Evaluation of Two Spill Treatments at John Day Dam on Acoustically Tagged Juvenile Salmonids

The objective of this project was to evaluate the effect of two spill treatments on fish-passage efficiency, spill efficiency, spill effectiveness, dam survival, and route-specific survival of juvenile salmondids tagged with the Juvenile Salmon Acoustic Telemetry System (JSATS) at John Day Dam (JDA) in 2009.
