Geohydrology of monitoring wells drilled in Oasis Valley near Beatty, Nye County, Nevada, 1997
- USGS
Twelve monitoring wells were installed in 1997 at seven sites in and near Oasis Valley, Nevada. The wells, ranging in depth from 65 to 642 feet, were installed to measure water levels and to collect water-quality samples. Well-construction data and geologic and geophysical logs are presented in this report. Seven geologic units were identified and described from samples collected during the drilling: (1) Ammonia Tanks Tuff; (2) Tuff of Cutoff Road; (3) tuffs, not formally named but informally referred to in this report as the "tuff of Oasis Valley"; (4) lavas informally named the "rhyolitic lavas of Colson Pond"; (5) Teritary colluvial and alluvial gravelly deposits; (6) Tertiary and Quaternary colluvium; and (7) Quaternary alluvium. Water levels in the wells were measured in October 1997 and February 1998 and ranged from about 18 to 350 feet below land surface. Transmissive zones in one of the boreholes penetrating volcanic rock were identified using flowmeter data. Zones with the highest transmissitviy are at depths of about 205 feet in the "rhyolitic lavas of Colson Pond" and 340 feet within the "tuff of Oasis Valley."
