WATER SUPPLY AND WATER QUALITY CONTROL STUDY
TILLER AND GALESVILLE PROJECTS
UMPQUA RIVER BASIN, OREGON
An investigation defining present and potential water needs
for municipal and industrial (M&I) supply and stream flow needs
for maintenance of water quality in Umpqua River Basin has been
made. A need for additional source development for M&I supply
and for storage for regulation of stream flow for water quality
control is revealed. Future water requirements and quality
projections are based on economic, demographic, and engineering
studies.

I. INTRODUCTION
A. REQUEST AND AUTHORITY
The request for this investigation was made by the U. S. Army
Corps of Engineers, Portland District, Portland, Oregon, in a
letter dated May 25, 1965.
Authority for the investigation is: (1) the Memorandum of
Agreement, dated November 4, 1958, between the Departments of the
Army and Health, Education, and Welfare, relative to the Water
Supply Act of 1958, as amended (43 U.S.C. 390b); and (2) the
Federal Water Pollution Control Act, as amended (33 U.S.C. 466
e£ seq.).
B. PURPOSE AND SCOPE
The purpose of this report is to define the need for and the
value of storage for municipal and industrial water supply and for
water quality control in the Tiller and Galesville projects, cur-
rently under study by the U. S. Army Corps of Engineers.
The study area considered is the Umpqua River Basin, but
particular attention has been given to the service areas and stream
reaches of the South Umpqua, Cow Creek, and the main stem Umpqua
that could be influenced by storage releases from the Tiller or
Galesville sites.
Projections of future waste loads, water quality, and water
use have been developed for 1980, 2000, and 2020, based on the
resource potential of Douglas County, which almost coincides with
the boundaries of the Umpqua Basin. Data used in the evaluation
of flow requirements is taken from the Oregon Coast comprehensive
studies being conducted by the Federal Water Pollution Control
Administration.

