Hydraulics - Contact Us

The WSDOT headquarter hydraulics section provides technical support, training and policy in the fields of hydraulics, fish passage, hydrology and stormwater to ensure our roadways provide a safe, effective and efficient movement of people and goods while maintaining the natural movement and treatment of water throughout our watersheds and water bodies.

In addition, the headquarter hydraulics section coordinates and provides technical guidance and policy for research in the fields of hydraulics, fish passage, hydrology and stormwater. As technical experts, it is our responsibility to the public to assess how our infrastructure will affect the quantity and quality of our watersheds and water bodies now and into the future.
