CHAPTER 1 – OVERVIEW
Water is one of Arizona's most important commodities. The importance of water will only grow as
Arizona's population increases. The United States Census Bureau has ranked Arizona the 2nd fastest
growing state after Nevada. Arizona's population as of the 2000 census was 5,130,632. Arizona’s
population is expected to double by 2030 to 10,712,397. This increase will unquestionably place further
demands on Arizona’s water supply.
Groundwater is the primary source for Arizona's water (ADWR, 2006). Surface water, Central Arizona
Project water and effluent from wastewater treatment plants, make up the remaining 45 percent of the
water that Arizona uses. The majority of Arizona’s water is used for agriculture with smaller allotments
being used for municipal and industrial uses (Figure 1).
Figure 1. AZ Water Demand by Source and Type (ADWR, 2006)
WHY MONITOR?
ADEQ monitors lakes, streams and groundwater throughout the state to assess whether the water is safe
to drink, safe to swim in, suitable for irrigation, and adequate to support aquatic life. Monitoring is used to
meet state and federal goals of protecting human health and aquatic life. The Clean Water Act (CWA)
and Arizona Revised Statutes (ARS) 49-225 gives ADEQ the authority to conduct ambient water
monitoring.
The information that the Monitoring Unit in the Water Quality Division at ADEQ gathers is used by other
government agencies such as the U.S. Environmental Protection Agency, Arizona Game and Fish, and
the Arizona Department of Water Resources. The data is also used by land owners, universities,
operators of drinking water systems and the public to make informed management decisions.
Figure 2 illustrates the relationship between water quality monitoring, assessments, Total Maximum Daily
Load (TMDL) development, and the implementation of water quality improvement strategies. Water
quality is monitored and the results are compared against the surface water quality standards. The
results of the assessment are included in the CWA Section 305(b) report, while impaired waters are
placed on the 303(d) list. TMDLs are developed for impaired surface waters on the CWA Section 303(d)
list. The National Pollutant Discharge Elimination System (NPDES) is a permitting program which
addresses point source discharges to surface waters. These permits are written to ensure discharges
meet water quality standards. Arizona received delegation for the NPDES program, known as the
AZPDES program, from EPA in December, 2002. The CWA 319 program addresses nonpoint source
pollution and provides grants for projects to improve water quality.

ADEQ’S MONITORING UNIT
The Arizona Department of Environmental Quality's (ADEQ) Monitoring Unit is responsible for monitoring
the water quality of all of Arizona's groundwater and surface waters, not on tribal lands.
Monitoring Unit staff collects water quality data to assess the biological, chemical, and physical integrity of
Arizona’s rivers and streams. The objectives of the Monitoring Unit are:
 Conduct ongoing monitoring of the waters of the state as required by Arizona Revised Statutes
(A.R.S.) §49-225;
 Characterize the baseline water quality of wadeable, perennial streams;
 Provide credible data for surface water quality assessments, identify impaired waters, and determine
compliance with water quality standards as required by §305(b) of the Clean Water Act;
 Collect bioassessment data on the regional biocriteria reference site network to determine trends in
reference conditions over time and to test indexes of biological integrity; and
 Monitor the State's outstanding waters to determine whether water quality is being maintained and
protected in accordance with Arizona Administrative Code (A.A.C. R18-11-112);
 Monitor the State’s groundwater and reservoirs/lakes.
SURFACE WATER MONITORING IN THE SALT AND VERDE WATERSHEDS
This report focuses on wadeable perennial streams within the Salt River and Verde River Watersheds.
Forty-seven stream sites in the Salt and Verde Watersheds were sampled from July 2007 to June 2008
SALT AND VERDE WATERSHED REPORT FY 2008

(fiscal year 2008). Four quarters of water quality monitoring data were collected for most of the sites.
Benthic macroinvertebrate and habitat data were collected at 36 sites during the spring with a follow-up
sampling event for 18 of the sites during the fall. Geomorphology data was also collected on Arizona
streams to determine stream stability and sediment issues (see chapter 3; Stream Stability and Sediment
Pollution).
The purpose of this report is to summarize the water quality data collected during fiscal year 2008.
Chemical results are presented in Appendix A. Appendix B includes summary statistics for water quality
data. Photos of each site are presented in Appendix C. Macroinvertebrate metric values, IBI scores, and
bioassessment results for warm and cold water streams are included in Appendix D.
AZPDES AND TMDL ISSUES IN THE SALT AND VERDE WATERSHEDS
At the time of the study there were 39 Arizona Pollutant Discharge Elimination System (AZPDES) point
source discharge locations within the Salt and Verde watersheds. The 39 outfalls are covered by the 23
permits. These permits are located in Table 1 and the outfalls are shown in Figure 3 (some permits have
multiple outfalls).

