There are eight livestock ponds located within the NHN permit area. The total area of the Ponds <br />vegetation type as shown on Map 2.04.10-1, is 1.03 acres and this type equals 0.32 percent of the <br />mine permit area. <br />IRRIGATION DITCH <br />This vegetation type corresponds to the Second Park Lateral Ditch which enters the site near the <br />southeastern portion of the Meehan property and exits the area on the western side of the Garvey <br />property. Given the duration and rate of flowing water, this large ditch is devoid of vegetation <br />and can more correctly be considered to be a canal. All other smaller lateral ditches on the site <br />have the water moved with sufficient regularity that they are mostly dominated by plants. <br />The total area of the Irrigation Ditch vegetation type as shown on Map 2.04.10-1, is 0.46 acres <br />and this type equals 0.14 percent of the NHN permit area. <br />DRAINAGE CHANNEL <br />This vegetation type exists in those areas where irrigation tailwaters flowing from up slope fields <br />collects in the bottoms of swales and draws to form stream channels. This designation <br />corresponds to those areas covered by the Corps regulations for sites possessing an ordinary high <br />water mark (OHWM). According to their regulations, areas possessing an OHWM possess <br />flowing waters for sufficient duration to render them devoid of vegetation either through the <br />processes of physical eradication or by flooding out the vegetation. Within the NHN permit area, <br />there are two areas, one in the bottom of Meehan Draw and the other in the bottom of the <br />unnamed draw which flows across the southeast portion of the site which possesses these <br />characteristics. <br />The total area of the Drainage Channel vegetation type as shown on Map 2.04.10-1, is 0.07 acres <br />and this type accounts for 0.22 percent of the mine permit area. <br />Section 2.04. 10 Page 27 of 36 June 2016 (TR -14) <br />
