1 Background
The Karuk Tribe is the second largest Tribe in California, with over 3,500 Tribal
members currently enrolled. The Karuk Tribe is located along the middle Klamath River
in northern California. Karuk Ancestral Territory covers over 90 miles of the mainstem
Klamath River and numerous tributaries. The Klamath River system is central to the
culture of the Karuk People, as it is a vital component of our religion, traditional
ceremonies, and subsistence activities. Degraded water quality and quantity has resulted
in massive fish kills, increased occurrences of toxic algae, and outbreaks of fish diseases.
Impaired water quality conditions also apply extreme limitations and burdens to our
cultural activities.
The Karuk Tribe’s Department of Natural Resources has been monitoring daily water
quality conditions in the Klamath River since January of 2000 and tributaries to the
Klamath River since 1998. The Karuk Tribe has been collaboratively involved in
maintaining water quality stations along the Klamath River and its tributaries with the
United States Environmental Protection Agency (USEPA), the United States Geological
Survey (USGS), the Yurok Tribe, Oregon State University and PacificCorps. The
following tables summarize waters within the ancestral territory, tribal uses and goals of
these waters, and impairments to these uses and goals (Tables 1-2).

2 Program Purpose
The overarching mission of the Karuk Tribe is to protect, promote, and preserve the
cultural resources, natural resources, and ecological processes upon which the Karuk
People depend. This mission requires the protection and improvement of the quality and
quantity of water upstream and flowing through Karuk Ancestral Territory and Tribal
trust lands.
The Karuk Tribe Water Quality Program (KTWQP) is currently evaluating the overall
condition of water quality on Karuk Ancestral Territory (KAT), monitoring the extent to
which water quality changes over time, and identifying impacts to beneficial uses. Data
the KTWQP collects is indispensable in monitoring water quality conditions within the
Klamath River Basin and providing valuable information to ongoing water quality
management processes. The information produced allows the Karuk Tribe to give
valuable input in land management decisions and demonstrates the Tribe’s commitment
to sound resource management.
The Klamath River in California is listed as an impaired water body under the Clean
Water Act (CWA) Section 303(d) list for temperature, nutrients, dissolved oxygen (DO),
sediment, and microcystin (NCRWQCB, 2009). The mid-Klamath River can have
elevated water temperatures, low dissolved oxygen levels, elevated sediment loads,
loading from organic matter, and high levels of the cyanotoxin, microcystin. These
detrimental conditions are caused by a variety of factors including the presence of Iron
8
Gate and Copco Reservoirs, hydrological modification, agricultural use, timber
harvesting, mining activities, and fire suppression (NCRWQCB, 2009). Some of the
beneficial uses that are important to the Karuk Tribe and impacted by poor water quality
conditions are, cultural use (CUL), subsistence fishing (FISH), cold freshwater habitat
(COLD), recreation (REC-1 and 2), commercial and sport fishing (COMM), shellfish
harvesting (SHELL), rare, threatened, or endangered species (RARE), migration of
aquatic organisms (MIGR), spawning, reproduction, and/or early development (SPWN),
and wildlife habitat (WILD) (NCRWQCB, 2007).
The data that the KTWQP collects is useful to Tribes, state and federal processes, and
restoration efforts to assess current and past water quality conditions in the mid-Klamath
River. For example, the North Coast Regional Water Quality Control Board
(NCRWQCB) has developed a Total Maximum Daily Load (TMDL) for the Klamath
River and has begun implementing TMDL’s in the Scott, Shasta, and Salmon Rivers.
KTWQP data was used in the development of the technical portion of the TMDL’s.
Compliance points for tracking water quality improvements through TMDL
implementation were placed at KTWQP long-term monitoring locations. On February
18, 2010, forty-eight entities signed on to the Klamath Hydroelectric Settlement
Agreement (KHSA) to remove the four lower dams of the Klamath Hydroelectric Project
(KHP). For this agreement, water quality monitoring will occur to establish baseline
water quality conditions before the dams are removed in 2020.
The Karuk Tribe has established water quality standards for waters within KAT. The
details of these standards are outlined in the Karuk Tribe Water Quality Monitoring Plan
(Karuk, 2002).
3 Collaboration and Coordination
The KTWQP has found that the key to a successful water quality program in the Klamath
is to build collaborative relationships and coordinate with other entities in the basin. This
adds credibility to our data sets, builds trust in our monitoring techniques, stretches water
quality dollars by combining and coordinating monitoring efforts whenever feasible, and
increases the Tribe’s ability to conduct research and monitoring in the mid-Klamath. Our
partners include: Yurok Tribe, Klamath Tribes, Hoopa Tribe, Quartz Valley Indian
Community, Resighini Rancheria, Humboldt State University, Oregon State University,
