Interrogation Site Metadata
SSJ - SUNNYSIDE JUVENILE
Status: Active - Operations UnspecifiedGeneral Operational Period: Seasonally
Start Date: 4/11/1991 4:21 PM
The current Sunnyside juvenile bypass site was installed March 2018. It is located at Sunnyside Dam in the canal starting about 320 meters below the headgate. Three 19ft x 8ft passthrough antennas (antennas 1, 2 and 3) are mounted below each of the three trash rack bays in an attempt to monitor the majority of the water column. The trash rack antennas were constructed using 1 inch Pex and are fixed to a 4in x 6in wooden frame. Two additional passthrough antennas (antennas 4 and 5) are located at each of the bypass entrances ~100 meters downstream of the trash racks. Both of the bypass antennas were constructed using 1/2 inch conduit and are mounted to 2in x 4in wooden frames. All antennas at SSJ are powered using IS1001 ACN readers. Each reader is daisy chained with CAN bus cable and routed back to a IS1001 Master Controller positioned between the trash racks and bypass entrance. A completely different interrogation site was operated in the same location for a few months in 1991 by NMFS.

Configuration
Configuration metadata includes details about the equipment used at the site to detect and record PIT tags. A new configuration sequence record is created when equipment is added or removed from the site and the period of time it was active. A configuration sequence without an End Date is currently active.
