Red Haw Lake vs Williamson Pond Max Depth

Water quality, depth, fish species, and recreation comparison.

Red Haw Lake and Williamson Pond Max Depth both received the same overall water quality grade of F (Very Poor). Both are in Lucas County, Wisconsin.

Red Haw Lake and Williamson Pond Max Depth 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. These two are within a letter of each other on the rubric — Red Haw Lake (F) versus Williamson Pond Max Depth (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 (Red Haw Lake: 3.1 ft, Williamson Pond Max Depth: 1.6 ft) and what you want from the lake. Red Haw Lake matches its peer on species count.
