Environmental Characteristics and Geographic
Information System Applications for the Development of
Nutrient Thresholds in Oklahoma Streams
By Jason R. Masoner, Brian E. Haggard, and Alan Rea
Abstract
The U.S. Environmental Protection Agency has developed
nutrient criteria using ecoregions to manage and protect rivers
and streams in the United States. Individual states and tribes are
encouraged by the U.S. Environmental Protection Agency to
modify or improve upon the ecoregion approach. The Okla-homa
Water Resources Board uses a dichotomous process that
stratifies streams using environmental characteristics such as
stream order and stream slope. This process is called the Use
Support Assessment Protocols, subchapter 15. The Use Support
Assessment Protocols can be used to identify streams threat-ened
by excessive amounts of nutrients, dependant upon a ben-eficial
use designation for each stream. The Use Support
Assessment Protocols, subchapter 15 uses nutrient and environ-mental
characteristic thresholds developed from a study con-ducted
in the Netherlands, but the Oklahoma Water Resources
Board wants to modify the thresholds to reflect hydrologic and
ecological conditions relevant to Oklahoma streams and rivers.
Environmental characteristics thought to affect impair-ment
from nutrient concentrations in Oklahoma streams and
rivers were determined for 798 water-quality sites in Oklahoma.
Nutrient, chlorophyll, water-properties, and location data were
retrieved from the U.S. Environmental Protection Agency
STORET database including data from the U.S. Geological
Survey, Oklahoma Conservation Commission, and Oklahoma
Water Resources Board. Drainage-basin area, stream order,
stream slope, and land-use proportions were determined for
each site using a Geographic Information System. The methods,
procedures, and data sets used to determine the environmental
characteristics are described.
Introduction
The U.S. Environmental Protection Agency has developed
nutrient criteria using ecoregions to manage and protect rivers
and streams in the United States from impairment (Robertson,
Saad, and Wieben, 2001). Individual states and tribes are
encouraged by the U.S. Environmental Protection Agency to
modify or improve upon the ecoregion approach. (Robertson,
Saad, and Wieben, 2001). The Oklahoma Water Resources
Board (OWRB) developed a dichotomous process that stratifies
or groups streams using environmental characteristics such as
stream order and stream slope to identify streams that need fur-ther
study to determine if they are impaired (OWRB, 2001).
This process is called the Use Support Assessment Protocols,
subchapter 15 (USAP). The OWRB is using nutrient and envi-ronmental
characteristic thresholds developed in the Nether-lands
(Peters and Gardeniers, 1998; OWRB, 2001). The USAP
can be used to identify streams threatened by excessive amounts
of nutrients, dependant upon a beneficial use designation for
each stream. Nutrient criteria are not synonymous with water-quality
standards. The purpose of the USAP is to identify
streams, based on nutrient and environmental characteristic
thresholds for each stream, that may be threatened by excessive
amounts of nutrients and impairment of their beneficial use.
Further studies would be required to determine if water-quality
standards are exceeded.
The U.S. Geological Survey, in cooperation with the Okla-homa
Water Resources Board, is providing descriptive statistics
of water-quality sampling sites that can be used to modify the
USAP to reflect hydrological and ecological conditions relevant
to Oklahoma streams and rivers. Four environmental character-istics
-- drainage-basin area, stream order, stream slope, and
land-use proportions -- that affect nutrient concentrations in
Oklahoma streams were compiled using a Geographic Informa-tion
System (GIS) and are provided in appendix 1 (back of
report). These characteristics, when used in conjunction with
water-quality data collected from Federal, State, tribal, and
local programs, will help evaluate streams in Oklahoma and
through statistical models, help determine which streams are
nutrient threatened.
Purpose and Scope
This report describes the methods, procedures, and data
sets used to determine environmental characteristics and pro-vides
a list of the environmental characteristics (appendix 1,
back of report) that can be used to help modify the USAP
thresholds to represent hydrological and ecological conditions
relevant to streams in Oklahoma. Nutrient, chlorophyll, water-properties,
and location data were retrieved for 798 water-qual-ity
sites from the U. S. Environmental Protection Agency
STORET database (U.S. Environmental Protection Agency,
2001), the Oklahoma Conservation Commission, and the Okla-homa
Water Resources Board. STORET included data col-lected
by the U.S. Geological Survey.
