Page 7 <br />and the side walls are virtually unchanged from last years survey. <br />Rock armoring at the bottom of the channel varies in size from 1 to <br />6 inches in diameter. A small amount of vegetation, thinner than <br />the upper reaches, exists on the sides of the main channel. The <br />area in the vicinity of this cross section appears stable when <br />compared to previous monitoring. This area will continue to be <br />monitored for excessive erosion. <br />Cross Section 5 This cross section is located on un-bonded land <br />and is being monitored only to predict how this area might affect <br />that of the bonded portion. In this vicinity vegetation is present <br />on some of the side slopes of the channel but none was noticed in <br />the bottom. Rock size in the channel varies from 2 to 12 inches in <br />diameter and the channel appears well armored. Comparing of the <br />cross sections from previous years shows very little difference <br />with the exception of some slight side wasting. This"area shows <br />very little change from last years survey and over this span of <br />time can be considered stable. <br />Based on the data collected from these five cross section areas and <br />a general survey of the area this concentrated flow feature does <br />not appear to be experiencing excessive erosion. For this reason <br />no mitigative measures are proposed for this concentrated flow <br />feature at this time. <br />Subarea 1 Erosion Condition Classification <br />This area is shown in the 1992 report on Exhibit 1, Sheet 2 of 2. <br />South of Shop Subarea 1 was evaluated using the methods described <br />in BLM Technical Note No. 346. The erosion condition composite <br />soil surface factor score for this site is 10.6, which places it in <br />the Stable erosion class. The tabulated results for this survey <br />are contained in Table 5. <br />Subarea 2 Erosion Condition Classification <br />This area is shown in the 1992 report on Exhibit 1, Sheet 2 of 2. <br />This area was also evaluated using the methods described in BLM <br />Technical Note No. 346. The erosion condition composite soil <br />surface factor for this site is 12.9 which places it in the Stable <br />category. This area shows an improvement from last year's results <br />probably due to the maturing of the vegetation in the reclaimed <br />area. The tabulated results for this survey are listed in Table 6. <br />Subarea 3 Erosion Condition Classification <br />Exhibit 1, Sheet 2 of 2 also shows the location of this area. The <br />procedure outlined in BLM Technical Note No. 346 was used to <br />evaluate this area. The erosion condition composite soil surface <br />4/19/94 DLH <br />