II. SUMMARY of Findings and Conclusions
A. SUMMARY OF FINDINGS
1. The Tiller and Galesville multiple-purpose reservoir
projects, proposed by the U. S. Army Corps of Engineers, are
located in the Umpqua River Basin in southwestern Oregon. Both
projects are located in, and will serve, the South Umpqua subbasin
and downstream main stem Umpqua River areas. Project purposes
being considered are flood control, municipal and industrial water
supply, irrigation, fish and wildlife enhancement, water quality
control, recreation, and power generation.
2. The South Umpqua River has a drainage area of 1,780 square
miles and an average annual runoff of about 2.0 million acre-feet.
Critical flow in South Umpqua River near Roseburg on a one-in-ten
year recurrence frequency is 80 cfs, occurring in August and
September. Water quality during times of such flows is detrimental
to use of the South Umpqua for anadromous fishlife and recreation.
Dissolved oxygen concentrations during the summer and early fall
have dropped to 5 mg/1 for periods ranging from several days to
several weeks, and temperatures have averaged 75 F, with maximums
over 80°F.
3. Total population of Douglas County in 1960 was 68,500.
Over two-thirds of the total population (47,000) resided in the
South Umpqua Basin—about 35,000 of whom lived in the Roseburg
service area, the county's largest population center. Future
economic growth in the Umpqua Basin, dependent on forest products
industries and food processing, is expected to occur primarily in
the Roseburg area. Basin population is expected to increase to
85,000 by 1980, to 106,000 by 2000, and to 132,000 by 2020. The
Roseburg service area is projected to contain about 90,000 persons
by 2020.
-------
4. Present municipal and industrial water use is about
11.0 million gallons per day (mgd); over 60 percent of the demand
is in the Roseburg area. Surface water is the primary source and,
with treatment, is of suitable quality for M&I use.
Future M&I demands are projected to be 22, 29 and 46 mgd for
1980, 2000, and 2020, respectively. Future needs are concentrated
in the South Umpqua Basin where, aside from Roseburg and Myrtle
Creek, existing supplies will not meet projected demands.
5. Diversionary uses of stream waters in the Umpqua Basin,
in addition to M&I water supply, are irrigation, mining, and
power generation. Instream uses are the anadromous fishery, resi-
dent fishery, water-contact and streamside recreation. The South
Umpqua has an annual escapement of about 10,000 salmon and steel-
head--less than half the anadromous fish population of the North
Umpqua. Recreational use is intense, particularly on the stretch
of the South Umpqua that meanders through the Roseburg area.
6. Municipal and industrial waste sources in the Umpqua
Basin are spread throughout the South Umpqua region and the Rose-
burg area. Total raw waste production in South Umpqua subbasin
in 1965 was about 37,000 population equivalents (PE), with over
85 percent of the total produced in the Roseburg area. After
treatment, these wastes were discharged to streams of the basin
with a total oxygen demand of 5,900 PE, a reduction in bio-chemical
oxygen demand (BOD) of about 84 percent.
After adequate treatment—which, for design purposes, was
selected to be at least 85 percent reduction of BOD--future
waste loads are expected to increase to a maximum of about
41,500 PE by the year 2000. Increased treatment efficiencies
to about 90 percent BOD removal are expected to maintain this
level through 2020.
-------
B. CONCLUSIONS
1. Municipal and industrial water demands will exceed the
reliable supply at varying times and places throughout the study
period... ,By the end of the study period, an annual draft-on-
storage— from proposed Tiller or Galesville Reservoir of 2,350
acre-feet to yield 7.65 mgd of supplemental supply (July-
September) will be required to meet the 46 mgd demand. About 55
percent of the demand will be in the Roseburg service area where
the North Umpqua supply is expected to meet the demand. First
need for storage will begin about the time of assumed project
completion (1975).
2. The annual value of storage in Tiller or Galesville
Reservoir for M&I water supply is estimated to be $220,900, based
on least-cost single-purpose alternative storage costs amortized
on a 50-year basis at 3.125 percent interest.
3. Minimum DO concentrations of 7 mg/1 must be maintained
the year around in the South Umpqua to protect and enhance the
existing anadromous fish runs. With control of temperature (see
FIGURE VIII-3), as recommended by the fishery agencies, fish will
be migrating, feeding, and spawning in most reaches of the river
throughout the year. With temperature control, anadromous fish
production is expected to be more than four times present pro-
duction.
4. Water quality during low flow periods does not now meet
the above objectives for the South Umpqua River. Computations
utilizing present and projected waste loadings show that by 2000
DO levels may be expected to drop below 3 mg/1 in the months of
August and September, even after wastes have received adequate
treatment.
5. There is an immediate need for an annual draft-on-storage
from Tiller or Galesville Reservoirs of 16,000 acre-feet to pro-
vide a minimum average flow of 190 cfs for control of DO in the
months of July, August, September and October. After adequate
treatment of all wastes, a draft-on-storage of 51,000 acre-feet
will be needed to deliver a minimum flow in South Umpqua below
Roseburg of 340 cfs for this control through the same four criti-
cal months by the year 2000. Waste loads after 2000 are expected
_!/ Annual draft-on-storage is the sum of incremental excesses of
needed releases over inflows during a climatic year (April to
April).
-------
to remain fairly constant, due to increased treatment efficiency;"
therefore, no additional storage requirements are anticipated
through 2020.
6. Temperature enhancement can be accomplished in the South
Umpqua with flows from the Tiller project. To meet fishery
requirements, flow releases from Tiller Reservoir ranging from
1,200 to 1,400 cfs would be required to maintain temperatures of
less than 70 F.
7. Storage releases from Tiller or Galesville Reservoirs for
water quality control would benefit a potential population of
120,000 persons residing along 50-60 miles of South Umpqua River
and would maintain conditions suitable for fishing and other
recreational uses of the river. With control of DO, annual anad-
romous fish spawning can be maintained in numbers upward of 10,000.
Releases for temperature control would increase these numbers to
an estimated 46,000 annually.
8. The benefits derived from flow regulation for water
quality control in the South Umpqua River are both tangible and
intangible and would accrue after an adequate degree of waste
treatment has been provided at all major waste sources. The
riparian owners, downstream water users, and the population of the
surrounding area would be the major recipients of the benefits
of this control. As beneficiaries are widespread throughout Lmpqua
River Basin and the State of Oregon, the cost to provide quality
control regulation in Tiller or Galesville Reservoirs would be
non-reimbursable.
9. The cost of providing flow regulation on a single-purpose
basis is considered to be a reasonable measure of the value of the
widespread quality control benefits. Based on least-cost single-
purpose storage costs in South Umpqua Basin, the minimum value of
the benefit assignable to an annual draft-on-storage of 51,000
acre-feet in Tiller and/or Galesville Reservoirs is $640,000 or
about $12.50 per acre-foot.
10. The value of the water quality benefit associated with
storage releases for temperature control and flow stabilization is
considered equal to the value of the enhanced anadromous fishery.
This value will be calculated by the U. S. Fish and Wildlife
Service.
11. After the project is in operation, a system of water
quality and waste monitoring and stream flow forecasting will be
needed to effectively regulate flow for water quality control.