2 Environmental Characteristics and Geographic Information System Applications for the Development of Nutrient Thresholds
in Oklahoma Streams
The 798 water-quality sites are located in Oklahoma, but
the geographic scope of the data sets used to derive environ-mental
characteristics included the Arkansas-Red River drain-age
basins, an area of about 202,000 square miles (fig. 1). There
are many sampling sites listed in appendix 1 that are reported as
having different site identification numbers but have identical
latitude and longitude coordinates. This is because there are
multiple federal and state agencies collecting and maintaining
independent water-quality databases that use different proce-dures
for designating site identification numbers. This report
provides environmental characteristics for each water-quality
site so that the agencies responsible for maintaining a particular
site would have access to environmental characteristics through
the site identification number. The water-quality sites are not
labeled on figure 1, as many of the sites are extremely close
together and the purpose of this report is to provide the environ-mental
characteristics and to describe the methods, procedures,
and data sets used to determine the environmental characteris-tics.

Environmental Characteristics and GIS
Applications
Drainage-basin areas
Drainage-basin areas for 798 water-quality sites in Okla-homa
were determined from several data sources using ARC/
INFO (ESRI, 2001a) and ARC/VIEW (ESRI, 2001b) GIS
applications. Topographic data sets of flow direction and flow
accumulation were used to delineate drainage basins. Flow-direction
and flow-accumulation data sets were created from a
hydrologically conditioned Digital Elevation Model (DEM)
with a 60-meter cell size. The DEM was created from elevation
data (hypsography) and stream data (hydrography) from digital
versions of the U.S. Geological Survey 1:100,000-scale topo-graphic
maps (Cederstrand and Rea, 1995).
Development of flow-direction and flow-accumulation
data sets is an important step in delineating drainage basins
using DEMs. A flow-direction data set (fig. 2) contains cell val-ues
that indicate the direction water will flow out of each cell
based on elevation (Jenson and Domingue, 1988). A coding
structure developed by Jenson and Domingue, (1988) codes
cells based on the orientation with respect to one of the eight
neighboring cells. The coding structure uses slope calculations
between neighboring cells to code individual cells. Slope is cal-culated
from the change in elevation between cells divided by
the distance between cell centers. The distance between cell
centers for diagonal cells is measured by multiplying the cell
size by the square root of two.
The flow accumulation grid (fig. 3) contains cell
values computed from the flow direction grid that equal
the number of cells that flow into it. Cells having a flow
accumulation value of zero (to which no other cells flow)
generally correspond to the pattern of ridges (Jenson and
Domingue, 1988). Cells that have many other cells
flowing into it usually are representative of streams or
rivers.
The ARC/INFO GRID module was used to delin-eate
drainage basins and compute corresponding basin
areas (ESRI, 2001a). Individual water-quality sites were
used to define a pour point (an outlet for a drainage area)
from which a complete or partial drainage basin was
created. An automated process was developed that itera-tively
selected a water-quality site, converted it into a
pour point, snapped the pour point to cells of high flow-accumulation,
and delineated a drainage basin for that
site. The RESELECT command selected a single water-quality
site and the POINTGRID command converted the
point into a grid point. The SNAPPOUR command
adjusted the points to cells of high flow accumulation and
the WATERSHED function delineated the drainage area
using the flow-accumulation and flow-direction data sets.
A partial drainage basin was created when the
drainage basin for a water-quality site extended beyond
the coverage of the flow-direction and flow-accumulation
data sets of Cederstrand and Rea (1995), which were
limited to a small margin around Oklahoma. Additional
techniques using the ARC/VIEW GEOPROCESSING
(ESRI, 2001b) extension were used to complete drainage
basins. Partial drainage basins were completed by
appending the most detailed digital hydrologic unit maps
available for that area. Two hydrologic unit data sets,
Seaber and others (1984) and Kansas Data Access and
Support Center (2000), were used to complete partially
defined drainage basins. The UNION operation appended
the partially defined drainage basin and the hydrologic
unit maps. The DISSOLVE operation eliminated small
sliver polygons created from the UNION operation. This
method resulted in one polygon unit that represented the
drainage-basin area. Drainage-basin areas for each water-quality
site are listed in appendix 1 (back of report).
Stream Order
Stream order was calculated using methods developed by
Strahler (1952) and a stream data set created from a hydrologic
derivative (flow accumulation) of the U.S. Geological Survey
National Elevation Dataset (NED). NED is spatially referenced
in a geographic coordinate system using degrees, minutes, and

seconds as units of measurement. NED is based on 1:24,000-
scale topographic maps and has a resolution of one arc-second
(equivalent to 30 meters). The NED data were projected to an
Albers Equal Area projection and resampled to a 30-meter pixel
resolution. Flow-direction and flow-accumulation data sets
were created for the Arkansas-White-Red River basin (fig. 1)
using the FILL, FLOWDIRECTION, and FLOWACCUMU-LATION
functions (Elevation Derivatives for National Appli-cations,
2001). These data sets (hydrologic derivatives of the
NED) are similar to derivatives of the 60-meterDEMdeveloped
by Cederstrand and Rea (1995) used to delineate drainage
basins.
