There isn't a thread like this so I decided to create one to make it easier to find splash pads and waterparks made by the community.

Unfortunately I don't have any better screenshots, but there is a splash pad area for the toddlers and kids, a big pool for everyone, a play area for kids with a water slider and treehouse, and a relax area for adults with jacuzzi and massage table.
Wow impressive.
Awesome.

Here's a community pool I have in Oasis Springs. I have added to it all water activities, including slide and splash pads.
