IML - Imnaha River Weir Adult Ladder

The site is located at the Oregon Dept. of Fish and Wildlife (ODFW) fish weir on the Imnaha River. The site was initially installed with two antennas in the ladder; a third antenna was added in June 2018 to monitor all fish handled in the work room at the trap. The antennas are currently driven by Biomark IS1001s and controlled by a Biomark IS1001-MC. The equipment is powered by a Hybrid- TEG (model 5220 and 1kw solar). The readers are connected to the controller via Biomark Data-Over-Power (DOP) cabling. The MC is connected to a satellite modem for remote telemetry. The site is being remotely monitored by Biomark with automatic downloads (and PTAGIS submissions) every four hours. The power supply and remote telemetry are being shared by the three interrogation sites at the weir, IR4, IR5, and IML.

Event Logs

Event Date	Comments	User
05/18/2015 04:00 PM	The Imnaha Weir was fully installed by 13:00 hours on 5/18/2015, the adult trap was opened, and the PIT tag equipment was fully operational by 4:00 p.m.. PIT tag detections in the adult ladder have been monitored by ODFW annually since 2006. PIT tag detections from 2006-2014 were submitted to PTAGIS as unobserved recaps. Contact the data steward for more information about available PIT tag data from 2006-2014.	feldhauj
06/04/2015 04:00 PM	The lithium ion battery in the multiplexer failed on 27 May. The site was not functioning properly from 27 May to 4 June. Replaced the lithium ion battery on 4 June at 10:30 a.m. The site is functional again.	feldhauj
09/08/2015 07:00 AM	The last successful detection of the test PIT tag was on 9/8/2015 at 7:00 a.m. . The site was turned off on 9/10/15. No PIT tag data is available after 9/8/2015 at 7:00 a.m. because it appears the multiplexer experienced an equipment malfunction. IML will be offline until spring 2016.	feldhauj
03/31/2016 09:56 AM	The FS1001 multiplexer was turned on to begin monitoring the juvenile hatchery Chinook smolts exiting the acclimation pond. Volitional release of Chinook smolts from IMNAHW began on 4/1/2016.	feldhauj
04/06/2016 11:30 AM	The FS1001 multiplexer was turned off. Juvenile outmigration of smolts leaving the acclimation pond was completed because all of the smolts exited the acclimation facility.	feldhauj
05/16/2016 02:00 PM	Site is active and monitoring for PIT tags.	feldhauj
05/19/2016 01:30 AM	PIT tag equipment was non-functional from 5/19/2016 at 1:30 a.m. until 5/23/2016 at 10:55 a.m. The Imnaha Weir was not operational from 18 May through the morning of 23 May.	feldhauj
05/23/2016 10:55 AM	PIT tag equipment operational at approximately 10:55 on 23 May. The Imnaha Weir was not operational from 18 May through the morning of 23 May.	feldhauj
05/31/2016 07:00 AM	Suspected lithium battery failure. Data was lost between 5/31/16 @ 7:00 a.m. and 6/1/16 at about 10:00 a.m. Replaced lithium battery on 6/2/2016. Replaced one of the 12V backup batteries. Reprogrammed FS2001 and set the virtual tag for a 30 minute cycle.	feldhauj
06/02/2016 10:00 AM	Data was lost between 5/31/16 @ 7:00 a.m. and 6/1/2016 at about 10:00 a.m. Fixed date/time stamp on tags detected between 6/1/16 @ 10:00 am. and 6/2/2016 prior to replacing the lithium battery at 10:15 a.m. Reprogrammed FS2001 and set the virtual tag for a 30 minute cycle. Site was functioning normally by 10:45.	feldhauj
06/14/2016 05:24 PM	Replaced a power switching board, installed 4 new deep cycle batteries, and plugged the battery charger back into the AC outlet. When I arrived at the site, the battery charger was disconnected from the AC power outlet and was not able to re-charge the deep cycle battery backup. This resulted in intermittent power failure to the FS2001 multiplexer starting on 6/11/2016 and resulted in full power failure at approximately 2:40 a.m. on 6/13/2016. No PIT tag data was collected between 2:40 a.m. on 6/13/2016 until 13:30 hrs on 6/14/2016. The site was operational by 13:30 hrs on 6/14/2016.	feldhauj
08/08/2016 09:00 AM	Site is temporarily down for equipment upgrades. No data will be collected until approximately August 12th. Data uploads will be delayed another couple of weeks until the new upload procedures are finalized.	feldhauj