The stream network needs to have a constant stream den-sity
and include all upstream headwaters to calculate stream
order. Stream density can be expressed as a measure of close-ness
between stream channels. A stream network that varies in
stream density will produce higher stream order values in more
dense areas and lower stream order values in less dense areas.
Figure 4 shows U.S. Geological Survey 1:100,000-scale topo-graphic
quadrangle boundaries and the National Hydrography
Dataset (NHD) (2001). The varying stream density is shown
in the upper Bristow quadrangle in relation to stream density in
the lower Shawnee quadrangle. This variation in stream density
is due to varying detail during the digitizing process.
A detailed and consistent stream network was created
using the ARC/INFO GRID function STREAMLINE to con-vert
the raster linear network (flow accumulation) to a vector
linear network (synthetic hydrography) that represented
streams at a consistent density (fig. 5). The synthetic hydrogra-phy
data set was created using a threshold of 5,000 30-meter
cells from the flow accumulation grid. Cell threshold has a
direct affect on the length of headwater streams and minimum
size of drainage-basin areas that can be delineated. The mini-mum
size drainage basin that could be delineated based on a
threshold of 5,000 30-meter cells is 1.7 square miles. Increasing
or decreasing the cell threshold directly affects the length of the
synthetic hydrography. Although the derived synthetic hydrog-raphy
is based on 1:24,000-scale topographic maps, derived 1st
order streams, in areas of low topographic relief, may actually
be a 2nd order stream when manually determined using
1:24,000-scale topographic map. In areas of high topographic
relief, stream order values derived using the synthetic hydrog-raphy
were consistent with stream order values determined
manually using 1:24,000-scale topographic maps.
A program was used to assign stream order values for
streams in the synthetic hydrography data set using methods
developed by Strahler (1957; fig. 6).
The beginning or headwater streams are designated as
first-order streams. A second-order stream is formed when two
first-order streams intersect; when two second-order streams
intersect, a third-order stream is formed; and so forth. The
ARC/INFO NEAR command was used to locate the stream
nearest to a water-quality site and transfer the stream order
value to the water-quality site. The derived stream order values
were transferred to the environmental characteristic data set
(appendix 1, back of report).

Immediate Stream-Channel Slope
The immediate stream-channel slope is defined in this
report as the change in elevation between beginning and ending
points of a stream segment divided by the length of the stream
segment. The average length of a stream segment used to com-pute
the immediate stream-channel slope was 1.75 miles. The
minimum and maximum lengths used were .31 mile and 3.1
miles, respectively. Stream slope varied slightly when checked
against slope values determined manually from 1:24,000-scale
topographic maps.
Basin characteristics such as stream slope can be problem-atic
because the length measured is highly dependent on scale
or in this case, dependent on the cell threshold used to create
synthetic hydrography. Flow-accumulation data sets, and the
DEM created by Cederstrand and Rea (1995) were used to cal-culate
the immediate stream-channel slope for each of the 798
water-quality sites. The “Drainage-basin areas” section of this
report provides specific information about topographic data sets
created by Cederstrand and Rea.
A vector linear network that represented Oklahoma
streams was created from the flow-accumulation data set using
the ARC/INFO GRID function STREAMLINE. The flow-accumulation
and flow-direction data sets created by Ceder-strand
and Rea (1995) were designed specifically for defining
watersheds; therefore, the corresponding stream network is
very dense and file size is very large. To decrease file size and
reduce processing times, the ARC/INFO BUFFER command
was used to select only the streams within a 5,000-meter dis-tance
from the water-quality sites (fig. 7). This method
decreased the number of arcs from 567,727 to 58,794 arcs.
The NODEPOINT command was used to create points for
each node in the stream data set. A node is defined as the begin-ning
or ending point of a line; therefore, any confluence of
streams would be represented as a node. A unique identification
code for each point was used that linked the points back to

the nodes in the stream data set. The LATTICESPOT com-mand
was used to overlay the point data onto the DEM and
interpolate an elevation value from the underlying neighboring
cells. The elevation values were transferred from the point data
set to nodes in the stream data set using the RELATE and
MOVE commands.
The CALCULATE command was used to compute the
change in elevation between nodes, divided by the distance
between nodes. This calculation resulted in the immediate
stream-channel slope for stream segments near water-quality
sites (fig. 7). The NEAR command was used to locate the near-est
stream segment for each water-quality site and transfer the
slope value to the water-quality data set. The stream slope val-ues
were transferred to the environmental characteristic data set
(appendix 1, back of report).