Figure 4. Perennial and Intermittent Reaches in the Salt and Verde Watersheds
The Salt River drains an area of approximately 5,980 square miles and is the largest tributary of the Gila
River (Figure 4). The Salt River headwaters originate in the White Mountains from the confluence of the
White and Black Rivers at 11,400 feet in elevation and flows approximately 140 miles to its confluence
with the Gila River at an elevation of about 900 feet above mean sea level. A series of major reservoirs
make up the dammed portions of the Salt River (Roosevelt, Apache, Canyon, and Saguaro Lakes).
Perennial flows are found at the higher elevations due to winter snow, monsoon storms, and springs and
most intermittent streams are found in the western portion of the watershed (ADWR, 2006).
The Verde River drains an area of approximately 6,188 square miles and traverses a distance of about
140 miles (Figure 4). The Verde River headwaters originate just south of Paulden and flows southeast
into Horseshoe and Bartlett Lakes before joining the Salt River. Many large tributaries contribute to the
Verde River including Sycamore Creek, Oak Creek, Wet Beaver Creek, West Clear Creek, Fossil Creek,
and the East Verde River (ADWR, 2006). The Verde watershed includes the highest peak in Arizona,
Humphrey’s Peak at 3,840 meters (12,600 ft). The lowest elevation in the Verde watershed is at the
confluence of the Verde and the Salt Rivers at 396 meters (1,300 ft). Figure 4 shows the perennial and
intermittent reaches in the Salt and Verde watersheds.

The main sources of perennial flows sampled for the Salt and Verde watersheds were snow melt at 52%
and springs at 35% (Figure 5). The streams in these watersheds flow through a variety of landforms such
as mountain meadows, coarse colluvial deposits, bedrock canyons, and alluvial deposits.
Streams were classified according to Rosgen Level 1 stream classification (Rosgen, 1996). B type
streams were by far the dominant stream type for the selected sample sites (Figure 6). These types of
streams are dominated by riffles, have moderate gradients and are located in narrow valleys (Table 3).

Omernik (1987) divided the continental United States into 104 Level III ecoregions. Three of the Omernik
Level III ecoregions occur in the Salt and Verde study areas: Arizona/New Mexico Mountains,
Arizona/New Mexico Plateau, and Sonoran Basin and Range (Figure 7). The Mountains region, which lies
across almost all of the Salt and Verde watersheds, accounts for the majority of the ecoregion. The region
is characterized by mountainous terrain with pinyon-juniper and oak woodlands at low to mid-elevations
and ponderosa pine forests at high elevations. All perennial streams identified in this study occur in the
Mountains region which ranges in elevation from 1,780 to 2,920 meters (5,840 to 9,580 feet). The
Plateau ecoregion, located in the western portion of our study area, is characterized by desert
vegetations at low elevations, grass and shrublands at mid-elevations, and pinyon-juniper woodlands at
high elevations. The Sonoran Basin and Range ecoregion occurs in a small area of the Salt watershed
and is characterized by scattered low mountains with Palo Verde, cactus shrub, and Saguaro Cactus.

Precipitation in the Salt and Verde watersheds generally increases with altitude and varies widely from
season to season. Precipitation is usually highest during summer months of July and August and peaks
again during winter months with the driest period from April through June.

CHAPTER 2 – MONITORING DESIGN AND METHODS
PROBABILISTIC MONITORING DESIGN
Arizona uses a probabilistic monitoring design to assess wadeable perennial streams in Arizona. A
probabilistic monitoring design allows statistically valid inferences to be made about sites that have not
actually been visited. This report is the first of three that will comprise the second statewide probabilistic
assessment of Arizona. The first was completed by the Arizona Game and Fish Department and USGS
in 2006.
For the statewide assessment, fifty-one sites were selected to be sampled over a three year cycle with 17
sites in each region. The Central Monitoring Region is the first region to be sampled. Splitting the state
into three regions enabled ADEQ to keep this rotating approach and minimize travel time. Figure 8
illustrates which watersheds make up each monitoring region and indicates the years each region is
scheduled to be sampled.
Figure 8. Monitoring Regions
In order to use the probability-based monitoring plan, EPA generated a random sampling site list with
specific coordinates using the R-statistical program. The coordinates were then plotted on ADEQ’s
perennial stream map. The map was modified in 2007 from the original version of an Arizona Game and
Fish Department map from 1993. ADEQ updated the map with new “predicted perennial” reaches based
on the USGS models, which used existing ADEQ flow records to predict the hydrological regime of
ungaged streams in Arizona (Anning, 2009). The map was also modified to exclude stream reaches that
were on Native American land, lake shorelines, canals, or ditches.

