• Water Quality <br />Data indicate that the quality of groundwater in the bedrock is <br />poor (see Attachment B in section II.C-Hydrology) as a result <br />of the mineral constituents picked up from the strata. <br />c, Land Use <br />General land use in the area consists of domestic livestock grazing <br />and wildlife use. Sheep have been the traditional livestock using <br />the range, however use is made by deer during hard winters. No <br />intensive agricultural activities exist on or adjacent to the mine <br />permit area within the Red Wash drainage. Field investigations have <br />not identified signs of any historic intensive agricultural activities <br />• in this area. <br />d, Vegetation <br />The dominant vegetative type found on the Red Wash alluvium is the <br />big sagebrush-greasewood community (see Map 129). Species found <br />in this type are big sagebrush (typical of moderately deep to <br />deep soils); shadacale ( a xerophytic species tolerant of alkaline <br />soil conditins), rabbit brush (common to sandy soils), and grease- <br />wood (characteristic of heavier soils with high alkali concentrations) <br />(ERO Associates, 1981). <br />Production in 1980 from the big sagebrush-greasewood community as <br />sampled by ERO Associates was 268 Kg/Ha. This is moderate in terms <br />• of the general area. <br />4/81 II.D-12 <br />
