SUN - Sunnyside Instream Array

Status:   Active - Operations Unspecified
Site Type: Instream Remote Detection System  |  Organization: Yakama Nation
General Operational Period: Year Round
Start Date: 11/4/2015 12:00 AM

The Sunnyside instream PIT tag array is located 600M below Sunnyside dam on the Yakima river. The instream portion of the array consists of 16, 20ft PVC and HDPE flat plate antennas anchored to the substrate using M4 earth anchors. Antennas and enclosures were constructed by WDFW and Yakama Nation Fisheries. The upstream row has 8 antennas spanning the wetted width of the river during most flow conditions. The downstream row was initially installed with 3 antennas (09, 0A and 0B); the remaining 5 antennas were installed October 2016. In July of 2018, all 8 antennas on the upper row were replaced with 4 inch, 20 ft HDPE flat plate antennas. The antennas are powered using ACN readers located just below the antennas in submersible enclosures. The Qube lite is located in a job box adjacent to a BOR building used for monitoring river conditions. On 10/22/2018, the Qube was upgraded to a Qube 2.0. Grid power is used to run the site.

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.

Event Log Summary

Event Date Event Type Comments
11/18/2015 3:50:00 AM General Antenna 0B started experiencing reduced Amps likely caused by flood conditions separating the connector to the submersible enclosure. Low flows will be needed to address this issue.
11/4/2015 6:00:00 PM General SUN became fully operational at this time. Tags detected prior to this time can be attributed to short test periods.
11/4/2015 6:00:00 PM General Antenna 1 was removed from sequence due to a connection problem.