Next, the random sites were further evaluated by GIS and field reconnaissance, and categorized as
“target” or “non-target”. GIS and reconnaissance validated the following criteria for the “target” sites:
1) Was the sample site wadeable and perennial?
2) Was the sample site accessible?
3) Was permission granted if the site was on private land?
4) Was sample site on Native American Land?
For the Central Monitoring Region 33 sites were evaluated, of which 20 sites were determined “target”
sites. Of the target sites, however, 3 could not be sampled due to landowner denial or the presence of a
physical barrier. The remaining 17 sites were determined to be target-sites for probabilistic stream
monitoring. The 2008 site evaluation results were added as new attributes to the perennial stream map
for future reference and to further improve the accuracy of selecting “target” monitoring sites.
TARGETED MONITORING DESIGN
A targeted monitoring design was used in conjunction with the probabilistic design. Targeted sites are
selected to address data gaps for reaches identified on the 2004 §305(b) Planning List, to monitor
Arizona's Outstanding Waters and to investigate complaints. Table 4 lists all the targeted sites in this
study.
Data Gaps
Section 305(b) of the Clean Water Act requires ADEQ to conduct a water quality assessment of Arizona’s
surface waters every two years. Current EPA guidance states that each surface water assessed should
be placed in one of five assessment categories that describes its level of attainment. The five categories
are as follows:
1) Surface waters where all designated uses are attaining;
2) Surface waters that are attaining some designated uses but there is insufficient data to assess the
remaining uses;
3) Surface waters with insufficient data to assess any designated use;
4) Surface waters that are not attaining one or more designated uses, but a Total Maximum Daily Load
(TMDL) analysis is not required; and
5) Surface waters that are impaired for one or more designated uses and a TMDL is required.
Surface waters with insufficient data to determine whether a surface water is attaining designated uses or
is impaired are identified in categories 2 and 3 on the assessment list. Surface waters in these categories
are included on a planning list and targeted for water quality monitoring to fill existing data gaps. In some
cases, data sets for some sample sites were incomplete and did not include all core parameters required
for §305(b) water quality assessment. In other cases, there were an insufficient number of sampling
events to make an assessment.
Outstanding Arizona Waters
Monitoring Unit (MU) staff collect surface water data for Arizona’s Outstanding Waters (previously
identified as unique waters) to characterize existing water quality and to determine whether water quality
is being maintained and protected. Currently, there are 22 Outstanding Arizona Waters listed in Arizona’s
Administrative Code R18-11-112. The primary purpose of monitoring outstanding waters is to collect data
to characterize baseline water quality. A long-term goal of this program is to acquire enough water quality
data over time to determine water quality trends in Arizona’s outstanding waters and to determine
whether state antidegradation requirements are being met (i.e., water quality is improving, being
maintained, or degrading). Antidegradation rules require that the water quality in Arizona’s Outstanding
Waters not be degraded. MU staff conducted quarterly chemical monitoring and spring
macroinvertebrates collection at sites located on the outstanding waters.
SALT AND VERDE WATERSHED REPORT FY 2008

The following outstanding waters were monitored in the Central Monitoring Region:
 Bear Wallow Creek
 Hay Creek
 North Fork of Bear Wallow Creek
 Snake Creek
 Stinky Creek
�� Oak Creek
 West Fork Oak Creek
Biocriteria
MU staff conducts bioassessments and habitat assessments at biocriteria reference sites, random sites,
and outstanding water sites to develop Arizona’s regional reference site network statewide and to monitor
trends in reference conditions over time. Another purpose of the biocriteria monitoring effort is to test
existing indices of biological integrity for warm and cold water streams over a range of impairment
conditions and sources of stressors. A minimum of 10 biocriteria reference sites are selected in each
watershed each fiscal year (FY). Benthic macroinvertebrate samples are collected in wadeable,
perennial streams with suitable riffle habitats during the spring index period (April, May, or June). Some of
the random sites were also used as reference sites for the FY 08 macroinvertebrate collection. A subset
of the spring sites was also collected during the fall of FY08 for a spring/fall comparison (Appendix D).
Geomorphology
MU staff collect data on stream channel characteristics to determine channel stability and the fate of
sediment transport. Geomorphology sampling is a separate activity from other sampling activities and
sites were selected that had been previously sampled for macroinvertebrates and Stream Ecosystem
Monitoring. The geomorphology analysis was not limited to the Salt and Verde River watersheds but
includes sites sampled over a three year period from 2007 to 2009; twelve sites from the Little Colorado
watershed, eight from the Verde River watershed, and six from the Salt River watershed for a total of
twenty-six sites (see Table 9). The inclusion of non-Salt/Verde sites provides a larger data set that
diminishes the influence of outliers in the data and provides a more accurate trend analysis. Sixteen of
the twenty-six sites are classified as cold water and the remainder as warm water sites. Two of the Verde
watershed sites are classified as intermittent and the remaining sites are perennial.
SITE LOCATION
Table 4 summarizes where the sites were sampled and indicates which monitoring objective was
addressed. Figure 4 shows the aerial location of all the Salt and Verde River monitoring sites.
ADEQ gives each sample site a unique identification code. The first two letters correspond to the
watershed code. For example, SRBON001.69, SR corresponds to the Salt River Watershed. Using
certain rules, the next three letters are chosen to correspond to the stream name. Using our example
SRBON001.69, BON represents Boneyard Creek. Lastly, the values at the end of the identification code
relate to the river miles that pinpoint the sample site on the stream (measured in river miles from the
mouth of the stream to the site location). The site ID SRBON001.69 represents the specific sampling
point 1.69 river miles from the mouth of Boneyard Creek located in the Salt River watershed.

