S. 23, T. 21 S, a S2 3, Artesian water General: Practically all of the- water used in Las_ Vegas Valley, excent that pumped from Lake Mead to the magnesium plant at nenderson, is obtained from artesian wells and springs. The aquifers wii PP y this confined water are beds of sand and sarid and gravel separated y confiningbeds*o£ d a y end silty clay. The water enters the aquxfers several hundred feet above the floor of the valley and is trapped b* the overlying clay beds. TiJhen wells are drilled through the confining bed. to £ e J S lS T t h e water tends to rise to the level of its surface in the upper portions of the aquifers, thus producing flowing wells at the lower elevations. On the basis of the geologic and hydrologic conditions in Las Veeas Valley, four ground-water districts have been outlined (see Figured). From north to south these districts are; (l) ine xorth Las V e S Valley District including all of the valley north of the north boundary of"Township 19 South and south of Indian Springs. covers the Owens Dry Lake area, most of the area trioutar, ^o Lee Canyo in the Soring Mountain large, and most of the area riou ax Sheen Mountain Range.
