Table DS-1. (Continued) Descriptions of wetlands on the D & S Mining Properties. Refer to <br />Table DS-2 for lists of s ecies observed in these wetland areas. <br />Wetland <br />Location Photo <br />Number(s) Descri lions and Comments <br />P <br />Jurisdictional Status <br /> These wetlands occur in an irrigation ditch that <br /> is located on the west and north side of the site <br /> and occasionally carries water from the MFM <br />Along irrigation Farms property. A small amount of standing Non-jurisdictional- <br />ditch DS-8 water was noted in a portion of the ditch. Ditch excavated in <br />(W-DS6) Mostly the ditch is very well-vegetated with upland area. <br /> reed canary grass occurring as the dominant <br /> .species. Hydrophytic species accounted for 59 <br /> ercent of the observed s ecies, <br /> These wetlands occur along the saturated ditch <br /> margins and low areas along the irrigation <br /> ditch on the west side of the property. Water <br /> in the ditch is diverted from Big Dry Creek, just Non-jurisdicfional- <br /> upstream from its confluence with the South Ditch excavated in <br />Along irrigation Platte River. A marsh has developed in the low upland area. <br /> <br />ditch DS-9 and area along the west side of the ditch. There <br />Hydrology <br /> <br />~ C7) DS-10 were 2-3 inches of standing water th the lowest <br />dependent on water <br /> part of this area. Major species include reed <br />' diverted from Big <br /> canary grass, common cattail, chairmaker <br />s Dry Creek <br /> rush, Baltic rush and common spikerush <br /> (Eleocharis macrostachya). Hydrophytic species <br /> accounted for 75 percent of the observed <br /> s ecies. <br /> This is a small segment of excavated ditch that <br /> apparently is used to carry irrigation return <br />Along small flows from adjacent field. Soils were saturated Non-jurisdictional <br />irrigation ditch DS-11 at the surface, but there was no standing water Isolated- not <br />(W-DSS) in the ditch. Major species include reed canary connected with <br /> grass and species of knotweed. Hydrophytic existing drainages <br /> species accounted for 67 percent of the <br /> observed s ecies. <br /> This wetland occurs east of the irrigation ditch <br /> and extends eastwazd onto the adjacent <br /> property. This fs the largest wetland <br /> (approximately 25 acres) encountered on any <br /> of the properties included in the study. The <br /> source of water appears to be surface run-off as <br /> well as groundwater. The area is a closed basin Non-jurisdictional <br />(W-DS9) DS-12 and and does not drain. Soils are fine-grained and Isolated- not <br /> DS-13 somewhat saline. The northern porfion of the connected with <br /> area had standing water throughout the 2004 existing drainages <br /> growing season. Soils were saturated at the <br /> surface throughout most of the area. Major <br /> species include chaumaker's rush, inland <br /> saltgrass, foxtail barley and Baltic rush. <br /> Hydrophytic species accounted for 71 percent <br /> of the observed s ies. <br />-49- <br />
