Camp Lake vs Sullivan Lake
Water quality, depth, fish species, and recreation comparison.
Sullivan Lake reads lower on nutrients and algae than Camp Lake. Both are in Minnesota.
Both Camp Lake and Sullivan 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: Sullivan Lake carries clearly lower phosphorus and chlorophyll-a readings than Camp 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: Sullivan 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?
Camp Lake
Moderate clarity, visible to about 8.3 ft.
Sullivan Lake
Good clarity, visible to about 10.8 ft.
Side-by-Side Metrics
| Metric | Camp Lake | Sullivan Lake |
|---|---|---|
| Water Clarity | 8.3 ft | 10.8 ft Better |
| Phosphorus | 19.5 µg/L | 14 µg/L Better |
| Chlorophyll-a (Algae) | 10.4 µg/L | 5 µg/L Better |
| Maximum Depth | 42 ft | 57 ft Better |
| Surface Area | 534 acres | 1,103 acres |
| Public Access | Yes | Yes |
| Fish Species | 12 | 18 Better |
| Trophic State | mesotrophic | mesotrophic |
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.
