they are located immediately south of the facilities area and the Tie-ACrosa Haul <br />Road. The fields are too high on the landscape to be subirrigated by Dry Creek. <br />There is little potential fer developing additional irrigation along Dry Creek <br />upstream of the Loadout facility area. Based on the historical use of the area, <br />it appears that stream £low that could be diverted in the Dry Creek Ditch is not <br />sufficient to irrigate any more acreage than that currently being irrigated for <br />alfalfa production in Sections 22 and 27. <br />Downstream from the dryland agriculture fields, there are areas in Section 14 and <br />15 of native rangeland that support greasewood/rabbitbrush shrublands. Portions <br />of these shrubland areas are generally within the Loadout permit area - this is <br />the only reach of Dry Creek that traverses the permit area. The soils are quite <br />saline/alkaline and have salt deposits on the ground surface. The areas are too <br />high on the landscape and are not subirrigated. A narrow channel terrace runs <br />along the stream and appears to be subirrigated. <br />Downstream from the greasewood/rabbitbrush shrublands, the ground water is closer <br />' to the surface and the stream channel is not so deeply incised. At this point <br /> (the southeast corner of Secti on 10), there is water fl owing in the stream and it <br /> is diverted into two separate ditches (Walker Ditch No. 1 and No. 2) . The water <br /> from these ditches is used to irrigate grass hay fields just east of the Routt <br /> County Fairgrounds in Hayden. <br />The northern most portion o£ the permit area lies within the Yampa River <br />floodplain. This is a broad valley formed by Yampa River alluvial material. This <br />landscape is north of the rail spur cut and is located north o£ the Walker Ditch. <br />Land use is irrigated agriculture for grass hay and alfalfa. The area is <br />irrigated with water from the Walker Ditch. The water table appears to be high, <br />possibly due to Walker Ditch seepage, or Shelden Ditch flows, and it is possible <br />that the Fields are also subirrigated. <br />Conclusion. Lands satisfying the geomorphic and flood or subirrigation criteria <br />of alluvial valley floors do exist adjacent to Dry Creek. Most irrigated acreages <br />are located upstream o£ the permit boundary in Sections 22 and 27. There is some <br />additional irrigated land downstream in Section 10. Lands along the Dry Creek <br />corridor within the permit boundary are not irrigated - they are floodplain <br />terraces and uplantl benches that are too high on the landscape to be subirrigated, <br />and the area is to narrow without available ditch water to be flood irrigated. <br />TR-07 19-3.4 Revised 03/06 <br />
