Ground-water data for the Riley and Andrews Resource Areas, southeastern Oregon

Appraisals of the resources of selected management areas in eastern Oregon are being made by the U.S. Bureau of Land Mangement. To provide needed hydrologic information, the Bureau of Land Management requested the U.S. Geological Survey to inventory ground-water data for the Riley and Andrews Resource Areas. The inventory included field location of selected wells and springs; measurement of ground-water levels, temperatures, specific conductance, and pH; and the collection of ground-water samples from selected sources to determine dissolved chemical constituents.

Included in this report are well data, drillers ' lithologic logs, hydrographs of observation wells, a summary of observation-well data, and chemical analyses of ground water.
