 27 µg/L | 9 µg/L Better |
| Chlorophyll-a (Algae) | 8.1 µg/L | 3.2 µg/L Better |
| Maximum Depth | 18 ft | 85 ft Better |
| Surface Area | 423 acres | 539 acres |
| Public Access | Yes | Yes |
| Fish Species | 13 Better | 12 |
| Trophic State | eutrophic | oligotrophic |
A green ✓ marks the better value for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better). Surface area and trophic state carry no tick — a bigger lake is not a better lake.
