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 Oklahoma 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 threatened by excessive amounts of nutrients, dependant upon a beneficial use designation for each stream. The Use Support

Assessment Protocols, subchapter 15 uses nutrient and environmental characteristic thresholds developed from a study conducted 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 impairment 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 further 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 environmental characteristic thresholds developed in the Netherlands (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 waterquality 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 Oklahoma 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 characteristics -- drainage-basin area, stream order, stream slope, and

land-use proportions -- that affect nutrient concentrations in

Oklahoma streams were compiled using a Geographic Information 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 provides 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, waterproperties, and location data were retrieved for 798 water-quality sites from the U. S. Environmental Protection Agency

STORET database (U.S. Environmental Protection Agency,

2001), the Oklahoma Conservation Commission, and the Oklahoma Water Resources Board. STORET included data collected 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 environmental characteristics included the Arkansas-Red River drainage 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 procedures 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 environmental characteristics and to describe the methods, procedures,

and data sets used to determine the environmental characteristics.

Environmental Characteristics and GIS

Applications

Drainage-basin areas

Drainage-basin areas for 798 water-quality sites in Oklahoma 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. Flowdirection 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 topographic 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 values 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 calculated 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 delineate 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 iteratively selected a water-quality site, converted it into a

pour point, snapped the pour point to cells of high flowaccumulation, and delineated a drainage basin for that

site. The RESELECT command selected a single waterquality 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 waterquality 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 FLOWACCUMULATION functions (Elevation Derivatives for National Applications, 2001). These data sets (hydrologic derivatives of the

NED) are similar to derivatives of the 60-meter DEM developed

by Cederstrand and Rea (1995) used to delineate drainage

basins.

The stream network needs to have a constant stream density and include all upstream headwaters to calculate stream

order. Stream density can be expressed as a measure of closeness 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 topographic 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 convert the raster linear network (flow accumulation) to a vector

linear network (synthetic hydrography) that represented

streams at a consistent density (fig. 5). The synthetic hydrography 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 minimum 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 hydrography 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 hydrography 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 compute 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 problematic 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 calculate 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 flowaccumulation and flow-direction data sets created by Cederstrand 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 distance 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 beginning 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

Environmental Characteristics and GIS Applications 9

the nodes in the stream data set. The LATTICESPOT command 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 nearest stream segment for each water-quality site and transfer the

slope value to the water-quality data set. The stream slope values 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 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 Landsat

TM data, nominal-1992 acquisitions and other ancillary leaveson Landsat TM data. The NLCD data set consists of 21 land-use

categories (table 1). These land-use categories were aggregated to produce a land-use data set that consisted of 11 landuse categories (table 2).

A land-use data set was compiled for the Arkansas-WhiteRed 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 calculated 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 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 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 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 characteristics -- drainage-basin area, stream

slope, stream order, and land-use proportions -- that affect nutrient 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 drainage 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-direction 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 Oklahoma at a consistent stream density. A program was used to

assign stream order values for streams in the synthetic hydrography 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 calculate 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 Landsat TM data,

nominal-1992 acquisitions and other ancillary leaves-on Landsat TM data. The NLCD data set consists of twenty-one landuse categories. These land-use categories were aggregated to

produce a land-use data set that consisted of 11 land-use categories. A land-use data set was compiled for the ArkansasWhite-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.
