IMPROVED AND ENLARGED WATER SUMY FOR THE CITY OF MEDFORD
A Report Made By F.
C. Dillard, Engineer,
and D. C. Henny,
Consulting Engineer.
To tlia Citizens of Medford:
Your Hoard of Water Commission
ers, after a most careful study und
survey of the water situation In Med
ford, covering a period of more than
three years, now helleves It to he
to the best interest of the city to do
the following things:
FIRST: llulld to the natural springs
on Big Butte Creek for your water
stipply. This Is the beBt supply of
water that it is possible for the city
to obtain.
SECOND: Build a steel pipe line
of treble the capacity of the present
line, with an estimated life of forty
years.
THIRD: Build a new cross-town
main to Improve general city service.
FOURTH: Bond the city for $975,
OliU.OO, serial bonds, all to he paid off
during the life time of the proposed
water system.
An ample Hiipply of mountain spring
water brought to Meiliord will be the
largest contributing factor in our fu
ture growth.
We submit the above recommenda
tions, based uiwn the advice of the
best engineers obtainable, together
with long and careful study on our
part.
You have the report of the engi
neers which we ask you to read care
fully that you may get the facts. The
matter is now in your hands for de-1
cision nt the coming election on Octo
ber Kill.
WATER COMMISSION,
CITY OF MEDFORD.
By II. L. Waltber, Chairman,
10. C. Caddis,
Olin Arnspiger,
A. L. Hill,
11. U. Lumsden.
September 1, 1925.
Board of Water Commissioners,
Medford, Oregon.
Gentlemen: The folowing is n re
port which you instructed us to make
ou an improved and enlarged wuter
supply lor the City of Medford.
BRIEF HISTORY,
1. The City of Medford was first
settled in 18S3 and was incorporated
by Act of the Legislative Assembly of
the State of Oregon, February 24. 18S5,
as the "Town of Medford," and rein
corporated February 7, 1905, as the
"City of Medford."
2. The population as given by the
U, S. Census was 907 In 1890, 1791
In 1900, 8840 in 1910, and 6760 in
1!)20. The population at the present
time Is estimated at 9000, The peak
of the Jackson ' -County "boom was
reached about 910 and the census
figure for that year must have In
cluded large numbers of floaters, la
borers and transients, ami undoubted
ly did not represent the true condi
tion. 3. The assessed valuation of the
City In 1900 was $1,048,959; In 191,
$4,033,185, and In 1924, $4,935,183. The
assessor advised that the valuation
for 1925 will be not less than $5,
329,000. 4. The first water Bystem was In
stalled In Medford in 1889. An open
ditch about three miles long was con
structed from Bear Creek, delivering
water to a well in the City, from which
it was pumped into two wooden tanks
having a capacity of 32,000 gallons
each. The tanks had an elevation of
about 77 feet above the center of the
business portion of west Medford. The
water was distributed- from the tanks
by gravity. In 1902 the ditch was
abandoned and a pumping plant In
stalled on the west bank of Bear
Creek. Steam power was first used
Jmt in 1904 a ten year contract was
entered into with the Condor Water
and Power Co. which supplied electric
power for pumping. The water was
obtained from a well on the banks of
Bear Creek and soon proved to he
unsuitable for domestic use. Accord
ingly steps were taken to secure a
pure gravity supply from some stream
or springs.
PRESENT SUPPLY.
6. Various sources were proposed
and Investigated. Utile Butte Creek
was finally selected as the source of
supply and on December 5, 1908, a
contract was entered into with the
Fish Iake Water Compnny whereby
the City agreed to pay the company
$254,100 for construction of a gravity
supply line and for perpetually sup
plying the City with 7V6 sec. ft. of
water. The amount Included in the
obove total for the purchase of the
7V4 sec. ft. or water was $15,000. The
work was completed and water served
from the new gravity line in 1910. The
lino has been in constant use since
that time.
6. Subsequently (he City purchased
348 acres of land (Stinger ranch)
above the pipe Intake with a water
right of 114 sec. ft.
7. Since the purchase of the 714
sec. rt. of water In 1908 and the build
ing Of the present pipe line, the Fish
loke Water Company was sold to the
Rogue River Valley Canal Company,
now Mt. Pitt Irrigation Company,
which constructed a storage dam at
Fish Lake. The lands In the reser
voir formed by the dam were left
uncleared of its timber and brush
growth, causing the water to have
a woody tnste and odor. In the fall
of the year when the lake .Is drained,
the water becomes discolored and "con
tains an algae growth which causes
a very pungent smell. The water at
this time Is very unpalatable and hard
ly suitable for domestic use. It has
been expected that by this time after
the lapse of- years the water would
be clear at nil times, but thrs has not
so far be'en the case, nor Is there any
assurance that It will ever be the cose.
8. Diamond Lake Is a mountain
lake very similar to Fish Lake. There
nre two seasons dtrlng the year when
the decaying vegetnble growth of this
lake lets loose and Is flushed out. The
algae here resemble those at Fish
Ijike. and make the water unfit for
domestic use or bathing. This Con,-,
illtion has existed at DiamonO Lake
for many years and as far as is known
dops not improve.