III. PROJECT DESCRIPTION
A. LOCATION
The Umpqua River Basin, located in southwestern Oregon, drains
an area of 4,560 square miles. The major drainage feature of the
basin is the main stem of the Umpqua River, which extends 111 miles
inland from the Pacific Ocean to the junction of its North and
South Forks. The North Umpqua extends an additional 105 miles to
its headwaters in the Cascade Mountains; the South Umpqua meanders
through the densely populated Roseburg area and extends some 104
miles to the Rogue-Umpqua divide.
The proposed Tiller and Galesville project sites are located
in the South Umpqua drainage, as shown on the foldout location map
(inside back cover). The Tiller Reservoir site is located near
the town of Tiller on the South Umpqua at River Mile 75. Drain-
age area at the site is about 450 square miles. The Galesville
site is located on Cow Creek, a tributary of the South Umpqua,
near Azalea at River Mile 60. Drainage area of the reservoir
is some 76 square miles.
B. PROPOSED PROJECTS
Project purposes include irrigation, flood control, municipal
and industrial water supply, water quality control, fishery en-
hancement, recreation, and power generation.
As proposed by the U. S. Army Corps of Engineers, the Tiller
and Galesville projects will have storage capacities of 545,000
acre-feet and 71,000 acre-feet, respectively, about 11 percent of
the Umpqua Basin's 5.4 million acre-feet annual yield. With this
storage, one-in-ten low flows of 80 cfs in the South Umpqua could
be increased to over 1,000 cfs; low flows in the main stem Umpqua
could be augmented from 730 cfs to almost two thousand cfs. As
discussed in succeeding chapters of this report, such increases
in flow will directly benefit water quality in those streams.
-------
IV. STUDY AREA DESCRIPTION
A. BOUNDARIES
The study area for this report is the Umpqua River Basin;
the boundaries of the basin are nearly coincidental with the
boundaries of Douglas County. (See location map.)
Study emphasis has been placed on the South Umpqua River
drainage and on the main stem of the Umpqua River, since these
areas can be served by the proposed projects, and since they
contain about 70 percent of the study area population.
B. PHYSICAL FEATURES AND CLIMATE
Topographically, the basin is composed of three definable
segments: the coastal range, the central valley, which includes
the South Umpqua Valley, and the Cascades. Most of the basin is
forested (89 percent), with agricultural and other non-forest
areas limited to the valleys of the main tributary streams. There
is a total of some 660,000 acres of farm land, with 150,000 acres
in crops; about 12,000 acres are irrigated.
The climate is generally mild, with warm, dry summers and
cool, wet winters. There is little snow, except in the high
Cascades. Precipitation ranges from an annual total of 28 inches
at Riddle to over 100 inches along the crest of the Coast Range
of mountains. Average length of the growing season is about 200
days in the central valley.
-------
V. WATER RESOURCES of the Study Area
A. SURFACE WATER
1. Water Resource Development
Existing water resources development in the Umpqua Basin is
not extensive, consisting primarily of several hydro-power struc-
tures in the headwaters of the North Umpqua. There are no large
impoundments on the South Umpqua River, Cow Creek, or Calapooya
Creek. Irrigation and water supply developments consist of
pumping stations, with few diversion or ponding structures.
A total of 400,000 acre-feet of surface water rights has been
allocated in the basin; over 82 percent of this is for hydro-
electric power and other non-consumptive uses.
2. Hydrology
The hydrology of the pertinent streams in the Umpqua system
is summarized in TABLE V-l. Figures are based on water records
from 1933 to 1962.

For design pur-
poses, the one-in-ten
recurrence period was
selected to determine
flow requirements and
the resultant need
for storage for water
quality control. The
basis for selection
was protection of the
anadromous fishery
during the critical
summer months. During
the months of July,
August, September,
and October, the one-
in-ten and the one-in-
twenty frequency
flows are similar.

