Digital data sets that describe aquifer characteristics of the alluvial and terrace deposits along the North Canadian River from Canton Lake to Lake Overholser in central Oklahoma
Description
This data set consists of digital aquifer boundaries for the
alluvial and terrace deposits along the North Canadian River
from Canton Lake to Lake Overholser in central Oklahoma. Ground
water in approximately 400 square miles of Quaternary-age
alluvial and terrace aquifer is an important source of water for
irrigation, industrial, municipal, stock, and domestic supplies.
The aquifer consists of clay, silt, sand, and gravel. Sand-sized
sediments dominate the poorly sorted, fine to coarse,
unconsolidated quartz grains in the aquifer. The hydraulically
connected alluvial and terrace deposits unconformably overlie
Permian-age formations. The aquifer is overlain by a layer of
wind-blown sand in parts of the area.
The aquifer boundaries established in a ground-water modeling
report and are available in this data set include areas: 1)
where the alluvial and terrace deposits have been deposited
against relatively impermeable Permian-age formations; 2) where
the underlying Permian-age formations crop out within the
alluvial and the terrace deposits due to protruding high spots
on the Permian-age formations irregular surface; 3) where the
aquifer extends beyond the geographic limit of the study area
defined in the ground-water modeling report; and 4) where the
aquifer has little or no saturated thickness.
The lines in the data set representing aquifer boundaries along
geological contacts were extracted from published digital
surficial geology data sets based on a scale of 1:250,000.
Boundaries defining the northwest and southeast geographic
limits of the aquifer and areas of little or no saturated
thickness were digitized from folded paper maps, at a scale of
1:250,000, in the ground-water modeling report.
