An opening date of November 2017 has been set for the Epic Waters Indoor Waterpark, a new recreational facility in Grand Prairie at State Highway 161 and the Waterwood Drive.

The water park will be an indoor-outdoor venue with a retractable roof that's open year-round. For water park fans, that's a cut above its obvious competition a few miles away, Six Flags Hurricane Harbor, which is open seasonally only.

It's part of The Epic recreation center, which will feature fitness equipment, indoor tracks, a digital library, and recording studio. The complex will also have a 5,000-seat amphitheater, and more than 2 miles of trails.

The park will have nine water slides, including an outdoor wave pool, a lazy river, an activity pool, a children's area, and an arcade. There will be cabanas, a full-service grill/bar, and private party/meeting areas, both indoor and outdoor.

Three of the slides have standout features. The Lasso Loop will be the tallest indoor aqualoop in the nation. The Yellowjacket Drop is an enclosed slide you ride with an inner tube; you come out onto an open drop that sends you high up onto a wall, creating a sense of zero gravity. The Aquanaut is the first double-rider ride, letting you ride with a friend.

The water park is running a giveaway for annual passes to the park; deadline to enter is July 1.
