From a Kansas kid to you...
Because pictures and video tell the story better than I, check out the Waka here:
Any of the galleries with "Waka" in the title will give you a better feel, minus the "Waka Event July 22", it was a busted release on an event. We basically have a ledge, and when the releases are right from Clinton Reservoir (spotty) we have one of the best play spots in the midwest.
The KWA is/was working with the Corp of Engineers to allow for modification of the ledge to make it more playable at lower flows, but that is a work in progress. The pictures of the "Waka Project" are pictures showing improvements to the access our club threw down.
Would I call it an actual play park? No. Would I be stoked to make the trip over there anytime the water is running? Every chance I get...
