Dixon Lake vs Shallow Lake
Water quality, depth, fish species, and recreation comparison.
Shallow Lake reads lower on nutrients and algae than Dixon Lake. Both are in Itasca County, Minnesota.
Dixon Lake and Shallow 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 readings are meaningfully apart: Shallow Lake carries clearly lower phosphorus and chlorophyll-a readings than Dixon 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?
Dixon Lake
Murky, only visible to about 6 ft.
Shallow Lake
Crystal clear, you can see 16.4 ft down.
Side-by-Side Metrics
| Metric | Dixon Lake | Shallow Lake |
|---|---|---|
| Water Clarity | 6 ft | 16.4 ft Better |
| Phosphorus | 34 µg/L | 9 µg/L Better |
| Chlorophyll-a (Algae) | 19.6 µg/L | 3.2 µg/L Better |
| Maximum Depth | 29 ft | 85 ft Better |
| Surface Area | 622 acres | 539 acres |
| Public Access | Yes | Yes |
| Fish Species | 15 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.
