ACB - Asotin Cr. at Cloverland Brdg.

An instream interrogation site in the mainstem of Asotin Creek above the George Creek confluence, underneath the Cloverland Bridge. Site started operations in 2009 with a single row of 5 antennas spanning the width of the creek. The first two years of data were originally reported as Passive Recaptures. The site was officially registered as an interrogation site in PTAGIS December 2010. The site was damaged during high flows in the spring of 2017 and was reconfigured in September 2017 with 3 antennas in a single row. In December 2017, the original passive recapture records were removed and the detection records were submitted as interrogation data.

11/11/2013 08:29 AM	Site visited and buffer downloaded. Site functioning normally.	snbennett
01/08/2014 08:29 AM	Site visited and buffer downloaded. Antenna 4 is broken, antenna 5 has moved downstream but is still reading, antenna 3 not reading. Appears site damaged by ice sometime between December 3 and 13th based on flow gauge data.	snbennett
01/24/2014 08:17 AM	As of 12/10/2013, antennas # 3 and 4 are not reading Antenna #4 is completely broken and antenna #3 is unplugged.	crawford
02/13/2014 09:34 AM	As of 1/30/2014 site is completely operational. Antenna 4 is not longer in place, and the total number of antennas is down to 4 instead of 5 previously. Antenna sequence is as follows,1,2,3,5. All antennas have been tuned and are functional.	crawford
03/20/2017 08:10 AM	Site visited for damage assessment from current high water/flood event occurring in Asotin Creek. All 4 antennas present, high noise on antennas 1 and 2 could indicate that they are buried. Further assessment will occur as conditions allow.	jjwilson208
04/02/2017 02:53 PM	Site visited for further damage assessment as high water in Asotin Creek is receding. Antennas 1 and 2 are present but are dry and encased in a gravel bar that has formed within the North side of the creek channel at the site. Antennas 3 and 5 are not present at the MUX but are visible and do not appear to have moved but have simply come unplugged during the high water event. The water is still too high and swift to get out and plug antennas 3 and 5 back in. Further assessment will continue as Asotin Creek water levels further recede.	jjwilson208
05/31/2017 02:27 PM	Site visited for damage and repair/replacement assessment. Antennas 1 & 2 are still dry and buried under 0.5m of river cobbles but are both present and operating normally. Antennas 3 & 5 were not present at the MUX upon arrival at the site. After inspection it appeared the plug connections on both antennas had come loose during one of the many high water events Asotin Creek has experienced in late March and early April. Antenna 3 was plugged in, tuned and tested and is now back operating normally. Antenna 5 was plugged in but is not functional. Antenna 5 has shifted slightly and doesn't appear to be anchored along it's downstream and may have sustained damage as it sits directly within the thalweg at the site. Further damage assessment and removal and replacement of Antenna 5 will occur as water conditions allow. MUX Buffer was downloaded before leaving the site.	jjwilson208
07/13/2017 01:22 PM	Site is down and in the process of being rebuilt/reinstalled. All damaged antennas and cables have been removed from the site. The 2 working antennae at the site have been unburied and replacements for the 2 damaged antennae have been acquired along with replacement cables and will be installed in the next couple of weeks.	jjwilson208
09/15/2017 12:50 PM	Replacement antennas installed at site. The new configuration only employs only 3 antennas due to the significant geomorphic change that occurred at the site during the spring of 2017 and the likelihood that the site will experience significant geomorphic change again in the spring of 2018. All antennas tuned and tested, site operating normally.	jjwilson208
