As a result of the inspection, no corrective <br />measures are planned. <br />GOAT TRAIL EXIT CHANNELS <br />Transects were measured at the three constructed exit channels along the Goat Trail. The <br />location of these outlets are shown on Exhibit 1, Sheet 2 of 2.s The channels were measured <br />across monuments placed in 1993 and compared to evaluate erosion activity. The survey results <br />are shown graphically in Appendix A. Each of the three drainage areas had cross-section <br />measurements taken at two locations. <br />Exit Channel 1 <br />The cross-sections show that this feature remained stable when compared to the 2002 <br />survey data. Cross-section 2 indicates the feature is relatively stable in this section of the channel <br />with periods of agradation and degradation. No corrective measures planned as a result of the <br />inventory. <br />Exit Channel 2 <br />Cross-section 1 shows show that this feature remained stable when compared to the 2002 <br />monitoring data. The lower section of the channel at cross-section 2 also shows this feature <br />remained stable when compared to the 2002 survey data. No corrective measures planned as a <br />result of the inventory. <br />Exit Channel 3 <br />' Cross section 1 and cross section 2 both indicate the feature remained stable when <br />compared to 2002 data. No corrective measures planned as a result of the inventory. <br />15 <br />