they would be very expensive to In-

10. On July 23rd. 1925, tempera-
lure tests were taken in the present
pipe line with the following results:
Distance
At Intake
At Pipe Lino Bridge
At Stand Pipe
At Mrs. McDonald's
At Tunnel
At James Owen's
At Well City Reservoir
In Reservoir No. 1
At House Faucet In West Medford
It Is not necessary to point nut
that the water Is too warm for drink
ing In the summer without being iced.
11. The present pipe line consists
of 21.9. miles of 10-in. machine banded
wood stave pipe. All pipe was dipped
but not creosoted under ressure.
Bunded collars were used. The maxi
mum head on the pipe is 375 feet.
The pipe is built wlih a fall of 4.333
feet per 1,000 feet, having a carrying
capacity of ti.1t. cu. ft. per sec.
12. During July or ui:a year, a care
ful examination was made of the phys
ical condition of the present gravity
pipe line. Mr. C. W. Davis, the City
Superintendent, had test holes dug
along the pipe line. The City em
ployees who regularly work on the
line were questioned and their Idea
is confirmed by a first hand exam
ination of the pipe Itself by Mr. F. C.
Dillard. The pipe was examined In
fifty places, selected at random, with
the following results:
Good .. 20
Fair 20
Poor 7
Very poor 3
By very poor, it is meant that a Btave
is decayed in some place und apt to
tail at any time, although the failure
would not he sufficient to put the line
out of use for any great length of
time. These particular sections of
pipe may last from one to three years
but the necessity of their early re
placement is certain. The portion of
t tie pipe under high head was usually
found in better condition than the
low head portion.
13. if the examination made can
be used as a criterion, then 3 50 of
the line is in very poor shape, or 1.3
mile. This is rather alarming. We
believe, even though the pipe line may
give service for the next three years
without many failures, before long,
however, the upkeep may be expected
to become very heuvy. The City in
the past eighteen months has expend
ed $38,798.51 in renewing collars,
about one-third having required re
newal. All the remaining collars will
need to he renewed within three years,
after which, as above stated, renewals
of the pipe itself wll continue to keep
the maintenance cost high.

our opinion that the number of com-

users Is probably above the average
in ttner cities, and the actual popula
tlon may therefore be close to 9000.
This number would give a maximum
dally per capita use of 430 gallons.
19. The portion of water consumed
in house use is not definitely known
as the city, except as to Industrial
consumption, Is unmetcred. It may,
however, be approximated by meas
urement ot the outflow from the septic
sewer tank which Rives some Indica
tion ot domestic and industrial con
sumption. The outflow during July
and August averaged about 1.6 sec. ft.
The industrial use as found by meters
was 0.50 Bee. ft. In June and 0.58
sec. ft. In July (nearly 10 of all
uses). This would leave about 1.03
sec. ft. for domestic consumption,
equivalent for a population of 9000 In