ing the ranges of several key water quality parameters for the

As indicated, organic waste assimilation requirements are not
high enough to cause severe dissolved oxygen (DO) depression. DO
levels in the South Umpqua frequently drop below 7 mg/1, but con-
centrations below 6 mg/1 are uncommon, except during extreme low
flows, when values below 5 mg/1 have been observed.
Temperature is a severe water quality problem in the Umpqua
system, particularly in the South Umpqua drainage. Temperatures
in the South Umpqua and Cow Creek during the months of July and
August average about 75 F, well above the maximum temperatures
recommended for anadromous fish. Maximums have reached 98°F.
Temperatures in the main stem Umpqua average about 70 F.
Bacterial contamination resulting from discharge of inade-
quately disinfected sewage and from land drainage is evident. The
most severe problems occur in the South Umpqua as it passes through
the Roseburg area.
As indicated in the appended data, ranges of pH, hardness,
and total dissolved solids are well within the limits for any
raw water use anticipated in the basin. High sediment concentra-
tions from soil erosion are a seasonal phenomenon associated with
periods of high surface runoff and stream flow.
11
-------
5. Water Quality of Projected Storage Releases
Steep slopes with sediment production ratings at 150-500 mg/1
of particulate matter cause inflows into both Tiller and Galesville
Reservoirs to be turbid and fairly high in nutrients. During
periods of heavy logging, organic matter and nutrients are higher.
According to estimates made by the Oregon Water Resources
Board (OWRB), mass average reservoir temperatures will be highest
in September. Stratification will occur in both reservoirs with
September bottom-to-surface temperatures ranging from 44 to 67 F
in Tiller and from 53 to 74°F in Galesville.
Based on probable nutrient levels and temperature character-
istics, it is reasonable to assume that both reservoirs will
experience heavy algal blooms. These blooms, together with other
settling organics, could eventually cause depletions of DO at
lower levels, due to decay of organic matter and lack of reaera-
tion. For this reason, multiple level outlets should be provided
to permit control of DO in reaches immediately below these struc-
tures.
B. GROUNDWATER
Little information is available on groundwater hydrology in
the Umpqua River Basin. The North Umpqua River has extensive
areas of volcanic pumice, which act as reservoirs, soaking up
large quantities of moisture during the wet season and releasing
it throughout the dry summer months. The relatively high base
flow of the North Umpqua River reflects these conditions. Prima-
rily clay-type soils are found throughout the remaining areas of
the Umpqua Basin; although clay soils are capable of holding more
water than pumice, the water moves into, through, and out of the
clay very slowly. Most winter precipitation runs off as surface
flow, and little water is released during the summer.
Only the Milo Academy relies on groundwater for a community
water supply in the South Umpqua River Basin. A few industries
have developed well supplies, but quantities pumped are small.
12
-------
VI. THE ECONOMY
A. GENERAL
The demand for water for municipal and industrial purposes,
and the amount and character of waste waters resulting from such
uses, are determined largely by the activities associated with a
region's economic base. The purpose of this section is to pre-
sent economic and demographic data to be used as a basis for pro-
jecting the needs for water for municipal and industrial purposes
and for estimating the future amounts and types of waste and land
drainage material that may be expected to occur in the Umpqua River
Basin with the expanded development anticipated in the future.
B. PRESENT
1. Industry and Employment
The economy of Douglas County is very heavily dependent on
harvesting and processing the county's timber resource as shown in
FIGURE VI-1. About 91 per-
cent of all manufacturing
employment in the county
in 1960 was in lumber and
wood products. Agricul-
tural employment is rela-
tively less important in
Douglas County than in
either the State or Na-
tion as a whole. Aside
from timber harvesting
and processing, mining
is the only other major
industry sector in which
Douglas County employ-
ment equals or exceeds
the national average.
The 234 persons employed
in mining in April 1960
represented about the same
percentage of total em-
ployment in Douglas
County as that industry
represented in the Uni-
ted States as a whole.

DISTRIBUTION
13
-------
The U. S. Veterans' Hospital at Roseburg and tourism and recrea-
tion activities provide some employment in service industries;
but, even so, total employment in service industries is well below
the proportion in the State and Nation. This is due to the fact
that Douglas County is within an area for which Portland and Eu-
gene provide numerous services, such as trade, education, and
finance.
2. Population
The total labor force of 24,289 in Douglas County in April
1960 supported a population of 68,458; that is, the ratio of
population to labor force was 2.8 to 1. TABLE VI-1 shows the
allocation of county population among the incorporated places and
non-urban portions of the county. A large part of the population
is concentrated in the narrow valleys near the junction of the
North and South Umpqua Rivers. About 31,000 persons (45 percent
of county total) live within a radius of ten miles from the center
of Roseburg.- Another 10,000 live in other towns along the main
highway and railroad bisecting the county from north to south, and
most of the remaining population is along this central artery,
outside incorporated places but suburban in nature. The only
significant population center outside this central strip is
Reedsport, located on the Umpqua estuary, with a population of
about 3,000. Most of the county is very sparsely settled, with
large areas of virtually uninhabited and mountainous national
forest land.
About 45,000 persons (two-thirds of county total) live in
the portion of the county drained by the South Umpqua River. The
North Umpqua subbasin is more rugged and has a population of only
about 8,000. The main stem of the Umpqua, below the confluence
of the North and South Forks and including such minor tributaries
as Elk Creek and Calapooya Creek, has a population of about 16,000.
21
According to the most recent estimate,— Douglas County popu-
lation increased less than 2,000 from 1960-1964, or about 2.6
percent, compared with an increase of nearly 8 percent for the
State as a whole during the same period.
_!/ This includes the following Census Divisions: Roseburg, East
Roseburg, Lookingglass, Riverdale, Wilbur, Winchester, and a
portion of Melrose.

