Interrogation Site Metadata

BO1 - Bonneville Bradford Is. Ladder

Status: Active - Operational

Site Type: Adult Fishway | Organization: Pacific States Marine Fisheries Commission

General Operational Period: Year Round
Start Date: 3/27/2002 12:00 PM

This site monitors the Bradford Island fish ladder at Bonneville Dam. The ladder has two branches, one from the northeast side of the island and one from the southwest side, that meet below the visitor center and exit above the first powerhouse. Weir antennas are installed in most weirs in both the A and B branches. These antennas detect fish that pass through the weir orifices, but likely miss fish that pass over the weirs. There are also four antennas in the vertical slots above the counting window, that provide 99% detection efficiency. In 2018, two antennas were added that monitor the lamprey passage structure.