Study Area/Watershed Conditions
During the winter months a large precipitation and flood event occurred in the eastern Verde River
watershed and majority of the Salt River watershed. The flood event ranged in magnitude from an
estimated 3.5 to 30 year return interval in the Salt River watershed and from 2 to 8 year flood event in the
Verde River watershed (Figure 9). Flood return intervals were estimated from statistical summaries for
USGS stream gages in the Salt and Verde watersheds (Appendix D; Pope et al., 1998). The largest flood
events among stream sites were those with a 25 to 30 year return interval in the Salt River watershed
(Campaign Creek, Cherry Creek, Coon Creek, Pinto Creek, West Fork Pinto Creek, and Workman
Creek). The largest flood events in the Verde River watershed were estimated as those with an 8 year
return interval which occurred in the East Verde River, Fossil Creek, Roundtree Creek, Sycamore Creek
and West Clear Creek.

CHAPTER 3 – SUMMARY OF DATA / ANALYSIS
REGIONAL VARIATIONS IN WATER QUALITY PARAMETERS
Water quality parameters can vary significantly by location due to a number of factors such as human
disturbance, geology, ecology and climate. Figures 10 to 17 indicate how parameters, such as discharge,
vary from one site to another. These figures summarize the range and aerial distribution of a particular
parameter. They are not intended to provide pinpoint measurements for each site. Use Appendix A for
specific results.
In figures 10-17, each site is represented as an average of all four quarters. Averaging the data allows
the comparison of many sites and parameters at the same time.
Ranges for each parameter (i.e., the size of each circle and the corresponding range) were chosen based
on criteria such as water quality standards and the distribution of the results. Each parameter is
discussed briefly below.
Discharge. Oak Creek (VROAK048.92) and Wet Beaver Creek (VRWBV012.56) had the highest
discharges in the Central Monitoring Region with values of 179 and 127 cfs respectively. Discharge was
typically lower in the Salt River Watershed (0 to 31 cfs) (Figure 10).
Specific Conductivity (SpCond). Conductivity was markedly lower in the eastern part of the Salt River
watershed near Mount Baldy. All conductivity values in this region were below 133 uS/cm. Pinal Creek
(SRPNL005.12) and Pinto Creek (SRPNT008.48) had the highest average conductivities with values of
1,834 and 1,246 uS/cm, respectively (Figure 11).
Dissolved Oxygen (DO). Stinky Creek (SRSTI000.38) had the lowest average DO for all sites (5.69
mg/L). West Clear Creek (VRWCL036.37) had the highest average DO concentration of 11.08 mg/L.
Most sites had DO concentrations between 8 and 10 mg/L (Figure 12).
E. Coli. The highest average E. coli count was at Wet Beaver Creek VRWBV002.97. The E. Coli values
varied considerably at this site (non-detect - 480 cfu/100 mL). Oak Creek (VROAK002.96), East Verde
River (VREVR045.50), and Spring Creek VRSPN000.78 all had E. coli concentrations over 100 cfu/100
mL. The remainder of the sites had average concentrations below 55 cfu/100mL (Figure 13).
Suspended Sediment Concentration (SSC) and Turbidity. In 2002, ADEQ replaced the water quality
standard for turbidity with suspended sediment concentration (SSC). The SSC standard for the Aquatic
and Wildlife Warm designated use is 80 mg/L, while the Aquatic and Wildlife Cold is 25 mg/L. The
highest SSC and turbidity concentrations were found in the middle of the Verde watershed. The Verde
River (VRVER165.07, VRVER139.99), Oak Creek (VROAK002.96) and Wet Beaver Creek
(VRWBV002.97) all had average turbidity and SSC concentrations greater than 50 NTUs and 28 mg/L,
respectively (Figure 14).
Habitat and Proper Functioning Condition (PFC) Score. Habitat scores provide a qualitative way to
assess riffle habitat quality, riffle extent, riffle embeddedness, sediment deposition and bank stability.
Habitat scores are also used in conjunction with macroinvertebrate sampling to describe the riffle habitat
condition in which the macroinvertebrates were sampled. A score of 0-7 indicates the habitat is very
distressed; 8-14 means distressed, and above 15 is good condition. Proper Functioning Condition (PFC)
is a qualitative method for assessing the condition of riparian-wetland areas (Prichard et al, 1993). The
term PFC is used to describe both the assessment process, and a defined, on-the-ground condition of a
riparian-wetland area. PFC is represented as a percent of the ideal score, which is calculated at the
percent of "yes" responses on the Stream Ecosystem Monitoring field form. A higher percentage
indicates a higher quality riparian area.
SALT AND VERDE WATERSHED REPORT FY 2008
20
None of the sites sampled had habitat scores below 8. Beaver Creek had the worst habitat and PFC
scores (9 and 12% respectively). Oak Creek (VROAK031.38), Sycamore Creek (VRSYW001.72) and
Tonto Creek (SRTON059.43) had excellent habitat and PFC scores equaling 20 and greater than 84%
respectively. Seventy-four percent of the sites had habitat scores in the "good" range (Figure 15).
Percent Fines. Percent fines is the amount of sediment less than 2 mm in size on the streambed. For
cold water streams, percent fines is measured within riffle habitats by measuring a minimum of 100
particles. A result above 30 percent fines is considered to be detrimental to aquatic life in cold water
streams.
For warm water streams, percent fines is determined within reach habitats by measuring a minimum of
100 particles. A result above 50 percent fines is considered to be detrimental to aquatic life in warm
water streams. None of the warm or cold water sites had average percent fines over the narrative
standards. The maximum reach/warm water value was 44 % while the maximum riffle/coldwater value
was 22 %, which are below the 50 % and 30 % limits, respectively (Figure 16).
Index of Biological Integrity (IBI). Seven metrics were used to calculate a macroinvertebrate IBI for
cold water streams: total taxa, Diptera taxa, intolerant taxa, Hilsenhoff Biotic Index, percent Plecoptera,
percent scrapers, and scraper taxa. Table 5 describes the thresholds for IBI scores in warm and cold
water streams.
Sites with inconclusive IBI scores require a verification sample to re-assess the condition of the site. If
the verification sample results are in the ‘poor’ or ‘inconclusive’ ranges, the site is considered to be
exceeding the aquatic and wildlife standard. During the spring index period, 42 percent of the 36 sites
were violating the biocriteria standards (Figure 17). A subset of these sites (n=18) were sampled again in
the fall and only 6 percent continued to violate the standard. More information regarding biocriteria
monitoring and results, see the Bioassessment Results section in Chapter 3.

