This hands-on workshop assisted engineers, hydrologists, biologists, and environmental planners who are involved in the design and implementation of fish passage projects. 

The cumulative effect of culverts, road crossings, and other structures up and down the coast has impaired fish passage greatly. The need exists to train county personnel, engineers, CalTrans, hydrologists, and fisheries biologists how to remove barriers, large and small, as an essential part of recovering coastal salmon and steelhead.
