Chippewa Flowage Lake vs Mud Lake
Water quality, depth, fish species, and recreation comparison.
Mud Lake has a higher water quality grade (A, Excellent) than Chippewa Flowage Lake (B, Good). Both are in Sawyer County, Wisconsin.
Chippewa Flowage Lake and Mud Lake are both in Wisconsin — a same-state head-to-head where the comparison comes down to lake-specific differences in depth, watershed, and monitoring history rather than the broader state-level water-quality regime. The grades are close: Chippewa Flowage Lake (B) and Mud 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.

Side-by-Side Metrics
| Metric | Chippewa Flowage Lake | Mud Lake |
