Burke was pronounced dead at Advocate Christ Medical Center in Oak Lawn. An autopsy determined she drowned.
It's unclear how long Burke was underwater before she was found.
"Any time you hear about a drowning it makes you sick to your stomach and makes you want to keep a closer eye on your kids, especially around water," said Ali Myers, parent.
Evergreen Aqua Park has been a popular water park for 50 years. There are four pools, including a training pool for small children. According to park rules, children under eight must be accompanied by an adult.
Parents and neighbors in the area are upset to hear about the loss of the young girl and say it's a good reminder to be extra careful this summer with kids and pools.
"For parents, don't get comfortable trusting people to watch your children. We trust them to a certain extent, but then we have to take responsibility," said Michelle Hudson, parent.
"Obviously, it can happen so fast, so you have to be right there, keeping a close eye, because it just takes seconds, too late," said Myers.
Burke lived in Chicago's Beverly neighborhood. Her father is a paramedic with the Chicago Fire Department.
An autopsy for Burke is scheduled for Monday.
There is no word on when the park will reopen.