BIOLOGICAL AND HABITAT ASSESSMENTS
Background
ADEQ utilizes benthic macroinvertebrate to directly assess the aquatic life designated use in wadeable
perennial streams. In 2009, Arizona developed a narrative standard for macroinvertebrates. This
standard is for warm and cold water streams throughout the state (Table 5). The cold water Index of
Biological Integrity (IBI) is based on seven different metrics (total taxa, Diptera taxa, intolerant taxa,
Hilsenhoff Biotic Index, percent Plecoptera, percent scrappers, and scrapper taxa). The warm water IBI is
based on nine metrics (total taxa, Hilsenhoff Biotic Index, Ephemeroptera taxa, Tricoptera taxa,
Chironomidae taxa, percent Ephemeroptera, percent individuals in the dominant taxon, number of
scraper taxa, and percent scrapers). Guidelines for analysis of biological data and use of the biocriteria
standard are presented in the “Narrative Biocriteria Standard Implementation Procedures for Wadeable,
Perennial Streams” (ADEQ, 2008c).
The ADEQ narrative biocriterion reads as follows: “A wadeable, perennial stream shall support and
maintain a community of organisms having a taxa richness, species composition, tolerance and functional
organization comparable to that of a stream with reference conditions in Arizona.” (A.A.C. R18-11-108.01).

Macroinvertebrate Results
The results from water chemistry analysis found few significant ambient water quality issues. The
macroinvertebrate data presents a different view. Fifteen of the 36 sites (42%) violated the
macroinvertebrate IBI during the spring index period from April to June. A subset of these locations (total
of 18 sites) was again sampled in the fall of 2008, for a spring-fall comparison study. Only one of the 18
sites violated the standard in the fall (6%)(Figure 18). The results indicate significantly worse benthic
macroinvertebrate conditions in the spring, most likely due to lasting effects of large winter floods. All of
the assessment results, IBI scores, and metric values are found in Appendix D.
Reference sites should meet the macroinvertebrate IBI score if upstream conditions remain unchanged.
For spring/summer 2008, nearly 43% of reference/outstanding sites were violating the standard or were
inconclusive, indicating there were some anthropogenic or natural disturbance(s) in the area. Large
floods (10 to 50-year events) have been observed in several areas of the watershed in early 2008. These
extreme high flows have undoubtedly scoured the streambeds and banks, impairing in-stream habitat
conditions and reducing the abundance and diversity of the benthic macroinvertebrate population. The
better conditions assessment of the fall is an indication that the macroinvertebrate population in most of
these sites have recovered from the flood impacts well enough to meet the biological standard in as short
as six months.

Figure 18. Overall bioassessment results in spring and fall 2008
Figure 19 summarizes the bioassessment results by different watersheds and by cold vs. warm water
streams. In spring, significantly more sites were violating the biocriterion in the Salt River watershed than
in the Verde River Watershed (although the percentages of both violating and inconclusive categories
combined were similar for the two watersheds). The violating proportion was also greater for the warm
water streams (47%) as compared to the cold water streams (35%), indicating that warm water sites in
the SR watershed were most severely affected by winter floods. In fall, there were no substantial
differences in terms of percentages of attaining sites between the two watersheds or between warm and
cold water streams (all ranging between 80-87% meeting the biocriterion).