Rogue River Valley Is 0.6 A. F. per
acre per summer month. This would
make 102 A. F. for 270 A., an amount
equal to a steady flow of 2.7 S. F.
The very nature of City lawn and gar
den Irrigation makes water demands
high because of heavy evaporation.
Whether tills fact is sufficient to ex
plain the lnrge difference between the
figured supply of 4.4 Bee. ft. und the
ordinary agricultural requirements of
2.7 sec. ft. is uncertain. The lurge
figure undoubtedly contains some
waste and some slight loss through
main pipe leaks, which may he avoid
able by close Inspection or by meter
ing. 21. If the estimated domestic con
sumption og 1.03 sec. ft. should con
tain 20 waste and If Irlgatlon use
could he curtailed a like proportion
without detriment, then the summer
consumption by the present popula
tion of 9000 would drop from 6 to
4.9 sec. ft Such improvement could
probably not be secured without the
general Introduction of meters, but
would permit the Increase of Med
ford's population to 11,000 without the
necessity of Increasing the present
supply.
22. The present supply of G S. F.
during the summer equuls 430 gallons
per capita per day. A metered supply
of 4.9 S. F. would he equivalent to
352 gallons per- capita per day, all
on the basis of 9000 "population, in
earlier reports, such ns that of Eng.
W. ,1. Roberts of 1908, 160-or 100 gal
lons per capita per day was esti
mated as sufficient. The difference
in estimates is almost exclusively in
the Item allowed for irrigation as Is
evident from the following table:
Domestic use
Industrial use
Irrigation and waste

23. It wilt be seen that the present
Industrial and unmatured domestic
use muy aggregate 115 gallons per
capita per day and that the total re

Assuming that domestic use should
increase from 74 to 100 gallons and
that industrial and irrigation con
400 gallons per day. To this large
new Industries may make further ad
ditions. 26. Plans for the future should
take Into account probable growth of
population. The population grew from
6700 in 1920 to 9000 in 1925 or at an
average rate of 10 per year. The
number tit water taps Increased from
2159 In 1920 to 2500 In 1925, an in
crease of 3 per year. The reason here
for the difference In these percentages
Is probably the gradual occupation of
.vacant dwellings during the earlier
years followed by rapid resilience con
struction, the latter only affecting the
number of taps. (See in this connec
tion Fig. 2, plate 1.)
27. Med fori) is situated In the cen
ter of 35,000 acres of Irrigated land
for a large part of which Irrigation
works have been recently completed
and which is Just now beginning to he
cut Into small tracts. It Is entirely
reasonable to expert a great increase
In fruit and vegetable production dur
ing the next ten or fliteen years. This
will mean that canneries, creameries

etc.. will follow and facfltft where the
tat facilities Pan be obtained. Some
0f these Industries mav be heavy

1935 the City may contain over 15.000
people. After that the growth may
becomo somewhat slower, . but it is
easily possible that this number by
1946 may have reached 20.no.
30. Such population at the figured

of 400 gallons per capita would In
summer require 15 sec. ft. It seems

33. Filtration Is nn expensive pro

tion and is usually adopted only when
no pure supply is available within a
reasonable distance. In .Medford fil
tration would he excessively expen

now, it will require a filtration plant
which for every 74 gallons of domestic
consumption must necessarily filter in
addition almost five times this amount,

plied, a separatd costly pipe system

34. All this can be avoided If with

METERING OF SERVICES. 36. The
reduction of waste by metering mnkes
a strong appeal to every economist
- " --
would be possible.
30. Such conclusion Is not support
ed, however, by the rough estimates of
waste given In Section 21 and tending
to show that the saving to be effected
,1"' meters may not be greater than
J.0- It should be stated, however,
that in the absence of a thorough
waste survey, which has not yet been
made, this estimate had to be based
37- The possibility seemed attrac-
tivt nt nnatnnn np naur mn n ulna Una
tive of postponing new main pipe line
construction for a long time by the
introduction of meters. It now seems
probable that the time that new con
struction may thus he put off would
be only until the City population has
grown to 11,000 (see Section 21).
38. Postponement In main line con
struction in this manner would not
only Involve the expenditure of about
$50,000 for meters and the subsequent
cost of maintenance and meter read
ing, but would also require the main
tenance of the present wooden main
pipe line. This would necessitate an
annual expenditure of $26,000 for three
years for new collars and thereafter
the cost of gradual replacement of
pipe.
39. After all this Is done the City
would still be subject to the present
limitation of its water supply nnd to
Its unsatisfactory quality. It would
again soon be confronted with the
necessity of enlarging Its supply and
then, too, delay for. any considerable
time might render the City's present
good title to Big Butte Creek waters
questionable, due to not putting the
waters to benenclnl ubb.
AVAILABLE SOURCES OF 8UPPLY
COLD SPRINGS NEAR FISH LAKE.
40. ThlB spring Is located In Section
4. T. 37 8.. R. 4 E. of W. M.,-iust south
of the North Fork of Little Butte
Creek and about 33 miles from Med
ford. The source of the spring Is un
known, but It would appear that this
spring Is the outlet for the Big Llk
drainage area. No chemical analysis
is available. A bacteriological analy
sis was made and shows the water as
now flowing from the spring to be
of unquestioned purity. ' Its elevation
is 3100 feet above that of Medford and
ample fall Is therefore available for
carrying water to the City distribution
reservoir.
41. A record of the flow has been
kept by the It. 8. Geological Survey
for the years 1923 snd 1924. The cli
matic year of 1923-4 was the driest
since the weather bureau station was
established In Ashland In 1879. We
are told by old residents that the only
other year In their memory that ap
proached it was the winter of 1858-9,
nnd that It was no worse than the
past year of 1924.

