Summer entertainment continues in Plymouth on Wednesday, when Shockwaves, a water ski show featuring the Shakopee-Prior Lake Water Ski Association, starts at 7 p.m. at Parkers Lake Park.

Shockwaves was founded in 1957 by a man just trying to raise enough money to build a water ski jump. Now it boasts more than 180 members and has performed across the Midwest and into Canada. This year's production is entitled "Disco Ski-ver," featuring two announcers — one who loves rock n' roll, one who loves disco — bantering back and forth on the shore as music plays and the water skiers perform.

The water-skiers and wakeboarders showcase everything from on-shore dance routines to high-flying jumps and pyramids in their colorful costumes, pulled behind one of the three towboats used during the show. The show team isn't made up of strictly performers; there's the spotters, drivers, announcers and audio technicians that help pull it all together. Shockwaves practices twice a week starting in the spring at a lake they've leased exclusively from the city of Shakopee since 2002.

"The team is like a big family. When you spend as much time as we do together, we become like brothers and sisters. And we all do it for the same reason: the love of water skiing," said Mike Aretz, show director for Shockwaves.

On the shore, popcorn and ice cream will be sold, and families are encouraged to pack a picnic. The event is free and open to the public, and it returns to Parkers Lake for an encore performance Aug. 7. Viewers are encouraged to arrive early, because space is limited.
