Some communities without filtration plants have turbid water in the
distribution system whenever the streams are turbid. Filtration also
reduces the possibility of bacterial contamination of the source being
carried into the distribution system. There are a few facilities that
provide for mineral removal; however, this is the exception and they
are not listed. Individual softeners are used in some areas. In some
parts of the City of Lake Oswego softeners are used at a monthly cost
of about $6.00.

It is expected that all surface water supplies will receive complete
treatment by 1985. Well managed and protected watershed sources may be
excepted. The treatment trends for ground water will show an increase
of the number of facilities that provide chlorination.
G. The Cost of Water
Apparent costs of water vary according to the accounting procedure
of the various agencies; however, several examples are given.
The City of Portland has experienced an increase of costs during the
past eleven years that has essentially doubled the cost of delivered water.
System improvements which benefit the user make up a substantial share of
the increase. Increased source, transmission, and distribution storage
capacity make it possible to provide better service, less danger of summer
rationing and improved fire protection.

Annual Reports

Addition of a complete treatment facility to the existing Portland
system would increase the cost of water approximately $40/MG.
The City of Salem has a system of the same general nature as
Portland, only they have not constructed upstream storage. The cost
per million gallons sold in Salem was $119.59 in 1961 and $119.45 in
1962. In 1954 the cost per million gallons sold was $106.60. New
facility construction and increased operations cost can be identified
as the reason for the increase of about 11%.
The City of Corvallis operates two complete treatment plants.
One of which is located on the Willamette River and used only during
the summer months. The full time plant is located on Marys Peak, west
of Corvallis, and utilizes natural flow and stored water in the Marys
Peak watershed. The total cost of delivered water was $154.50 per
million gallons during the fiscal year ending June 30, 1959. Treatment
costs accounted for $41.00 per MG of the total. At Adair Air Force
Station near Corvallis the total cost of $176.91 per million gallons
during 1960 included full time use of a treatment plant using Willamette
River water.
The City of Eugene operates a complete treatment plant at Hayden
Bridge on the McKenzie River. ,The total cost of water has increased
from $92.30 per million gallons in 1950 to $139 per million gallons
delivered in 1960.
No conclusions may be drawn from this limited data except that
costs are rising and storage of mountain watershed water to avoid
treatment of nearby water may not be the least expensive alternate.

