FORWARD
This basin status report is one of 27 scheduled for
completion in Region X of EPA for the calendar year 1975. The
information presented herein is based upon all of the documented
data available to EPA at the time of the report distribution.
Several of these reports include a minimal amount of infor-
mation which may not be enough to adequately evaluate the water
quality status of the basin. We feel that it is important to dis-
tribute these reports regardless of the availability of data since
the knowledge of a lack of data is also important to the decision
makers.
A report update is scheduled annually, therefore, additional
data made available in 1975 will be included in the next report.
We welcome comments on this report as well as information con-
cerning additional data and/or sources where additional data might
be obtained. Any correspondence can be addressed to Bill Schmidt,
Chief, Water Quality Monitoring Section, 1200 Sixth Avenue, Seattle,
Washington, 98101. Telephone (206) (442-1193).

OVERVIEW
This basin status report encompasses the Lower Columbia River
and its tributaries.
Each section of the report is sub-divided into the following
three parts: 1. Mainstem Columbia River
2. Washington Tributaries
3. Oregon Tributaries
The Washington tributaries are further divided into water quality
segments as defined by the State of Washington Department of Ecology
(DOE) so that DOE personnel can extract the information in a format
compatible with their reports.
The Walla Walla River is given special emphasis In the "Cause
and Effect"1 sect ion of the report since it is an interstate stream.
Much of the data presented in the report is compared to water
quality criteria. The following table gives the reference for the
criteria used.

SUMMARY
Ambient Profile
I. Columbia River @ Bradwood (RM 39.0) and Columbia River
at Clatskanie (RM 53.5F
1. Nitrate + Nitrite (N02+N03) levels during both periods
exceed algal bloom potential levels during the winter and spring
months.
2. Total Phosphorus levels are above algal bloom potential
levels during the majority of the year for both periods examined.
II. Columbia River below Bonneville Dam (146.0)
1. Both nitrogen (NOp+NOq) and total phosphorus levels exceed
potential algal bloom levels of .3 mg/1 and .5 mg/1 respectively
during the winter and spring months of the year. Averaged data
from the period 1972 to 1975 shows greater nutrient levels
than 1968 to 1970 data. Discrepancies can be partly explained
by the higher average river flow occurinq during April of 1972
to T975 period.
III. Cowlitz Columbia Esturary
Cowlitz River
1. Nitrogen (N02+N03) concentrations near the mouth exceed
the algal bloom potential levels from November to March. High
levels occur during high flow which indicates a direct relation-
ship to flow.
2. Total phosphorus levels exceed algal bloom potential
levels sporatlcally throughout the year, with most of those
violations occuring during the summer months. River flow is
low during the summer indicating a potential point source cause.
High ammonia levels during this period also indicates point
source causes.
3. Total coliform concentrations sporatically violate
water quality standards near the mouth.
-------
Coweeman River
1. Dissolved Oxygen concentrations are in violation of
water quality standards during the summer months.
2. Nitrogen (NOg+NC^) concentrations exceed algal bloom
potential levels from November through May. These levels are
associated with high river flow levels.
3. Total phosphorus concentrations are above algal bloom
potential levels sporatically throughout the year.
4. Bacteria concentrations violate the water quality
standards throughout most of the year.
5. Low river flow and dissolved oxygen levels together
with high phosphorus, ammonia and total col i form levels are
indicators of point source causes in the river. The Kelso
municipality which is the largest point source contributor of
BODr and total phosphorus on the river could be the cause of
the problem.
Toutle River
1. During the winter period, NOo+NCU, NH3, and total
phosphorus levels are directly related to river flows based
upon 1971 through 1972 data. This relationship may indicate
a non-point source problem during this time of year.
2. Phosphorus levels are also high in the late summer
periods and exceed algal bloom threshold levels when flow
is low.
3. Total Coliform values violate water quality standards
sporatically during the year.
IV. Lewis
Lewis River
1. Total phsophorus exceeds the level considered necessary
for algal bloom during the period of February through April of
1972. Dissolved ortho phQSJihorus values are above the algal bloom
level during most of the 1972 water year. This station is
approximately one mile below Woodland Washington, however,
it is not known to what extent Woodland contributes to this
problem.
