Illinois vs Ohio vs Michigan splash pads
Midwest splash-pad networks compared — Chicago Park District, Ohio's equity program, and Detroit's heat-island builds.
The Great Lakes midwest trio runs a tight 140-to-150-day season and treats splash pads as the practical replacement for aging neighborhood wading pools. Illinois centers on Chicago Park District, which is replacing 1980s-era wading pools at roughly five per year. Ohio leads the trio on per-capita density thanks to an equity-prioritized installation program across Cleveland, Toledo, and Dayton. Michigan's network is smaller in raw count but tightly focused on Detroit heat-island ZIPs, with GLWA-partnered pads on tap. None of these states charges admission, all run on push-button activation, and all align on the same pool-replacement-first philosophy. The differences are about which metro you live near.

Verdict
Ohio is the clear per-capita leader and operates the most sustained equity-driven program. Illinois has the largest single-metro footprint via Chicago. Michigan is the most targeted, focusing builds where they matter most for cooling vulnerable neighborhoods. The three are within a few days of each other on operating window — climate is not a deciding factor here.