Land Use
Land-use proportions were computed for each of the 798
drainage-basin areas using the ARC/INFO GRID module and
land-use information from the National Land Cover Dataset
(NLCD) (2000). The NLCD is based on 30-meter Landsat The-matic
Mapper (TM) data acquired by the Multi-Resolution
Land Characterization (MRLC) Consortium. The base data set
for the NLCD project was compiled using leaves-off Landsat
TM data, nominal-1992 acquisitions and other ancillary leaves-on
LandsatTMdata. The NLCD data set consists of 21 land-use
categories (table 1). These land-use categories were aggre-gated
to produce a land-use data set that consisted of 11 land-use
categories (table 2).

A land-use data set was compiled for the Arkansas-White-
Red River basin (fig.1). The ARC/INFO MASK command was
used to clip out land-use information for each drainage basin.
This method produced a land-use data set for each drainage
area. Land-use proportions within each drainage basin were cal-culated
by dividing the number of cells of a given category by
the total number of cells in a drainage basin multiplied by 100
to yield the percent land-use. The land-use proportions were
appended to the environmental characteristic data set (appendix
1, back of report).
Summary
The U.S. Environmental Protection Agency (USEPA) has
developed nutrient criteria using ecoregions to manage and pro-tect
rivers and streams in the United States. Individual states
and tribes are encouraged by the U.S. Environmental Protection
Agency to modify or improve upon the ecoregion approach.
The Oklahoma Water Resources Board (OWRB) has developed
a dichotomous process that stratifies or groups streams based on
environmental characteristics such as stream order and stream
slope; this process is commonly known as the Use Support
Assessment Protocols, subchapter 15 (USAP). The OWRB is
using nutrient and environmental characteristic thresholds
developed from a study conducted in the Netherlands. The U.S.
Geological Survey, in cooperation with the OWRB, is provid-ing
descriptive statistics of water-quality sampling sites that can
be used to modify the USAP to reflect hydrological and ecolog-ical
conditions relevant to Oklahoma streams and rivers. Four
environmental characteristics -- drainage-basin area, stream
slope, stream order, and land-use proportions -- that affect nutri-ent
concentrations in Oklahoma streams were compiled using a
Geographic Information System and are provided in appendix 1
(back of report).
Data sets of flow-direction and flow-accumulation (also
referred to as hydrologic derivatives) were used to define drain-age
basins for 798 water-quality sites in Oklahoma. The ARC/
INFO GRID module was used to create drainage basins and
compute corresponding areas. Individual water-quality sites
were used to define a pour point (an outlet for a drainage area)
from which a complete or partial drainage basin was created.
An automated process was developed that iteratively selected a
water-quality site, converted it into a pour point, snapped the
pour point to cells of high flow-accumulation, and delineated a
drainage basin for that site. Over 400 drainage basins extended
beyond the coverage of the flow-accumulation and flow-direc-tion
data sets developed by Cederstrand and Rea (1995). The
ARC/VIEW GEOPROCESSING extension was used to append
drainage partially defined drainage areas to the most detailed
digital hydrologic unit maps available for those areas.
Stream order was calculated using methods developed by
Strahler (1952) and a stream data set created from a hydrologic
derivative (flow accumulation) of the U.S. Geological Survey
National Elevation Dataset (NED). The stream data set derived
from the flow accumulation dataset modeled streams in Okla-homa
at a consistent stream density. A program was used to
assign stream order values for streams in the synthetic hydrog-raphy
data. The beginning or headwater streams are designated
as a first-order stream. A second-order stream is formed when
two first-order streams intersect; when two second-order
streams intersect, a third-order stream is formed; and so forth.

The immediate stream-channel slope for each of the 798
water-quality sites was calculated using flow-accumulation and
Digital Elevation Model data sets. A vector linear network that
represented streams in Oklahoma at a consistent density was
created from the flow-accumulation data set. A point data set
was made from each beginning and ending node in the stream
data set. A unique identification code was used that linked the
point data set to the stream data set. The point data set was used
to overlay the DEM and extract elevation information for each
point. Elevations for each point were transferred to the nodes in
the stream data set using unique identification codes. A simple
calculation using the change in elevation between nodes,
divided by the distance between nodes, was performed to calcu-late
the immediate stream-channel slope for stream segments
near water-quality sites.
Land-use proportions were computed for each of the 798
drainage-basin areas using the ARC/INFO GRID module and
land-use information from the National Land Cover Dataset
(NLCD). The NLCD is based on 30-meter Landsat Thematic
Mapper (TM) data acquired by the Multi-Resolution Land
Characterization (MRLC) Consortium. The base data set for the
NLCD project was compiled using leaves-off LandsatTMdata,
nominal-1992 acquisitions and other ancillary leaves-on Land-sat
TM data. The NLCD data set consists of twenty-one land-use
categories. These land-use categories were aggregated to
produce a land-use data set that consisted of 11 land-use cate-gories.
