Water quality, depth, fish species, and recreation comparison.
Otter Lake has a higher water quality grade (D, Poor) than Lake Springfield (F, Very Poor). Both are in Wisconsin.
Both Lake Springfield and Otter Lake sit in Illinois. 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: Lake Springfield (F) and Otter Lake (D) 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 | Lake Springfield | Otter Lake |
