White Water Bay's sister park, Frontier City, last year opened Wild West Water Works, a $3 million water attraction with eight slides and a 1,000-gallon tipping bucket.
Riddles said those developments weren't a factor in White Water Bay's decision to add rides.
“We're still the largest water park in the state and we try to set the trends,” he said.
White Water Bay opens May 18 for the 2013 season. One-day admission is $34.99 for adults, up from $25.99 last year. Double park season passes, which include Frontier City, are $69.99.
