Balsam Lake vs Big Round Lake
Water quality, depth, fish species, and recreation comparison.
Balsam Lake has a higher water quality grade (B, Good) than Big Round Lake (C, Fair). Both are in Polk County, Wisconsin.
Both Balsam Lake and Big Round Lake sit in Wisconsin. 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 — Balsam Lake (B) versus Big Round Lake (C). 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 | Balsam Lake | Big Round Lake |
|---|---|---|
| Overall Grade | B (Good) | C (Fair) |
| Water Clarity | 6.6 ft | 5 ft |
| Phosphorus | 16.1 µg/L | 27 µg/L |
| Chlorophyll-a (Algae) | No data | 6.9 µg/L |
| Maximum Depth | 37 ft | 17 ft |
| Surface Area | 1,901 acres | 1,014 acres |
| Public Access | Yes | Yes |
| Fish Species | 4 | 5 |
| Trophic State | mesotrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Balsam Lake wins on overall water quality with a Grade B versus Big Round Lake's Grade C. Water clarity: 6.6 ft vs 5 ft. For more fish-species variety, Big Round Lake edges ahead with 5 documented species.
