Andrusia Lake vs Drewery Lake
Water quality, depth, fish species, and recreation comparison.
Andrusia Lake reads lower on nutrients and algae than Drewery Lake. Both are in Beltrami County, Minnesota.
Both Andrusia Lake and Drewery 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. Andrusia Lake reads materially cleaner than Drewery Lake on nutrients and algae. 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 gap in the readings is decisive: Andrusia 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?
Andrusia Lake
Crystal clear, you can see 15.1 ft down.
Drewery Lake
Murky, only visible to about 3.5 ft.
Side-by-Side Metrics
| Metric | Andrusia Lake | Drewery Lake |
|---|---|---|
| Water Clarity | 15.1 ft Better | 3.5 ft |
| Phosphorus | 14.5 µg/L | 11.5 µg/L Better |
| Chlorophyll-a (Algae) | 3.6 µg/L | 2.7 µg/L Better |
| Maximum Depth | 60 ft | 120 ft Better |
| Surface Area | 1,596 acres | 15,958 acres |
| Public Access | Yes | Yes |
| Fish Species | 21 | 21 |
| 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.
