Fish Passage: Course 3 of 3 in a series
Hosted by Northwest Environmental Training Center

Our society is faced with one of the greatest challenges in ecological management, the projected extinction of viable anadromous salmonid populations by the end of the 21st century. Anadromous salmon and trout are not only key aspects of ecosystem function, but are vital aspects of our heritage, culture, economy, and health. Occupying both freshwater and saltwater habitats, anadromous salmonids are concurrently subjected to the multiple stressors of an increasing human population. As a result, those populating island habitats are victims of environmental degradation occurring on land, while those at sea are victims of over-fishing and subsequently depleted habitats.

Of the many stressors facing salmonids, one of the most profound and understated is human-caused barriers to their natural migration. Rather than blocking access to at least 50% of their historic range, as is currently being done on the west coast of the United States, it is imperative that we re-establish conectivity by improving fish passage routes. This workshop will provide participants with a framework to approach fish passage projects, most specifically lowhead (less than 10 meters) barriers at road crossings. We will cover barrier assessments, design, and construction, as well as the diverse array of traditional disciplines included in fish passage projects, namely civil engineering, hydrology, geomorphology, biology, and ecology.
