Obs-07 Lake vs Osk-07 Lake
Water quality, depth, fish species, and recreation comparison.
Osk-07 Lake has a higher water quality grade (B, Good) than Obs-07 Lake (F, Very Poor). Both are in Wisconsin.
Both Obs-07 Lake and Osk-07 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. Osk-07 Lake (B) is materially cleaner than Obs-07 Lake (F). A gap that wide is unlikely to close in a single year of remediation work; it reflects multi-decade differences in the lakes themselves.
For a recreational visitor, the wider grade gap is decisive — Osk-07 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.
Osk-07 Lake
Murky, only visible to about 6.1 ft.
Side-by-Side Metrics
| Metric | Obs-07 Lake | Osk-07 Lake |
|---|---|---|
| Overall Grade | F (Very Poor) | B (Good) |
| Water Clarity | 0.8 ft | 6.1 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | 155.9 µg/L | 2.6 µg/L |
| Maximum Depth | - | - |
| Surface Area | 86 acres | 183.18 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
Osk-07 Lake wins on overall water quality with a Grade B versus Obs-07 Lake's Grade F. Water clarity: 6.1 ft vs 0.8 ft. For fishing diversity, Osk-07 Lake also leads with 0 species.
