Book Description
Excerpt from Hydrogeology of the Devil's Hole Area, Ash Meadows, Nevada The ground-water discharging from the major springs in Ash Meadows and the water level of the pool in Devil's Hole is an inherent part of a regional carbonate ground-water flow system. Ground-water movement and the location of the major Springs is controlled in part by major faults. Water from the carbonate aquifer recharges most if not all of the over lying alluvial aquifers. Large scale ground-water withdrawal by pumping from wells was initiated by Spring Meadows, Inc. In the spring of 1969. These wells draw water from the alluvial aquifers, which are highly transmissive in the Devil's Hole area. It is possible that some wells may penetrate the carbonate rock and may draw water directly from it. The relationship of the time of maximum pumping to the periods of water-level decline in Devil's Hole shows a high degree of correlation Continued heavy ground-water withdrawal by pumping will cause a continued decline in pool level in Devil's Hole and a reduction of discharge from the major springs in the Ash Meadows area. A hydrologic alternative for irrigation is to utilize the natural spring discharge in conjunction with surface storage facilities. It is estimated that the annual acre-feet discharge from springs will irrigate somewhat more than acres of land. Additional ground-water development by pumping may be possible without materially interfering with the pool level of Devil's Hole or natural spring discharge, but this effect should be determined by additional hydrologic study. A hydrologic monitoring system and a series of pumping tests should be initiated immediately to determine the discharge from each of the major springs and pumping centers and to de termine aquifer characteristics. These data could be utilized to make predictive mathematical models of the local hydrologic system which would form the basis of a water management system for the Ash Meadows area.
