East Vermilion Lake vs Pike Lake
Water quality, depth, fish species, and recreation comparison.
Pike Lake has a higher water quality grade (A, Excellent) than East Vermilion Lake (D, Poor). Both are in St. Louis County, Minnesota.
East Vermilion Lake and Pike 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. Pike Lake (A) is materially cleaner than East Vermilion Lake (D). 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 grade gap is decisive — Pike Lake is the better water-quality choice. 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 | East Vermilion Lake | Pike Lake |
|---|---|---|
| Overall Grade | D (Poor) | A (Excellent) |
| Water Clarity | 6.5 ft | 18 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 76 ft | 60 ft |
| Surface Area | 39.3K acres | 488.26 acres |
| Public Access | Yes | Yes |
| Fish Species | 1 | 1 |
| Trophic State | eutrophic | oligotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Pike Lake wins on overall water quality with a Grade A versus East Vermilion Lake's Grade D. Water clarity: 18 ft vs 6.5 ft. For fishing diversity, Pike Lake also leads with 1 species.
