Little Goose Lock and Dam
From PTAGISWiki
Little Goose Lock and Dam, operated by the US Army Corps of Engineers, is located on the Snake River at River Mile 70.3 (River Kilometer 113) approximately 10 miles upstream from the confluence of the Palouse and Snake rivers at Lyon's Ferry. Construction was completed in 1970. Facilities include a powerhouse, spillway, navigation lock, adult fish ladder, and juvenile fish bypass system.
- Total Length: 2,655 feet (809 meters)
- Spillway Length: 512 feet (156 meters)
- Powerhouse length: 656 feet (200 meters)
- Total Generating Capacity: 810 megawatts (6 generators)
- Normal Reservoir Elevation: 633-638 feet (193-194 meters)

GOJ - Little Goose Dam Juvenile Bypass System
In operation since 1986, and in a configuration that is similar to the current one since 2002, this interrogation site interrogates and diverts PIT-tagged fish in the juvenile bypass system. Separation by Code (SbyC), smolt monitoring and smolt transportation all occur at the Juvenile Monitoring Facility. All antennas were converted to ISO from 400 KHz during the winter of 1999-2000. See the site configuration history and the current site diagram for the antenna groups described below. For assistance in determining whether a PIT-tagged fish has been transported or not, refer to FAQ:Transport vs Bypass.
- Full Flow Bypass (01-04)
- Installed in 2009, this antenna group is located between the Powerhouse and the Primary Bypass Gate. It interrogates all PIT-tagged fish in the juvenile bypass system.
- A-Separator Gate (A1-A4)
- This antenna group interrogates PIT-tagged fish that are collected from the A-side of the fish and debris separator. It is capable of triggering a gate to divert fish towards the Diversion SbyC Gate. The default route is for fish to continue through the gate towards the raceways, barge loading dock or river exit.
- 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. It is capable of triggering a gate to divert fish towards the Diversion SbyC Gate. The default route is for fish to continue through the gate towards the raceways, barge loading dock or river exit.
- Diversion SbyC Gate (C1-C4)
- This antenna group detects PIT-tagged fish that are diverted at the separator gates. It is capable of triggering a 2-way side-to-side gate that diverts fish into the SbyC Sample tanks. The default route is for fish to continue through the gate towards the Diversion River Exit antenna group as they are returned to the river.
- Diversion River Exit (91-93)
- This antenna group detects PIT-tagged fish that come through the 3-way gate as they are returned to the river.
- SbyC River Exit (E1-E3)
- This antenna group detects PIT-tagged fish that are released from the SbyC Sample Tanks and returned to the river.
- A-Raceway/River Exit (11-13)
- This antenna group detects PIT-tagged fish that are not diverted at the A-Separator gate. Depending on the facility's operational mode, fish detected here will be routed into the raceways, to the barge loading dock, or to the river exit.
- B-Raceway/River Exit (21-23)
- This antenna group detects PIT-tagged fish that are not diverted at the B-Separator gate. Depending on the facility's operational mode, fish detected here will be routed into the raceways, to the truck loading area, to the barge loading dock, or to the river exit.
- Sample Room (51-52)
- This antenna group detects PIT-tagged fish that are collected for the smolt monitoring sub-sample.
- Adult Fish Return (F1-F2)
- Installed in 2006, this antenna group detects PIT-tagged fish that are removed from the fish and debris separator and returned to the river.