C. FACTORS INFLUENCING FUTURE GROWTH
The outlook for growth of the Douglas County economy depends
on possibilities for (1) maintaining or increasing the annual tim-
ber harvest and (2) diversifying the economy, either by further
fabrication or greater utilization of the timber harvest, or by
development of new types of resources. It is assumed that the
log cut in Douglas County will decline during the study period to
about 80 percent of the present level. A redistribution of the
use of the resource is expected, with smaller sawmills disappearing
as a result of competitive pressures and output at the larger saw-
mills declining. This will be accompanied by an increase in output
at plywood mills. However, due to increasing productivity per
worker per hour, employment in lumber and wood products is expected
to decline in the future. Therefore, expansion of the economy will
have to come from diversification.
Raw materials are available within Douglas County to support
additional pulp and paper manufacture. The possibility of the
establishment of a new mill at the confluence of the North and
South Umpqua Rivers by 1980 has been considered, but planned ex-
pansion of existing facilities at Gardiner, Coos Bay, Toledo, and
Springfield should take up the available resource. It is assumed,
therefore, that no new pulp and paper operations will be built in
the Umpqua Basin within the planning period.
Other resources exist, but they do not appear to have a poten-
tial for providing large employment. Employment in mining is
expected to remain at about its present level and to continue to
occur primarily in the Riddle area. Increased irrigated acreage
is expected to support a moderate-sized food-processing industry,
located in the Roseburg area, by 1980. Although food-processing
expansion is not expected to provide for large employment in the
future, it will be a major contributor to future waste loads. By
1980, food-processing capacity in the South Umpqua is projected to
increase by about 300 tons per day; further expansion to about
600 tons per day may be expected by 2020.
A moderate-sized meat-processing plant may also be located in
the Roseburg area by 1980. Sheep grazing presently provides a raw
material, but it seems probable that most of the animals will con-
tinue to go to established packing plants outside the county.
Employment in service industries is expected to increase due to
tourist and recreational development.

is based upon the assumption that population in the rural portions
of the county will remain at about the present level or decrease
slightly, that population in the smaller incorporated places will
increase 'at the average for the county, and that the remainder and
largest part of the projected population increase would accrue to
the larger cities, particularly Roseburg.

B. EXISTING SOURCE DEVELOPMENT
Present demands are concentrated in the Roseburg Service Area.
The City of Roseburg obtains its water from the North Umpqua, but
its suburbs utilize the South Umpqua. The four separate water
systems which supply the service area (Roberts Creek, Winston-
Dillard, Tri-City, and Roseburg) provide chemical treatment, fil-
tration, and disinfection because of seasonal turbidity, color
and odor problems, and bacterial contamination. The major portion
of industrial water used in the South Umpqua is supplied through
these four systems. Other communities in the study area obtain
municipal water from individual systems on the South Umpqua, Cow
Creek, or Calapooya Creek. Industrial supplies on the Cow Creek
have been developed by Hanna Nickel Smelting Company and Monroe
Lumber Company.
C. PROJECTED M&I DEMANDS AND STORAGE REQUIREMENTS
The forecast of future demands is based on economic projections
and present consumption rates for the various communities. Per
capita consumption rates average 115 gpd with peak summer demands
of over three times the average use. Average per capita rates are
projected to increase to over 190 gpd by 2020. Future industrial
demands are based on production forecasts with the heaviest users
being food processing and forest products.
Study area demands for M&I water for the years 1980, 2000, and
2020 are projected to total 22.0, 28.8, and 46.0 mgd, respectively.
About 55 percent of this demand will occur in the Roseburg Service
Area. Industrial water demands will constitute about 60 percent of
the projected M&I demand.
TABLE VII-2 shows the projected water demands and the supple-
mental storage requirements needed to meet these needs. Future
demands for M&I water supply in the South Umpqua Basin will neces-
sitate the most supplemental storage. Minimum natural stream flow
of the South Umpqua is fully appropriated (240 cfs of consumptive
rights); and, in fact, is over-appropriated during critical years.
In addition, the Oregon Water Resources Board has established a
minimum flow of 60 cfs at the mouth of the South Umpqua. (The
minimum observed flow of record is 36 cfs.) Limited storage will
be needed on Cow Creek to meet future demands.
20
-------
Supplemental storage requirements for the Roseburg Service
Area are based on the projections for suburban areas. The City's
North Umpqua River supply is considered adequate to meet future
demands for the urban area. However, consideration should be
given to a South Umpqua supply to meet peak demands.

