PIT Tag Interrogation Sites Summary
Interrogation sites have been in operation at Bonneville Dam since 1996. There are currently six sites in operation; five sites have been retired or replaced. Four of the current sites are located in adult fishways; two sites are located in juvenile fish bypass systems. Separation by Code (SbyC) activities occur at two sites.

Downstream Migration Interrogation Sites
B2J - Bonneville Dam Powerhouse 2 Juvenile Bypass System
- In operation since 1996, and at the current location since 1999, this is one of two downstream migrant interrogation sites at Bonneville Dam. The Powerhouse 2 Juvenile Bypass System conveys fish from the second powerhouse through a 4-ft diameter pipe to the Juvenile Monitoring Facility (JMF) about 2 miles downstream. Seven antenna groups (monitors) are capable of detecting PIT tags and/or triggering Separation by Code diversion gates, depending on the operational status of the JMF. See the current site diagram for the antenna groups that are described below.
- Full Flow Bypass (01-04)
- In place since 2006, this antenna group interrogates PIT-tagged fish in the bypass system. If the facility is operating in primary bypass mode, this is the only antenna group fish pass through.
- SbyC Separator Gate (A1-A4)
- In place since 1999, this antenna group interrogates PIT-tagged fish that are collected from the smolt separator.
- River Exit (Antenna IDs 81-82)
- In place since 1999, this antenna group interrogates PIT-tagged fish that pass through the SbyC Separator Gate and facility smolt monitoring sub-sample gate to the river exit; this is the normal route of passage when the facility is in secondary bypass mode.
- SbyC East Tank (E1-E2)
- In place since 1999, this antenna group interrogates PIT-tagged fish that are diverted at the SbyC Separator Gate into the East Tank.
- SbyC West Tank (F1-F2)
- In place since 1999, this antenna group interrogates PIT-tagged fish that are diverted at the SbyC Separator Gate into the West Tank.
- Sample Room (51-52)
- In place since 2001, this antenna group interrogates PIT-tagged fish that are collected for the smolt monitoring sub-sample.
- Sample & SbyC Exit (91-93)
- In place since 1999, this antenna group interrogates PIT-tagged fish that are released from the Recovery Tank to the river.

BCC - Bonneville Dam Powerhouse 2 Corner Collector
- Operating since 2006, this site consists of a single antenna located in a flume downstream of a former ice and trash chute that has been modified to improve downstream fish passage. The corner collector intake is located at the southeastern corner of Powerhouse 2 and can allow approximately 5,000 cfs of water to flow into the chute. The antenna is located about 1,300 feet downstream from Powerhouse 2 and encircles the corner collector flume (about 15 ft square). It interrogates PIT-tagged fish that have entered the Powerhouse 2 corner collector flume.

BVX & B1J - Bonneville Dam DSM1 Flat Plate Detector
- Operating from 1996 - 2003, this site consisted of a flat plate detector installed over the smolt trap in the downstream migration channel of Powerhouse 1. PIT-tagged fish that entered the downstream migration channel were detected at this site unless the smolt trap was operating. The site was operated as experimental site BVX by the National Marine Fisheries Service until 2003, when operations were taken over by PSMFC and the site was renamed to B1J. At the end of 2003, the US Army Corps of Engineers decided to disable passage of juvenile salmonids through the Powerhouse 1 downstream migration channel, and operation of the interrogation site was discontinued.

Upstream Migration Interrogation sites
BO1 - Bradford Island Adult Fishway
- Operating since 2002, this site includes weir orifice antennas deployed in both branches of the Bradford Island Adult Fishway and vertical slot antennas above the fish counting window. The entrance to the A Branch is below the first powerhouse; the B Branch entrance is below the spillway. There are sixteen weir orifice antennas in each branch that interrogate PIT-tagged fish that move through those orifices. The four vertical slot antennas interrogate PIT-tagged fish that move between the counting window and the fishway exit. See the site diagram for figures depicting notched weir and vertical slot details.

- Operating since 1998, in its current configuration since 2003, this site consists of detectors in installed in the Washington Shore Adult Fishway and the Adult Fish Facility (AFF). It is equipped with eight weir orifice antennas below the AFF, sixteen above the AFF, and eight antennas inside the AFF for Signal by Code activities. Prior to 2003 the detectors in the AFF were operated as site B2A and those in the fishway were operated as site BWL.
