Page 6 <br />divided in the same manner as in previous surveys for consistency. <br />The concentrated flow feature referenced in the 1992 report was <br />also measured. <br />Concentrated Flow Feature No. 1 <br />The location of Concentrated Flow Feature No. 1 is shown in the <br />1992 report on Exhibit 1, Sheet 2 of 2. The cross sections <br />measured are detailed in the 1992 report on Exhibit 2. The feature <br />appears to be reasonably stable with rock armoring present at the <br />base. The 5 cross sections measured in previous reports were <br />measured again and the results are listed below. Graphical <br />representation of these measurements are found in Figure 1. <br />Cross Section 1 In the area of this cross section vegetation is <br />established on the sides and on the bottom of the channel. Rock <br />cobble on the bottom varies in size from 1" to 4" in diameter. A <br />profile of the area is in Figure 1. Plotted data shows some <br />agradation of the channel and a lessening of one of the side <br />slopes. Current conditions at this site show little possibility of <br />future excessive erosion. <br />Cross Section 2 This area shows vegetation on the side slopes and <br />on the bottom of the channel. Rock in the channel varies from 1 to <br />5 inches in diameter. Side slopes are shown in Cross Section 2 of <br />Figure 1. Very little change is noted in the profile of this cross <br />section from last year to this year. This cross section area <br />appears stable. <br />Cross Section 3 In the vicinity of this cross section vegetation <br />is established on the side slopes and some lesser amount exists at <br />the bottom of the channel. Rock fragments in the channel bottom <br />vary from 1 to 9 inches in diameter and is providing good armoring. <br />Some pebbles existed at the bottom of the channel from what would <br />appear to be recent deposition. Comparing the graph on the cross <br />section of this area shows that the northern bank has a decreased <br />slope compared to past measurements. The lessened slope would lead <br />to the conclusion that active cutting to make the channel steeper <br />and deeper is not occurring. In fact the cross section shows <br />slightly less depth and a flatter bottom than previous <br />measurements. This cross section appears stable. <br />Cross Section 4 This area is noticeably steeper than the channel <br />above. This area is on the lower edge of the bonded strip. Flow <br />in the channel appears to be concentrating into a single channel <br />instead of braiding as noted in previous reports. Cross Section 4 <br />of Figure 1 shows agradation in the northern channel and in fact <br />this area showed considerable vegetation. The main channel shows <br />no increase in depth of the channel from the initial 1992 report <br />4/19/94 DLB <br />
