Hydrology and Water Quality of the Beaver Dam Wash Area, Washington County, Utah,Lincoln County, Nevada, and Mohave County, Arizona

摘要

This report defines the ground- and surface-water resources of the Beaver DamWash study area and their chemical quality. Because of the small amount of surface water in the area and because the potential for ground-water development was unknown, the emphasis of this study was on the ground-water resources. Although about 200 wells had been drilled in the lower part of the wash in Arizona, especially in and near the alluvial channel-fill deposits of Quaternary age, only about 20 wells had been drilled in the channel-fill deposits in the Utah and Nevada parts of the wash, and less than 10 wells had been drilled into the basin-fill deposits older than channel fill. The primary focus of this study was to obtain more information on ground water in the channel-fill deposits and in the basin-fill deposits older than channel fill.
