<br /> <br />N <br />o <br />U1 <br />00 <br /> <br />Figure 2.4. Price River Valley estimated annual water budget in acre-feet/year. (Taken from <br />Utah Division of Water Resources 1975). <br /> <br />Groundwater <br /> <br />The use of groundwater within the <br />central baain is limited by the quality of <br />the water available. Total dissolved solids <br />have ranged from 3,600 to 73,000 mg/l in <br />exploratory wells, Only the best of this <br />water is useful even for stock watering. <br /> <br />Above the central basin primarily in the <br />Colton area, groundwater is of high quality. <br />Cordova (1964) estimated that approximately <br />3,000 acre-feet per year of groundwater <br />presently were being withdrawn by pumping and <br />by outflow from springs and seeps. He also <br />estimated that an additional 4,000 acre-feet <br />per year of groundwater resources could be <br /> <br />developed. <br />groundwater <br />Valley just <br /> <br />Clyde et a1. (1981) described <br />quantity and quality in Pleasant <br />upstream from Scofield Reservoir. <br /> <br />Vegetation <br /> <br />The principal vegetative types on <br />natural or uncultivated lands in the basin <br />are Yellow Pine and Douglas Fir in the <br />headwater areas, Pinyon-Juniper on the gravel <br />caps of the lower slopes, and Shadscale- <br />Sagebrush in the valley bottoms (Mundorff <br />1972). It is from these Shadscale-Sagebrush <br />lands that the vast majority of the salt <br />pickup by overland and microchannel flow <br />occurs. <br /> <br />15 <br /> <br />
