Brushy Creek Lake vs Don Williams Lake
Water quality, depth, fish species, and recreation comparison.
Brushy Creek Lake and Don Williams Lake both received the same overall water quality grade of F (Very Poor). Both are in Wisconsin.
Both Brushy Creek Lake and Don Williams Lake sit in Iowa. 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. These two are within a letter of each other on the rubric — Brushy Creek Lake (F) versus Don Williams Lake (F). The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
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.

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 (Brushy Creek Lake: 2.8 ft, Don Williams Lake: 1.8 ft) and what you want from the lake. Brushy Creek Lake matches its peer on species count.
