Fraser Lake vs Strup Lake
Water quality, depth, fish species, and recreation comparison.
Fraser Lake has a higher water quality grade (B, Good) than Strup Lake (C, Fair). Both are in Lake County, Minnesota.
Fraser Lake and Strup 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. The grades are close: Fraser Lake (B) and Strup Lake (C) are within one letter of each other on the LakeGrade rubric. The per-parameter sub-grades below will show where the small differences actually live.
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.
Fraser Lake
Good clarity, visible to about 11 ft.
Strup Lake

Side-by-Side Metrics
| Metric | Fraser Lake | Strup Lake |
|---|---|---|
