This wetland is located as three <br />small segments in the alluvial deposits of the steep-walled, high-gradient drainage as indicated <br />on Map E5-1. The wetland averages 10 feet in width (five feet on either side of the thalweg <br />channel), but ranges from as narrow as 5 feet in width to 16 feet depending on intermittent <br />alluvial deposits. The three segments were documented to be 150 feet long (lowest segment), <br />141 feet long (middle segment) and 522 feet long (upper segment). The three segments are <br />broken into components by two approximately 120-foot segments of a mesic expression of <br />• upland vegetation. <br />Excepting the two central breaks, the wetland extends from UTM grid coordinates 0279483 <br />x 4311231 at the low end to 0279266 x 4311411 at the upper end. (Grid coordinates must be <br />considered approximate given that satellite reception in the bottom of the drainage was only <br />fair.) The lower end is located approximately 378 feet (along the drainage bottom) upgradient <br />from the South boundary fence that indicates the southern boundary of Bowie's permit area. <br />The two central breaks in the wetland area do not exhibit wetland conditions for one or more of <br />three principal reasons, 1) steepness of gradient, 2) narrowness of channel bottom ("V"-shaped <br />drainage), and/or 3) deeply incised water course. <br />One US Army Corps of Engineers style sample point was established approximately 400 feet <br />below the upper end of the uppermost wetland segment. The soil matrix to a depth of 12 inches <br />was colored 10 YR 3/2 and exhibited moderately abundant and bright mottles at a color of 10 YR <br />5/6 in the lower 6 inches. Soils were saturated to the surface at the time of evaluation (May 24, <br />2006) and the drainage exhibited modestly flowing water (1 - 2 gallons per minute). Vegetation <br />in the wetland areas was dominated by Canada thistle (Cirsium arvense), Baltic rush (Juncus <br />balticus), and clustered field sedge (Carex praegracilis), along with occasional subdominants such <br />as Kentucky bluegrass (Poa pratensis).
