Dead Lake vs Walker Lake
Water quality, depth, fish species, and recreation comparison.
Dead Lake reads lower on nutrients and algae than Walker Lake. Both are in Otter Tail County, Minnesota.
Both Dead Lake and Walker 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: Dead Lake carries clearly lower phosphorus and chlorophyll-a readings than Walker 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: Dead 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?

Side-by-Side Metrics
| Metric | Dead Lake | Walker Lake |
|---|---|---|
| Water Clarity | 10.2 ft Better | 7.5 ft |
| Phosphorus | 20 µg/L Better | 26.5 µg/L |
| Chlorophyll-a (Algae) | 5.8 µg/L Better | 8.3 µg/L |
| Maximum Depth | 65 ft Better | 29 ft |
| Surface Area | 7,546 acres | 578 acres |
| Public Access | Yes | Yes |
| Fish Species | 18 Better | 0 |
| Trophic State | mesotrophic | eutrophic |
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.
