saturated. There 'a re two hay fields in the upper _po rti.on of Sage Creek (Sections 30 and 19). {One of the fields. has the. potential for being flood irrigated. Ln._order to create • the field, it was necessary to relocate the stream channel. The channelized portion of the stream runs alongside the road and has the potential. for being used as an irrigation ditch. The other field occurs at the base of .s side tributary to Sage Creek. This field } (_is subirrigated but not flood irrigated' The third hay field is located approximately 1.5 miles downstream (Section 18 ). It occurs on valley fill material and was created in much the same way as the upstream fields. The stream was relocated along the western side of the valley so that the field occupies the central portion of the valley bottom. The field i is subirrigated and is used to produce grass hay. ~ Just downstream from the third hay field is the site of Sage Creek Reservoir. This reservoir was breached and drained in May, 1985. Currently, a, portion of the old) reservoir site supports native wetlands, is subirrigated, and is used for livestock ~grazing3 Downstream from Sage Creek Reservoir, the stream channel is deeply incised and the only areas that are subirrigated are confined to the stream channel itself. The upland areas . support native dryland shrub communities. The valley maintains this pattern until the stream leaves the mountain valley. ~/,/~ -~ . 1 ~ y The lower portion of Sage Creek is similar to Clry Creek. The only subirrigated areas are ~ ~ ~~ ~, A, those immediately within the stream channel. Most of the alluvial areas along Sage Creek L~ are used for dryland agriculture or native rangeland. There is one segment (in Section J ~p~' ~ `MJ~ 30, T6N, R88W)~of the alluvial deposits that is used for production of alfalfa hay and / ,appears to be flood irrigated with water from Sage Creek. There is very little potential for developing additional irrigation along either of the streams. The upper portions of the streams are too narrow to develop significant irrigated fields. it would be necessary to move the stream channel to- one side of the valley or the other, fill the existing channel, and smooth the existing valley deposits. Also, all of the existing dryland vegetation would need to be removed. It would not be feasible to try to develop hay fields on the existing topography because access for equipment would be too difficult, especially in portions of the valley where the stream is so deeply incised. The capital expenditures for developing fields in these valleys is • probably too high to be cost effective. In the lower portions of Sage Creek and Dry J 18
