A Microsoft Visual Basic Macro was used to separate the individual points into <br />distinct cross sections. The program that was written is given in Appendix B. <br /> <br />In addition. a meeting look place with David Barnet of BristleconeGIS in which ArcView GIS <br />data were obtained for the communities. The data included. but was not limited to. lakes. rivers. <br />streams. contours. roads. and annexations. <br /> <br />5.3 Hydrologic Analysis <br /> <br />The USGS gage station 091..U5oo on Surface Creek at Cedarectge wa'i used for all hydrologic <br />analysis. The data used for determining the IOO-year peak discharge were delermined from the <br />gage slation from the years of 1917 through 2(X)(). The total drainage area used was thirty-nine <br />square miles. which was obtained from the gage station data. The data obtained from the USGS <br /> <br />22 <br />