H. Present and Future Use and Supply
Table VI presents present and projected populations as well as average
annual and peak month average water demands for Willamette River Basin
water service areas. Areas having more than one source and distribution
system are treated as a single service area with no attempt being made to
project the individual systems requirements.
H-l. Sub-basin Discussion
1. Upper Portion of the Willamette River Basin
Main Stem Willamette River Sub-basin (1-A)
The major water use area in this sub-basin, the Eugene-Springfield
Urban Area utilizes ground water from the McKenzie and Middle Fork Willamette
River Sub-basins and surface water from the McKenzie River. No major use
of the main stem of the Willamette River for municipal purposes in the
Eugene-Springfield area is foreseen.
The other communities in the sub-basin rely upon ground water to
satisfy their demands. Their future municipal demands will undoubtedly be
satisfied from ground water.
Coast Fork Willamette River Sub-basin (2)
The supply of water within the basin appears to be adequate to
satisfy future demands. The City of Cottage Grove relies upon flow from
several watershed streams and provides flocculation, sedimentation and
disinfection for treatment at the town end of the 23-mile transmission
conduit as well as disinfection at the headworks end. Ground water is
the source for Creswell and will continue as the source.
-------
25
Middle Fork Willamette River Sub-basin (3)
The major water use area within this sub-basin is in the Oakridge
area. There is ample water to satisfy future municipal requirements in
this area.
The community of Lowell takes water from the river in the Dexter
Reregulation Pool through an infiltration gallery. The pool is used
extensively for recreation.
The water supply within the sub-basin is adequate for sub-basin
requirements.
McKenzie River Sub-basin (4)
The supply of water within the sub-basin is adequate to satisfy
foreseeable demands of sub-basin communities. The McKenzie River also
is the primary source for the Eugene-Springfield Urban Area. Approxi-
mately 75% of the annual requirement for the Main Stem Sub-basin service
area is supplied by the Eugene Water and Electric Board from its Hayden
Bridge treatment plant. The existing resource and the existing and pro- -
posed storage will more than satisfy projected requirements in that area.
The need for storage for municipal purposes will depend upon adjudication
of existing water rights and power claims as well as the future water use
policy of the State of Oregon.
Long Tom River Sub-basin (5)
The Long Tom River Sub-basin is not water deficient. However, the
seasonal variation of the streamflow above Fern Ridge Reservoir and the
apparent quality in the reservoir and downstream have delayed development
of adequate water systems in the sub-basin communities.
-------
26
The community area of Venita-Elmira is in need of a water system.
Three alternates are apparent: (1) Install a transmission line to Eugene
and purchase water from the Eugene Water and Electric Board. This has
been contemplated and is presently considered as economically unfeasible.
(2) Purchase storage space in Fern Ridge Reservoir if possible and treat
water from the reservoir for distribution. (3) Construct single-purpose
storage on a watershed stream for low flow period use and a treatment
plant. A complete detailed study of the area by a consulting firm will
be required before any progress toward a public water system may occur.
2. Middle Portion of the Willamette River Basin
Main Stem Willamette River Sub-basin (1-B)
The communities in this sub-basin utilize ground water, tributary
streams, and the Willamette River to satisfy their needs. As previously
stated, the means of satisfying their future requirements is somewhat
dependent upon the results of an adjudication of the Willamette River
and its tributaries. In all cases, there is sufficient water available
on an annual basis, but the streams presently used as sources do not
always have sufficient summer flow to satisfy the needs.
The City of Corvallis, after developing a watershed area on Marys
Peak to its limit of economic feasibility, turned to the Willamette River
as the next source. Water produced from this facility is generally sat-
isfactory, except when the characteristics of the water change faster than
adjustments in treatment techniques may be made. The City of Salem, which
is also on a bank of the Willamette River, chose to take its water from the
North Santiam River through a 20 mile transmission line. Complete
-------
27
treatment has been temporarily avoided by using this source. However,
it is reasonable to assume that it will be required eventually.
The other communities of the sub-basin will satisfy their needs
by storage, long transmission lines, or treatment of available water
as Corvallis and Salem have done. The solution for each community will
depend upon a detailed study near the time of need.
Calapooia River Sub-basin (6)
Upstream storage is the apparent means by which the City of
Brownsville may satisfy their future demands. It has been necessary to
alter the stream bed during summer periods of low flow in order to
provide sufficient water to flood the cities infiltration gallery.
Other development of water supplies within the basin will have to either
utilize ground water or provide storage for use during periods of low
flow. Two areas, Sodaville and Holley, are expected to have public
water systems by 1985.
Santiam River Sub-basin (7)
The area along the North Ssmtiam River should not experience
any water supply problems nor should the City of Salem, which takes water
from the river through an infiltration gallery.
The South Santiam River area may experience difficulty in
supplying future demands from natural flow if all existing water rights
and power claims are utilized. Upstream storage under consideration or
under construction will have storage space which the cities, water companies,
and industries may purchase if existing rights may not be satisfied from
natural flow.
-------
28
Marys River Sub-basin (8)
Present demands of the sub-basin are served from natural flow
of Marys River and from a watershed on Marys Peak developed by the City
of Corvallis. Storage for 100 MG has been built, but this will not
satisfy present peak demands during dry years. The City of Corvallis
has developed an additional source from the Willamette River. Additional
water supply development in the sub-basin will be dependent upon upstream
storage. However, most of the populated area is in the lower portion of
the sub-basin and is convenient to the Willamette River as an alternate
source.
Luckiamute River Sub-basin (9)
Only minor development has occurred within this sub-basin and
no significant increase of municipal and industrial is projected. It is
anticipated that the demands will be satisfied from the Luckiamute River
and tributaries, the Willamette River, and ground water.
Yamhill River Sub-basin (10)
The total water resource of the Yamhill River sub-basin is
adequate to satisfy projected demands, but seasonal deficiencies will
make storage or trans-basin diversion necessary. The largest of the
sub-basin communities, McMinnville, has had storage facilities for some
time in order to satisfy peak summer demands. This city has also had
alternate sources investigated. There are three major alternatives available:
(1) transmission from the Willamette River, (2) single- or multi-purpose
Yamhill Basin storage, or (3) trans-basin diversion from coastal streams.
A final selection will, no doubt, reflect economic feasibility and aesthetic
preference at the time of decision.
-------
29
Other smaller sub-basin communities are faced with the same
problem on a smaller scale. It is probable that participation in
proposed upstream multiple purpose storage projects will provide a
satisfactory solution for them.
Pudding River Sub-basin (11)
Season deficiencies of sub-basin stream flow have accelerated
the consideration for upstream storage. Silverton is the largest
community (4,000 served) that relies primarily upon surface water. The
remainder of the communities rely primarily upon ground water.
Molalla River Sub-basin (12)
There is no storage indicated for municipal and industrial
water supply within this sub-basin.
Clackamas River Sub-basin (13)
It is probable that the Clackamas River will be heavily used
in the future for municipal water supply. A complete analysis of the
resource of this river including adjudication of water rights and power
claims and establishment of base minimum flows should be made. Deter-
mination of development requirements will not be clear nor will
reliability be established until this is done.
The water resource of this sub-basin is adequate to satisfy
projected demands, but future seasonal deficiencies and use conflicts
must be overcome.
-------
30
Tualatin River Sub-basin (14)
The Tualatin River sub-basin relies partially upon water from
other sub-basins for municipal water supply at the present time and it
is expected that a greater demand will be made on out-of-basin sources
in the future. Alternatives available include coastal streams, the
Willamette River, and the Columbia River. A complete evaluation must
be made of the existing sub-basin resource and demands before a plan
may be developed. Tualatin sub-basin communities have endorsed the
USER Tualatin Project which recommended storage in the amounts shown in
the tabulation below.

