Ida Lake vs Lobster Lake
Water quality, depth, fish species, and recreation comparison.
Ida Lake has a higher water quality grade (A, Excellent) than Lobster Lake (B, Good). Both are in Douglas County, Minnesota.
Both Ida Lake and Lobster 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: Ida Lake (A) and Lobster 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.

Side-by-Side Metrics
| Metric | Ida Lake | Lobster Lake |
|---|---|---|
| Overall Grade | A (Excellent) | B (Good) |

| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 106 ft | 65 ft |
| Surface Area | 4.4K acres | 1.3K acres |
| Public Access | Yes | Yes |
| Fish Species | 19 | 18 |
