• west of the lease area and flows toward Red Wash. The tendency <br />for flow to turn southward within one or two miles of the White <br />River rather than continuing toward the axis of the syncline <br />implies that the flow is slowly discharging into the White River. <br />The water table is from 50 to 200 feet under the ground surface <br />in most of the area, and hence, the only evidence of seeps is <br />where shallow, silty layers impede downward flow from an adjacent <br />drainage. In the alluvium, the water table is nearer the surface <br />due to movement of groundwater into the alluvium. <br />Aquifer Characteristics <br />All tests of the Upper Sandstone Facies resulted in very low <br />• transmissivity values (from 3.8 to 74 gpd /ft.). Measured maximum <br />drawdowns ranged from about 1.8 feet to 426 feet using pumping <br />rates ranging from 0.56 to 27.5 gpm. <br />No tests were run on the alluvium in Red Wash. However, approxi- <br />orations can be made based on the White River alluvial tests. <br />Qal-2 located at the confluence of Red Wash and White River had <br />transmissivity values of 521 and 406 gpd /f t. These values are <br />extremely low for alluvium. It is felt that clogging of the pore <br />spaces in the alluvium by fine material effectively slows any water <br />movement. Transmisslvities in other wells in the White Rivet <br />alluviam:zanged from 12.4 to'24970 gpd /f t. <br /> <br />4/81 II.D-11 <br />