3. Lower Portion Main Stem Willamette River Sub-basin
This sub-basin is the most densely populated area in the Willamette
River basin and also has the greatest demand for water. The supplies are
many and varied, but the largest single source has been developed by the
-------
31
City of Portland in the Bull Run watershed. The transmission facility
is composed of three conduits about 25 miles long with a total capacity of
225 MGD. There is storage for 23,200 MG within the watershed with plans
for an additional 11,150 MG by 1990. There has also been some planning
for diversion from the Clackamas River sub-basin for future supply. The
natural quality of the water and watershed management practices have
made it possible to provide satisfactory water for distribution after
treatment by simple chlorination only.
Other supplies in this sub-basin include ground water and the
Clackamas River. Complete treatment is required of water from the lower
reaches of the Clackamas River. Alternatives and additional sources include
the Columbia and Willamette Rivers, the Clackamas River, and ground water.
Sandy River Sub-basin (15)
The water resources of this sub-basin are adequate for satisfaction
of projected requirements.
I. Industrial 'Water Supply, Willamette Basin, Oregon
There are no industries that have located in the Willamette
Basin solely because of water quality or quantity in recent years. During
the initial development of the basin industrial sites were picked to take
advantage of water power potential and available supplies for plant
operation. However, the availability of large quantities of good water
has continued to contribute to the industrial growth of the valley.
Industries that are arbitrarily categorized as wet process industries are
those that require large quantities of water in their particular process.
Pulp and paper plants and food processing plants are the major wet process
-------
32
industries within the Willamette River Basin. There are other industries
that rely upon water; however, the amount is not significant on an
individual basis.
The only specific industry for which present and projected water
requirements are stated is the pulp and paper industry. The majority
of the food processing plants rely upon municipal systems for their
supply and their requirement is an integral part of the projected
municipal requirement. Other industries are mentioned, but only to
show their existence and their relationship to the local water supply
situation.
The quality of water used or available for industrial use in the
Willamette Basin may best be described as good. Various users treat
the water according to their needs with the degree of treatment ranging
from none to complete treatment. Boiler feed water is nearly always
conditioned regardless of the source. The most undesirable characteristic
of surface water is fluctuation of chemical and physical parameters.
Sediments transported in surface v/ater fluctuate by season and effect
more of the users than any other physical quality parameter. The expense
incurred in coping with the sediments and silts has not been defined.
Intermittent discharges and accidental spills of strong wastes which
cause a change in chemical quality cause operational problems at
industrial treatment plants. The costs incurred in coping with changing
chemical parameters has not been determined.
The most often stated quality requirement by industry is that the
quality remain constant except for seasonal fluctuation.
-------
33
The quantity of water generally assumed to be readily available would
support virtually unlimited industrial development. However, the actual
available supply for future industrial development is restricted. Water
for industrial purposes may be limited in several ways. Many industrial
water rights are of recent vintage and may be reduced by adjudication of
the rights from a stream or may be reduced during an extreme low flow
season. The State of Oregon may withdraw a portion of the natural flow
of a stream from further appropriation in order to maintain at least a
minimum desirable flow. From the foregoing, it becomes obvious that
legally stored water will, in at least some areas, be the only reliable
surface source for future industrial requirements.
1-1 Sub-basin Discussion
The following discussion of industrial water use in each of the
sub-basins of the Willamette River Basin is directed toward the fore-
seeable future. In no case does this go past the level of development
expected to occur by 1985.
1. Uppe r Wi1lame tte Bas in
Main Stem Upper Willamette River (1-A)
There are no significant withdrawals of water from the
main stem Upper Willamette River for industrial purposes. The two largest
users in the City of Eugene, Eugene Fruit Growers and U. S. Plywood, used
