Surf’s up. Surf’s down.
Whitewater boaters and spectators were doing double takes at the wave diversion at the Ray Neef M.D. Boise River Recreation Park over the last week.
One day there would be a wave across the river and the next it was gone with water pouring through one slot in the diversion.
Workers, including a diver, have been clearing sediment and other debris from the Wave Shaper devices and flashboards in the diversion that accumulated from high water, said Amy Stahl, a spokesperson with Boise Parks and Recreation.
Sediment from where construction crews were working in the river bottom during the winter, and also debris from upstream, clogged the mechanisms on the surfing diversion.
Work is continuing this week to remove debris and the waves at the diversion will continue to change as adjustments are made. Surfers are still using the area.
Not only rocks and gravel were clogging the mechanisms. Crews found golf balls, trash and piles of leaves in the structure.
The sediment and debris prevented the flashboards or flaps that create waves from being lowered in the river.
The first phase of the river park was built this winter and whitewater boaters are using it daily. Besides the kayaker play areas, the park also has launch ramps, a viewpoint, new paths along the river and newly planted vegetation.
The river park was funded by the city of Boise, the J.A. and Kathryn Albertson Foundation and other private donations and grants.
A dedication of the park is planned June 28.