I/ This area will most probably be served from the North Umpqua River. A system study is
underway currently.
21 Pulp and paper not included.
Based on TABLE VII-2, total M&I storage needs applicable for
inclusion in Tiller Reservoir are about 3,100 acre-feet. However,
the Olalla Reservoir project (U. S. Bureau of Reclamation) has an
appropriation of 760 acre-feet of storage for M&I water supply to
supplement the Roberts Creek-Winston-Dillard supplies. When this
is subtracted, a total of 2,350 acre-feet of storage is applicable
for inclusion in the Tiller project. It should be noted, however,
that there is no authority within the study area to contract for
the storage.

VIII. WATER QUALITY CONTROL
A. NEED FOR CONTROL
Water uses requiring controlled water quality include munici-
pal and industrial water supply, resident and anadromous fishery,
and recreation. Although these uses are discussed for the entire
Umpqua Basin, particular emphasis has been given to the uses on the
South Umpqua and Cow Creek, which could be served by the proposed
projects.
1. Municipal and Industrial
As discussed in the preceding chapter, both the existing and
potential water supply sources for municipalities and industries
are the surface waters of the main stem Umpqua, Cow Creek, South
Umpqua, and Calapooya Creek.
2. Fishery
The Umpqua River and tributaries support extensive populations
of anadromous fish, including Chinook and Coho salmon and steelhead
and cutthroat trout. Resident trout also inhabit the river system.
The anadromous fish, which spawn and rear in the basin, contribute
to a large sport fishery along the various tributaries and in the
ocean, as well as to the offshore commercial fishery. Preliminary
figures from a survey conducted by Oregon State University in 1965
give some indication of intensity of the sport fishery in the basin.
In that year, total effort by Oregon residents was estimated to be
about 350,000 fisherman trips. The estimated sport catch was about
97,000 salmon and steelhead and over 200,000 trout. Some of the
salmon caught in the ocean were probably produced in other streams.
In addition to Oregon residents, fishing pressure from out-of-
state tourists is increasing steadily with the completion of access
roads and camping facilities.

-------
Although both streams still have extensive fishery today,
there has been a deterioration of the stream environment in the
basin, and particularly in the South Umpqua, which has reduced
fish populations. The Oregon State Game Commission estimates that
runs have been reduced by over 70 percent from historic populations.
A considerable portion of this reduction can be attributed to deg-
radation of the South Umpqua.
Anadromous fish activities in the South Umpqua are illustrated
in FIGURE VIII-2. In general, summer and fall temperatures and
stream flows in the lower South Umpqua are undesirable for salmonid
species which are using the stream at that time. Low summer stream
flows and high water temperatures restrict the -rearing potential
in the South Umpqua and delay fall Chinook and Coho from entering
the river to spawn. Summer steelhead are not present in the stream
for the same reasons.

With higher flows and resultant lower temperatures, the early
segments of Chinook and Coho salmon runs would migrate and spawn
about one month earlier, and the lower river could be used more
extensively for spawning and rearing. With this stream regimen,
the lower Umpqua River could be used much more extensively for
spawning and rearing.
The present salmonid fishery and projected future populations
with the Tiller project are shown in TABLE VIII-2.

3. Recreation
Recreational use of the Umpqua Basin streams is intense, a
function of established recreational habits. Other than game
fishing, recreational water uses include boating, water-contact
sports, picnicking, and camping. Since each stream has many
points of access, user statistics to show intensity of demand
are only partially available. However, an impressive rise in the
number of visits to State parks in the basin indicates a trend in
water-oriented recreation. Day visits to all State parks have
doubled between 1960 and 1965. Parks providing water activities
show even more spectacular attendance growth.
In addition to State facilities, the South Umpqua is
extensively used by Roseburg residents for picnicking, swimming
and other water-contact recreation. Although several city parks
are located on the lower South Umpqua, the stream is not aestheti-
cally appealing during summer low flow periods. A combination of
low flow, high temperatures, profuse algal growths, and floating
solids damage the recreation potential of the stream.