-------
Burnt Bridge Creek
Based upon 1972-1973 data at RM 14.7, the water quality
of Burnt Bridge Creek appears to be severly degraded.
1. Ammonia levels sporadically exceed a level of .2mg/l indicating
organic pollution.
2. NO;? + NO-}, total phosphorus, and dissolved ortho phosphorus
concentrations continually exceed the excepted levels for
potential algal bloom.
3. Total Coliform concentrations continually exceed water
quality standards throughout the entire year.
Kalama River
1. High concentrations of ammonia, nutrients, and bacteria
accompanied high flows during the winter months of 1972-1973
indicating non-point source pollution.
2. Total colifrom populations that violated water quality
standards during the summer months were probably animal orgin.
V. Middle Columbia
White Salmon River
1. Total phosphorus values sporatically exceed the level
considered conducive for algal growth and dissolved ortho
phosphorus concentrations are above algal bloom levels during
the entire year. Thses levels are associated with higher river
flows indicating non-point source relationships.
2. Total coliform levels violate water quality standards
during several months of the year.
Wind River
1. Dissolved ortho phosphorus concentrations are above algal
bloom levels throughout the entire year.
2. Total coliform concentrations sporatically violate
water quality standards.
-------
Kli'ckitat River
1. Total phosphorus concentrations infrequently exceed
algal bloom potential levels, yet dissolved ortho phosphorus
values are well above algal bloom levels during the entire
year.
2. Total coliform values sporatically violate water quality
standards.
VI. Oregon Tributaries
Umatilla River
1. Water temperature is extremely high during the summer
months, reaching 86 F in August.
2. pH values exceed water quality standards during the
summer months indicating aboundant algal productivity.
3. Nitrogen (NO +N03) concentrations are above algal bloom
potential levels throughout the entire year-
4. Both total and dissolved ortho phosphorus concentrations
are extremely high during the whole year. They are above levels
considered conducive for algal blooms.
John Day River
1. pH values exceed water quality standards during the
summer months.
2. Nitrogen (NOo + N03) concentrations sporatically during
the year exceed the level of algal bloom potential.
3. Total and Dissolved ortho phosphorus are above algal bloom
potential levels throughout the entire year.
Deschutes River
1. pH values on the Deschutes violate water quality standards
during the summer.
2. Both total and dissolved ortho ohosohorus concentrations
exceed algal bloom potential levels throughout the year.
-------
Hood River
1. Total phosphorus concentrations are above algal bloom
levels sporatically during the year.
2. Dissolved ortho phosphorus concentrations are above
the level considered conducive for algal growth during the
entire year.
Sandy River
1. Dissolved ortho phosphorus concentrations are above
levels considered conducive for algal growth during the
winter and spring and are right at the levels during spring
and summer.
2. Total coliform levels exceed water quality standards
during a few months of the year.

Cause & Effect
I. Mainstem Columbia
1. Dissolved gas standards of 110% saturation were
exceeded during the high flow period of April through June
of 1975. Some violations occured below all Columbia River
dams, however, the greatest number occured below the
Dalles Dam and in the lower Columbia (measured at about
RM 70).
2. NO^ + NOg concentrations exceed algal bloom potential
levels during the winter months from the Snake River confluences
to the mouth of the Columbia.
3. Total phosphorus levels are above algal bloom potential
levels from November through June throughout the entire river
reach.
4. Dissolved ortho phosphorus concentrations exceed
algal bloom potential levels from November through June.
From July through October, the levels are low indicating
possible algal uptake.
5. Both total and fecal coliform levels increase from
The Dalles Dam to the mouth of the Columbia river. Water
quality standards for total coliform are violated in the
Columbia river below the Willamette river confluence.
II. Walla Walla
Walla Walla River (Washington)
Water quality degradation is significant between RM 38.7
and RM 15.3 based upon 1974 data. Point & non-point, sources
on the Touchet River and Mill Creek greatly effect the
Walla Walla River.
1. Water temperature standards are violated during the
summer months.
2. Low dissolved oxygen values occur at the lower stations.
3. pH values violate the upper limit of the water quality
standard during the summer months. This is an indication of
algal activity at both stations.