BIG BUTTE SPRINC1S. 4(1. The
Big Butte Springs are located about
31 miles from Medford In Sections 20
and 21. T. 35 S.. H. 3 10. The water
Is of tile highest quality as is shown
ill the reiwrt of City Health Officer
Dr. E. B. Plckel. The temperature of
the water Is 43 degrees F. The ele
vation is 1300 feet above Medford and
therefore high enough for delivery
through a gravity line Into the Cl,ty
reservoirs.

OTHER SPRINGS ON BIG BllfTE
CREEK. 48. There nre other sprfligs
of apparently equal purity in the Big
Biftte Creek drainage area. However,
they are located farther away from
Medford than the Big Butte Springs
nnd are moreover witlely scattered and
expensive to collect. Their total flow
does not exceed that of Big Butte
Springs.
COMBINATION OF SOURCES. 49.
The flow ot Cold Springs may be
readily combined with that of Wassen
Creek thus making a totul of about
16 S. F. of pure spring water. It has
been argued that It can also he com
bined with additional water to be pur
chased from the Mt. Pitt irrigation
Company. Such purchase would seem
Inadvisable now or In the future be
cause the addition of water thus se
cured and Its merging with pure
spring water would leave the quality
nt the- mixture equally subject to ob
jection as is the present supply.
60, In any case acquisition is out
of the Question since the Mt. Pitt Irri
gation Co. has advised (lie Water Com
mission that "it does not care to fur
nish the City any additional wuter at
this time." The Board of Directors
of the Medford Irrigation District also
adviso "that they prefer to sell any
surplus water they may have to addi
tional acreage rather than disposing
of It for municipal supply." It Is cer
tain that the entire supply of both con
cerns will be Insufficient to Irrigate
the lands commanded by their ennuis,
from Rogue River. Both sources
would be under serious suspicion as to
purity and would Immediately or nt
an early date demand scientific filter

of the water collected at the present
city Intuke lower down on Little Butte
fCreek, the amount being 7V4 8. F.
plus 1 S, K. secured hy the purchase
of the Slinger ranch, making a totnl
of 9 8. F. Additional water would
have to be acquired by purchase.
52. The city has at present no ex
.press right to water from Mosquito
Creek, hut this right could probably
be obtained In view of the City's 'fil
ings on Big, Butte Creek and Big Butte
Springs.
63. The flow to Wassen Creek can
be claimed hy the City under Its gen
eral right to Little Butte Water limit
ed to 9 8. F. If the creek Is used In
conjunction with a greater use of Cold
Springs, the right of diversion would
have to bo purchased. If used In 'on
Junction with Mosquito Creek water
the present rights of the City to Little
Butte Creek. water would suffice.
64. As to the right of the City 10
use water from Big Butte Springs,
which Is a tributary of Jllg Butte
Creek. It may be stated lmit under

