May 15, 3:30 - 4:30 (Seminar) and 4:30 - 5:30 (Networking) | PSU Urban Center, Parson's Gallery (Room 212) | UPP Science Seminar and Networking - Synthesis of Chinook Salmon Habitat Throughout the Willamette Basin The Willamette Basin is home to at least 69 species of fish, including spring-run Chinook salmon (Oncorhynchus tshawytscha) which is listed as “threatened” under the U.S. Endangered Species Act. Chinook salmon and other aquatic organisms rely on the availability of suitable habitat, such as water depth, velocity, sediment size, and temperature, to fulfill various aspects of their life cycle. These habitat components are related to streamflow, which in the Willamette Basin is managed, in part, by 13 U.S. Army Corps of Engineers dams. This presentation will highlight work conducted to understand Chinook salmon habitat dynamics and how streamflow management affects rearing and spawning habitat for Chinook salmon in the upper Willamette Basin. | James White is a hydrologist with the U.S. Geological Survey Oregon Water Science Center, where he has worked for the past 10 years. His work focuses on the intersection of channel hydraulics, aquatic ecosystems, and water management. |
