In <br />addition, provisional streamflow data from the USGS for the Huerfa~ao River neax Boone, the <br />Apishapa River neaz Fowler, and the Purgatoire near Las Animas are included in Appendix A. <br />The data provides the mean streamflow for each day. T1xe relatively high mean streamflow on <br />Fountain Creek indicates the flood produced a high volume causing the abnormally high levels <br />of streambank erosion along the creek. <br />Table 3-1 shows staff gauge data taken from La Junta and Las Animas. The data shows the <br />movement of the crest. Table 3-2 shows estimated peak flows on the Purgatoire F~iver at <br />Trinidad (Corps of Engineers gage), Thatcher (USGS gage), and belo~v Trinidad Dam. No <br />releases were made from Trinidad Dam during the event. <br />TABLE 3-1 <br />STAFF GAUGE DATA FROM ARKANSAS RNER A.T <br />LA JUNTA AND Y,AS ANIMAS <br />Location Date-Time <br />La Junta 1 May 99 @ 1400 hrs <br />2 May 99 @ 0900 hrs <br />2 May 99 @ 1100 hrs <br />3 May 99 @ 1100 hrs <br />4 May 99 @ 1100 hrs <br />5 May 99 @ 1100 hrs <br />6 May 99 @ 1100 hrs <br />Staff Gauge <br />12.25 <br />1514 (peak) <br />15.04 <br />12.36 <br />(Not reporting) <br />(Not reporting) <br />(Not reporting) <br />Las Animas 1 May 99 @ 1100 hrs <br />2 May 99 @ 1100 hrs <br />2 May 99 @ 2100 hrs <br />3 May 99 @ 1100 hrs <br />4 May 99 @ 1100 hrs <br />5 May 99 @ 1100 hrs <br />6 May 99 @ 110Q hrs <br />9.50 <br />11.75 <br />13.99 (peak) <br />12.59 <br />10.60 <br />9.89 <br />8.97 <br />Chapter 3- Flood ofApri129, 1999 <br />Post Flood Assessment Report= 17 Draft Revised l19/09/99 <br />
