Obs-07 Lake vs Wem-08 Lake
Water quality, depth, fish species, and recreation comparison.
Wem-08 Lake has a higher water quality grade (A, Excellent) than Obs-07 Lake (F, Very Poor). Both are in Washington County, Wisconsin.
Both Obs-07 Lake and Wem-08 Lake sit in Indiana. 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 meaningfully apart: Wem-08 Lake grades a A while Obs-07 Lake grades a F. That two-letter spread reflects real underlying differences — different watershed inputs, different depth profiles, or different monitoring rigor.
For a recreational visitor, the wider grade gap is decisive — Wem-08 Lake is the better water-quality choice. For a researcher, the gap is the interesting part: what is different about the two watersheds, and which of those differences is mutable?
Obs-07 Lake
Very murky, less than 0.8 ft of visibility.
Wem-08 Lake
Good clarity, visible to about 10 ft.
Side-by-Side Metrics
| Metric | Obs-07 Lake | Wem-08 Lake |
|---|---|---|
| Overall Grade | F (Very Poor) | A (Excellent) |
| Water Clarity | 0.8 ft | 10 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | 155.9 µg/L | 3.1 µg/L |
| Maximum Depth | - | - |
| Surface Area | 86 acres | 48 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | hypereutrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Wem-08 Lake wins on overall water quality with a Grade A versus Obs-07 Lake's Grade F. Water clarity: 10 ft vs 0.8 ft. For fishing diversity, Wem-08 Lake also leads with 0 species.
