The project proposes to use rock and boulders to create four distinct hydraulic features, each of which include an engineered wave feature. These wave features have been carefully designed to function with a constructed riffle to maintain grade control, minimize barriers to fish passage, create new opportunities for aquatic habitat, and provide enhanced whitewater recreational opportunities that lead to additional economic benefits for the community.
The waves have been designed to balance the project goals and objectives. The waves will be small in comparison to the overall width of the river, which is approximately 430-450 feet wide and they have been significantly reduced in height, width, and overall numbers from the originally proposed design. The waves are a part of the natural rock and boulder hydraulic features that contain 75% alluvial riffle habitat by area. The waves are 35-140 wide, depending on flow rates, and would allow ample fish and boat passage. Stacked stone and boulders would be used to construct waves that would but up to 1.8 feet high  and would be submerged and flows increase. The wave features contribute to the flow and habitat diversity and are essential to achieve the project purpose and create additional recreational and economic benefit opportunities.
