What is WOKA?  The Grand River Dam Authority and the City of Siloam Springs, Arkansas have collaborated to bring a new, national-caliber whitewater adventure park to the Upper Illinois River in the Ozark Mountains. Philanthropic support from the Walton Family Foundation provided funding for the design and construction of the park.

WOKA Whitewater Park will feature heart-pumping wave action for kayakers, surfers and tubers of all skill levels. Relax and enjoy the serene beauty of nature on a stand-up paddleboard or watch the action from the waterfront spectator seating.

WOKA is a best-in-class whitewater park featuring a 1,200-foot long, 100-foot wide side channel off the Illinois River with eight drop-features for an unforgettable experience.

This park is for everyone.  From family fun to world class kayakers.
