Fraser Lake vs Thomas Lake
Water quality, depth, fish species, and recreation comparison.
Fraser Lake and Thomas Lake both received the same overall water quality grade of B (Good). Both are in Lake County, Minnesota.
Both Fraser Lake and Thomas 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. These two are within a letter of each other on the rubric — Fraser Lake (B) versus Thomas Lake (B). 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.
Fraser Lake
Good clarity, visible to about 11 ft.
Thomas Lake

Side-by-Side Metrics
| Metric | Fraser Lake | Thomas Lake |
|---|---|---|
| Overall Grade | B (Good) | B (Good) |
| Water Clarity | 11 ft | 14 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 105 ft | 110 ft |
| Surface Area | 695.05 acres | 1.5K acres |
| Public Access | No | No |

Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade B. The tiebreakers come down to clarity (Fraser Lake: 11 ft, Thomas Lake: 14 ft) and what you want from the lake. Fraser Lake matches its peer on species count.
