LD4 - Lebanon Dam Spillway

Status:   Decommissioned
Site Type: Juvenile Fish Bypass Facility  |  Organization: Oregon Dept. of Fish and Wildlife
General Operational Period: Year Round
Start Date: 10/2/2015 12:00 AM
End Date: 11/13/2018 12:00 AM

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. Site is no longer active.

Configuration

Configuration metadata includes details about the equipment used at the site to detect and record PIT tags. A new configuration sequence record is created when equipment is added or removed from the site and the period of time it was active. A configuration sequence without an End Date is currently active.

Event Log Summary

Event Date Event Type Comments
11/30/2018 3:43:00 PM SiteDown Flooding badly damaged site, beyond immediate repair. Plans to repair site in spring/summer of 2021.
9/10/2016 12:00:00 AM General Antenna 13 down
8/29/2016 12:00:00 AM General Antennas 1, 2, and 4 back in operation. Antenna # 3 is still down. Antenna 1 has high noise due to a bad CANBUS cable connection and it won't be fixed until winter.
8/26/2016 12:00:00 AM General Antennas 1-4 down again
8/24/2016 12:00:00 AM General Antennas 12-15 are back in operation
8/20/2016 12:00:00 AM General Antennas #3, 13, and 14 are down again
8/17/2016 12:00:00 AM SiteUp Work was done on the site today to get antenna's up and running. Antennas #1-4, 13, and 14 are operational. Antenna's 12 and 15 are offline for additional maintenance. Antenna # 5-11 are out indefinitely.
2/29/2016 12:00:00 AM SiteUp Antenna #15 back in operation. Antenna's 5-11 decommissioned for the foreseeable future due to damage sustained by high flows and the large log hitting the weir.
12/29/2015 3:00:00 AM SiteDown Site Down. South side antennas will likely be restored week of 1/4/2016 will replacement of master controller and severed canbus cable from the south side. Therefore restoring the southern 7 antennas on the spillway. However, a four foot diameter tree had the audacity to float downstream and remove two pier-mounted ACN's from the northern array. This has caused a short in the Northern canbus cable, and until that is repaired, it is unlikely that the remaining 8 antennas (of 15) will function. Unknown repair date, as flow must be minimal (< 2Kcfs) to access spillway, and the tree has yet to be removed.
12/15/2015 3:00:00 AM General Site flooding (18 Kcfs) and debris strikes have caused disconnection of canbus at two sites leading to the spillway antennas. We have lost connectivity to antennas 5-15. Flow has likely disconnected the canbus on the South side wing-wall. When flow recedes to allow access to the wing-wall (~10 Kcfs), the canbus reconnection will restore antennas 9-15. The canbus has also been compromised at the north-middle pier. This has disconnected antennas 5-8. The canbus cannot be restored at this location until flow drops below 2Kcfs. All ladder antennas continue to function properly.
10/16/2015 2:34:00 PM General Site fully functional with a total of 15 pass-over antennas located immediately upstream of Lebanon Dam Spillway.
10/15/2015 12:00:00 PM SiteUp Site Up.
10/9/2015 3:12:52 PM General Registered new interrogation site LD4 - Lebanon Dam Spillway
