Juvenile Chinook Salmon Outmigration JSATS Telemetry Tagging and Detections in the Klamath River

We conducted a study to assess the timing of outmigration and survival of juvenile Chinook salmon in relation to managed water flows in the Klamath River. Juvenile salmon were implanted with acoustic telemetry transmitters, and their movements were tracked using remote receivers deployed throughout the lower Klamath River, from Iron Gate Dam to the river’s mouth. Because transmitter battery life may not last the entire duration fish spend in the study area, we also conducted a tag life experiment. This experiment helps distinguish between tag failure and fish mortality in survival analyses. The dataset includes four tables: Receiver and Release Site Data – Locations of telemetry receivers and fish release sites. Tagging Data – Tagging and release sites, fish size, tag descriptions, fish source, and release datetime. Detection Data – Date and time of tag detections as fish moved through the river. Tag Life Data – Acoustic transmitter information,last detection dates and times and calculated taglife of transmitters monitored in a hatchery tank during the battery life experiment.
