This data set consists of digital polygons of constant hydraulic
conductivity values for the alluvial and terrace deposits along
the Cimarron River from Freedom to Guthrie in northwestern
Oklahoma. Ground water in 1,305 square miles of Quaternary-age
alluvial and terrace deposits along the the Cimarron River from
Freedom to Guthrie is an important source of water for
irrigation, industrial, municipal, stock, and domestic
supplies. Alluvial and terrace deposits are composed of
interfingering lenses of clay, sandy clay, and cross-bedded
poorly sorted sand and gravel. The aquifer is composed of
hydraulically connected alluvial and terrace deposits that
unconformably overlie the Permian-age Formations.
The hydraulic-conductivity values for alluvial and terrace
deposits used in this data set were published in a steady-state
ground-water flow modeling report. The aquifer boundaries along
geological contacts were extracted from published digital
geology data sets. Boundaries defining the geographic limits of
the aquifer were digitized from a mylar map, at a scale of
1:250,000. The maps were published at a scale of 1:900,000. The
hydraulic conductivity values are 104.5 feet per day for the
alluvial deposits and 47.5 feet per day for the terrace
deposits.
Ground-water flow models are numerical representations that
simplify and aggregate natural systems. Models are not unique;
different combinations of aquifer characteristics may produce
similar results. Therefore, values of hydraulic conductivity
used in the model and presented in this data set are not
precise, but are within a reasonable range when compared to
independently collected data.
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
set that could be used in ground-water vulnerability analysis.
Introduction --
This data set consists of digital polygons of constant hydraulic
conductivity values for the alluvial and terrace deposits along
the Cimarron River from Freedom to Guthrie in northwestern
Oklahoma. Ground water in 1,305 square miles of Quaternary-age
alluvial and terrace deposits along the Cimarron River from
Freedom to Guthrie is an important source of water for
irrigation, industrial, municipal, stock, and domestic
supplies. Alluvial and terrace deposits are composed of
interfingering lenses of clay, sandy clay, and cross-bedded
poorly sorted sand and gravel. The alluvial and terrace deposits
along the Cimarron River are hydraulically connected and
unconformably overlie Permian-age Formations (Adams and Bergman,
1996).
The hydraulic-conductivity values reported in Adams and Bergman
(1996) and used in this report for alluvial and terrace deposits
were determined during the calibration of a steady-state
ground-water flow model of the alluvial and terrace deposits.
The hydraulic conductivity values are 104.5 feet per day for the
alluvial deposits and 47.5 feet per day for the terrace deposits
(Adams and Bergman (1996). The Digital Line Graph (DLG) format
requires numbers to be stored as integers. Therefore, the
hydraulic conductivity in feet per day was multiplied by 10 and
stored in the digital data sets as tenths of a foot per day. For
example 47.5 feet per day was multiplied by 10 and stored in the
digital data sets as 475 tenths of a foot per day.
The polygon boundaries and constant hydraulic conductivity
values were determined from the U.S. Geological Survey
publication, "Geohydrology of alluvium and terrace deposits of
the Cimarron River from Freedom to Guthrie, Oklahoma," by Adams
and Bergman (1996, fig. 5 and p. 44). The aquifer boundaries
along geological contacts were extracted from digital geology
data sets by Cederstrand (1996a, 1996b, 1996c, 1996d).
Boundaries defining the geographic limits of the aquifer were
digitized from a mylar map, at a scale of 1:250,000. The maps
were published at a scale of 1:900,000 (Adams and Bergman,
1996).
Ground-water flow models are numerical representations that
simplify and aggregate natural systems. Models are not unique;
different combinations of aquifer characteristics may produce
similar results. The hydraulic conductivity and recharge are
closely interrelated. As long as these two model inputs are in
balance the model has a small mean residual; it represents the
natural system numerically. If the hydraulic conductivity is
accurately known, the model can be used to accurately determine
recharge. Likewise, if the hydraulic conductivity is poorly
known, then the recharge will be poorly determined.
Therefore, values of hydraulic conductivity used in the model
and presented in this data set are not precise, but are within a
reasonable range when compared to independently collected data.
In most aquifers, hydraulic conductivity measurements made in
wells or in cores will range over several orders of magnitude,
even over short horizontal and vertical distances. Hydraulic
conductivity values derived from ground-water flow models
represent areal generalizations and do not reflect the large
local variance in well or core measurements.
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.

