Frances Lake vs Gorman Lake
Water quality, depth, fish species, and recreation comparison.
Frances Lake has a higher water quality grade (D, Nutrient-rich) than Gorman Lake (F, Algae-prone). Both are in Le Sueur County, Minnesota.
Both Frances Lake and Gorman 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 — Frances Lake (D) versus Gorman Lake (F). 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.

Side-by-Side Metrics
| Metric | Frances Lake | Gorman Lake |
|---|---|---|
| Overall Grade | D (Nutrient-rich) Better | F (Algae-prone) |
| Water Clarity | 6 ft Better | 3.7 ft |
| Phosphorus | 23 µg/L Better | 531.5 µg/L |
| Chlorophyll-a (Algae) | 20.6 µg/L Better | 47 µg/L |
| Maximum Depth | 60 ft Better | 14 ft |
| Surface Area | 927 acres | 521 acres |
| Public Access | Yes | Yes |
| Fish Species | 16 | 16 |
| Trophic State | eutrophic | hypereutrophic |
A green ✓ marks the better value for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better). Surface area and trophic state carry no tick — a bigger lake is not a better lake.
