SC2 - Lower SF Clearwater R at rkm 2
Status: Active - OperationalGeneral Operational Period: Year Round
Start Date: 9/19/2011 12:00 AM
Instream detection system consisting of a tandem array located in the lower South Fork Clearwater River. The array (SC2) located at river km 2 (N 46.12749 W -115.97730) consists of a single array of six 20 ft Biomark flat panel antennas each. The array spans approximately 80% of the channel during low flow conditions. SC2 is operated by the Integrated Status and Effectiveness Monitoring Project (ISEMP) cooperators Nez Perce Tribe and Biomark and was installed for continuous monitoring on September 19, 2011. 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 grid power and remote communication provided by a cellular modem.

| 4/8/2024 8:51:00 AM | General |
MUX transceiver was replaced due to a glitch in the onsite MUX causing a Standby like issue that was experienced 3 times between late March and April 3. Site was down March 19-21. Again late March 21 through March 22. An attempted repair was performed on the MUX March 22 by adjusting exciter voltage from 14.75 V to 14.70 V. Site MUX glitched again thus falling into Standby status on April 3. MUX was reset on April 4 and operated continuously through April 8 when MUX was replaced. |
| 3/21/2024 8:00:00 AM | SiteUp |
March 21, 2024 the MUX was reset. SC2 resumed normal operations and is collecting data. |
| 3/19/2024 10:00:00 PM | SiteDown |
March 19, 2024 the MUX froze up and stopped collecting data. |
| 8/1/2023 12:00:00 AM | GMC |
Site received zip ties on antenna cables where needed. SC2 is operating continuously without disruption through August 8, 2023. |
| 5/15/2023 9:20:00 AM | SiteUp |

SC2 is operating continuously without disruption through October 21, 2018. |
| 7/26/2018 7:31:00 AM | General | South Fork Clearwater 2 (SC2) antenna A2 experienced a significant drop in current in early December 2017. A2 was replaced with a Biomark 20 ft. PVC antenna on 7/26/18. SC2 is operating continuously without disruption through 7/26/2018. |
| 1/23/2018 2:29:00 PM | General | South Fork Clearwater array (SC2) had a faulty PS100 battery replaced that was causing the data logger to brown out. Lost PIT tag detection data was recovered from the MUX tranceiver buffer. SC2 is running continuously without disruption through 1/29/18. |
| 11/16/2016 9:08:00 AM | General | South Fork Clearwater 2 array (SC2) cellular mode seized to function on 10/22/16. SC2 functioning and operational without disruption through 11/16/16. |
| 1/13/2016 11:47:50 AM | General | The site is functioning and operating without disruption through January 13, 2016 |
