LD4 - Lebanon Dam Spillway

Status:   Active - Operational
Site Type: Juvenile Fish Bypass Facility  |  Organization: Biomark
General Operational Period: Year Round
Start Date: 10/2/2015 12:00 AM

Array is a single line of antennas attached to the spillway wall spanning the entire length of the Lebanon Dam on the South Santiam River, a tributary of the Willamette River. All antennas are pass-over HDPE pipe antennas mounted on aluminum plates on the spillway face below the Obermeyer weir and covered with a FRP cover plate. The site is monitored by three Biomark Master Controllers, each connected to ten IS1001 readers. The site is powered by AC power. Data is collected with a cell modem. The site was originally operated by ODFW from 2015-2018 and was reinstalled in 2022.

Operational History

Operational history describes the period the site was interrogating for PIT tags. The comments provide anecdotal information about the operation of the site during this period. Site operational periods are updated typically at the end of the calendar year.

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.

MC 40 has been powered off due to cable damaged received from recent high flows. This only involves antennas 41- 4A on the North Spillway.
10/4/2022 4:00:00 PM SiteUp

Site operational as of 10/04/2022 @ 1600PST.
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.
