• Description:
  In 2001, the National Marine Fisheries Service completed the second year of a study to evaluate travel times of juvenile subyearling Chinook salmon Oncorynchus tshawytscha in the bypass system at McNary Dam. The first year of study indicated a delay associated with passage through the juvenile fish bypass system: median residence times within the Unit 8A gatewell were 2.8 hours. During 2001, radiotelemetry receivers were deployed to determine areas of delay within the gatewell, collection channel, and separator.
