Hydrologic data for the alluvium and terrace aquifer of the Beaver-North Canadian River from the Panhandle to Canton Reservoir, northwestern Oklahoma

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).

The stratigraphic nomenclature is that of the Oklahoma Geological Survey and does.not necessarily agree with that of the U.S. Geological Survey.

Acknowledgement is extended to the residents of the study area for their cooperation in obtaining the data in this report.
