Kayak Surfing at the Bladder Wave in Idaho Video Clips. Duration : 2.03 Mins.


Will Parham kayaking on the Payette River in Idaho during high water in May 2012. This wave is known as "The Bladder". The wave forms when water flows over the top of a 200 foot wide inflatable rubber dam. This feature is very dynamic and is dependent upon many factors including the river level, the amount of water being diverted into the canal and fish ladder, the volume and position of the air within the inflatable bladder, the amount of sediment in front of and behind the dam, the amount of suspended sediment and the consistency of the incoming flow pulses. In some years, this feature is surfable for months, while in other years, the feature never comes in at surfable levels. The feature can be consistent or it can fluctuate and go through "cycles". During these "cycles" the incoming water and the air within the bladder are constantly changing, creating a dynamic and sometimes unpredictable feature. In a matter of seconds, the wave, as well as the eddies and whirlpools, can morph and change into large hydraulics or completely disappear. The inflatable rubber dam is the result of a hydroelectric diversion installed in the mid 1990's, the formation of this surf wave is a mere coincidence. At many different levels the rubber dam can create a dangerous low head dam style hydraulic. The song is Rocketship by One Be Lo.
