CLINTON — For the first time since the early 1990s, Riverboat Days will feature the performance of a ski show on the river.

On July 7 from 5 to 7 p.m., the Waterhawks Ski Team will perform. Spectators will be able to watch the show from the dike along Riverview Drive, south of the Clinton Area Showboat Theatre.

The Waterhawks’ show consists of barefoot and four-tier pyramids, aerial jumps, wakeboarding and a 20-girl slalom ballet line.

The Waterhawks Ski Team was organized in 1958 with 16 members who promoted ski safety, boating and family fun on the water.

In 1993, the team purchased Eagle Lake in Evansdale, where they perform a show every Sunday.

The team has grown to more than 100 members, ranging in ages from 5 to 60. The team consists of about 50 skiers and a large support team.

The team has been very successful in competitive events. It has won the state titles in three-event skiing and show team skiing for several years.

The team finished in the top 10 at the National Ski Show Championships in 2004, 2005 and 2006, and their seventh-place finish in 2005 was the best finish ever for an Iowa-based team.

During the 1980s, ski shows were common at Riverboat Days. The Ski-Daddlers ski club would host another area ski group, and the two groups would demonstrate their skills in a two-part ski show.

Bernie Holtkamp, an executive director with the Clinton Riverboat Days Board of Directors, said that he is excited to welcome the Waterhawks Ski Team to the festival.

He noted previous ski shows have been very well received by attendees.

The idea for the ski show came out of a lunch meeting between Holtkamp and Jim McGraw, owner of Happy Joe’s Pizza in Clinton, and sponsor of the event.

McGraw said he and Holtkamp discussed ways to bring more “pizzazz” to Riverboat Days, and that the Waterhawks Ski team seemed like a natural fit.

“It is Riverboat Days,” McGraw said. “The name, of course, suggests that it is part of the river and riverfront. And so having a water event is a real good deal for them.”

Holtkamp noted McGraw served as commodore of Riverboat Days in 1984 and served on the festival’s board for several years.

He said McGraw has always been a great supporter and advocate for Riverboat Days.

“We’re proud to say he’s been a friend of the festival,” Holtkamp added.