B. WASTE LOADS
1. Municipal and Industrial
Because of the importance of dissolved oxygen content of water,
both as a measure of pollution and as a requirement for fish life,
municipal and industrial waste loads are expressed in terms of
their oxygen consumption—the biochemical oxygen demand (BOD). This
demand is expressed in terms of population equivalents (FE) for
this report.
Present municipal and industrial waste loadings for the
Umpqua Basin are shown in Appendix B and summarized in TABLE VIII-3
by major loading point.

The South Umpqua receives the major portion of basin wastes,
with loading points concentrated in the Roseburg area. The
Roseburg service area, as defined in Chapter VI, produces over 85
percent of the total basin wastes. Although Sutherlin is currently
discharging to the North Umpqua, it is considered close enough to
the Roseburg area to be included for planning purposes. Wastes
from the coastal communities of Reedsport and Gardiner are not
included because ocean outfalls remove wastes from the sphere of
influence of the Umpqua streams.
There are no major industrial wastes with separate outfalls
in the basin, except for the paper mill at Gardiner which dis-
charges to the ocean. Food processing operations discharge to
municipal systems and are included in the municipal loads listed.
26
-------
Total waste production of the basin, excluding the coastal
communities and industries, is about 37,000 PE. All basin wastes
receive treatment before discharge; over-all reduction of wastes
is about 84 percent, with about 5,900 PE discharged to the water-
course.
Future waste load projections are based on the economic fore-
casts presented in Chapter VI. The following assumptions have
been made: (1) future food processing and other industries in the
Roseburg area will be connected to municipal systems: (2) addi-
tional pulp and paper expansion will be located on the coast; and
(3) municipal and industrial wastes will receive at least 85 per-
cent treatment in 1980 and 2000 and at least 90 percent treatment
by 2020. From these assumptions, projected future waste loads are
shown in TABLE VIII-4. It should be noted that due to assumed
increases in treatment efficiency, 2020 projected loads are less
than those for 2000.

Increases in municipal and industrial waste loads are anti-
cipated to occur primarily in the Roseburg area. Not only is popu-
lation growth centered in this area but large increases in food
processing wastes are forecast. Food processing wastes account
for the large increase in waste loads between 1965 and 1980.

C. WATER QUALITY OBJECTIVES
Water quality control evaluations consider primarily those
water quality and water pollution control problems which can be
improved or maintained by stream flow regulation. For the South
Umpqua and its tributaries, these include dissolved oxygen,
temperature, and nuisance aquatic growths and are associated with
maintenance of fishlife, water recreation, and aesthetic environ-
ment. The benefits associated with water quality control for these
uses are widespread. Water quality objectives have been developed
for the various water uses based on the following indicators.
1. Dissolved Oxygen
The dissolved oxygen (DO) objective for the South Umpqua is
delimited by anadromous fishery requirements—the use requiring
the highest DO level. Other uses served at this level are recrea-
tion and aesthetic conditions. Since salmon and steelhead use the
stream at all times of the year for either spawning, rearing, or
migration, a minimum objective of no less than 7 mg/1 must be main-
tained in the lower South Umpqua throughout the year. DO satura-
tion is required in headwater areas for fish spawning and incubation.
2. Temperature
Temperature requirements for the South Umpqua are also governed
mainly by the anadromous fishery, but recreation and general stream
conditions benefit from cooler
water temperatures. The fol-
lowing illustration (FIGURE
VIII-3) shows the temperature

tures
during July and August, to
facilitate fish migration,
holding and rearing; by mid-
September, temperatures should
not exceed 57 F to obtain
optimum egg survival.
Maintenance of DO and
temperature levels to protect
and restore the anadromous fishery in the South Umpqua would aid in
the abatement of biological nuisance problems.

3. Bacteria
Bacterial objectives for recreation and water supply use are
1,000 MPN and 5,000 MPN, respectively. Treatment, including disin-
fection, is required to reduce bacterial concentrations.
D. EVALUATION OF FLOW REGULATION REQUIREMENTS
Flow regulation for quality control is required in the South
Umpqua River to maintain the present and future use of the stream.
The maintenance and enhancement of the anadromous fishery is the
critical use requiring additional flow. Controlled storage re-
leases are needed to: (1) maintain dissolved oxygen concentrations
of at least 7 mg/1 during the months of July, August, September,
and October and (2) lower downstream water temperatures during the
same period.

