July 1993 -26- 923-2515 • <br />sodium salt content, the very low pernreability, medium runoff, and steepness of slopes in some <br />localities. <br />The Cryoborolls-Rock outcrop complex is not irrigable due to the very steep slopes and the <br />Dunckley-Skyway complex, as discussed in Section 5.1.5, is not irrigable. <br />Water Availability and Quality: There are no data on the volume and quality of water <br />available for flood irrigation in Unnamed Draw, an ephemeral stream. However, this stream <br />has a smaller basin and a smaller volume of flow than Grassy Creek which does not have an <br />adequate flow for flood irrigation during the summer. There is not a sufficient volume of water <br />generated by the stream basin for flood irrigation and there may not be sufficient water for an <br />impoundment. As with Grassy Creek, it is not cost effective to build a reservoir. Additionally, <br />if the water quality of Unnamed Draw is similaz to the water in Grassy Creek, it may be only <br />mazginally suitable for growing crops. <br />Summary: There are no areas immediately along Unnamed Draw with flood irrigable soils. <br />Additionally, there does not appear to be an adequate volume of stream flow for irrigation or <br />even for the construction of a reservoir to impound water for irrigation. Finally, the quality of <br />the water for irrigation of pasture and hay grasses is probably marginal. <br />5.2.6 Wetlands <br />Wetlands occur around and upstream of Nofstger Reservoir and all along the stream channel <br />(Figure 2). These wetlands are similaz to those described in Section 5.1.6 for Grassy Creek. <br />These wetlands are not managed differently from the surrounding native rangeland. They have <br />not been seeded or enhanced with cultivazs and are not cropped, for hay. They are not <br />recognized as a special unit. <br />C~ <br />Golder Associates <br />
