Soak City originally opened in 1989 as a water park under the name WaterWorks featuring 15
water slides and a
lazy river ride. WaterWorks was the first themed area to be added to Kings Island since 1976, bringing the total to seven. The cost was roughly $4 million
USD. The water park was expanded in 1997 to adding a wave pool. It was renamed in 2004 to Crocodile Dundee's Boomerang Bay, and again in 2007 to Boomerang Bay dropping
Crocodile Dundee from the name. On September 2, 2011, Kings Island announced that the water park would undergo a $10-million expansion, which would include the renovation of the water park's main entrance, a revamp of the existing Lazy River ride (to "Action River"), and the construction of additional amenities. A second, larger wave pool was also added, and the water park's name was changed to Soak City for the 2012 season. ==List of attractions==
