Briggs Woods Lake vs Don Williams Lake
Water quality, depth, fish species, and recreation comparison.
Briggs Woods Lake and Don Williams Lake both received the same overall water quality grade of F (Very Poor). Both are in Wisconsin.
Briggs Woods Lake and Don Williams Lake are both in Iowa — 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. The grades are close: Briggs Woods Lake (F) and Don Williams Lake (F) are within one letter of each other on the LakeGrade rubric. The per-parameter sub-grades below will show where the small differences actually live.
With grades this close, the choice between the two lakes turns on non-water-quality factors: depth, fish species, public access, distance from home. The per-lake pages below cover all of those.

Side-by-Side Metrics
| Metric | Briggs Woods Lake | Don Williams Lake |
|---|---|---|
| Overall Grade | F (Very Poor) | F (Very Poor) |
| Water Clarity | 1.5 ft | 1.8 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | 59.1 µg/L | 45.2 µg/L |
| Maximum Depth | - | - |
| Surface Area | 70 acres | 160 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | hypereutrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade F. The tiebreakers come down to clarity (Briggs Woods Lake: 1.5 ft, Don Williams Lake: 1.8 ft) and what you want from the lake. Briggs Woods Lake matches its peer on species count.