175 and 133 million gallons respectively in 1960. Compared with the total
city system intake from the McKenzie River, the Eugene Fruit Growers used
3.7 percent of the total and U. S. Plywood used 2.8 percent of the total.
Other industrial uses in Eugene include a poultry packing plant, dairies,
creameries, soft drink bottlers, an ice plant, steam plants, custom
canners, and many other small users. The total commercial-industrial water
-------
34
sales in the City of Eugene total about 50 percent of the annual intake,
or nearly 2,250 million gallons annually.
Coast Fork Willamette (2)
The largest industrial water user in the sub-basin is the
Weyerhaeuser Timber Company mill at Cottage Grove. The average intake
is 10 MGD, or 3,650 MG annually. Water is used primarily for steam
production, hydraulic debarking and log pond filling. Other industrial
uses include small saw mills and gravel washing. The existing sub-basin
water supply is adequate in quantity and quality to fulfill projected needs.
Middle Fork Willamette (3)
Pope and Talbot, Inc., located near Oakridge, is the major
industry of this sub-basin. An undetermined amount of water is used
for plant operation in producing lumber, plywood and particle board.
There are other smaller mills in the sub-basin, all of which have an
adequate water supply. The water resources of the sub-basin are
adequate in quantity and quality to satisfy all projected industrial
requirements. A part of the industries in Springfield are supplied with
water from the Pacific Power & Light Company water system. The water
supplied by PP&L is produced from wells near the river which are artifi-
cially recharged with water from the Middle Fork Willamette River. The
amount used by industry from PP&L totals approximately 250 MG annually,
or less than one MGD.
McKenzie River (4)
The McKenzie River is the source of water for the majority of the
industrial supply in the Eugene urban area. Most of the industries are
-------
35
served by city systems or water districts in the Eugene urban area.
About 7 MGD withdrawn by municipal systems from the McKenzie River is
used for commercial-industrial purposes.
The largest and only significant demand by a self-supplied
industry is the Weyerhaeuser Timber Company plant in Springfield. This
plant is used for production of lumber, plywood, pressed wood products
and pulp. Current operations require an average x^ithdrawal of 15 MGD,
of which 10 MGD is required for operation of the pulp plant. The present
capacity of the pulp plant is 400 tons/day and the anticipated 1985
capacity is 800 tons/day. The projected total plant water requirement
is 30 MGD. The company holds a water right for 80 cfs (51 MGD). The
quantity of water available in the basin is adequate to satisfy the
foreseeable requirements of industry.
The quality of water is such that the Weyerhaeuser Company treats
only about 6 MGD with an Accelator at the present time. During periods
of heavy runoff, which results in high turbidity, the solids in the
water cause excessive wear of the hydraulic debarker nozzles. It is
presently economical for the company to buy water from the Rainbow Water
District during this period instead of providing more treatment. Chemically,
the water is always of satisfactory quality.
2. Middle Willamette Basin
Middle Portion Willamette Main Stem (1-B)
The use of water for industrial1 purposes from the middle portion
of the Main Stem Willamette is primarily for pulp and paper manufacturing.
Other uses include food processing, concrete products manufacturing, pressed.
wood products manufacturing, and the manufacture of bitumastic pipe.
-------
36
Additional water is withdrawn from the Willamette River by the
City of Corvallis and the Adair Air Force station which is ultimately used
for industrial purposes. The majority of the water provided by the Air
Force station and the City of Corvallis is for food processing. The
present use in Corvallis by Blue Lake Packers, the major city-supplied
industry, is about 30 MG annually; however, most of this is used between
July and October.
In the vicinity of Albany, there are two major water users,
Western Kraft Corporation and Wah Chang Corporation. Unbleached kraft
liner board is produced at the Western Kraft Corporation plant. Present
process techniques require about 4 MGD to satisfy the requirements for
the ninety ton per day plant. There is no treatment except for the boiler
feed water in order to control scale and corrosion. Their existing water
right is for about 20 MGD. Based upon present State water allocation
policy, the plant apparently will not be hampered by a lack of available
water.
The second major water-using industry near Albany is the Wah Chang
Corporation, manufacturers of rare metals. The output of the plant is
not known. However, the average daily water use is 2.7 MGD, or 100 million