A land-use data set was compiled for the Arkansas-
White-Red River basin. Drainage-basin boundaries were used
to select only the land-use information inside the drainage
basins. Land-use proportions within each drainage basin were
calculated by dividing the number of cells of given category by
the total number of cells in a drainage basin multiplied by 100.

Masoner, Brian E. Haggard, and Alan Rea Abstract The U.S. Environmental Protection Agency has developed nutrient criteria using ecoregions to manage and protect rivers and streams in the United States. Individual states and tribes are encouraged by the U.S. Environmental Protection Agency to modify or improve upon the ecoregion approach. The Okla-homa Water Resources Board uses a dichotomous process that stratifies streams using environmental characteristics such as stream order and stream slope. This process is called the Use Support Assessment Protocols, subchapter 15. The Use Support Assessment Protocols can be used to identify streams threat-ened by excessive amounts of nutrients, dependant upon a ben-eficial use designation for each stream. The Use Support Assessment Protocols, subchapter 15 uses nutrient and environ-mental characteristic thresholds developed from a study con-ducted in the Netherlands, but the Oklahoma Water Resources Board wants to modify the thresholds to reflect hydrologic and ecological conditions relevant to Oklahoma streams and rivers. Environmental characteristics thought to affect impair-ment from nutrient concentrations in Oklahoma streams and rivers were determined for 798 water-quality sites in Oklahoma. Nutrient, chlorophyll, water-properties, and location data were retrieved from the U.S. Environmental Protection Agency STORET database including data from the U.S. Geological Survey, Oklahoma Conservation Commission, and Oklahoma Water Resources Board. Drainage-basin area, stream order, stream slope, and land-use proportions were determined for each site using a Geographic Information System. The methods, procedures, and data sets used to determine the environmental characteristics are described. Introduction The U.S. Environmental Protection Agency has developed nutrient criteria using ecoregions to manage and protect rivers and streams in the United States from impairment (Robertson, Saad, and Wieben, 2001). Individual states and tribes are encouraged by the U.S. Environmental Protection Agency to modify or improve upon the ecoregion approach. (Robertson, Saad, and Wieben, 2001). The Oklahoma Water Resources Board (OWRB) developed a dichotomous process that stratifies or groups streams using environmental characteristics such as stream order and stream slope to identify streams that need fur-ther study to determine if they are impaired (OWRB, 2001). This process is called the Use Support Assessment Protocols, subchapter 15 (USAP). The OWRB is using nutrient and envi-ronmental characteristic thresholds developed in the Nether-lands (Peters and Gardeniers, 1998; OWRB, 2001). The USAP can be used to identify streams threatened by excessive amounts of nutrients, dependant upon a beneficial use designation for each stream. Nutrient criteria are not synonymous with water-quality standards. The purpose of the USAP is to identify streams, based on nutrient and environmental characteristic thresholds for each stream, that may be threatened by excessive amounts of nutrients and impairment of their beneficial use. Further studies would be required to determine if water-quality standards are exceeded. The U.S. Geological Survey, in cooperation with the Okla-homa Water Resources Board, is providing descriptive statistics of water-quality sampling sites that can be used to modify the USAP to reflect hydrological and ecological conditions relevant to Oklahoma streams and rivers. Four environmental character-istics -- drainage-basin area, stream order, stream slope, and land-use proportions -- that affect nutrient concentrations in Oklahoma streams were compiled using a Geographic Informa-tion System (GIS) and are provided in appendix 1 (back of report). These characteristics, when used in conjunction with water-quality data collected from Federal, State, tribal, and local programs, will help evaluate streams in Oklahoma and through statistical models, help determine which streams are nutrient threatened. Purpose and Scope This report describes the methods, procedures, and data sets used to determine environmental characteristics and pro-vides a list of the environmental characteristics (appendix 1, back of report) that can be used to help modify the USAP thresholds to represent hydrological and ecological conditions relevant to streams in Oklahoma. Nutrient, chlorophyll, water-properties, and location data were retrieved for 798 water-qual-ity sites from the U. S. Environmental Protection Agency STORET database (U.S. Environmental Protection Agency, 2001), the Oklahoma Conservation Commission, and the Okla-homa Water Resources Board. STORET included data col-lected by the U.S. Geological Survey. 