Esquagama Lake vs Smith Lake
Water quality, depth, fish species, and recreation comparison.
Smith Lake has a higher water quality grade (A, Excellent) than Esquagama Lake (D, Poor). Both are in St. Louis County, Minnesota.
Both Esquagama Lake and Smith 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. Smith Lake (A) is materially cleaner than Esquagama 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 — Smith 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 | Esquagama Lake | Smith Lake |
|---|---|---|
| Overall Grade | D (Poor) | A (Excellent) |
| Water Clarity | 3.5 ft | 15 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | - |
| Surface Area | 453 acres | 220 acres |
| Public Access | Unknown | Unknown |
| 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
Smith Lake wins on overall water quality with a Grade A versus Esquagama Lake's Grade D. Water clarity: 15 ft vs 3.5 ft. For fishing diversity, Smith Lake also leads with 1 species.
