    dct:description """This data set consists of digitized water-level elevation
contours for the Vamoosa-Ada aquifer in east-central Oklahoma.
The Vamoosa-Ada aquifer is an important source of water that
underlies about 2,320-square miles of parts of Osage, Pawnee,
Payne, Creek, Lincoln, Okfuskee, and Seminole Counties.
Approximately 75 percent of the water withdrawn from the
Vamoosa-Ada aquifer is for municipal use. Rural domestic use and
water for stock animals account for most of the remaining water
withdrawn. The Vamoosa-Ada aquifer is defined in a ground-water
report as consisting principally of the rocks of the Late
Pennsylvanian-age Vamoosa Formation and overlying Ada Group. The
Vamoosa-Ada aquifer consists of a complex sequence of fine- to
very fine-grained sandstone, siltstone, shale, and conglomerate
interbedded with very thin limestones. The water-yielding
capabilities of the aquifer are generally controlled by lateral
and vertical distribution of the sandstone beds and their
physical characteristics. The Vamoosa-Ada aquifer is unconfined
where it outcrops in about an 1,700-square-mile area.
		
The water-level elevation contours were digitized from a mylar
map, at a scale of 1:250,000, used to publish a plate in a
ground-water report about the Vamoosa-Ada aquifer. The
water-level elevation contours in this data set extend west of
the aquifer outcrop to areas where Vanoss Group rocks overlie
the Ada Group. The data set also includes a water-level
elevation contour for a terrace deposit east of the aquifer
outcrop near the North Canadian River. Water-level elevations
range from 800 to 1,000 feet above sea level for the Vamoosa-Ada
aquifer.""" ;
