Even though it was privately owned, the Rockford Park District was involved in planning.

In 1986, Magic Waters private ownership filed for Chapter 11 bankruptcy due to low attendance.

In 2004, The Abyss, a dark tunnel tube slide 5 stories high was added to the park.

The ride twists and turns multiple times before it splashes the rider into a pool of daylight.

The ride is 75 feet tall and was built by Rockford Structures Construction Co.[11] In July 2014, a dozen lawsuits were filed against Magic Waters and the Rockford Park District due to the now removed ride Splash Blaster over back injuries.

[13] On October 9, 2018, Six Flags announced that they had reached an agreement with Rockford Park District to operate Magic Waters Waterpark starting in the spring of 2019 for 10 years.

It was also announced that Tidal Wave would be added to the park as the first "tailspin" slide in the Midwest by WhiteWater West.
