Alvin Lake vs Latoka Lake
Water quality, depth, fish species, and recreation comparison.
Latoka Lake has a higher water quality grade (A, Excellent) than Alvin Lake (B, Good). Both are in Douglas County, Minnesota.
Alvin Lake and Latoka 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. These two are within a letter of each other on the rubric — Alvin Lake (B) versus Latoka Lake (A). The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
With grades this close, the choice between the two lakes turns on non-water-quality factors: depth, fish species, public access, distance from home. The per-lake pages below cover all of those.
Alvin Lake
Good clarity, visible to about 10.5 ft.

Side-by-Side Metrics
| Metric | Alvin Lake | Latoka Lake |
|---|---|---|