Spring IBI scores were highly correlated with flood magnitude in the Salt River sites (Figure 20), but not
so in the Verde River sites. While some IBI scores fall below the 25th percentile for meeting the
biocriteria at sites with flood sizes greater than the 2-year flood event, they are more pronounced at
floods of ≥ 8-year return interval (Figure 20). When floods of high magnitude occur during the winter
months, the biological communities do not always recover during the following season. Although ADEQ
has a sampling criterion of waiting until 4 weeks after a bankfull flood event, it does not currently have a
criterion for sampling post high flood events. Flood events typically scour substrates and eliminate 80-
100% of the benthic fauna (Gray, 1981). A longer time frame is needed for the channel to return to stable
conditions before macroinvertebrate samples can be considered representative of “normal” conditions.
Further research should be conducted to determine a critical flood return interval to use as a biocriteria
sampling criterion.

ADEQ examined whether spring IBI scores at different elevations and watershed sizes were affected
differently by the floods. Regression analyses indicated that IBI scores were generally greater at higher
elevations in the Salt River watershed (R2=0.57), but there was no effect of elevation in the Verde
(R2=0.01; Figure 21). This effect was likely due to the fact that precipitation falls as snow at higher
elevations, especially in the Salt River watershed, and is released more gradually into the drainage
network, thereby attenuating flood effects. Watershed size did not have any effect on IBI scores in either
watershed (Salt R, R2=0.006; Verde R, R2=0.29).

A site by site comparison of spring and fall IBI scores between seasons was conducted to examine
differences in biological integrity due to flood conditions. In the spring season, five samples were
meeting, four inconclusive and nine samples were violating biocriteria. In the fall season, 15 samples
were meeting, two were inconclusive, and only one sample was violating the biocriteria. All IBI scores
improved from spring to fall season, except for two sites, Boneyard Creek and Sycamore Creek (Table 6).
Seven of the nine samples in this dataset were not meeting the biocriteria standard in the spring and were
likely affected/stressed by high flood conditions (floods ≥ 5 year return interval) occurring during the winter
season. There were another six samples, in the spring only dataset, which were likely affected by flooding
as well. These flood affected samples should be exempted from formal 305b/303d assessment and listing
due to natural flood conditions. Samples predicted to have been flood affected are flagged in Appendix D.

A Mann-Whitney significance test indicated that there was a significant difference between the 18 sites
that were sampled in the spring and fall of 2008 (Table 7 and Figure 22). The analysis was re-run without
sites having a flood return interval of greater than 5 years (9 sites). The differences between spring and
fall IBI scores were less pronounced, but still significant, which suggests that there are some seasonal
differences in the macroinvertebrate community, beyond the spring flood effects. Further research is
needed to develop a fall IBI score.

Habitat Results
ADEQ investigated whether spring and fall habitat measurements were different by collecting samples
during fall 2008 after several months of base flow conditions. Seven habitat measurements among the 18
paired samples were compared using a Mann-Whitney significance test and box and whisker plots (Table
8 and Figure 23). None of the seven habitat variables were significantly different between seasons (Table
8). According to these results, there were no major channel or substrate or riparian cover changes
between the spring and fall of 2008. Major channel changes likely occurred during winter and early spring
of 2007-08 and conditions stabilized between spring and fall 2008 when there were no large flood events.

Stressors Affecting the Macroinvertebrate Community
Multivariate analyses were conducted to determine which habitat parameters most contributed to
violations of IBI scores in fall and spring datasets. A discriminate function analysis (DFA) was conducted
to determine which flow and habitat parameters most contributed to the 15 failing IBI scores in the Salt
and Verde River watersheds during spring 2008 sample event. Several DFA analyses were run and the
best model DFA test found that flooding, high percent fines in the substrates, embeddedness of the
substrate and abundance of crayfish had the greatest effect on spring macroinvertebrate samples. In the
fall dataset, there was only one site not meeting the biocriteria standard. No floods occurred during the
monsoon period following the high winter floods, so flood magnitude was not used in the fall DFA
analysis. The best DFA model for the fall dataset found that percent canopy cover, Pfankuch channel
stability class, percent riffle habitat, crayfish abundance, PFC score and habitat score contributed most to
the IBI score distribution in the fall. Crayfish are a stressor because all species are exotic/non-native in
Arizona and are destructive to the benthic community. The fall results are weak however, due to the small
sample size (n=18) and the small number of sites failing or inconclusive with regard to the biocriteria
thresholds. There were differences in habitat parameters responsible for the difference of IBI scores in
the fall versus spring. The flood effect (from January 2008 flood) far outweighed the other substrate
condition factors and biological effect due to crayfish abundance, in the spring dataset. The Salt and
Verde stream ecosystems in this study appear to have recovered from floods by the fall of 2008, in which
SALT AND VERDE WATERSHED REPORT FY 2008

