Interrogation Site Metadata

IML - Imnaha River Weir Adult Ladder

Status: Active - Operational

Site Type: Adult Fishway | Organization: Oregon Dept. of Fish and Wildlife

General Operational Period: Seasonally
Start Date: 5/18/2015 12:00 AM

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 Date	Event Type	Comments
4/3/2024 3:00:00 PM	SiteUp	Antennas were powered on to monitor the juvenile hatchery releases.
9/7/2023 3:45:00 PM	SiteDown	The adult trap and ladder were turned off for the 2023 spring/summer Chinook trapping season on 9/7/2023. IML was turned off at about 3:45 pm. on 9/7/2023 because there is no longer water in the adult fish ladder. The site will be turned back on in late March or April 2024 when the site is adult/juvenile fish facility is utilized to acclimate and release juvenile Chinook Salmon.
6/14/2023 3:00:00 PM	SiteUp	Antennas turned on about 3:00 p.m. on June 14th.
10/30/2022 5:00:00 PM	SiteDown	Site was turned off for the winter. Will be turned back on when ladder is back in use.
4/7/2021 11:35:00 AM	SiteUp	Site powered up for 2021. All antennas appeared to be working and tuned.
10/23/2020 10:42:00 AM	SiteDown	Shut the site down for winter.
3/20/2020 11:50:00 AM	SiteUp	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.
9/5/2019 3:50:00 PM	General	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.
3/27/2019 4:45:31 PM	SiteUp	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.
10/23/2018 1:00:00 PM	General	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.
9/14/2018 1:30:00 PM	General	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.
7/28/2018 7:30:00 AM	General	Power outage from 7/28/18 @ 7:30 am until 7/31/18 @ 8:00 am.
6/26/2018 8:30:00 AM	General	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" )
4/24/2018 10:30:00 AM	SiteUp	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%.
4/16/2018 10:00:00 AM	SiteDown	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.
4/10/2018 8:09:00 AM	General	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.
4/8/2018 8:09:00 AM	General	Voltage problems at IR4, IR5 and IML continued to deteriorate. Sites are intermittently turning on and off.
4/3/2018 8:09:00 AM	General	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.
3/17/2018 8:09:00 AM	SiteUp	Antennas were activated for the season.
3/27/2017 11:11:00 AM	General	Site visit. Antennas were dropped back into the bottom of the fish ladder.
3/22/2017 11:11:00 AM	SiteUp	Antennas for IML were turned on.
9/9/2016 12:30:00 PM	SiteDown	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.
8/12/2016 9:00:00 PM	SiteUp	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.
8/8/2016 9:00:00 AM	SiteDown	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.
6/14/2016 5:24:47 PM	General	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.
