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.
This data set was created for a project to develop data sets to
support ground-water vulnerability analysis. The objective was
to create and document a digital geospatial data set from a
published report or map, or existing digital geospatial data
sets that could be used in ground-water vulnerability analysis.
Introduction --
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 (Christenson, 1983).
The aquifer boundaries established in a ground-water modeling
report (Christenson, 1983) 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 (Cederstrand, 1996a, 1996b, 1996c)
based on a scale of 1:250,000. The northwest and southeast
geographic limits of the aquifer and areas of little or no
saturated thickness were digitized from folded paper maps in the
ground-water modeling report, "Numerical simulation of the
alluvium and terrace aquifer along the North Canadian River from
Canton Lake to Lake Overholser, central Oklahoma," by
Christenson (1983, plates 1 and 6) at a scale of 1:250,000.
Reviews Applied to Data --
This electronic report was subjected to the same review standard
that applies to all U.S. Geological Survey reports. Reviewers
were asked to check the topological consistency, tolerances,
attribute frequencies and statistics, projection, and geographic
extent. Reviewers were given digital data sets and paper plots
for checking against the source maps to verify the linework and
attributes. The reviewers checked the metadata and a_readme.1st
files for completeness and accuracy.
Related Spatial and Tabular Data Sets --
This data set is one of four digital map data sets being published
together for this aquifer. The four data sets are:
> aqbound - aquifer boundaries
> cond - hydraulic conductivity
> recharg - aquifer recharge
> wlelev - water-level elevation contours
Digital map data sets of the Oklahoma surficial geology digitized from
1:250,000-scale maps (or 1:125,000-scale maps for the three Oklahoma
panhandle counties) are published separately.

Features representing aquifer boundaries as reported by
Christenson (1983) along geological contacts were extracted from
digital geology data sets by Cederstrand (1996a, 1996b, 1996c)
based on a scale of 1:250,000. Boundaries indicating the
geographic limits of the aquifer and areas of little or no
saturated thickness were digitized from a folded paper map at a
scale of 1:250,000 (Christenson, 1983). Aquifer boundaries
digitized from the (19 inches by 17 inches) base map had a maximum
registration root-mean-squared-error (RMSE) of 0.008 map inches
(0.020 map centimeters) or 169.03 feet (51.52 meters ground
distance. Boundaries represented at these scales are indicative of
broad, regional trends and should not be interpreted as site
specific.

This data set includes the aquifer boundaries published on plate 1
and includes the geographic limits of the aquifer and areas of
alluvial and terrace deposits having little or no saturated
thickness published on plate 6 of Christenson (1983). Some
Permian-age outcrops were included as part of the aquifer in the
finite-difference model grid, plate 5, by Christenson (1983).
These Permian-age outcrops were included as part of the aquifer
for modeling purpose only. These Permian-age outcrops are not
considered to be hydrologically connected with the aquifer by
Christenson (1983). These Permian-age outcrops, for this report,
are not considered part of the aquifer. The aquifer boundaries
with a value of 2 for the LSOURCE line attribute were taken from
Cederstrand (1996a, 1996b, 1996c).

Features representing aquifer boundaries along geological
contacts were extracted from digital geology data sets by
Cederstrand (1996a, 1996b, 1996c) using the ARC/INFO GET
command. The ARC/INFO CLEAN command (ESRI, 1995), was used
with a dangle length of 0.0 feet (0.0 meters) and fuzzy
tolerance of 32.8 feet (10.0 meters). ARC/INFO PROJECT command
(ESRI, 1995) was used to convert the report data set
projection from Albers Conical Equal Area to Universal
Transverse Mercator-Zone 14.
Geographic limits of the aquifer and areas of little or no
saturated thickness were digitized from a folded paper map
based on Transverse Mercator projection, with central
meridians of 99 and 97 degrees west longitude.
Nine registration tics, located at township and range corners
were projected into Universal Transverse Mercator-Zone 14. The
aquifer boundaries were digitized in one session with a
maximum registration root-mean-squared error (RMSE) of 0.008
inches (0.020 centimeters) map distance or 169.03 feet (51.52
meters) ground distance.
The data set was edited to delete extraneous pseudo and dangle
nodes. The ARC/INFO CLEAN command (ESRI, 1995) was used with
dangle length of 1000.0 meters and fuzzy tolerance of 328.1
feet (100.0 meters).
In the initial digitizing, the registration tics used were
township and range corners taken from 1:24,000-scale
topographic maps. A comparison of a paper plot of the report
data set with the source map showed that the corners used as
registration tics were not in the same locations on the
1:250,000-scale aquifer map. To correct the problem, three
1:250,000-scale U.S. Geological Survey quadrangle maps were
registered using latitudinal and longitudinal registration
tics, with a maximum registration root-mean-squared-error
(RMSE) of 0.008 inches (0.020 centimeters) map distance or
190.22 feet (57.98 meters) ground distance. Twenty-seven
registration tics were selected and digitized from the
quadrangle maps, and given the same tic identification numbers
as the tics that were used initially. These new tics were used
with the ARC/INFO TRANSFORM command (ESRI, 1995) to adjust the
digitized lines to more closely match the source map. The
root-mean-squared-error (RMSE) for TRANSFORM was 189.3 feet
(57.7 meters) ground distance. The ARC/INFO PROJECT command
(ESRI, 1995) was used to convert the data set projection from
Universal Transverse Mercator-Zone 14 to Transverse Mercator,
with central meridians of 99 and 97 degrees west longitude.
The ARC/INFO CLEAN command (ESRI, 1995), was used with a
dangle length of 328.1 feet (100.0 meters) and fuzzy tolerance
of 32.8 feet (10.0 meters). Polygons were attributed for
AQTYPE and lines were attributed for LSOURCE. Verification of
attribute codes was made by comparing a paper plot of the data
set with the source map. The ARC/INFO PROJECT command (ESRI,
1995) was used to convert the data set projection from
Universal Transverse Mercator-Zone 14 to Albers Conical Equal
Area.

Each polygon in this data set has an associated attribute,
AQTYPE, with values of 1 representing areas where the aquifer is
present, 2 representing areas where the aquifer is absent, and 3
representing areas where the aquifer was too thin (little or no
saturated thickness) to model ground-water flow (Christenson,
1983). AQTYPE is stored in the first major code (MAJOR1) for
polygons, and 0 is stored in the first minor code (MINOR1) in
the Digital Line Graph (DLG) version of this data set.
Each line in this digital data set has an associated attribute,
LSOURCE, that contains a code to indicate the line source. An
LSOURCE code of 1 indicates the line was digitized from
Christenson (1983), and an LSOURCE code of 2 indicates the line
was extracted from Cederstrand (1996a, 1996b, 1996c). LSOURCE is
stored in the first major code (MAJOR1) for lines, and 0 is
stored in the first minor code (MINOR1) in the Digital Line
Graph (DLG) version of this data set.