gallons per year. Treatment has been limited to simple chlorination;
however, turbidity is a wintertime problem.
The only other major withdrawal of water from the middle portion
of the Willamette River is by the Spaulding Pulp and Paper Company at
Newberg. The 160 ton per day plant produces unbleached pulp and requires
about 5 MGD for plant operations. Their existing water right will provide
about 13 MGD and is adequate for the foreseeable future.
-------
37
The quality of the water is controlled by filtration, chlorina-
tion, and deionization. Their problems are typical of those normally
found, primarily turbidity resulting from transport of silt and other
floating material and changes in chemical quality. It is also necessary
in this plant to supplant the river supply with City water during the
summer when the river water temperature is higher than desirable for
acid mixing. This amounts to about 0.1 MGD during August and September.
Long Tom River (5)
There is no present or projected significant industrial water
demand in this sub-basin. There are several small sawmills and a clay
products plant within the basin; however, the use of water is minor.
The Long Tom River is not desirable either as a source of water for
industrial purposes or as a receiving stream for large amounts of
industrial wastes, and it is therefore not a likely location for any
significant industrial development.
Calapooia River Basin (6)
There are no present or projected significant industrial uses of
water in this basin. There are a few saw mills; however, their use is
minor. The stream is not suitable for assimilation of large amounts of
industrial wastes and is, therefore, not a likely location for
industrial development.
Santiam River (7)
The Santiam sub-basin is most conveniently split into the South,
North and mainstern sub-areas.
-------
38
Present and programmed storage projects in this sub-basin will
offer adequate opportunity for industries to contract for storage for
future use, if required.
Industrial use of water withdrawn from the South Santiam by
industries occurs in the Lebanon-Sweet Home vicinity. The major industrial
withdrawal is for the Crown Zellerbach plant at Lebanon.
Crown Zellerbach operates a 90 ton per day sulphite process pulp
and paper mill at Lebanon which requires about 7 MGD of water. The water
is withdrawn from a canal which is a diversion from the South Santiam
River above Lebanon. Future expansion of this plant is assumed to be
minimal and the water supply for the foreseeable future is assumed to be
adequate. The ultimate supply available will depend upon adjudication
results and future State water policy.
The next largest user is Cascade Plywood Corporation at Lebanon
which requires about 2 MGD. No shortage is foreseen.
There are other minor uses which are both self-supplied and
supplied by the Sweet Home or Lebanon municipal water systems.
There is no appreciable industrial use of water along the
North Santiam River. However, the Columbia River Paper Division of the
Boise Cascade Corporation diverts water from the North Santiam through
a canal to their Salem Mill.
The Columbia River Paper Division operates a 150 ton per day
sulphite pulp and fine paper mill on the bank of the Willamette River in
Salem. Approximately 16 MGD of water diverted from the North Santiam River
is used daily. The water requires complete treatment prior to use. The
-------
39
paper mill shares in a right for 254 cfs (164 MGD) diversion from the
North Santiam River for power and manufacturing purposes dated 1856 and
subject only to a prior right of 50 cfs for the State Game Commission.
The mill also shares in a 342.6 cfs right from Mill Creek which is subject
to about 230 cfs of prior appropriation, and may not be satisfied during
the summer. It is therefore assumed that sufficient water to meet fore-
seeable needs is available.
A portion of the water diverted by the City of Salem is also
used for industrial purposes. Food processing is the major user with an
annual average of about 1.5 MGD with 5 MGD peaks during the canning
season.
There is no significant present or foreseeable industrial demand
made upon the waters of the Main Stem Santiam River.
Marys River (8)
The only industrial use, existing or foreseen, made of water
from the Marys River is for small saw mills. Any significant increase
in industrial utilization of water within the sub-basin would be
dependent upon either storage or trans-basin diversion.
Luckiamute River (9)
The existing and foreseeable industrial use of water in the
Luckiamute sub-basin is minor. However, any major demands would best
be satisfied from stored water.
Yamhill River (10)
Industrial use of water within the Yamhill sub-basin is presently
limited primarily to a few saw mills, a plywood mill at Willamina and
