What is the name of the Disney water park at Walt Disney World that opened in 1989?

The Disney water park at Walt Disney World that opened in 1989 was Typhoon Lagoon.

Disney’s Typhoon Lagoon opened on June 1, 1989, at Walt Disney World Resort in Lake Buena Vista, Florida. Its theme is a storm-ravaged tropical bay, complete with shipwreck imagery, waterfalls, slides, and Mount Mayday, the artificial mountain overlooking the central lagoon.

The park’s signature attraction is its large wave pool, designed to create powerful surf-like waves. The setting imagines that a typhoon has scattered boats and tropical debris across the area, turning the aftermath of a natural disaster into a playful water-park environment.

Typhoon Lagoon was Walt Disney World’s second water park, following River Country, which opened in 1976 and later closed permanently. Blizzard Beach opened in 1995, so it cannot be the 1989 answer. Discovery Cove is a separate privately operated marine-life attraction in the Orlando area, not a Walt Disney World water park.
