Mud Lake vs Round Lake
Water quality, depth, fish species, and recreation comparison.
Round Lake has a higher water quality grade (A, Excellent) than Mud Lake (A, Excellent). Both are in Sawyer County, Wisconsin.
Both Mud Lake and 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. The grades are close: Mud Lake (A) and Round Lake (A) 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.
Mud Lake
Good clarity, visible to about 10 ft.
Round Lake
Crystal clear, you can see 21.1 ft down.
Side-by-Side Metrics
| Metric | Mud Lake | Round Lake |
|---|---|---|
| Overall Grade | A (Excellent) | A (Excellent) |
| Water Clarity | 10 ft | 21.1 ft |
| Phosphorus | 19 µg/L | 14.4 µg/L |
| Chlorophyll-a (Algae) | No data | 1 µg/L |
| Maximum Depth | 15 ft | 74 ft |
| Surface Area | 464 acres | 3.3K acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | mesotrophic | oligotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Round Lake wins on overall water quality with a Grade A versus Mud Lake's Grade A. Water clarity: 21.1 ft vs 10 ft. For fishing diversity, Round Lake also leads with 0 species.
