Rush Lake vs West Leaf Lake
Water quality, depth, fish species, and recreation comparison.
West Leaf Lake reads lower on nutrients and algae than Rush Lake. Both are in Otter Tail County, Minnesota.
Both Rush Lake and West Leaf 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. West Leaf Lake reads materially cleaner than Rush 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: West Leaf 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 | Rush Lake | West Leaf Lake |
|---|---|---|
| Water Clarity | 7.5 ft | 7.5 ft |
| Phosphorus | 27 µg/L | 22 µg/L Better |
| Chlorophyll-a (Algae) | 9.8 µg/L | 6.2 µg/L Better |
| Maximum Depth | 68 ft Better | 55 ft |
| Surface Area | 5,276 acres | 700 acres |
| Public Access | Yes | Yes |
| Fish Species | 19 Better | 18 |
| Trophic State | eutrophic | 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.