UC Berkeley, U.S. Fish and Wildlife Service, EPA Region IX, North Coast Regional
Water Quality Control Board, State Water Resources Control Board, U.S. Forest Service,
U.S Geological Survey, Humboldt County, Salmon River Restoration Council, Mid
Klamath Watershed Council, Institute for Fisheries Resources, Pacific Coast Federation
of Fishermen’s Associations, and Klamath Riverkeeper.
The KTWQP participates in many collaborative workgroups. We currently attend
meetings, provide constructive feedback, help set research and monitoring priorities,
working in technical subgroups, looking for and providing support for others grant
proposals, and conduct monitoring and research. Some of the workgroups we participate
in include: the Klamath Blue Green Algae Workgroup, State Blue Green Algae
9
Workgroup, Klamath Basin Monitoring Group, Klamath Tribal Water Quality
Workgroup, and the Klamath Fish Health Assessment Team.
4 Karuk Water Quality Program Design
The purpose of the Karuk Tribe’s water quality monitoring program is to evaluate the
quality of water flowing into, through, and out of Karuk Ancestral Territory and Tribal
Trust lands. We have combined the Tribe’s goals with those of our collaborators listed
above to establish a network of monitoring stations. We have established monitoring
stations both within and above KAT. These stations form a longitudinal profile of water
quality conditions along the mid-Klamath River and associated major tributaries.
Figure 1. Overview of the Karuk Tribe’s water quality monitoring locations along
the Klamath River in 2013.
Nutrient grab samples and phytoplankton are collected both in the Klamath River and the
major tributaries, whereas public health monitoring for algal toxins occurs just in the
mainstem (Table 3). In 2013, the KTWQP continued monitoring at the Camp Creek site
in lieu of the Bluff Creek site for winter turbidity monitoring. This change was made to
support monitoring of upcoming work in the Karuk Tribe Restoration Department. The
Orleans (OR), Salmon River (SA), Seiad Valley (SV), Shasta River (SH), and Iron Gate
(IG) continuous water quality monitoring stations are located at USGS gauging stations.
This sampling focuses around the summer base flow (the growing season), which is
generally from May-October. This is when the most water quality impairments stress
10
beneficial uses. However, grab sampling continues throughout the year to help establish
annual baseline load conditions and turbidity monitoring occurs in the winter when
impairments are typically observed.
The frequency at which sampling occurs is dependent on resources and monitoring
objectives. We focus on increasing a parameters collection frequency when the dynamics
are changing at the greatest rate. For example, nutrient and phytoplankton dynamics are
in flux more over the growing season than during the rest of the year. Therefore, grab
samples may be collected approximately bimonthly (2x/month) during the growing
season (May-October) and monthly the remainder of the year. Another example is our
toxic algae and toxin sampling; it is aimed at being able to inform the public of health
threats and is therefore collected at an increased frequency when threats are highest,
August and September (Kann and Corum 2009).

Plan, and the Karuk Tribe Quality Assurance Protocols and Procedures document
(QAPP).
5 Data Interpretation and Management
The Yurok Tribe received a grant under the Environmental Information Exchange Network
Program to develop the Yurok Tribe Environmental Data Storage System (YEDSS). This
system has been shared with the Klamath Basin Tribal Water Quality Workgroup, which the
Karuk Tribe is part of. All sonde and nutrient sampling data will be entered and stored in
YEDSS. YEDSS utilizes user defined flag criteria which are automatically applied to the data
set. This is very useful in Quality Assurance and Quality Control (QA/QC) screening. Data
entries that fall outside excepted ranges are automatically flagged for further analysis. See
example in Figure 2.
Figure 2. Flagging Criteria automatically applied to sonde data.
12
Raw data and data that have under-gone further QA/QC are automatically archived
separately. Metadata associated with each data type are also stored within the system and can
be easily accessed when questions arise. Phytoplankton and algal toxin data will be entered
into Excel spreadsheets that are checked for accuracy by the Project Manager and backed up
onto the KTWQP network, and an external hard drive system that is maintained offsite.
Data is compiled using spreadsheets and YEDDS. Graphical and statistical analyses are used
to assess the current status and trends of monitored water bodies. In addition, comparisons
between sites can also be made. Overall, water quality is evaluated using standards put forth
in the Karuk Tribe’s Water Quality Control Plan and QAPP. Assessment of data also
includes the evaluation of field methodology and data quality. Data collected is then
submitted electronically to EPA via their Water Quality Exchange network (WQX) and made
publicly available. Data may be utilized by other Tribes, agencies, and entities to help direct
water resource management actions.

