Digital data sets that describe aquifer characteristics of the alluvial and terrace deposits along the Beaver-North Canadian River from the panhandle to Canton Lake in northwestern Oklahoma

This data set consists of digital water-level elevation contours
for the Quaternary alluvial and terrace deposits along the
Beaver-North Canadian River from the panhandle to Canton Lake in
northwestern Oklahoma in 1977 and 1978. Ground water in 830
square miles of the Quaternary-age alluvial and terrace aquifer
is an important source of water for irrigation, industrial,
municipal, stock, and domestic supplies. The aquifer consists of
poorly sorted, fine to coarse, unconsolidated quartz sand with
minor amounts of clay, silt, and basal gravel. The hydraulically
connected alluvial and terrace deposits unconformably overlie
the Tertiary-age Ogallala Formation and Permian-age formations.
The water-level elevations measured in 1977 and 1978 ranged from
2,260 feet above sea level in the northwest to 1,620 feet above
sea level in the southwest. The water-level elevation contours
were digitized from a folded paper map in a ground-water
modeling report about the aquifer. The source map was published
at a scale of 1:250,000.