08/12/2016 09:00 PM	Installation of new equipment by Biomark complete. Detections from 08/12/16 21:06:07 thru 08/18/16 12:52:58 were captured during the system testing phase and obtained via buffer download; detections from 08/18/16 14:38:26 thru 09/28/16 12:39:29 were downloaded via remote comms prior to engaging automated submissions.	feldhauj
09/09/2016 12:30 PM	The Imnaha Weir was removed on 9/9/2016. The weir removal was followed by dewatering the adult ladder. The antennas are still in the ladder, but their is no water. The adult ladder will be dewatered until juvenile acclimation in March/April.	feldhauj
03/22/2017 11:11 AM	Antennas for IML were turned on.	feldhauj
03/27/2017 11:11 AM	Site visit. Antennas were dropped back into the bottom of the fish ladder.	feldhauj
03/17/2018 08:09 AM	Antennas were activated for the season.	feldhauj
04/03/2018 08:09 AM	Volitional release of Chinook smolts from the acclimation pond started. Observed a voltage drop that began on 4/3/2018 that affected these three sites: IR4, IR5, IML. All three sites are fun off the same power supply. The drop in voltage resulted in some antennas intermittently loosing power at all three sties.	feldhauj
04/08/2018 08:09 AM	Voltage problems at IR4, IR5 and IML continued to deteriorate. Sites are intermittently turning on and off.	feldhauj
04/10/2018 08:09 AM	A site visit on 4/10/18 revealed that the hybrid power system is tripping the breaker switch that controls power input from the solar panels. The thermal electric generator (TEG) is proving some power to charge the batteries. Without the solar panels, the site is not able to maintain adequate power to run all three sites simultaneously. Master controller 1, which runs IR5 was turned off to conserve power in the hopes that we could maintain some data collection from IR4 and IML to monitor the Chnook smolt releases.	feldhauj
04/16/2018 10:00 AM	IML is down. The data plan was exceeded so real time remote monitoring is on hold until further notice. On 4/16/18, we replaced the solar charge controller. This did not solve the problem where the breaker switch for the solar panels keeps getting tripped. We were able to utilize the solar panels if the thermal electric generator (TEG) was turned off. Since the smolt releases from the acclimation facility are done for 2018, we turned off master controller 2 (MC2) which runs (IR4 and IML) and turned on MC1 (IR5). IR5 should be collecting data as of 4/16/18 at 12:30 p.m.	feldhauj
04/24/2018 10:30 AM	The master controller (MC2) for IML was turned back on. Replaced a breaker switch that controlled the solar panel. Updated firmware. Propane tank at 60%.	feldhauj
06/26/2018 08:30 AM	The site was down sporadically from about out 8:30 a.m. to about 12:30 p.m. to add antenna 9 (i.e., "Work Room Antenna" )	feldhauj
07/28/2018 07:30 AM	Power outage from 7/28/18 @ 7:30 am until 7/31/18 @ 8:00 am.	feldhauj
09/14/2018 01:30 PM	The Imnaha Facility was shut down for the Chinook trapping season and the adult ladder was de-watered. The antenna to the "trap house" was turned off. Water to IML will not be turned on again until the juvenile Chinook acclimation period in March.	feldhauj
10/23/2018 01:00 PM	Installed a breaker that allows us to manually turn off A8 and A7. Therefore, we have manually turned off A7, A8, and A9. A7 and A8 will be manually turned on again in March to monitor the juvenile releases from the acclimation pond. Currently, there is no water in the adult ladder.	feldhauj
03/27/2019 04:45 PM	The antennas for IML are associated with the master controller (MC) than runs IR4. I turned on the two antennas for IML. Updated firmware on the MC to Application v1.6.4.S19 and CBG Firmware v1.6.5.	feldhauj
09/05/2019 03:50 PM	The two antennas in the adult ladder (A7 and A8) were turned off for the season about 3:50 p.m. They will be turned on again in the spring.	feldhauj
03/20/2020 11:50 AM	Turned on the master controller to operate IML. For more details, see the log event for IR4. IR4 and IML are operated by the same master controller.	feldhauj