The associated Water Quality Assessment Report spreadsheet describes current
impairments.
MAINSTEM KLAMATH
The sonde data presented in Figures 3-8 depicts seasonal temperature, dissolved oxygen
and pH trends at mainstem Klamath River monitoring sites.
Temperature:
In 2013, Seiad Valley (SV) and Orleans (OR) monitoring locations had similar
thermographs when comparing daily averages. The Iron Gate (IG) site had less variability
in average temperature fluctuations than SV or OR. Iron Gate also had a lower peak
average temperature during July-August (Figure 3). This trend is further emphasized
when looking at the average temperature over an eight year period from 2006-2013
(Figure 4). The IG site is just downstream of Iron Gate dam (IGD). Water released from
the dam has a moderating effect on water temperature, providing slightly warmer water in
the fall and winter and colder water during summer peak temperatures when compared to
historic conditions and upstream un-impounded tributary contributions. The chronic
average temperature threshold for salmonids adopted by the Tribe, is 15.5ºC (Karuk,
2002). This data supports the designation of impaired water temperature.

Dissolved Oxygen:
Instantaneous dissolved oxygen (DO) levels in 2013 were the highest at the Seiad Valley
(Figure 7) and the daily average DO is greatest at Orleans (Figure 9). Iron Gate dam has a
negative impact on DO levels from mid September through the end of sampling in 2013,
November. DO levels below the dam drop while increasing at all other Karuk mainstem
Klamath sampling locations (Figure 5 - 8). The timing overlaps with fall-run salmonid
14
migration and spawning and is an impairment of the beneficial use. (There is a data gap
in the Orleans data set due to battery failure.)
Eight-year daily averages for DO depict the annual differences between sites are less
extreme in the middle of the summer when water temperatures are the highest (Figures 4
and 5).

Figure 9. Average daily dissolved oxygen levels from 2006-2013 at mainstem
Klamath River sites: below Iron Gate dam (IG), Seiad Valley (SV), and Orleans
(OR).
pH:
Daily average and instantaneous pH trends vary between mainstem sites in 2013 (Figures
10 - 14). SV has the least seasonal variability and has an instantaneous pH diurnal swing
of approximately 0.8 pH units (Figure 12). Of the Klamath mainstem sites, IG has the
most instantaneous exceedances in 2013 to the NCRWQCB Basin Plan water quality
objective for the Klamath River.
Eight-year trend comparison (Figure 14) depicts daily average pH peaking in late July
and August, with daily average pH exceedances above 8.5 at IG from August through
September.
The spike in pH occurs during the peak in river primary productivity and the lowest DO
readings, indicative of water quality impairments associated with photorespiration. (In
2013, all sites have some data gaps due to probe malfunction and battery failure.)

Mainstem Klamath Conclusions from Datasonde Data 2013: Instantaneous dissolved
oxygen and pH data indicate the impacts to water quality due to photorespiration are most
intense at Seiad Valley, but also experienced at all sites to a lesser degree. Temperature
impacts are greatest at Seiad Valley at the beginning of the summer but Orleans is
greatest from August through September; below Iron Gate Dam has the lowest
temperature due to multiple factors associated with the reservoirs and controlled water
release. Water temperature is impacted heavily by ambient air temperature and the
temperature of receiving waters; these could be the controlling factors between Seiad and
Orleans.
TRIBUTARIES
The KTWQP have monitored three major Klamath tributaries just upstream from the
confluence with the Klamath since 2006: the Shasta, Scott, and Salmon Rivers. Each of
the tributaries has similar seasonal water quality trends.
Temperature:
The Shasta River experiences much warmer temperatures in the early spring. This is due,
in part, to ground water influences which tend to moderate water temperature. Compare
this to the very similar temperature conditions in the Scott, which is fed by a mix of
groundwater and snow-melt; and the Salmon, which is a snow-melt dominated system
(Figure 15).
In 2013, all monitored tributaries depict the highest daily average temperatures during
July, followed by a drop in temperature around the first week of August (Figures 15 - 18).
These water temperatures correlate with high ambient air temperatures in July through
early August. Water temperatures in 2013 peaked earlier and were hotter than those seen
in previous years (Figures 16-18).

