Lobster Lake vs Miltona Lake
Water quality, depth, fish species, and recreation comparison.
Lobster Lake and Miltona Lake both received the same overall water quality grade of A (Excellent). Both are in Douglas County, Minnesota.
Both Lobster Lake and Miltona 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 — Lobster Lake (A) versus Miltona 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.
Lobster Lake
Good clarity, visible to about 13 ft.
Miltona Lake
Crystal clear, you can see 18.7 ft down.
Side-by-Side Metrics
| Metric | Lobster Lake | Miltona Lake |
|---|---|---|
| Overall Grade | A (Excellent) | A (Excellent) |
| Water Clarity | 13 ft | 18.7 ft |
| Phosphorus | 20.5 µg/L | 18 µg/L |
| Chlorophyll-a (Algae) | 3.6 µg/L | 2.9 µg/L |
| Maximum Depth | 65 ft | 105 ft |
| Surface Area | 1,334 acres | 5,731 acres |
| Public Access | Yes | Yes |
| Fish Species | 18 | 19 |
| 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 A. The tiebreakers come down to clarity (Lobster Lake: 13 ft, Miltona Lake: 18.7 ft) and what you want from the lake. Lobster Lake has fewer fish species than Miltona Lake.
