IR1 - Lower Imnaha River ISA @ km 7
Status: Active - OperationalGeneral Operational Period: Year Round
Start Date: 12/3/2010 12:00 AM
In-stream detection system consisting of a single array located in the lower Imnaha River. The array (IR1) located at river km 7 (N 45.761162, W -116.750658) consists of four 20 foot Biomark flat panel antennas that span the entire river at base flow. IR1 is operated by the Integrated Status and Effectiveness Project (ISEMP) cooperators Nez Perce Tribe and Quantitative Consultants, Inc. and was installed for continuous monitoring on December 3, 2010. The array includes ISEMP standard site monitoring equipment including: air and water temperature probes, and a water pressure transducer to monitor stream level. Electrical power is provided by a solar/propane hybrid thermal electric generator and remote communication provided by a satellite modem.

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.

| 11/3/2023 12:00:00 AM | General |
IR1 is operating continuously without disruption through November 3, 2023. |
| 10/18/2022 1:00:00 PM | General |
Antenna B1 was replaced with a new Biomark 20 ft. PVC antenna. B1 started losing current May 29, 2022 but was still operational at 1.15 A and continued detecting PIT tags and virtual test tags at less than optimal performance. IR1 is operating continuously without disruption through October 20, 2022. |
| 9/21/2022 12:00:00 PM | SiteUp |
Site electronics enclosure was re-installed September 21, 2022 as the the threat of fire at IR1 subsided. IR1 is operating continuously without disruption again. |
| 9/10/2022 12:00:00 AM | SiteDown |
Site electronics enclosure was removed due to threat of burning up from the Double Creek Fire. Site is down indefinitely. |
| 5/29/2022 12:00:00 AM | SiteUp |
Antenna B1 lost 2A of current on May 29, 2022. B1 likely has a reduced read range affecting IR1 detection probability. |
| 11/2/2021 12:00:00 AM | General |

| 2/1/2018 9:45:00 AM | General | Imnaha River 1 (IR1) array had all 6 deep cell Solar batteries replaced on 2/1/18.. IR1 is functioning continuously without disruption through 2/7/18. |
| 8/31/2017 8:43:00 AM | General | Imnaha River 1 (IR1) antenna B2 was repaired by plugging the antenna cable back in and securing the cable with zip ties. Pressure transducer and additional antenna cables were secured under antennas. IR1 is running continuously without disruption through 9/5/17. |
| 5/4/2017 7:46:00 AM | General | The optical isolator between the MUX and data logger was replaced at Imnaha River 1 array (IR1) on May 4, 2017. IR1 has run continuously without disruption through 5/10/17. |
| 12/19/2016 2:24:03 PM | General | Imnaha River 1 (IR1) has operated continuously without disruption through 12/19/16 |