Dissolved Oxygen:
Daily average dissolved oxygen for 2013 depicts the usual annual trend, Shasta River
with the lowest daily averages, Scott next and the Salmon River the highest daily average
DO. The lowest DO levels occurred in June to August, this is the general trend at all
tributary sites from 2009-2013 (Figures 19 -25). However, 2013 spring-time DO averages
were the lowest in all tributaries than we have seen in the past 5 years of monitoring. This
time period corresponds with the outmigration of Coho salmon from the tributaries.
22
The NCRWQCB Basin Plan establishes water quality objectives for each tributary based
on instantaneous readings. The Scott River did not drop below the water quality objective
of (x>7 mg/L). The Shasta dropped below the DO threshold (x>7 mg/L) between the
June and August (Figure 21). The Salmon River dropped below its threshold (x>9 mg/L)
the longest, between early July through the end of September (Figure 25).

pH:
Daily average pH in 2013 varied between tributary sites (Figure 26) but was an average
year within each site for the past five years daily average comparison graphs for each
tributary (Figures 27, 29 and 31).
The Salmon River pH was just between 7.5 and 8.5 units for most of the season, meeting
the NCRWQCB Bain Plan water quality objective for all three tributaries, 7< x >8.5.
The Scott River exceeded the Basin Plan objective from the end of May through the end
of October (Figure 30). There is a dramatic decrease in the pH in Scott River during the
spring associated with a spring rain and snowmelt event. The Shasta River was between 8
and 9 pH units for the entire sampling season (Figure 28).

Major Tributary Conclusions from Datasonde Data 2013: Water temperature differed
among sites during the beginning of summer more likely due to sub basin hydrology
differences (snow melt vs spring fed) and differed less once in stream flows dropped and
air temperature became the dominant controlling factor. This trend has been recorded
annually for the past five years. Dissolved oxygen levels in the lower Salmon were the
worst recorded among the three major tributaries for 2013, this drop corresponds with the
Salmon’s highest water temperature readings indicating the rivers decreased ability to
hold oxygen with increased water temperature. Dissolved oxygen levels in the lower
Salmon did not meet the Salmon River Basin Plan water quality objective of 9mg/L for a
large portion of the sampling season, July through September. This timeframe
corresponds with large diurnal pH swings indicting photo-respiration was impacting
water quality in 2013. The pH in the Shasta and Scott River were high in 2013 compared
to the Salmon; but average when compared to there own five year trends.
MAINSTEM AND TRIBUTARIES
Nutrients:
Nutrient samples were collected by the KTWQP in 2013 from the mainstem Klamath and
major tributaries.
Total phosphorus (TP) results for 2013 from the mainstem Klamath and major tributaries
depict Iron Gate (IG), Walker Bridge (WA) and Shasta River (SH) as the highest levels
(Figure 35). TP levels decrease at all monitoring sites longitudinally downstream from
IG. The 2007-2013 (Figure 36) data depicts the same trend. The Shasta River had the
highest TP concentration among all sites sampled from 2007-2013, Scott and Salmon
Rivers the lowest.
Total nitrogen (TN) mainstem concentrations were highest at the most upriver sites (IG
and WA) (Figures 37 and 38). TN concentrations increased throughout the season,
31
doubling between May and October in 2013 (Figure 37). The Shasta River had the
highest TN, compared to other major tributaries, which supports the nutrient enrichment

Mainstem and Tributary Nutrient Conclusions: Agricultural land uses in the upper
Klamath Basin and major tributaries of Shasta and Scott Rivers are the majority of
nutrient contributions in the basin. Grab sample results support this land use assessment.
Trends are consistent throughout the six sampling years.
