Lobster Lake vs Mill Lake
Water quality, depth, fish species, and recreation comparison.
Lobster Lake and Mill Lake both received the same overall water quality grade of B (Good). Both are in Douglas County, Minnesota.
Both Lobster Lake and Mill 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. The grades are close: Lobster Lake (B) and Mill Lake (B) 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.
Lobster Lake
Good clarity, visible to about 13 ft.
Mill Lake

Side-by-Side Metrics
| Metric | Lobster Lake | Mill Lake |
|---|---|---|
| Overall Grade | B (Good) | B (Good) |
| Water Clarity | 13 ft | 11 ft |
| Phosphorus | 20 µg/L | 24 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 65 ft | 40 ft |
| Surface Area | 1.3K acres | 451.12 acres |
| Public Access | Yes | Yes |
| Fish Species | 1 | 1 |
| Trophic State | mesotrophic | mesotrophic |
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 (Lobster Lake: 13 ft, Mill Lake: 11 ft) and what you want from the lake. Lobster Lake matches its peer on species count.
