Summary:
Precipitation totals of 245 and 210 mm were measured at UE-29 UZN {number_sign}91 and UE-29 UZN {number_sign}92 respectively, during the 1992 water year, October 1, 1991 to September 30, 1992. Approximately ninety percent of the precipitation fell during the period December 27 to April 2. Localized streamflow was generated in the Fortymile Wash drainage basin during the February 12-15, 1992 and March 31, 1992 precipitation, and infiltrated into the streambed materials. The streamflow went across the UE-29 UZN {number_sign}91 neutron-access borehole location and within several meters of the UE-29 UZN {number_sign}92 location. Neutron logging in these boreholes showed increases in the volumetric water content of the unsaturated alluvium and indicated streamflow infiltrated to a depth of approximately 5 meters. The volumetric water content in the upper 5 meters then gradually decreased during the remaining part of the water year. Ground-water levels rose over one meter in wells UE-29 a{number_sign}1 and UE-29 a{number_sign}2, and one-half meter in neutron-access borehole LJE-29 UZN {number_sign}91 following the streamflows. Water level declines of 0.5 meter in UE-29 a{number_sign}1 and rises of 0.2 meter in UE-29 a{number_sign}2 and 0.1 meter in UE-29 UZN {number_sign}91 coincided with a June 29, 1992 earthquake at the Little Skull Mountain, located approximately 27 kilometers southeast of the wells.