other factors such as canopy cover, substrate and stream channel stability and crayfish had more effect
on the macroinvertebrate IBI scores. These factors are what one would expect to influence the
macroinvertebrate community at base flow.
STREAM STABILITY AND SEDIMENT POLLUTION
Point source pollution has been the primary focus of pollution abatement to the nation’s waters and has
achieved substantial success in improving chemical water quality and to a lesser extent the biological
quality of the nation’s surface water resources. Emphasis has now shifted to non-point source pollution
and the physical integrity of waterbodies. Across Arizona, streams and rivers have been particularly
susceptible to this non-point source pollutant due to Arizona’s arid and fragile landscapes.
In the 1998 305(b) Water Quality Assessment Report, the Arizona Department of Environmental Quality
reported that nearly 70% of all water quality limited waterbodies were either directly impaired by turbidity
or experienced turbidity violations during the assessed period from October 1992 through September
1997 (ADEQ, 1998). In ADEQ’s 2006/2008 Water Quality 305(b) Assessment Report, suspended
sediment is identified as a major contributor to stream and lake pollution (ADEQ, 2008a). Turbidity is
indirectly related to sediment deposition and the process that generates both conditions is similar; thus,
high turbidity and suspended sediment readings usually indicate the erosional status in the watershed or
stream channel itself.
Sediment Impacts on Habitat Quality
Field observations for habitat measures related to sediment include ADEQ’s Habitat Assessment, Proper
Functioning Condition (PFC) (Prichard et al, 1993), and Pfankuch Channel Stability Rating (Pfankuch,
1975; ADEQ, 2010). The three habitat measures are strongly auto-correlated and therefore only Habitat
Assessment was used in the following analyses. Direct quantitative measurements used in this analysis
include reachwide pebble counts, percent morphological features (riffles, runs, pools), macroinvertebrate
taxa, Arizona Index of Biological Integrity (IBI) (ADEQ, 2008c), and Relative Bed Stability (RBS)
(Kaufmann et al, 1999).
A positive relationship exists between habitat quality and the total number of macroinvertebrates present
(Figure 24). Habitat Assessment site scores were converted to percent of the ideal (perfect) score.
Percent Ideal Habitat (%IH) is the raw assessed score expressed as a percentage of the maximum score
that could possibly be attained if the channel was in ideal condition. A study reach that is in ideal
equilibrium (reference condition) with its watershed would have a 100% rating for each and would be
expected to have a large number of macroinvertebrate taxa, a balance of riffles, runs, and pools, healthy
riparian, and a sediment regime in balance with the systems hydrology. Linear regression indicates that
46% of the variation in taxa present is due to habitat complexity. Grey squares are Salt/Verde Watershed
sites and green diamonds are Little Colorado River Watershed sites.

In streams where sediment is accumulating, fine particles fill the interstitial spaces between cobbles in
riffles, pools become shallow, runs tend to predominate and macroinvertebrate habitat is reduced. Figure
25 shows a strong positive relationship between the percentage of riffles present in the assessed reach to
total taxa. Linear regression indicates that 60% of the variability in total taxa is due to the increased
presence of riffles in the reach (p = <0.001). This is not surprising since macroinvertebrates were
collected only in riffles; however, the presence of riffles is usually a good indicator of a balanced
ecosystem. Grey squares are Salt/Verde Watershed sites and green diamonds are Little Colorado River
Watershed sites.
Figure 25. Taxa richness as a function of the
percentage of the riffles in the assessed reach
The percentage of cobbles decrease and the percentage of runs increase when pools and riffles fill with
sand, so it is not surprising that there is a strong negative relationship between percent runs and total
taxa (Figure 26, R2 = 0.45).
Figure 26. Taxa richness as a function of the
percent composition of runs in the reach
The insect orders Ephemeroptera (mayflies), Plecoptera (stoneflies), and Tricoptera (caddis flies) are
sensitive to pollution and are collectively referred to as the EPT group. Figure 27 shows a strong positive
relationship between the percent of cobble present in a reach and EPT taxa (R2 = 0.44). Higher
proportions of cobble provide better habitat for the EPT group and as a consequence increase the
number of EPT taxa.

Sediment Imbalance Effects
An abundance of fines in the stream has a cascading downward effect on stream integrity. Fines are
defined as particles less than two millimeters. Figure 32 reveals that as the percent of fines increase in
the reach, the stream moves away from the ideal condition. An ideal habitat has a low percentage of
fines and a stream substrate comprised of a variety of particle sizes with colonization space for
macroinvertebrates. Regression analysis indicates that fines less than 2 mm account for 52 percent of
the variation in habitat quality. A negative relationship exists between percent fines and percent riffles
(Figure 33, R2 = 0.37); a positive relationship between percent fines and percent runs (Figure 34, R2 =
0.24); a negative relationship between percent fines and total taxa (Figure 35, R2 = 0.34); and a negative
relationship between percent fines and number of EPT taxa (Figure 36, R2 = 0.44). Grey squares are
Salt/Verde Watershed sites and green diamonds are Little Colorado River Watershed sites.