several industries using city water in McMinnville. No significant
-------
40
industrial supply is available without storage or trans-basin diversion.
No appreciable increase in self-supplied industrial water demand is
projected for the foreseeable future.
Pudding River (11)
There is no present or projected major industrial water
supply demand within the Pudding River sub-basin in the foreseeable
future. The largest single user, Birdseye Frozen Foods at Woodburn,
relies upon ground water for its supply. This company was using about
2 MGD in 1961 and has since increased its use and supply. Ground water
is satisfactory for the foreseeable future as its supply.
Mola1la River (12)
Industrial use of water in this sub-basin is minor and is
presently limited primarily to saw mill type operations. Most of that
used is purchased from the City of Molalla. There is no foreseen
demand for industrial process water in the area. However, any large
demands would most probably have to be satisfied from storage.
3. Lower Main Stem Willamette River
Industrial utilization of water from the Lower Main Stem Willamette
River is primarily for pulp and paper production at Oregon City.
At the Oregon City Fails, Publisher Paper Company operates a mill
of 400 tons per day capacity. The mill requires approximately 30 MGD
for sulphite and ground wood processing. About one-haIf, or 15 MGD,
is given complete treatment at a total cost of about $33 per million
gallons and used as process water. The remaining 15 MGD is used for
non-process purposes such as flumes and the like. An additional quantity
-------
41
of water is used non-consumptively for power generation. The mill's
right to use water in this manner dates prior to 1842 for 822 cfs.
Based on projected expansion and present water policy, the mill should
not experience a water shortage.
Crown Zellerbach operates a 600 ton per day plant at West Linn
which is also at the Oregon City falls across the river from the
Publishers Paper mill. The mill produces newsprint and printing paper
from sulphite and ground wood processes. The water requirements are
met by treating approximately 20 MSD of water from the river. The direct
cost for treatment (chemicals and labor) is about $17.65 per million
gallons.
Other uses of this portion of the basin are individually smaller
in quantity.1 However, they are important to the basic economy. In
some instances, it is more economical to purchase water from a municipal
system for boiler use than to treat river water. Silt also poses
a problem for boiler use in the lower reach of the river. The furthest
downstream right is the Pennsylvania Salt Company's right for 8.90 cfs
near the St. Johns Bridge in Portland.
A tremendous amount of ground water is used for industrial purposes
in the area along the lower reach of the main stem Willamette River.
The uses include heating and cooling, process water in food and kindred
plants, fabricating plants, concrete plants and a host of other uses.
It is impractical to attempt to determine a total, if not impossible,
of the annual withdrawal. In 1959 there were over 500 wells listed in
East Portland. The capacity of these wells was over 82 MGD. The portion
•U. S. Geological Survey, Ground Water of East Portland.
C. M. Hogensen, December 1959.
-------
42
used is unknown. The present State policy has not restricted use in
this area. However, it is reasonable to assume that restriction intended
to maintain the ground water in a sufficient quantity and quality for
beneficial uses will eventually be proposed.
Clackamas River (13)
Only minor use is made of water in the Clackamas River sub-basin
for industrial purposes. Although there is no significant industrial
use projected within the area, water in appreciable quantity would most
probably be available only from storage or trans-basin diversion.
Tualatin River (14)
The effects of a shortage of water for industrial purposes have
been felt in the Tualatin River sub-basin. One food processor moved
to another area for a combination of reasons; the lack of additional
water is alleged to have been one of the reasons.
The existing surface water sources within the sub-basin are
presently appropriated to the limit. Further surface water utilization
is possible only with storage and/or trans-basin diversion. A local
committee stated at an Oregon State Water Resources Board public hearing
that an additional 900 acre-feet will be required annually for food
processing by 1975. It is reasonable to predict that an additional
1,000 acre-feet would be utilized, if available, by 1985. The present
pattern of industrial water use within the sub-basin indicates that the
need will be satisfied by municipal systems.
No major water-using industry is projected for location in the
Tualatin River sub-basin and, therefore, water requirements for that
purpose are not stated.