-------
0
4. Ammonia levels frequently exceed .2 mg/1 at the lower
station throughout the early part of the year and during the
summer months at the upper stations.
5. Total coliform levels violate water quality standards
throughout the year and fecal coliform levels are extremely
high during most of the year.
Walla Walla River (Oregon)
1. Total nitrate plus nitrite levels are considerably
greater downstream of Milton Freewater than above it whereas
ortho phosphate levels are approximately the same indicating
that groundwater is the probable cause of the difference.
2. Total phosphorus levels above Milton Freewater as
well as at the state line exceed the algal bloom potential
levels.
Touchet River
Water quality in the Touchet river is severely degraded. Samples
taken during 1974 at stations located at RM .5 and 49.6 show
pollution occuring throughout the length of the river from
below Dayton to the mouth.
1. Water temperature near the mouth violate the water
quality standards during the summer months.
2. pH values violate the upper limit water quality
standard during the summer months at river mile 49.6
3. NOo + N03 concentrations are above the algal bloom
potential levels from January through June.
4. Both total phosphorus and dissolved ortho phosphorus
concentrations are well above the level considered conducive
for algal bloom during the entire year.
5. Total coliform values are well above the water quality
standards throughout the entire year.
-------
?ir
I,
Mill Creek
Water quality in Mill Creek is effected by communities of
College Place and Walla Walla. Samples taken at RM 4.0
and RM 10.0 show an increase in pollution resulting from
the two localities.
1. pH values near the mouth violate the upper limit
of the water quality standards from July through October.
No violations occur upstream.
2. N0£ + N03 , total phosphorus, and dissolved ortho
phosphorus concentrations greatly exceed the algal bloom
potential levels below these communities, whereas, bloom
levels are exceeded only sporatically at the above stations.
3. Total coliform concentrations at the mouth sporatically
exceed water quality standards. No violations occur at the
upstream stations.

LOWER COLUMBIA BASIN DESCRIPTION
Geographic Setting
The main geographic features of the Lower Columbia area
are the Coastal and Cascade mountain ranges extending north and
south on the western side, the Columbia Plateau in the center,
and The Blue Mountains near the eastern boundary. As a consequence
of these features, topography of the Lower Columbia Basin is
widely varied. The Coast Range contains crest elevations between
460 and 760 meters (1500 and 2500 feet) with peaks over 1220 meters
(4000 feet) whereas in the Cascade Range crest elevations vary from
1520 to 1980 meters (5000 to 6500 feet) with peaks over 3050 meters
(10,000 feet). The central part of the basin is characterized by
moderately undulating topography formed by the Columbia Plateau.
To the east, the Blue Mountains rise to crest elevations between
1220 and 1370 meters (4000 and 4500 feet). Geologically, the basin
is largely underlain by igneous materials with basalt lava flows
being very common. Alluvial deposits frequently are found along
the major river valleys. The Coastal Range rocks are composed
of marine and continental sedimentary material whereas the Cascades
are almost entirely from lava flows.

Demographic Aspects
The Lower Columbia area is strongly oriented to pulp and
paper with dependence on agricultural, chemical textile, lumber
and aluminum industry as well. Approximately one-half million
people inhabit the Lower Columbia River basin. On the order
of one-half of the number live in the larger population centers
of Walla Walla, Pendleton, Bend, The Dalles, Vancouver, Camas
and Longview-Kelso. The remainder is scattered in small communities
throughout the basin.
Development of the Columbia River was only minor prior to
1933. Early use of the river was limited to upstream irrigation
and power generation projects. Most early shipping was confined
to waters below Vancouver, Washington. The Great Depression preceded
federal programs to stimulate economic stability through hydro-
electric projects such as Grand Coulee Dam in the Upper Columbia
River and Bonneville Dam,
Climate
The climate of the Lower Columbia Basin is largely controlled
by maritime air masses moving from the Pacific Ocean to the east.
The orographic effect of the Coast and Cascade Ranges is the pre-
dominant factor in the distribution of precipitation in the western
portions of the basin. Annual precipitation in the Coastal Range
crests averaged from 230 to 500 centimeters (90 to 200 inches).
