LD1 - Lebanon Dam South Ladder

Instream detection array in the south adult fish ladder 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 one Biomark IS-1001-Master Controler and 4x Biomark IS1001-ACNs. Addional hardware includes a cell modem, grid-supplied power configured to charge 24V battery-banks to isolate power for the Master Controller and serve as battery backup in the case of a power outage. The antenna configuration in the ladder consists of an upstream and a downstream array (making efficiency estimates possible). The upstream array is a line of three separate pass-thru antennas. Each antenna spans from pier to pier, and completely interrogates the up-stream most ladder-exit. The downstream array consists of a single antenna, which interrogates the up-stream most ladder weir. All antennas are low-profile ferrite-shielded pass-through antennas.
