<br />o <br />M <br />N <br /> <br />north. <br /> <br />They are rich in fertility and highly produ;;ti~;'~~~~e <br /> <br />part is under irrigation, although a number of small tracts of un- <br />developed land meeting the classification of number 2 is scattered <br /> <br />throughout the irrigated area. <br /> <br />In Elk Valley above the Harvey Gap Reservoir is a fairl,y large <br /> <br />body of land which is lsss than 50% under irrigation. The land is of <br /> <br />medium textured deep sUt loam soU of alluvial formation which supports, <br />where undeveloped, a large growth of sagebrush. This land was largely <br /> <br />classified number 2 due to topographical conditions. <br /> <br /> <br />The Da~ Ditch land is on a high mess. The soU is deep, light <br /> <br /> <br />sUt loam, brownish red in color, high in fertility and very productive <br /> <br />with irrigation. The land is largel,y under irrigation. The water <br /> <br />right, however, is junior to that of the Grass Valley Canal thus <br /> <br /> <br />restricting irrigation to earl,y spring and fall use. of water. <br /> <br />Draina/l;e <br /> <br />SoU and topographic conditions of the project area are inducive <br /> <br /> <br />to adequate drainage under irrigation. The soils are predominatel,y <br /> <br />medium-textured, open, permeable and underlain by pervious alluvial <br /> <br />substrata. Natural drainage channels are well established and provide <br /> <br />adequate surface drainage. <br /> <br />Minor problelDS of seepage may develop in the lower swales where <br /> <br />natural drainage is not as good and where underl,ying strata are <br /> <br />impervious to percolating water. This condition is not expected to <br /> <br />develop extensively following additional irrigation as only a very small <br /> <br />acreage of damaged land exists in the project area at the present <br /> <br />time. <br />
