Interrogation Site Metadata

LD3 - Lebanon Dam Diversion Bypass

Status:   Decommissioned
Site Type: Juvenile Fish Bypass Facility  |  Organization: Oregon Dept. of Fish and Wildlife
General Operational Period: Year Round
Start Date: 4/30/2015 12:00 AM
End Date: 11/15/2018 12:00 AM

Instream detection array in the Diversion V-Screen bypass channel at Lebanon Dam on the South Santiam River, a tributary to the Willamette River. The array is one of four interrogation sites located at or near the dam. This site is monitored by 2x Biomark IS1001-ACNs synchronized for detection timing. Additional hardware includes a cell modem, grid supplied power configured to charge 24V battery-banks which isolate power to the ACN’s from the grid and serve as battery backup in the case of a power outage. This site consists of two antennas in series (making efficiency estimates possible). Each antenna is a single pass-thru antenna around the 36” HDPE bypass pipe. The pipe transports water back to the South Santiam downstream of the dam. Each antenna is a flexible low-profile pass-through antenna. The V-screen and pipe are designed to divert fish away from a diversion canal that supplies irrigation water to the area. Site is no longer active.
