4/14/2021 3:07:00 PM SiteUp The site is up and running.
6/15/2020 11:30:00 AM SiteDown Camp Creek array site was removed from the current location. Looking to install upstream on TNC property.
2/7/2020 3:10:00 PM General From 11:31 on November 20, 2019 to 15:10 on February 7, 2020 the site has operated normally and with no interruptions.
11/19/2019 5:52:00 PM SiteUp The site began operating again when antennas 3 and 4 were installed and began operating at 17:52 on November 19, 2019. Antenna 2 was reinstalled and began operating and detecting test tags at 10:45 on November 20, 2019. Antenna 1 was reinstalled and began operating and detecting test tags at 11:31 on November 20, 2019.
11/19/2019 10:03:00 AM SiteDown Antenna 1 was shut off at 10:03 on November 19, 2019. The site was not operating from 10:03 November 19, 2019 until antennas 3 and 4 were installed and operating at 17:52 on November 19, 2019.
9/6/2019 5:03:00 PM General Antenna 3 failed after 17:03 on September 6, 2019. The site continued to operate with only antenna 1 functioning until the site was repaired. Repairs began on November 19, 2019.
4/9/2019 5:00:00 AM General Due to a high water event two antennas, two and four were lost at CMP. Number four went out first between 4:53 and 5:03 on April 9, 2019 and antenna 2 went out soon after that between 5:23 and 5:33. From that point CMP operated with antennas 1 and 3 functioning until 17:03 on September 6, 2019.
2/12/2019 5:30:22 PM General The CMP site ran uninterrupted and functioned normally from the previous event log on March 6, 2018 until January 1, 2019. Due to a power supply issue the site was intermittently down between January 1, 2019 at 0:25 and January 10 2019 at 21:16. No data was collected between January 10 at 21:16 and February 6, 2019 at 11:13. The power supply issue was resolved and the site has been running uninterrupted and functioning normally from February 6, 2019 at 11:13 to present.
3/6/2018 2:29:13 PM General The CMP site has been running uninterrupted and functioning normally from the previous event log at 11:12:00 AM on March 17, 2015 to the present.
3/17/2015 11:12:00 AM General The CMP site has been running uninterrupted and functioning normally from approximately 10:00 on September 25, 2014 to the present.
9/26/2014 4:32:31 PM SiteDown On August 19, 2014 it was discovered that C4 experienced a sudden drop in current around 17:40 on July 24th.  Due to this loss of current, hourly test tags fired from the Multiplexing Transceiver System were not being detected by C4.  On September 25, 2014 at approximately 10:00, the antenna cable was replaced on C4 enabling it to function normally.   
3/27/2014 2:34:47 PM General On March 14, 2014, following a series of high flow events between February 28th and March 7th, antenna #3 (C3) was found dislodged from the substrate and hanging by a single strap in stream, oriented parallel to stream flow with the antenna cable still connected. DRS records downloaded from the Multiplexing Transeiver System indicated that the current to C3 reached zero at approximately 22:40 on March 9th. Prior to this time, although exact dislodge date and time is unknown, the antenna was to some extent functional, as it successfully detected a tag on March 7th at 22:43. On March 24, 2014 around 12:00, the damaged antenna (C3) was removed and a new antenna was installed, secured, and became operational.
12/17/2013 12:57:32 PM General The multiplexing transceiver system malfunctioned, on June 15, 2013, resulting in no test tag storage after 21:11. A buffer download was conducted on the transceiver on June 24, 2013. The transceiver was reset and the normal test tag scanning/storing schedule was resumed at 14:38 on June 24, 2013. No new unique tag detections occurred during this downtime. On November 2, 2013 at approximately 05:00, the multiplexer transceiver power supply was interrupted. This problem was discovered on November 12, 2013, and resolved by replacing the switcher relays on November 18, 2013. The site has been running, uninterrupted from 11:40 on November 18, 2013 until the present.
12/6/2013 1:33:59 PM General Registered new interrogation site CMP in PTAGIS.
2/15/2013 12:14:00 PM General CMP became operational and began collecting data on February 15, 2013, at 12:14.
