A new attraction at Dollywood's Splash Country will combine a roller coaster with a water ride.
RiverRush, dubbed the state's first water coaster, is set to open in May 2013.
Dolly Parton made the announcement at the park Saturday morning in the persona of "Splash Woman."
She said, after making history with Dollywood's Wild Eagle, the country's first wing coaster, she wanted to do it again at Splash Country.
"You know me, I love making a big splash, and RiverRush is all that and a whole lot more," she said.
"Imagine being on a roller coaster with water coming at you're being propelled by water up and down on hills and valleys. It really has a coaster experience with that water feel too," said VP of Water Parks, Amy Owenby.
The coaster will be four stories tall and span more than an acre with a 1,175-foot track.
In new water park technology, the hydromagnetic coaster uses magnets and water to give you the climbs, drops, and twists of a roller coaster.
"Between the magnets and the force of the water it will push your vehicle up a track. So you're sitting in a water trough track. And the technology is pushing you around so you get that coaster experience," Owenby said.