2 Environmental Characteristics and Geographic Information System Applications for the Development of Nutrient Thresholds in Oklahoma Streams The 798 water-quality sites are located in Oklahoma, but the geographic scope of the data sets used to derive environ-mental characteristics included the Arkansas-Red River drain-age basins, an area of about 202,000 square miles (fig. 1). There are many sampling sites listed in appendix 1 that are reported as having different site identification numbers but have identical latitude and longitude coordinates. This is because there are multiple federal and state agencies collecting and maintaining independent water-quality databases that use different proce-dures for designating site identification numbers. This report provides environmental characteristics for each water-quality site so that the agencies responsible for maintaining a particular site would have access to environmental characteristics through the site identification number. The water-quality sites are not labeled on figure 1, as many of the sites are extremely close together and the purpose of this report is to provide the environ-mental characteristics and to describe the methods, procedures, and data sets used to determine the environmental characteris-tics. Acknowledgments The authors thank Robert Tortorelli, Evan Hornig, and Lyn Osburn of the U.S. Geological Survey for their contribu-tions to this report. Environmental Characteristics and GIS Applications Drainage-basin areas Drainage-basin areas for 798 water-quality sites in Okla-homa were determined from several data sources using ARC/ INFO (ESRI, 2001a) and ARC/VIEW (ESRI, 2001b) GIS applications. Topographic data sets of flow direction and flow accumulation were used to delineate drainage basins. Flow-direction and flow-accumulation data sets were created from a hydrologically conditioned Digital Elevation Model (DEM) with a 60-meter cell size. The DEM was created from elevation data (hypsography) and stream data (hydrography) from digital versions of the U.S. Geological Survey 1:100,000-scale topo-graphic maps (Cederstrand and Rea, 1995). Development of flow-direction and flow-accumulation data sets is an important step in delineating drainage basins using DEMs. A flow-direction data set (fig. 2) contains cell val-ues that indicate the direction water will flow out of each cell based on elevation (Jenson and Domingue, 1988). A coding structure developed by Jenson and Domingue, (1988) codes cells based on the orientation with respect to one of the eight neighboring cells. The coding structure uses slope calculations between neighboring cells to code individual cells. Slope is cal-culated from the change in elevation between cells divided by the distance between cell centers. The distance between cell centers for diagonal cells is measured by multiplying the cell size by the square root of two. The flow accumulation grid (fig. 3) contains cell values computed from the flow direction grid that equal the number of cells that flow into it. Cells having a flow accumulation value of zero (to which no other cells flow) generally correspond to the pattern of ridges (Jenson and Domingue, 1988). Cells that have many other cells flowing into it usually are representative of streams or rivers. The ARC/INFO GRID module was used to delin-eate drainage basins and compute corresponding basin areas (ESRI, 2001a). Individual water-quality sites were used to define a pour point (an outlet for a drainage area) from which a complete or partial drainage basin was created. An automated process was developed that itera-tively selected a water-quality site, converted it into a pour point, snapped the pour point to cells of high flow-accumulation, and delineated a drainage basin for that site. The RESELECT command selected a single water-quality site and the POINTGRID command converted the point into a grid point. The SNAPPOUR command adjusted the points to cells of high flow accumulation and the WATERSHED function delineated the drainage area using the flow-accumulation and flow-direction data sets. A partial drainage basin was created when the drainage basin for a water-quality site extended beyond the coverage of the flow-direction and flow-accumulation data sets of Cederstrand and Rea (1995), which were limited to a small margin around Oklahoma. Additional techniques using the ARC/VIEW GEOPROCESSING (ESRI, 2001b) extension were used to complete drainage basins. Partial drainage basins were completed by appending the most detailed digital hydrologic unit maps available for that area. Two hydrologic unit data sets, Seaber and others (1984) and Kansas Data Access and Support Center (2000), were used to complete partially defined drainage basins. The UNION operation appended the partially defined drainage basin and the hydrologic unit maps. The DISSOLVE operation eliminated small sliver polygons created from the UNION operation. This method resulted in one polygon unit that represented the drainage-basin area. Drainage-basin areas for each water-quality site are listed in appendix 1 (back of report). Stream Order Stream order was calculated using methods developed by Strahler (1952) and a stream data set created from a hydrologic derivative (flow accumulation) of the U.S. Geological Survey National Elevation Dataset (NED). NED is spatially referenced in a geographic coordinate system using degrees, minutes, and Figure 1. Locations of water-quality sites, study area, and geographic scope of data sets used to determine environmental characteristics. Environmental Characteristics and GIS Applications 5 Figure 2.

