EVENT LOG FOR SITE MIS Most recent activity to be listed first. First line of each entry lists date, time and who is reporting. Subsequent lines of each entry aligned under Time column. Do not use tabs, only spaces. Date Time Who What ---------- ----- -------- ----------------------------------------------- 09/21/2012 08:57 Rick Operations normal. Low flows and no equipment issues since last entry. Expect high detection efficiencies. 08/16/2012 10:25 Rick Operations normal. Low flows and no equipment issues since last entry. Expect high detection efficiencies. 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 10:26 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 09:51 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 17:14 Rick Data collection continues uninterrupted. Continued low flows suggest high detection efficiency so far in 2012. 01/30/2012 16:12 Nicole Initial event log entry for new interrogation sites MIS and WEB.