In the valley between the ranges it drops to 100 to 125 centimeters
-------
(40 to 50 inches) nr less and then increases again up to 80
to 100 inches in the Cascades. East of the Cascades, annual
precipitation may be as low as 23 centimeters (9 inches) in
areas such as the John Day drainage south of the Columbia River.
However the orographic effect of the Blue Mountains is to raise
annual precipitation to 90 to 100 centimeters (35 to 40 inches)
in the area south and east of Pendleton.
Hydro!ogic Framework
The Columbia River basin below Pasco makes a major direction
change as it flows easterly through Pasco and turns to the west
as it proceeds towards the Pacific Ocean along the Oregon border.
The Columbia is joined by the Snake River below Pasco which drains
P
approximately 285,000 km (110,000 sq. mi), compared to a total
Columbia River drainage of about 554,000 km2 (214,000 sq. mi.) at
McNary Dam which is about 40 river miles below Pasco. At the mount,
the Columbia River drains a total area of 671,000 km2 (259,000
Tributaries on the north side of the Columbia between Pasco
and The Dalles drain from a narrow band about 48 km (30 mi.) wide
which extends to the southern boundry of the Yakima River. The
Klickitat and White Salmon Rivers enter below The Dalles and
contain drainage from the eastern Cascade Range north of the Columbia
River. Further inflow on the north is contributed by both the Lewis
and Cowlitz Rivers which drain southwesterly from the Cascade Range.
-3-
-------
The tributaries of the Columbia River below Pasco entering
from the south side drain a much greater area than those of
the north. The three largest are the John Day River, the
Deschutes River and the Willamette River. The John Day River
is the most eastern of the three and drains northwesternly
from the B lue Mountains. The Deschutes River drains the central
part of the state collecting flow from the east side of the
Cascade Range . The
Willamette River extends from the Cascade Range on the east to
the Coast Range on the west. It drains from approximately
240 km (150 mi.) south of the Columbia River and contains about
28,500 km2 (11,000 sq. mi.). The Willamette River will be
examined exlusively in another report.
Several dams interrupt the natural flow of the Columbia River.
Bonneville Dam is the farthest downstream at river mile 145.
McNary Dam, at river mile 292, was begun in 1947 and is the
farthest upsteam below Pasco. The Dalles Dam was constructed
from 1952 to 1960 and is at river mile 192.5. The last of the
four Lower Columbia River dams constructed by the Corps of Engineers
is John Day Dam, built from 1959 to 1963 and located at river
mile 216. All four dams are basically navigation and run-of-
the-river power projects with only minor storage for flood
control and seasonal flow regulation.
-4-
-------
18
Most rainfall and runoff in the Basin occurs in the winter
months. Winter temperatures are low enough to produce heavy
snowfall and even small glaciers on the higher peaks of the
Cascades. The precipitation and temperature distributions
produce interesting variations in monthly flow patterns in the
basin. In areas west of the Cascades, such as Willamette,
Cowlitz and Lewis basins, the winter precipitation contributes
to runoff more directly than in other basins and results in peak
runoff during November, December and January. In the middle
of Oregon however, snowmelt is a larger factor in producing
runoff and produces peak flows during April, May and June. The
Columbia River displays this type of pattern also, but with an
intermediate peak in February resulting from high rainfall. The
major peak occurs in May and June, mostly as a result of snow-
melt runoff.
The effect of tides is felt from the mouth as far upstream as
Bonneville Dam. During periods of low flow, stage variations of
over three feet are not uncommon at Vancouver, Washington and
flow reversal has been measured near Prescott, Oregon (river
mile 72).

WALLA WALLA RIVER
This section consists of four separate parts. They
are:
1. Walla Walla river in Washington. Data base is from
1974/01/01 to 1974/12/31.
2. Walla Walla river in Oregon. Data base is from
1973/01/01 to 1974/12/01.
3. Touchet river. Data base is from 1974/01/01 to
1974/12/31.
4. Mill Creek. Data base is from 1974/01/01 to
1974/12/31.
The Washington and Oregon portions of the Walla Walla
river cannot be analyized together because of the inadequate
data base in Oregon. Therefore they are presented independently
of one another.