NED is based on 1:24,000- scale topographic maps and has a resolution of one arc-second (equivalent to 30 meters). The NED data were projected to an Albers Equal Area projection and resampled to a 30-meter pixel resolution. Flow-direction and flow-accumulation data sets were created for the Arkansas-White-Red River basin (fig. 1) using the FILL, FLOWDIRECTION, and FLOWACCUMU-LATION functions (Elevation Derivatives for National Appli-cations, 2001). These data sets (hydrologic derivatives of the NED) are similar to derivatives of the 60-meterDEMdeveloped by Cederstrand and Rea (1995) used to delineate drainage basins. The stream network needs to have a constant stream den-sity and include all upstream headwaters to calculate stream order. Stream density can be expressed as a measure of close-ness between stream channels. A stream network that varies in stream density will produce higher stream order values in more dense areas and lower stream order values in less dense areas. Figure 4 shows U.S. Geological Survey 1:100,000-scale topo-graphic quadrangle boundaries and the National Hydrography Dataset (NHD) (2001). The varying stream density is shown in the upper Bristow quadrangle in relation to stream density in the lower Shawnee quadrangle. This variation in stream density is due to varying detail during the digitizing process. A detailed and consistent stream network was created using the ARC/INFO GRID function STREAMLINE to con-vert the raster linear network (flow accumulation) to a vector linear network (synthetic hydrography) that represented streams at a consistent density (fig. 5). The synthetic hydrogra-phy data set was created using a threshold of 5,000 30-meter cells from the flow accumulation grid. Cell threshold has a direct affect on the length of headwater streams and minimum size of drainage-basin areas that can be delineated. The mini-mum size drainage basin that could be delineated based on a threshold of 5,000 30-meter cells is 1.7 square miles. Increasing or decreasing the cell threshold directly affects the length of the synthetic hydrography. Although the derived synthetic hydrog-raphy is based on 1:24,000-scale topographic maps, derived 1st order streams, in areas of low topographic relief, may actually be a 2nd order stream when manually determined using 1:24,000-scale topographic map. In areas of high topographic relief, stream order values derived using the synthetic hydrog-raphy were consistent with stream order values determined manually using 1:24,000-scale topographic maps. A program was used to assign stream order values for streams in the synthetic hydrography data set using methods developed by Strahler (1957; fig. 6). The beginning or headwater streams are designated as first-order streams. A second-order stream is formed when two first-order streams intersect; when two second-order streams intersect, a third-order stream is formed; and so forth. The ARC/INFO NEAR command was used to locate the stream nearest to a water-quality site and transfer the stream order value to the water-quality site. The derived stream order values were transferred to the environmental characteristic data set (appendix 1, back of report). Figure 4.

Immediate Stream-Channel Slope The immediate stream-channel slope is defined in this report as the change in elevation between beginning and ending points of a stream segment divided by the length of the stream segment. The average length of a stream segment used to com-pute the immediate stream-channel slope was 1.75 miles. The minimum and maximum lengths used were .31 mile and 3.1 miles, respectively. Stream slope varied slightly when checked against slope values determined manually from 1:24,000-scale topographic maps. Basin characteristics such as stream slope can be problem-atic because the length measured is highly dependent on scale or in this case, dependent on the cell threshold used to create synthetic hydrography. Flow-accumulation data sets, and the DEM created by Cederstrand and Rea (1995) were used to cal-culate the immediate stream-channel slope for each of the 798 water-quality sites. The “Drainage-basin areas” section of this report provides specific information about topographic data sets created by Cederstrand and Rea. A vector linear network that represented Oklahoma streams was created from the flow-accumulation data set using the ARC/INFO GRID function STREAMLINE. The flow-accumulation and flow-direction data sets created by Ceder-strand and Rea (1995) were designed specifically for defining watersheds; therefore, the corresponding stream network is very dense and file size is very large. To decrease file size and reduce processing times, the ARC/INFO BUFFER command was used to select only the streams within a 5,000-meter dis-tance from the water-quality sites (fig. 7). This method decreased the number of arcs from 567,727 to 58,794 arcs. The NODEPOINT command was used to create points for each node in the stream data set. A node is defined as the begin-ning or ending point of a line; therefore, any confluence of streams would be represented as a node. A unique identification code for each point was used that linked the points back to 8 Environmental Characteristics and Geographic Information System Applications for the Development of Nutrient Thresh-olds in Oklahoma Streams Figure 7. Method of designating immediate stream-channel slope. Environmental Characteristics and GIS Applications 9 the nodes in the stream data set. The LATTICESPOT com-mand was used to overlay the point data onto the DEM and interpolate an elevation value from the underlying neighboring cells. The elevation values were transferred from the point data set to nodes in the stream data set using the RELATE and MOVE commands. The CALCULATE command was used to compute the change in elevation between nodes, divided by the distance between nodes. This calculation resulted in the immediate stream-channel slope for stream segments near water-quality sites (fig. 7). The NEAR command was used to locate the near-est stream segment for each water-quality site and transfer the slope value to the water-quality data set. The stream slope val-ues were transferred to the environmental characteristic data set (appendix 1, back of report). Land Use Land-use proportions were computed for each of the 798 drainage-basin areas using the ARC/INFO GRID module and land-use information from the National Land Cover Dataset (NLCD) (2000). The NLCD is based on 30-meter Landsat The-matic Mapper (TM) data acquired by the Multi-Resolution Land Characterization (MRLC) Consortium. The base data set for the NLCD project was compiled using leaves-off Landsat TM data, nominal-1992 acquisitions and other ancillary leaves-on LandsatTMdata. The NLCD data set consists of 21 land-use categories (table 1). These land-use categories were aggre-gated to produce a land-use data set that consisted of 11 land-use categories (table 2). Table 1.