Channel Stability
Relative Bed Stability (RBS) is an index of substrate mobility with respect to physical characteristics of the
waterbody. RBS is the ratio of bed substrate size to the mobile or critical diameter at bankfull flow
(USEPA, 2006). Substrates are expected to move a calculable degree for each natural hydrologic and
geomorphic condition. When observed substrate mobility is considerably greater or less than the
predicted, human-induced suspended and bedded sediment stresses are indicated. By comparing the
actual particle sizes observed from a streambed pebble count with the sizes of particles that can be
mobilized at bankfull flow, stream stability can be evaluated quite accurately.
The range of RBS values are from zero to infinity. Streams with RBS values approximately less than 1
(Log10 RBS less than zero) indicate that the bed is unstable because the bed particles are mobilized at
less than sub-bankfull flows. These channels have a high sediment supply and aggrade. With few
exceptions, the occurrence of extremely unstable beds i.e., those with RBS between 0.0001 – 0.01 do not
normally occur unless there is a considerable amount of fine sediment input to the stream. If RBS is
greater than 1.0 (Log10 RBS = 0), the bed is presumed to be fully mobilized only for events larger than
bankfull and the channel is stable. Reference sites generally have RBS values approximately equal to 1.0
to 2.0. RBS values greater than 2 indicate a high transport capacity and incision may be occurring if it has
not already done so. RBS values greater than 3 are high energy streams (steep gradient) with limited
sediment supply which usually indicate that the channel and banks are greatly armored.
Table 9 lists the sampled streams and their RBS and Log10 RBS (LRBS) values. All but four of the
Salt/Verde Watershed sites appear to have unstable channels and two of those four are cold water high
elevation sites. This appears to indicate that, when compared to the Little Colorado River Watershed
streams, low elevation streams are more unstable than high elevation sites. However; this may be an
artifact due to the small sample size.

Channel stability is greatly influenced by the amount of fines being stored in the channel. Figure 37
shows a strong negative relationship between LRBS and percent fines. Regression analysis indicates
that 72% of the variation (p = <0.001) in LRBS is explained by the effect of percent fines. The channel
increases in instability as the percentage of fines increase from zero. If a LRBS score of near zero is
considered the threshold between stability and instability, then channels having fines of approximately
twenty percent probably should be classified as having an unstable channel.
Figure 37 also reveals that there is a fairly equal distribution of cold and warm water sites along the
regression line potentially indicating no difference in the relationship between stable/unstable channels
and elevation.
SALT AND VERDE WATERSHED REPORT FY 2008

Figure 37. Stream stability expressed as LRBS
compared to percent fines less than 2mm
Stepwise multiple regression using seventeen variables identified four as the best predictors of channel
instability: percent fines less than 2 mm, water surface slope, bankfull area and percent canopy density.
A Spearman rank test indicates that the four variables are not correlated with each other. The formula for
the regression line is:
LRBS = 0.897 + (% fines <2mm * -0.025) + (bankfull area * -0.002) + (water surface slope * -10.335) + (%
canopy density * -0.008))
The R square for this relationship is 0.881. Percent fines is the most important (F = 117.771) variable
while, water surface slope is the least important (F = 7.762) variable in the model. The probability values
for percent fines and canopy density are less than 0.001; for bankfull area p = 0.002, and for water
surface slope p = 0.011. The residuals plot (not shown) reveals no heteroscedasticity, meaning there is
no relation between residuals and LRBS. A residual is the unexplained error in the model; it is the
difference between the actual value of LRBS and the predicted value of LRBS. The first order
autocorrelation is -0.090. Unrelated variables will have a theoretical autocorrelation value of zero
indicating the variables are independent of each other. The model, Figure 38, has a very high R square
and low probability values, a lack of heteroscedasticity, and an autocorrelation value near zero indicating
a very robust model. Grey squares are Salt/Verde Watershed sites and green diamonds are Little
Colorado River Watershed.
Figure 38. Multiple regression results of LRBS
plotted against predicted LRBS
The four variables in the regression equation are all negatively associated with LRBS. Therefore, the
major contributing factors of a stream channel moving towards instability follow the evolutionary process
of an increasing percentage of fines less than 2 mm, a channel that widens and shallows, a lessening of
the water surface slope, and a reduction in percent canopy cover.
Stream Stability and Sediment Pollution Conclusions
Morphological heterogeneity contributes to diverse macroinvertebrate communities. An abundance of
fines in a stream channel reduces habitat diversity and impairs biological diversity. Unstable channels, as
measured by relative bed stability, have proportionally large amounts of fines less than 2 mm and a

CHAPTER 4 – EXCEEDANCES
Thirty-two of the 47 sites had at least one exceedance during the FY 2008 sampling season. An
exceedance occurs when a variable does not meet it’s numeric surface water quality standard by either
exceeding a maximum value or by not meeting the variable’s adopted range. The most common variable
not meeting water quality standards was the IBI score (see Chapter 3 – Macroinvertebrate Results).
Some of these violations are likely due to large magnitude floods that occurred in January 2008 (see
Appendix A). Dissolved oxygen was exceeded at 10 of the sample sites and was the second most
common exceedance (Figure 39, Table 10).
