Elements of the Juvenile Salmon Acoustic Telemetry System (JSATS) cabled acoustic receiver system were used at hydropower facilities for detecting juvenile salmonids implanted with JSATS microtransmitters. They were monitored in three dimensions to determining their route of passage and behavior as they passed at the facility since 2006. To investigate the underwater spatial distribution of migrating juvenile salmon between dams in open-water condition, a designed JSATS cabled receiver system was deployed at a mid-reach location (Lyons Ferry Bridge) between two dams, Little Goose Dam and Lower Monumental Dam on Snake River. Validation tests demonstrated sub-meter accuracy of 3D tracking up to 50m upstream and downstream from the Lyons Ferry Bridge piers where hydrophones were deployed. For the 2013 field application at Lyons Ferry Bridge, both detection probabilities and tracking probabilities of fish implanted were 100%.
