Out of the majority of parks in Phoenix metro and surrounding areas this is one of my favorite parks. The park is normally clean by the play ground area. This is the only public park that I know of that has the splash pad open till the first week of October. Which is great because we all know Arizona doesn't cool down till November.
The man made pond/lake is a few hundred feet away from the playground which I never seen a problem with any kid of your paying attention to them. The water gets pretty dirty at times from people not throwing the trash in the trash cans.
However the fishing scene is great because everyone pretty much gives you your space. Make sure you bring a chair not a blanket because there are always ants and any holes so watch the little ones.
