Pike Lake vs Sand Point Lake
Water quality, depth, fish species, and recreation comparison.
Pike Lake has a higher water quality grade (A, Excellent) than Sand Point Lake (D, Poor). Both are in St. Louis County, Minnesota.
Both Pike Lake and Sand Point Lake sit in Minnesota. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. Pike Lake (A) is materially cleaner than Sand Point 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?
Pike Lake
Crystal clear, you can see 18 ft down.
Sand Point Lake
Murky, only visible to about 6.6 ft.
Side-by-Side Metrics
| Metric | Pike Lake | Sand Point Lake |
|---|---|---|
| Overall Grade | A (Excellent) | D (Poor) |
| Water Clarity | 18 ft | 6.6 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 60 ft | 184 ft |
| Surface Area | 488.26 acres | 8.5K acres |
| Public Access | Yes | No |
| Fish Species | 1 | 1 |
| Trophic State | oligotrophic | eutrophic |
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 Sand Point Lake's Grade D. Water clarity: 18 ft vs 6.6 ft. For fishing diversity, Pike Lake also leads with 1 species.
