EVENT LOG FOR SITE SWT The first line of each entry contains a date/time stamp & who is reporting. The most recent entry is listed first. Date Time Who ---------- ----- -------- 12/07/2012 14:52 Anthony Power was periodically lost between 12:52:41 on 10/30/2012 and 13:51:47 on 11/01/2012 due to a short in the fan wiring. While training different staff to take over downloading of the station buffer active was turned off on 11/6/2012 around 15:00. Buffer active was not turned back on until 11/16/2012 around 14:00. New download staff was unfamiliar with specific settings and at this time turned unique to on instead of delay. Unique delay was turned back on 11/21/2012 around 15:00. Station was not recording tag detections between 15:00 on 11/06/2012 and 14:00 on 11/16/2012. Station was not recording test tags or multiple passes of fish from 14:00 on 11/16/2012 until 15:00 on 11/21/2012. Antenna 3 had low current levels after power outage. Re-tuning did not fix. Antenna cable was eventually thought to be bad. Cable was removed on 11/29/2012 for repairs and replaced on 12/07/2012. Low read efficiencies were expected between 11/01 and 11/29 with no detection capability for antenna 3 between 11/29 and 12/07/2012. New cable did not increase the current. Antenna is currently running and picking up tags, but has a low read range. 10/08/2012 18:29 Rick Power was lost to the MUX on October 5, 2012 at 3:58:54. We restored power to the MUX on October 5, 2012 at 11:12:43. Complete data loss occurred during the power outage. 09/21/2012 08:48 Rick Operations normal. Low flows and no equipment issues since last entry. Expect high detection efficiencies. 08/16/2012 09:19 Rick Operations normal. Low flows and no equipment issues since last entry. Expect high detection efficiencies. 05/25/2012 12:19 Rick Regarding the last event log entry on May 23, we managed to retrieve some additional data. The period of data loss now began on May 10, 2012 at 02:52:47 (as opposed to May 7 at 03:52:19). We have restored power and functionality at the interrogation site beginning May 24, 2012 at 12:38:42. Therefore, complete DATA LOSS occurred from May 10, 2012 at 02:52:47 to May 24, 2012 at 12:38:42. The site is currently fully operational. 05/23/2012 10:27 Rick On May 7 at 3:52:19 we lost power to the MUX and hardware was damaged. We are currently restoring power and functionality to the interrogation site, but it remains off line. 05/23/2012 10:05 Rick Flows have steadily declined since April 28. They are approaching base flow levels. We expect near optimal detection efficiencies since April 28. We will note any periods of substantially increased flows, but it appears that flows will remain low enough throughout the remainder of spring/summer to maintain optimal detection efficiencies. 05/04/2012 13:41 Rick Around midnight on April 27, flows at the mouth of the watershed increased to around 500 cfs (USGS gauge on Lapwai Creek). They declined back down to between 200 and 300 cfs by the end of the day. We expect some reductions in detection efficiency during this period, as the read range of the antennas may not have extended to the top of the water column. Since April 28 flows have remained between 200 and 300 cfs. We expect good detection efficiencies during this period as the read range likely extended to the surface of the water. 04/18/2012 14:27 Rick Flows at the mouth of the watershed (USGS gauging station on Lapwai Creek) dropped from over 600 cfs on April 2 to around 400 cfs on April 4. Detection ranges likely did not reach the surface of the water during this period, thus considerable reductions in detection efficiency may have occurred. Since April 4, flows at the mouth have remained between 400 and 200 cfs. Some reductions in detection efficiency during this period are possible due to fast moving water and inadequate antenna coverage on the stream margins, but detection ranges likely reached the surface of the water. 04/02/2012 16:23 Rick On March 26 flows at the mouth of the watershed (USGS gauging station on Lapwai Creek) rapidly increased to over 2500 cfs. Flows remained over 1000 cfs until the early morning hours of March 27. We expect considerable reductions in detection efficiency during this period. Since March 27 flows have fluctuated between 500 and 1000 cfs. We expect considerable reductions in detection efficiency during this ongoing period as well. 03/20/2012 06:09 Rick Throughout the morning hours of March 16, flows at the mouth of the watershed (USGS gauging station at the mouth of Lapwai Creek) increased to over 800 cfs. Since the peak on March 16, flows have been steadily declining and are currently around 200 cfs. We expect that reductions in detection efficiency occurred during this period of high flows. If flows continue to decline, we expect detection efficiencies will soon return to near optimal levels. 03/12/2012 08:45 Rick Flows at the watershed mouth (USGS gauging station on Lapwai Creek) have remained between 100 and 200 cfs since March 9. Slight declines in detection efficiency may be occurring due to increased flows, but read ranges likely extend to at or near the water surface. 03/07/2012 10:25 Rick On March 5 at around 12:00am flows at the mouth of the watershed (USGS gauging station on Lapwai Creek) peaked at over 200 cfs. Flows stayed above 100 cfs until mid-morning on March 7. Possible reductions in detection efficiency during this period, but read ranges were probably at or near the water surface throughout these increased flows. Flows are currently decreasing below 100 cfs but we will report if they start to increase again. 02/29/2012 09:50 Rick Flows at the USGS gauging station at the mouth of the watershed (Lapwai Creek station) rapidly increased to over 600 cfs in the early morning hours of February 22. We expect detection efficiencies were reduced during this surge in flow. By February 26 flows receded to around 100 cfs and we expect detection efficiencies are now back to their optimal levels. 01/31/2012 15:47 Rick Continued low flows have likely resulted in high detection efficiencies. Operations normal. 01/23/2012 10:21 Rick Operations normal. Data collection has been uninterrupted since antennas were turned back on November 2, 2011. Discharges this winter have remained relatively low and we expect no periods of reduced read efficiency due to high flows. 01/01/2012 00:00 PTOC_Bot Annual log file initiation for SWT #### End of Event Log for SWT ###
