KHS - Big Bear Cr. @ Kendrick HS

Status:   Active - Non-Operational
Site Type: Instream Remote Detection System  |  Organization: Idaho Dept. of Fish and Game
General Operational Period: Year Round
Start Date: 12/1/2007 12:00 AM

This floating array interrogation system is located near the mouth of Big Bear Creek adjacent to the high school in the town of Kendrick, Idaho. The array is set up with an upper span of Bio Float antennas (01, 02, 03, 04) and a lower span of Bio Float antennas (05, 06, 07, 08). KHS was originally installed in 2007 with 6 pass over PVC antennas. The floating array configuration came online January 2015.

2015 1/29/2015 3:00 PM 6/25/2015 10:00 AM Array removed June 25 due to lack of flows.
2014 1/1/2014 12:00 AM 7/27/2014 11:25 AM Antenna 1 down March 6-15. Antenna 2 down March 9-26. Antenna 3 down March 9. Antenna 4 down March 6. End date based on Close Date of last file loaded in 2014.
2013 1/1/2013 12:00 AM 1/1/2014 12:00 AM Site down April 12-17. Site experienced intermittent power issues April 22-24. Data lost for May 21-26 due to alarms filling buffer.
2012 1/1/2012 12:00 AM 1/1/2013 12:00 AM Site down to high flow event on February 22. Reinstalled on March 6. Another flood event disabled all but one of the antennas on March 15.
2011 1/1/2011 12:00 AM 1/1/2012 12:00 AM An "epic run-off event" resulted in the loss of all six antennas on Jan 16. Antennas 1, 2, 4, and 5 were reinstalled on Feb. 9, and antennas 3 and 6 were reinstalled on Feb. 10; all six antennas were relocated approximately 25 meters downstream. A second high water event disabled all six antennas between March 10-13, with the timer tag detection occurring on antenna A4 on March 13 at 22:55. Antennas were re-installed and site became operational on April 20. Site taken offline July 22 to use the Mux for testing new antennas. Site back online September 26, with new configuration. Site lost power from October 31-November 7.
2010 1/7/2010 8:00 AM 1/1/2011 12:00 AM Following an extended outage in Nov.-Dec. 2009, normal operations were restored on Jan. 7, 2010. The site was out of service from March 31 - April 3 due to an unknown issue. An outage occurred from Sept. 6-8 due to a flipped GFI switch. There was an 18-hour interruption in data collection on Sept. 22-23 due to a loss of power.
2009 1/1/2009 12:00 AM 11/11/2009 12:00 PM On Jan. 13, antenna A5 was lost and antennas A3 and A6 were disconnected due to high flows. On Jan. 30, A5 was replaced, and A3 and A6 were reconnected. There are no data available Feb. 4-9 due to a communications error. The system was disabled between March 2 and May 19 due to a variety of issues. The site shut down on 6/6/09 @ ~1745 for unexplained reasons. The site was turned back on manually @ 1015 6/11/09. There are no detection data for the interval 6/19-6/25. The site was shut down between 7/27 and 7/30 to affect site repairs; detection activities did not resume until 8/17. There are no data available for ~72 hours between 11/06 and 11/09 due to improper antenna sequencing. Detection activity was sporadic at best after Nov. 11, 2009.
2008 1/1/2008 12:00 AM 1/1/2009 12:00 AM Contact Brett Bowersox ( or Ethan Crawford ( for information regarding this site. Various component failures led to a complete loss of detection data between March 13 and April 24. Detection activities were suspended on April 30, and resumed on September 19.
2007 12/1/2007 12:00 AM 1/1/2008 12:00 AM First year of operation.

1/29/2015 3:00:00 PM SiteUp Array installed.
4/7/2014 1:00:00 PM General Substantial runoff caused damage to Antennas 1 and 4 as well as electrical cables. 3-6-2014 Antenna 4 offline at 0100 & Antenna 1 offline at 2000. 3-9-2014 Antenna 3 offline at 0800 and antenna 2 offline at 1900. Flows hindered repair and replacement. Antenna 1 online 3-15-2014 1306. Antenna 2 online 3-26-2014 1620.
2/18/2014 9:46:00 AM General Operations normal. Warm rain event caused sudden rise in flows, 4000 cfs on the mainstem gauge. Antennas appear to have held.
1/30/2014 11:23:00 AM General Operations normal. Antennas 1,2,5, and 6 partially covered with shallow layer of fine sediment after minor bump in flows. Uncovered antennas and filled in any scoured out locations. Experimenting with sandbags versus natural stream bottom cobble to reduce scouring.
1/8/2014 8:34:09 AM General Operations normal. Tuning of antennas was completed on 1/2/2014 to address high noise levels. Successful tune completed. Minimal flow over antennas.
