Hannen Lake vs Lake Iowa Park Beach
Water quality, depth, fish species, and recreation comparison.
Lake Iowa Park Beach has a higher water quality grade (D, Poor) than Hannen Lake (F, Very Poor). Both are in Wisconsin.
Both Hannen Lake and Lake Iowa Park Beach 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 — Hannen Lake (F) versus Lake Iowa Park Beach (D). 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.
