Obs-07 Lake vs Wel-01 Lake
Water quality, depth, fish species, and recreation comparison.
Wel-01 Lake has a higher water quality grade (A, Excellent) than Obs-07 Lake (F, Very Poor). Both are in Washington County, Wisconsin.
Obs-07 Lake and Wel-01 Lake are both in Indiana — 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. Wel-01 Lake (A) 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 — Wel-01 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.
Wel-01 Lake
Crystal clear, you can see 15.6 ft down.
Side-by-Side Metrics
| Metric | Obs-07 Lake | Wel-01 Lake |
|---|---|---|
| Overall Grade | F (Very Poor) | A (Excellent) |
| Water Clarity | 0.8 ft | 15.6 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | 155.9 µg/L | 2.6 µg/L |
| Maximum Depth | - | - |
| Surface Area | 86 acres | 210 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | hypereutrophic | oligotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Wel-01 Lake wins on overall water quality with a Grade A versus Obs-07 Lake's Grade F. Water clarity: 15.6 ft vs 0.8 ft. For fishing diversity, Wel-01 Lake also leads with 0 species.