DO-flow relationships
have been computed for the
South Umpqua for present
and projected loading condi-
tions. Two of these curves
are shown in FIGURE VIII -4.
Under present loading
conditions, the one-in-ten
drought flows of 80 cfs
in August and September
would result in average
DO levels of about 5 mg/1.
Under projected loading
conditions, the year 2000
with 85 percent treatment
is the most critical. With-
out flow regulation, DO con-
centrations during the crit-
ical period would drop below
_
3 mg/1. Diurnal fluctuations from these values would be about
1 mg/1. Under minimum recorded daily flows (36 cfs) near-septic
conditions would occur.
29
-------
Flow requirements, in combination with adequate treatment, and
storage requirements to meet deficiencies under one-in-ten drought
conditions are shown for the four critical months in TABLE VIII-5.
Reservoir releases are not needed during the rest of the year to
maintain over 7 mg/1 DO throughout the study period. However, it
should be noted that, if future development of the basin signifi-
cantly alters projected conditions, releases may be required during
winter months.

Based on this analysis, there is an immediate need for an
annual draft-on-storage— of 16,000 acre-feet and a maximum study
period need of 51,000 acre-feet.
2. Temperature
As shown in Chapter V, Section 4, present temperatures during
the summer months in the South Umpqua exceed those desirable for
the existing and potential fish production. Fishery agencies have
indicated that there would be considerable enhancement of anadromous
fish runs in the South Umpqua if temperatures could be lowered.
Although it is beyond the scope of this agency to recommend fishery
enhancement, the feasibility of meeting fishery objectives with
the Tiller project has been examined to assist fishery agencies.
Fishery enhancement criteria are temperatures of 57 F or
lower by mid-September and as low as possible during the summer.

I/ Annual draft-on-storage is the sum of incremental excesses of
needed releases over inflows during a climatic year (April to April),

Water Temperature Prediction and Control - Umpqua River Basin 1964
shows that the recommended temperatures could be maintained almost
to the mouth of the South Umpqua in all months except September
and October with releases from the Tiller project. Fall tempera-
tures could be met by allowing higher summer temperatures (up to
72°F) at the mouth and thereby conserving colder water for fall
release.
A schedule developed by the Corps of Engineers showing probable
releases from the Tiller Reservoir and the associated temperature
regimen for the South Umpqua is shown in TABLE VIII-6.

IX. BENEFITS
A. WATER SUPPLY - MUNICIPAL AND INDUSTRIAL
A future need for storage for municipal and industrial water
exists in the Umpqua Basin as described in Chapter VII. By the
year 2020, supplemental storage to yield 7.65 mgd or 2,350 acre-
feet will be needed. First need will begin at about the time of
assumed project completion (1975).
The value of this storage has been estimated by approximating
the single-purpose cost that would be required to develop the
needed supply in the absence of the Tiller and Galesville Projects.
The most likely alternative source available is on Jackson Creek
(Sec. 2, T30S, R1E). Based on this alternative, the annual value
of 2,350 acre-feet of storage in the project including operation
and maintenance is estimated to be $220,900, with a 50-year amor-
tization at an interest rate of 3.125 percent.
32
-------
B. WATER QUALITY CONTROL
the various uses requiring controlled water quality (fishlife,
recreation, and general aesthetics) were discussed in detail in
Chapter VIII, and it has been shown that the anadromous fishery
requirements are the most stringent. Other uses, however, will
benefit from the higher DO and reduced temperatures. Storage
releases from the Tiller and Galesville Projects are needed in
addition to adequate treatment to protect and maintain these uses.
Failure to provide flow regulation would allow further degradation
in the stream environment and cause further reduction of the South
Umpqua fish population.
Beneficiaries of flow regulation for water quality control
are widespread throughout the Umpqua Basin and the State of Oregon;
neither the polluters who contribute to the water quality degrada-
tion nor the users who benefit from the improved quality can be
specifically identified. The cost of water quality control in
these projects is, therefore, non-reimbursable.
The minimum value of storage for water quality control in the
South Umpqua is considered to be equal to the least-cost alter-
native in the absence of the Tiller Project. Waste disposal under-
ground, transmission of wastes downstream to the main stem Umpqua,
and waste lagooning are not feasible in the Umpqua Basin. The
least-cost alternative would be a single-purpose reservoir located
on Jackson Creek below the confluence of Luck Creek in Section 2,
T30S, RlE, which could provide the required flow regulation.
Based on this alternative, the minimum value assignable to an
annual draft-on-storage of 51,000 acre-feet, based on a 50-year
amortization at a rate of 3.125 percent, is estimated to be
$640,000.
The value of storage for fishery enhancement (temperature
control and flow stabilization) is assumed to be the value of the
enhanced fishery as determined by the fishery agencies concerned.
