PIT Tag Interrogation Site Details
MC1 - McNary Dam Oregon Shore Fishway
In operation since 2002, this site consists of sixteen orifice antennas installed into eight weirs below the fish counting window. These antennas interrogtate PIT-tagged fish that pass through the weir orifices. There are also two antennas integrated into the fish counting window structure, one above and one below the window. All fish must pass through these detectors as they travel past the fish counting window. Refer to the site diagram for detailed figures of the orifice weir and counting window antennas.

MC2 - McNary Dam Washington Shore Fishway
In operation since 2002, this site consists of sixteen orifice antennas installed into eight weirs below the fish counting window. These antennas interrogate PIT-tagged fish that pass through the weir orifices. In 2006 three antennas were installed in the fish counting window structure; two below the window and one above. All fish must pass through these detectors as they travel past the fish counting window. Refer to the current site diagram for figures of the orifice weir and counting window antenna structures.

MCJ - McNary Dam Juvenile Bypass System
In operation since 1987, in its current configuration and location since 2003, this site includes multiple antenna groups to detect and divert PIT-tagged fish as they move through the juvenile bypass and collection system. Collection and transportation of juvenile fish occurs at this facility, as well as smolt monitoring and Separation by Code (SbyC) activities. See the site configuration history and the current site diagram for more details about antenna group (monitor) and antenna (coil) locations within the site. For assistance in determining whether PIT-tagged fish have been transported or not, refer to FAQ:Transport vs Bypass.
- Full Flow Bypass (01-04)
- Installed in 2003. This antenna group is located between the powerhouse and the juvenile bypass facility and interrogates all PIT-tagged fish in the bypass system. These four antennas operated as MCX during 2002.
- SbyC A-Separator Gate (A1-A4)
- This antenna group interrogates PIT-tagged fish that are collected from the A-side of the fish and debris separato,r and can trigger an SbyC slide gate. By default fish pass through the gate towards the A-Raceway Diversion antenna group. If the gate is triggered for a target by an SbyC tag, the tagged fish is diverted through the A-River Diversion antenna group to the Holding Tanks.
- A-River Diversion (31-33)
- This antenna group interrogates PIT-tagged fish that are diverted at the A-Separator Gate to the Holding Tanks.
- SbyC A-Raceway Diversion (C1-C4)
- Installed in 2003. This antenna group interrogates PIT-tagged fish that pass through the A-Separator and the facility sub-sample gates, and can trigger an SbyC gate to divert fish towards the raceways. By default fish pass through this gate and return to the river through the River-2 Exit antenna group.
- A-Raceway(11-13)
- This antenna group interrogates PIT-tagged fish that are diverted to the raceways at the SbyC A-Raceway Diversion gate.
- A-Subsample (61-63)
- This antenna group interrogates PIT-tagged fish that are collected for the smolt monitoring sub-sample.
- SbyC B-Separator Gate (B1-B4)
- This antenna group interrogates PIT-tagged fish that are collected from the B-side of the fish and debris separator, and can trigger an SbyC slide gate. By default fish pass through the gate towards the B-Raceway Diversion antenna group. If the gate is triggered for a target by an SbyC tag, the tagged fish is diverted through the B-River Diversion antenna group to the Holding Tanks.
- B-River Diversion (41-43)
- This antenna group interrogates PIT-tagged fish that are diverted by the B-Separator Gate to the Holding Tanks.
- SbyC B-Raceway Diversion (D1-D4)
- Installed in 2003. This antenna group interrogates PIT-tagged fish that pass through the B-Separator and the facility sub-sample gates. It can trigger an SbyC gate to divert fish towards the raceways. By default fish pass through this gate and are returned to the river or transported (depending on the operational mode of the facility).
- B-Raceway (21-23)
- This antenna group interrogates PIT-tagged fish that are diverted to the raceways at the SbyC B-Raceway Diversion gate.
- B-Subsample (71-73)
- This antenna group interrogates PIT-tagged fish that are collected for the smolt monitoring sub-sample.
- Sample Room (51-52)
- This antenna group interrogates PIT-tagged fish that enter the Sample Room from the sub-sample tanks.
- River-1 Exit (81-84)
- This antenna group interrogates PIT-tagged fish that are returned to the river from the B-side of the secondary bypass or from the raceways.
- River-2 Exit (91-93)
- This antenna group interrogates PIT-tagged fish that pass through the A-Separator and A-Raceway Diversion gates and are returned to the river.
- Adult Fish Return (F1-F2)
- Installed in 2003. This antenna group interrogates PIT-tagged fish are removed from the fish and debris separator and returned to the river.
