Other than the creek I'm not sure about what you are referring to. There is no water amusement park at this park. I believe the response that followed mine is not for this park but is instead for Bear Creek Lake State Park. They are two different parks but the description given fits that park more than Bear Creek Park which is a Denver County park.
There is a splash park next to the playground that was functioning when we were there a couple of weeks ago. Enjoy!
