Olp-04 Lake vs Wpa-04 Lake
Water quality, depth, fish species, and recreation comparison.
Wpa-04 Lake has a higher water quality grade (C, Fair) than Olp-04 Lake (F, Very Poor). Both are in Dubois County, Wisconsin.
Both Olp-04 Lake and Wpa-04 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: Wpa-04 Lake grades a C while Olp-04 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 — Wpa-04 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?

Side-by-Side Metrics
| Metric | Olp-04 Lake | Wpa-04 Lake |
|---|---|---|
| Overall Grade | F (Very Poor) | C (Fair) |
| Water Clarity | 2.8 ft | 1.5 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | 48.1 µg/L | 5.3 µg/L |
| Maximum Depth | - | - |
| Surface Area | 9.8 acres | 180 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | eutrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Wpa-04 Lake wins on overall water quality with a Grade C versus Olp-04 Lake's Grade F. Water clarity: 1.5 ft vs 2.8 ft. For fishing diversity, Wpa-04 Lake also leads with 0 species.
