LD4 - Lebanon Dam Spillway

Instream detection array at the Lebanon Dam Spillway. Lebanon Dam is located near Lebanon Oregon on the South Santiam River, a tributary to the Wilammette River. The array is one of four interrogation sites located at or near the dam. This site is monitored by two synchronized Biomark IS-1001-Master Controllers and 15x Biomark IS1001-ACNs. Additional hardware at the site includes cell modems for data-transfer, grid supplied power charging 24V battery-banks to isolate grid power from the Master Controller and serve as backup in the case of a power outage. The antenna configuration is a single line of fifteen antennas on the upstream sill of the Obemeyer Weir, each approximately twenty feet in length (efficiency estimates are not possible without direct tag-testing). The antennas are designed to detect fish as the water is beginning to accelerate off the spillway. Antennas are ferrite shielded to prevent interference from the weir and rebar. The site is on the city of Albany property.
