Early Detection Monitoring May Not Be Sufficient for Invasive Mussels in the Columbia River Basin
The ecological and economic costs of an invasive quagga or zebra mussel infestation in the Pacific Northwest of the U.S. would be significant. The development of invasive mussel monitoring programs in the Pacific Northwest provides a unique opportunity to evaluate a regional invasive species detection effort early in its development. Although efforts are underway to monitor for the presence of...
Salmonid Population and Life History Research in Tributary Stream and River Habitats and Response to Dam Removal
Juvenile anadromous salmonids all spend some portion of their lives in freshwater. This time may vary from days to years depending upon species and run. Spring Chinook Salmon and Coho salmon generally spend one year in freshwater and Steelhead may spend up to five years in freshwater prior to beginning their journey to sea. Several projects at WFRC – CRRL are investigating populations, life...
Contaminants in Puget Sound Forage Fishes and Impacts to the Marine Food Web
Toxic chemical pollutants have been released into Puget Sound for decades by human activities. There’s a wide range of contaminants, from persistent compounds like polychlorinated biphenyls (PCBs) and flame retardants to contaminants of emerging concern. Aquatic species can be exposed to and accumulate contaminants, causing disease or disruption of biological processes like growth or reproduction...
Scientific Support of Salmon and Steelhead Reintroductions in Impounded River Basins of the Pacific Northwest
Salmon and steelhead populations in the Pacific Northwest were severely affected by hydropower development that occurred during the first half of the 20th century. Impassable dams were constructed on many rivers throughout the region which prevented returning adult salmonids from accessing important habitats where spawning and rearing historically occurred. In the past two decades resource...

Steelhead Life History Study in White Creek on the Yakama Nation Reservation
Fishery biologists from the U.S. Geological Survey have teamed with fishery biologists from the Yakama Nation to conduct a life history study of the juvenile steelhead using small electronic tags.
