REGION 10 WATER QUALITY ASSESSMENT
A logical step-by-step approach is needed to identify and abate nonpoint
sources of pollution within Region 10. The first step must be to assess the
magnitude and extent of the nonpoint source problem.
Region 10 has developed a water quality assessment approach which will
assist EPA planners, land agencies, and state and local agencies in identifying
probable nonpoint sources and determining their effects upon the "fishable-
swimmable" aspect of Regional streams.
Generally the approach is to determine the biological, recreational, and
water quality status of Regional streams and to display each status on color
coded STORE! basin maps. This information is to be related to land use and
land ownership (also on basin maps) as well as other factors such as hydro-
modifications, river flows, mining activities, and point source discharges.
All this information is then systematically organized on a summary table
which can be easily used.
This package contains information for one river basin within Region 10.
The package consists of the following:
1. Five slides of the maps used in the evaluation of the basin.
2. A flow chart showing the phased assessment procedure.
3. A summary table for the basin and a detailed description of
information on the table.
4. A basin point source discharge listing by segment number.
5. Specific information for biological and recreational status.
The STORE! basin map is used as the base map for all status evaluations.
Each map is overlayed by a transparency that contains segment basin boundaries
representing drainage areas associated with segments defined by each state
within the Region. These segment boundaries are used as the basis for
assessing water and land Information.

Biological status information is obtained from field biologists represent-
ing state and federal fish and game agencies. Their judgment is based upon a
set of criteria shown on Table 1. The biological status map (slide #1) shows
the results of this assessment.
Recreational status (slide #2) is obtained from field biologists, fish-
ermen, swimmers, and recreational specialists utilizing the criteria identi-
fied in the Table Explanation.
Slide #3 shows the water quality station locations in each segment.
STORE! was used as a basis for all water quality data since most state and
federal agencies and many local agencies and universities store data in Region
10. The number associated with each point on the map references a STORET
printout page number. Data was retrieved utilizing the STORET standards
flagging program with EPA's Water Quality Criteria as the threshold levels.
Selected water quality threshold and violation screening criteria are shown
and defined in the Table Explanation.
Slides /M and //5 show land use and land ownership throughout the STORET
basin. The source of this information is from land management agencies.
All the information previously discussed and shown on maps is summarized
on the River Basin tables. Information on these tables is arranged by segment
in an upstream to downstream order beginning at the upper end of each STORET
basin.
The information obtained and compiled using this procedure is general;
however, it indicates probable cause and effect relationships related to land
use and land ownership. The backup information on field tables, STORET print-
outs and maps allows the user to make more detailed evaluations. Specific
information gathering investigations in problem areas would be necessary for
an accurate "cause and effect" picture.

This evaluation process is still evolving and is continually being im-
proved based on field verifications and comments from users. If you have
specific questions on the procedures used in these evaluations, please
contact Bill Schmidt, Chief, Water Surveillance and Investigation Section,
Surveillance and Analysis Division, Region 10 (TelephoneFTS 399-1210).

TABLE EXPLANATION
River:
Segment Number:
Sub-basin Information
Sub-basin: Each "STORET" major river basin is divided into minor river basins based on major
tributaries to the main stream. Each sub-basin is further subdivided into segments.
In the table the segments and sub-basins appear in an upstream to downstream order.
The major river or stream and its tributaries in the segment being classified
are listed.
The reach of the river under consideration, including the hydrologic drainage
area that contributes flow to that reach, is designated by number for the pur-
poses of identification and cross-referencing. This number will generally be
the state assigned alpha-numeric code except where a finer division is necessary
in giving a more accurate description of the area.
The area of the entire segment being described is given in square miles.
Annual average, maximum, and minimum discharge (in cfs) are given for the major
stream or reach in each segment where USGS flow records are available.
The upper and lower river miles of the stream or reach in each segment as well
as the river mile of the confluence with the next lowest order stream is given.
For instance, the Powder River (length 145 miles), which enters the Snake River
at river mile 296, is described under "R.M. Range" as:
2967
145-0
Segment Length: The length, in miles, of the reach of the major stream in each segment is given.

