Scott C. Christenson Stephen P. Blumer Robert E. Davis 1981 <p>The U.S. Geological Survey has collected data on Oklahoma's groundwater resources since 1934. The data in this report were collected as part of a study in cooperation with the Oklahoma Water Resources Board to evaluate the geohydrology of the alluvium and terrace aquifer of the Beaver-North Canadian River 4] in northwestern Oklahoma. The data include records of approximately 900 wells, test-holes, and springs, results of chemical analyses of water from 30 wells tapping the aquifer, monthly water-level measurements for selected wells, and low-flow discharge measurements of the Beaver-North Canadian River and its tributaries (plate 1). All of the data were collected in the field during the period 1977-79. Information prior to this period is not included in this report but is contained in reports by Wood and Stacy (1965) and Morton (in press).</p><p>The stratigraphic nomenclature is that of the Oklahoma Geological Survey and does.not necessarily agree with that of the U.S. Geological Survey.</p><p>Acknowledgement is extended to the residents of the study area for their cooperation in obtaining the data in this report.</p> application/pdf 10.3133/ofr80159 en U.S. Geological Survey Hydrologic data for the alluvium and terrace aquifer of the Beaver-North Canadian River from the Panhandle to Canton Reservoir, northwestern Oklahoma reports
