Sioux Center is getting a better look at what the new Siouxnami Waterpark will offer when it opens in a few weeks!

The water slide tower with three slides is up, along with the diving platforms, and the zip line at the outdoor waterpark, which is being built at Sioux Center’s All Seasons Center.

“These structures have really been changing the landscape at the waterpark,” said Sioux Center City Manager Scott Wynja. “The pool painters have done a nice job, and this all means we are getting closer to everyone getting to enjoy Siouxnami!”

The waterpark will feature a lazy river with a wave feature, the aqua zip-line that will take riders out over the deep pool, both low and high diving boards, a tube water slide, a body water slide, a speed water slide, an underwater bench to relax on, a climbing wall, a 12-foot floating alligator, and lots of pool space to enjoy the water. 

“Our goal with Siouxnami has always been to make it great for all ages, and we think we’ve done that,” said All Seasons Center director Dave Ruter. “It’s amazing we will have this opportunity in Sioux Center. I’m excited for the kids, adults and families that are going to come and experience Siouxnami!”

The waterpark is being built to connect to the existing outdoor pools and the indoor pools at the All Seasons Center. The outdoor area includes a zero-depth entry children's pool, splash features, and slide pool with a waterfall. The indoor water waterpark area offers a hot tub, water slides, lap lanes, diving boards, and zero-depth children's splash area. These existing pools are open for summer hours.