Biological Status:
Agricultural (irrigation diversions or returns), reservoirs, channel realign-
ment, or other changes in the natural flow of the stream under consideration
are identified.
I = Agricultural Modifications
R = Reservoir Modification (Number of reservoirs having a total capacity of
5,000 acre-feet or more)
C = Channel Realignment, Revetments, etc.
0 = Other
Where specific data is available, the numerical extent of the hydromodification
is noted as a number after the letter abbreviation. Where numerical information
is lacking, a qualitative notation of extent is used. A '+' means there is
extensive modification of that type in the segment, no symbol after the letter
means it is present, and no letter means its presence is at most negligible.
Present or active (A) mining operations and past or non-active (N) mining opera-
tions are identified for each segment.
A general description of the present water uses in the segment is given. Pwr -
power; Rec - recreation; Ag - agriculture; F+W - fish and wildlife; Mun - muni-
cipal; M+I - municipal and industrial; Ind - industrial; Nav - navigation.
This is a qualitative assessment of biological conditions in the streams of that
particular segment.
Solid Black - (corresponds to red on map) - water environment is unsuitable for
a healthy biological community.
Diagonal Stripes - (yellow on map) - a questionable or intermittedly unhealthy
environment exists.
Dots - (blue on map) - a good environment exists for the biota.
Blank Space - (green on map) - insufficient data is available for evaluation.
Determination of the biological status was carried out by experienced, knowledg-
able biologists associated with various federal and state agencies who are
familiar with the streams in the river segments. Table 1 outlines the criteria
used for the biological evaluations. Evaluations are limited to major streams.
In general, these include first through second or third order streams for rivers
near the seacoast and first through fourth order for inland streams. A certain
amount of subjective judgment has been used, however, as to whether to include

Recreational Status:
Water Quality Status
(Parametric Coverage):
certain higher order streams. Whether a certain higher order stream falls within
the just mentioned bounds is not in itself justification for inclusion. Its size
and significance are also taken into account.
This is the qualitative assessment of water related recreational use for each
segment. The criteria used for evaluation of recreational status was based on
typical year-round use. Two major categories were considered: (1) contact
recreation (swimming), and (2) non-contact recreation (boating, fishing, and
aesthetics).
Dots - (corresponds to blue on map) - popular areas, few complaints registered,
wide diversity of socio-economic uses in evidence.
Diagonal Stripes - (yellow on map) - part-time use due to water management, sea-
sonal water quality and quantity conditions, seasonal accessibility, etc.
Solid Black - (red on map) - no use in areas where that use should normally exist.
Blank Space - (green on map) - insufficient data for evaluation.
The stream order criteria for inclusion in the evaluation are the same as for
biological status.
An assessment of the water quality data available in each of the segments is given.
All data used in the analysis and evaluation is available in EPA's "STORE!" System.
A group of twelve basic parameters is used in assessing the water quality in each
segment.

For good growth and the general well-being of trout,
salmon, and other species of cold water biota, DO con-
centrations should not be below 6 mg/1 (FWPCA, Water
Quality Criteria, 1968). In addition, state water
quality standards normally require 90% saturation for
dissolved oxygen (Idaho and Oregon).

Environmental Impact and Reference
To prevent fish fatalities by "gas bubble disease" in
which dissolved gases in their circulatory system come
out of solution to form bubbles (emboli) which block
the flow of blood through the capillary vessels (Envi-
ronmental Protection Agency, Quality Criteria for
Water. 1976).
The pH range which is not directly lethal to fish is
5-9. However, the toxicity of several common pollu-
tants is markedly affected by pH changes within this
range, and increasing acidity or alkalinity may make
these poisons more toxic. Therefore, a pH range of
6.5 to 9.0 is desirable to protect freshwater aquatic
life (EPA, Quality Criteria for Water. 1976). In pri-
mary contact recreation waters, the pH should be within
the range of 6.5-8.3 except when due to natural causes
to prevent the possibilities of eye irritations in
humans (FWPCA, Water Quality Criteria, 1968). State
pH standards range from 6.5 to 9.0 for Idaho and 6.5
to 8.5 for Oregon and Washington. In light of the
above information, our criteria have been set at 6.5
to 8.5.
Most state standards have a turbidity standard of "not
to exceed 5 JTU over background or natural conditions".
It is, however, rather ambiguous what "background or
natural conditions" are. Also, this type of standard
does not relate to the fishable/swimmable concept.
Excessive turbidity reduces photosynthesis by aquatic
plant life and damages the spawning grounds of fish and
habitat of aquatic invertebrates. It has been observed
that maximum production in hatchery ponds and reservoirs
occurred where the average turbidity was less than 25

