Tidal Wave (Six Flags St. Louis)
The Tidal Wave was a boat-based shoot-the-chutes water ride located in the Illinois section of Six Flags St. Louis in Eureka, Missouri. It opened on May 10, 1991.
The ride used 20-person boats and had a 50-foot waterfall that ended in a basin with 300,000 gallons of water, creating a wall of water 20 feet high and 80 feet wide.
It was demolished in December 2019 after being closed for the 2019 season.
