Thread Lake Central Basin vs Thread Lake
Water quality, depth, fish species, and recreation comparison.
Thread Lake Central Basin has a higher water quality grade (C, Fair) than Thread Lake (F, Very Poor). Both are in Genesee County, Wisconsin.
Both Thread Lake Central Basin and Thread Lake sit in Michigan. 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: Thread Lake Central Basin grades a C while Thread 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 — Thread Lake Central Basin 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 | Thread Lake Central Basin | Thread Lake |
|---|---|---|
| Overall Grade | C (Fair) | F (Very Poor) |
| Water Clarity | 1.8 ft | 1.8 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | 7.6 µg/L | No data |
| Maximum Depth | - | - |
| Surface Area | 80 acres | 80 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
Thread Lake Central Basin wins on overall water quality with a Grade C versus Thread Lake's Grade F. Water clarity: 1.8 ft vs 1.8 ft. For fishing diversity, Thread Lake Central Basin also leads with 0 species.