and fishing. In; 21st North Amer. Wildlife Conf. Trans.),

Limited studies made to date indicate that different
species of algae have somewhat different phosphorus
requirements with the range of available phosphorus
usually falling between 0.01 and 0.05 mg/1 as P. At
these levels, when other conditions are favorable,
blooms may be expected. While there is no set rela-
tionship between total and available phosphorus (be-
cause the ratio varies with season, temperature, and
plant growth), the total phosphorus is governing as it
is the reservoir that supplies the available phosphorus.
A desirable guideline for total phosphorus is 0.05 mg/1
as P where streams enter lakes or reservoirs (FWPCA,
Water Quality Criteria, 1968). The other criteria
levels for different units and forms of phosphorus
have been determined by unit conversion and relation-
ships found between the phosphorus forms in Region 10.
The other forms of phosphorus are used as indicators
only when data for total phosphorus is lacking.
Mackenthun cited results indicating that inorganic
nitrogen at 0.30 mg/1 and inorganic phosphorus at
0.01 mg/1, at the start of an active growing season,
subsequently permitted algal blooms (Mackenthun, K.M.,
1965. Nitrogen and phosphorus in water. U.S. Depart-
ment of Health, Education, and Welfare, Public Health
Service.).
The amount of un-ionized ammonia is very much dependent
upon pH, temperature, and concentration of total ammonia.
A maximum level of 0.02 mg/1 as un-ionized ammonia is
recommended to minimize toxicity to freshwater aquatic
life (EPA, Quality Criteria for Water, 1976). Concen-
trations of total ammonia above 0.20 mg/1 as N are indi-
cative of organic pollution (Klein, River Pollution 1.,
Chemical Analysis. 1959).

Environmental Impact and Reference
Total and fecal coliform are microbiological indicators
used to determine or indicate the safety of water for
drinking, swimming, and shellfish harvesting. A fecal
coliform log mean of 200 per 100 ml for bathing waters
and 14 per 100 ml for shellfish harvesting waters is
recommended by Quality Criteria for Water, EPA, 1976.
State standards range from 240 total/50 fecal per 100
ml for primary contact recreation in Idaho, 1000 total
per 100 ml in Oregon for general beneficial use, and
1000 total per 100 ml in Washington for Class B general
recreation. From the above discussion, the suggested
criteria level based on general recreation is 1000 per
100 ml for total coliform and 240 per 100 ml for fecal
coliform.
High levels of dissolved solids are a hazard for irri-
gation water. A maximum level of 500 mg/1 is indicated
for water from which no detrimental effects will usu-
ally be noticed. For domestic water supply, the maxi-
mum level is 250 mg/1 (EPA, Quality Criteria for Water,
1976). A relationship exists betweeen dissolved solids
and conductivity where total dissolved solids = .6 to
.8 times the conductivity.
The following criteria levels are recommended to protect
the freshwater aquatic life (EPA, Quality Criteria for
Water. 1976).

The environmental status per each parameter per segment is found by determining the percentage of samples
that are in violation of the particular threshold level. This percentage is then weighted according to
the annual sample size for each segment as follows:
Status Code Class Percent Violations
Number of Samples/Year/Segment/Parameter
More than 20 11 to 20 4 to 10
Solid Black Not Acceptable 51-100% Viol. 61-100% Viol. 71-100% Viol.
Diagonal Stripes Objectionable 11-50% 21-60% 31-70%
Dots Acceptable 0-10% 0-20% 0-30%
No code at all (blank space) indicates insufficient data for evaluation.
The data used for this evaluation is for the period beginning January 1, 1970 until the date of the report.
For each station, parameters with less than 4 samples per year are not used.
Water Quality Status (Station/Data Statistics)
Number of Stations - Actual number of stations within each segment that had at least one parameter
with 4 or more samples per year.
Number of Samples/Parameter - Number of samples per year for each parameter averaged for all
parameters sampled.
Data Adequacy - This determination was made by evaluating the distribution of stations, amount of
data, and in some cases adequacy of parametric coverage versus known environmental quality problems.
+ denotes adequate data
- denotes indadequate data

The figure in each column represents the percentage of total area within each segment under the
jurisdiction of the noted groups.
4. % Land Use
The figure in each column represents the percentage of total area within each segment that is used for
the various purposes listed.