The ARC/INFO MASK command was used to clip out land-use information for each drainage basin. This method produced a land-use data set for each drainage area. Land-use proportions within each drainage basin were cal-culated by dividing the number of cells of a given category by the total number of cells in a drainage basin multiplied by 100 to yield the percent land-use. The land-use proportions were appended to the environmental characteristic data set (appendix 1, back of report). Summary The U.S. Environmental Protection Agency (USEPA) has developed nutrient criteria using ecoregions to manage and pro-tect rivers and streams in the United States. Individual states and tribes are encouraged by the U.S. Environmental Protection Agency to modify or improve upon the ecoregion approach. The Oklahoma Water Resources Board (OWRB) has developed a dichotomous process that stratifies or groups streams based on environmental characteristics such as stream order and stream slope; this process is commonly known as the Use Support Assessment Protocols, subchapter 15 (USAP). The OWRB is using nutrient and environmental characteristic thresholds developed from a study conducted in the Netherlands. The U.S. Geological Survey, in cooperation with the OWRB, is provid-ing descriptive statistics of water-quality sampling sites that can be used to modify the USAP to reflect hydrological and ecolog-ical conditions relevant to Oklahoma streams and rivers. Four environmental characteristics -- drainage-basin area, stream slope, stream order, and land-use proportions -- that affect nutri-ent concentrations in Oklahoma streams were compiled using a Geographic Information System and are provided in appendix 1 (back of report). Data sets of flow-direction and flow-accumulation (also referred to as hydrologic derivatives) were used to define drain-age basins for 798 water-quality sites in Oklahoma. The ARC/ INFO GRID module was used to create drainage basins and compute corresponding areas. Individual water-quality sites were used to define a pour point (an outlet for a drainage area) from which a complete or partial drainage basin was created. An automated process was developed that iteratively selected a water-quality site, converted it into a pour point, snapped the pour point to cells of high flow-accumulation, and delineated a drainage basin for that site. Over 400 drainage basins extended beyond the coverage of the flow-accumulation and flow-direc-tion data sets developed by Cederstrand and Rea (1995). The ARC/VIEW GEOPROCESSING extension was used to append drainage partially defined drainage areas to the most detailed digital hydrologic unit maps available for those areas. Stream order was calculated using methods developed by Strahler (1952) and a stream data set created from a hydrologic derivative (flow accumulation) of the U.S. Geological Survey National Elevation Dataset (NED). The stream data set derived from the flow accumulation dataset modeled streams in Okla-homa at a consistent stream density. A program was used to assign stream order values for streams in the synthetic hydrog-raphy data. The beginning or headwater streams are designated as a first-order stream. A second-order stream is formed when two first-order streams intersect; when two second-order streams intersect, a third-order stream is formed; and so forth. Selected References 11 The immediate stream-channel slope for each of the 798 water-quality sites was calculated using flow-accumulation and Digital Elevation Model data sets. A vector linear network that represented streams in Oklahoma at a consistent density was created from the flow-accumulation data set. A point data set was made from each beginning and ending node in the stream data set. A unique identification code was used that linked the point data set to the stream data set. The point data set was used to overlay the DEM and extract elevation information for each point. Elevations for each point were transferred to the nodes in the stream data set using unique identification codes. A simple calculation using the change in elevation between nodes, divided by the distance between nodes, was performed to calcu-late the immediate stream-channel slope for stream segments near water-quality sites. Land-use proportions were computed for each of the 798 drainage-basin areas using the ARC/INFO GRID module and land-use information from the National Land Cover Dataset (NLCD). The NLCD is based on 30-meter Landsat Thematic Mapper (TM) data acquired by the Multi-Resolution Land Characterization (MRLC) Consortium. The base data set for the NLCD project was compiled using leaves-off LandsatTMdata, nominal-1992 acquisitions and other ancillary leaves-on Land-sat TM data. The NLCD data set consists of twenty-one land-use categories. These land-use categories were aggregated to produce a land-use data set that consisted of 11 land-use cate-gories. A land-use data set was compiled for the Arkansas- White-Red River basin. Drainage-basin boundaries were used to select only the land-use information inside the drainage basins. Land-use proportions within each drainage basin were calculated by dividing the number of cells of given category by the total number of cells in a drainage basin multiplied by 100.
