Interrogation Site Metadata

LD2 - Lebanon Dam North Ladder

Status:   Decommissioned
Site Type: Adult Fishway  |  Organization: Oregon Dept. of Fish and Wildlife
General Operational Period: Seasonally
Start Date: 4/16/2015 12:00 AM
End Date: 12/16/2018 12:00 AM

Instream detection array in the North 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 Controller and 4x Biomark IS1001-ACNs. Additional hardware includes a cell modem, grid supplied power which charges 24V battery-banks to isolate power from the Master Controller and serve as battery backup in case of a power outage. The antenna configuration consists of upstream, middle, and downstream arrays. The upstream array is a single pass-thru antenna at the ladder exit. The middle array consists of two pass-through antennas which cover every route through the #5 ladder weir. One antenna spans the upstream side of the weir and one antenna covers the auxiliary water chute. The downstream array is a single pass-thru antenna on the downstream side of the #5 weir. All antennas are low-profile ferrite-shielded pass-through antennas. Site is no longer active.

3/14/2016 12:00:00 PM General Antenna 3 operational and noise reduced on 2 and 4
3/8/2016 12:00:00 PM General Antenna 2 and 4 back on line with some noise but antenna 3 still down
3/5/2016 12:00:00 PM General Antenna 2-4 down
2/27/2016 12:00:00 PM General Antenna #3 down and high interference on 2 and 4.
2/13/2016 12:00:00 PM General High noise on antenna #4 from 2/4/2016 to 2/12/2016, and completely down on 12/12/2016. Antenna #4 back up and fully operational today.
1/19/2016 6:40:00 PM SiteUp Site Up. Communication restored for Antennas 1-4. Fully Functional Site.
12/29/2015 3:00:00 AM SiteDown Site Down. Master Controller won't power-up. Will assess damage on site visit week of 1/4/2016. Likely cause is severed canbus cable causing short (therefore MC is automatically disabled). Short in canbus cable likely due to damage sustained by 4 ft diameter log that removed two pier ACN's (for LD4), and severed cable. Log still wedged on spillway, and can't be removed by adjusting gates. City of Albany will have to manually remove log when flows subside.
10/27/2015 12:00:00 PM General System down today only
10/22/2015 12:00:00 PM General Antenna #4 down today only

10/15/2015 2:34:00 PM General Intermittent operation of antenna 4 on small weir outlet. Suspect bad CANBUS connection. Will fix on next outing.
