^I have to disagree. White Lightning was removed in 1988 for Niagara Falls. Niagara Falls was removed in 1991 for Paradise Plunge. Paradise Plunge was removed after the 2006 season to make room for Kalani Towers. All of these rides have been attached to the five story tower you see from 76.
The rides you're thinking of are Typhoon Tunnel and Hurricane Rapids. They were both removed in 2004 to make room for Raging River Rapids.