Lower Columbia River in Portland Vicinity and Sandy River

The largest water user in the area of concern is Reynolds Metals
Company at Troutdale. The plant is supplied by fourteen wells with an
annual available yield of four billion gallons. During 1962, 2.4 billion
gallons of water were used. The plant was not operating at full capacity;
however, the water requirement does not vary directly with production.
The majority of the water, 75-80 percent, is used for fume washing or
scrubbing. The remainder is used for various purposes such as cooling
bearings, casting, clean up, etc.
There are other industrial uses of water in the area. However,
they are individually smaller and are able to satisfy their needs from
public water supplies, ground water, or are close enough to the Columbia
River to consider it as an alternate source. The projected industrial-
ization of the area should not be short of water in the foreseeable
future.

Upper tributary streams of the Coast Fork Willamette River
are utilized by the city. (WR=9.7 MGD). Chlorine is added
at the headworks of the 23 mile transmission conduit in
order to provide service along the conduit. Treatment at
the town end is limited to disinfection, f locculation, and
sedimentation. Additional transmission capacity and
filtration will be required in the future.
Water is obtained from wells. Additional capacity will be
required by 1985 for 0.4 MGD. Wells are the most likely
source. Surface alternates include Coast Fork Willamette
River and small tributary streams and springs.
Water is taken from the Middle Fork Willamette R. through
an infiltration gallery in the Dexter reregulation pool
(surface water right, 0.65 MGD). Increased recreational
use of the river and dam pools may make complete treatment
necessary by 1985. Sufficient flow is present for future
use; additional water right for 0.2 MGD needed by 1985.