Lines representing geological contacts were extracted from
digital geology data sets (Cederstrand, 1996a, 1996b, 1996c,
1996d) based on a scale of 1:250,000. Lines representing the
geographic limits of the aquifer were digitized from a mylar
map (33 inches by 31 inches), at a scale of 1:250,000.
Hydraulic conductivity polygons represented at these scales
are indicative of broad, regional trends and should not be
interpreted as site specific. The hydraulic conductivity
polygons that were digitized from a mylar map had a maximum
root-mean-squared-error (RMSE) of 0.008 map inches (0.020 map
centimeters) or 167.49 feet (51.05 meters) ground distance.

(1996). Lines with a value of 2 for the LSOURCE line attribute were

The features for aquifer boundaries along geological contacts
were extracted from Cederstrand (1996a, 1996b, 1996c, 1996d)
digital geology data sets using the ARC/INFO GET command
(ESRI, 1995). The ARC/INFO CLEAN command (ESRI, 1995) was used
to process the polygon data set with a dangle length of 0.0
feet or meters and fuzzy tolerance of 3.3 feet (1.0 meters).
The ARC/INFO PROJECT command (ESRI, 1995) was used to convert
the extracted features data set projection from Albers Conical
Equal Area to Universal Transverse Mercator-Zone 14.
1996
Boundaries defining the geographic limits of the aquifer and
areas of less than 5 feet saturated thickness were digitized
from a mylar map, at a scale of 1:250,000. The mylar map was
based on Transverse Mercator projection, with central
meridians of 99 and 97 degrees west longitude. Registration
tics were located on the report data set and the mylar map at
locations of township and range corners, to allow registration
of the digitized data set and mylar map. The 4 registration
tics were projected into Universal Transverse Mercator-Zone
14, which was the projection used for manual digitizing. The
aquifer boundaries were digitized in three sessions with a
maximum root-mean-squared-error (RMSE) of 0.008 inches (0.020
centimeters) map distance or 167.49 feet (51.05 meters) ground
distance. The data set was edited to delete extraneous pseudo
and dangle nodes.
1996
The registration tics used in the initial digitizing were
township and range corners taken from 1:24,000-scale topographic
maps. A comparison of a paper copy of the digital data set with
the source map showed that the 1:24,000-scale township and range
corners used as registration tics were not in the same locations
on the 1:250,000-scale source map. To correct the problem, four
1:250,000-scale U.S. Geological Survey quadrangle maps were
registered using latitudinal and longitudinal tics, with a
maximum root-mean-squared-error (RMSE) of 0.003 inches (0.008
centimeters) map distance or 69.09 feet (21.06 meters) ground
distance. Forty-four 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 tics 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. A comparison of this transformed data
set to the pretransformed data set showed no difference in the
digitized aquifer boundaries.
1996
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. The data set was changed from
double to single precision with the ARC/INFO COPY (single)
command (ESRI, 1995). The ARC/INFO CLEAN command (ESRI, 1995)
was used to process the new polygon data set with a dangle
length of 0.0 feet (0.0 meters) and fuzzy tolerance of 53.8 feet
(16.4 meters). Polygons were attributed for AQTYPE and lines
were attributed for LSOURCE. Verification of attribute codes
were made by comparing a paper plot of the data set with the
source map. The lines were attributed for LSOURCE and polygons
were attributed for K. Verification of attribute codes were
made by comparing a paper plot of the digital data set with
the source map.

Each polygon in this data set has an associated attribute, K,
containing hydraulic conductivity values expressed in tenth of a foot
per day. For example, the hydraulic conductivity of 47.5 feet per day
is stored as a K value of 475. A K value of -99999 indicates the
hydraulic conductivity is unknown. K 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. A LSOURCE
code of 1 indicates the line was digitized from Adams and Bergman
(1996), and a LSOURCE code of 2 indicates the line was extracted from
Cederstrand (1996a, 1996b, 1996c, 1996d). 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.