There is not a public system at the present; however, one
would be expected prior to 1985. Ground water development
is not probable. Streamflows in the area frequently are
zero during summer months. New single purpose storage or
purchase of water from the C of E Fern Ridge Reservoir are
alternates to purchasing water from the City of Eugene.
A water right for 2 MGD, stream storage for 100 MG, and
treatment for 1.5 MGD will be needed to satisfy projected
1985 requirements if a single purpose development is to
be constructed.
The present source on Muddy Creek tributaries has a 0.23
MGD water right. Further development of the existing source
or treatment of Long Tom River water as an alternate supply
is needed by 1985 in the amount of 0.5 MGD. A total of
2 MGD to satisfy peak demands will be required by 2010.

rights for 3.7 MGD. The existing source and water right
will satisfy projected 1985 demands.
The City of Sweet Home provides complete treatment of water
from the South Santiam River and has surface water rights for
4.9 MGD. The source and rights are adequate for the projected
1985 requirement. About 1.5 MGD additional treatment plant
capacity will be required by 1985.
It is expected that a water system will be in operation in
this area by 1985. Ground water development and rights are
assumed to satisfy the projected 1985 requirements. Develop-
ment should be 0.15 MGD.

Falls City satisfies their present requirements from a 0.65
MGD water right on Teal Creek and from springs. Projected
1985 requirements may be satisfied from the present source
with an additional 0.20 MGD water right.
Amity utilizes springs and a deep well for its water supply
with surface and ground water rights of 0.47 and 0.29 MGD,
respectively. Projected 1985 requirements may be met by
existing sources.
Carlton uses Panther Creek as its water source and has a
0.3 MGD water right. Additional water to satisfy the pro-
jected 1985 demand would require an additional water right
of 0.5 MGD and 90 MG stream storage.
Dayton utilizes wells and springs with surface and ground
water rights of 0.32 and 0.87 MGD, respectively. Existing
sources will satisfy projected 1985 demands.

Existing source is adequate in quantity to supply 1985
projected requirements. Treatment for 0.15 MGD will be
required by 1985.
A ground water supplied system is expected to exist in this
location by 1985. Well capacity of 0.15 MGD is recommended
to supply projected 1985 needs.
The city has combined rights for 1 MGD from springs and a
well. The system only yields 0.1 MGD. Additional well
capacity of 0.3 MGD is recommended to satisfy projected
1985 requirements.
According to a 1960 consultant's report the city has devel-
oped the Haskins Creek source to the economic limit, except
for transmission. The July-October 4-month1s capacity is
described as 435 MG. The projected July-October demand is
400 MG and would be satisfied by the existing source.
Consideration for future expanded requirements has been
directed towards storage and trans-basin diversion from the
Nestucca River, a coastal stream. Consideration is also
being given to the Willamette River as an alternate source.
Storage on the S. Yamhill R. is also an alternate, but not
actively considered. Treatment for 6 MGD is an expected
requirement by 1985.

Sheridan utilizes springs as a water supply. Present reliable
capacity is about 0.4 MGD. Projected 1985 demands exceed the
annual supply of 146 MG by 60 MG. The peak 7-day demand
exceeds the supply by 0.8 MGD. The projected 2010 demand,
281 MG, exceeds the supply by 135 MG annually. Alternate sources
include additional springs, the S. Yamhill R. or tributary
storage. The city has expressed interest in the USBR proposed
Gorge Reservoir. Treatment for 1.5 MGD will be required for
surface water utilization.
Willamina has adequate water rights, 2 MGD, to satisfy the
projected 1985 requirements. One right 0.65 MGD is dated 1909
and would be prior to most rights in the Yamhill River system.

of 2.5 MGD. Projected 1985 requirements may be met from ground
water. Additional development of 1.8 MGD will be required.
An inadequate system which cannot supply summer demands uses
water from a creek. Sufficient water is available to supply the
projected 1985 demands. However, a satisfactory system must
be built.
The city takes water from the Molalla River through an infiltra-
tion gallery with a pumping capacity of 1.3 MGD. The surface
water right is for 4.5 MGD. The source is adequate to satisfy
projected 1985 demands with the addition of treatment for 2.5 MGD.
The Mulino area is served from wells and springs having a combined
capacity of 0.19 MGD. Additional capacity of 0.65 MGD from wells
will be required by 1985 to meet projected demands.

It is assumed that many small water districts will be formed
to supply water to this growing portion of the urban population.
Most all of them will satisfy their 1985 requirements from
ground water. A few of them will undoubtedly connect to
existing systems with adequate water available to satisfy their
requirements. Ground water development of 15 MGD will be