ESTIMATES OF COST
00. The only estimates of cost,
which it was deemed necessary to
make, refer to the cost of bringing In
a supply from Cold Spring in conjunc
tion with Wassen Creek, and a supply
from from Big Blltte Springs. The
flow from Mosquito Creek even if com
bined with that of Wassen Creek,
which could be picked up en route, is
clearly too small for consideration.
The supply from scatteretl springs
high, up on Big Butto Creek is not
superior to that ot Big Butte Springs
In quality or quantity and Is more
costly to deliver to Medford because
of groat length of collecting pipes and
longer main pipe line,
61. Detailed estimates show that
the tottii coBt of a 10.6 sec. ft. supply
delivered Into the city reservoirs from
either of the two sources mentioned
Is ns follows: '
Cold Spring and Wassen
Creek $877,000
Big Butte Springs 875.000
The estimates were based on Identical
character of construction, which will
he discussed later. The relation be
tween costs probably holds good for
somewhat smaller or lurger Bupply
mains.
COMPARISON OF 80URCES -02.
It Is now possible to Judge in
telllgeutly which or the available
sources Is most desirable. Mosquito
Creek and springs high up on Big
Butte Creek have been ruled out, the
rirst by too small quantity, tlle latter
by high relative cost.
63. On the point of purity, there
Is no definitely known dirrerenco be
tween the Cobl Sprlngs-Wassen Creek
and the lllg Butte Springs supply.
Both ure at present above suspicion,
snd can probably be maintained so.
There mnv lie relntlvelv mnm A rnln.
age area tributary to the rormer source
outside or the National Forest that
to the latter source, but In either case
ordinary precautions authorized by
law are likely to he effective'.
64. On the point of estimated cost
of main pipe linn, the two sources also
happen to be practically on a par. '
65. There Is, however, one out
standing feature operating greatly in
favor of the selection of lllg Blltte
Springs as un Immediate and perma
nent source of supply. If Big Butte
Springs be now selected and beneficial
use made of the water at an early
date, the City will thereby secure a
source of pure water supply which has
a .minimum flow of 45 sec. ft., with
an Immediate nnd definite right to 35
sec. ft. for average years and 25 sec.
ft. minimum. The rights to the full
45 second feet can nt any time In the
futifre be made good hy providing river

09. The conclusions.' drawn from the
Oeologlsts's report ure that the springs
nt'e as permanent as it is possible to
llnil springs, that tlie chances of con
tamination without protection ore ex
tremely small or . absent, that It Is
probably possible to collect all the
flow by a crosscut from tlie first grnun
of springs to the luat group, and that
It prohably would not be possible to
intercept the flow of the springs at a
higher elevation thereby making It
feasible to locate the main pipe line
through the Obencbaln pass.
70. The location of the main supply
pipe intake at the Springs will elimi
nate all chance of contamination such
as now exists to the present supply
between Fish Lake nnd the City In
take. Also the objection to frequent
muddy wuter In the house service pipe
will be removed.
SOURCE OF SPRINGS. 71. The
source of the water supply ot the
springs Is the precipitation on a largo
area to the east as far as the Cascade
divide. The constancy ot the supply
during summer Is unquestionably due
to tlie melting snow on Mt. Mclaugh
lin. The visible drainage area directly
tributary to the springs Is approxi
mately 10 square miles as shown on
the drainage map accompanying this
report. While we cannot be certain,
we are ot tho opinion that Mosquito
Creek contributes to the flow of the
springs. Geologist I. A. Williams Is
of the same opinion. Mosquito Creek
alone, however, Is not the sole source
of supply ns is shown by the ills-
cnarge measurements presented In
Section 37. On July 17, Mosquito
Creek was flowing 8 sec. ft. and the
combined flow of the springs was not
less than 54 sec. ft. To tlle northeast
of MtiBqultn Flat, well up the slopes
of Mt. McLouglillh, and outside the
Mosquito Creek drainage area, run
ning wuter can be heard below the
surface of tho lava rocks. No water
Is visible and farther down the slopo
it cannot he heard at all, nor Is there
nnv evidence of a stream bed.
72. Soma time In the past there
may have existed a drainage svstm
for the northwest portion of Mt. Mc
Laughlin which has later been filled
with a- flow or successive flows ot
lava. This lava Is more or less ixirous
nnd provides a valuable storage basin
for the runoff of the northwest portion
of the mountain. The water slowly
finds Its way down the old channels to
the point where It breaks out as
springs.
73. The opinion has been advanced
by some that the source of the springs
Is the Four Bit Creek and Rancherln
Creek mnrsh. Elevations taken with
un aneroid barometer show that the
upper end of this mnrsh Is a little
lower than the Big Butte Creek
Springs antl that the real marshv por
tion Is between 20 and 40 feet lowor.
The mnrsh Is prohably nothing more
than beaver dam land with submerged
springs. Springs can be seen cropping
out all along the east side of the
marsh. It Is certain that none of the
wnter passing through this marsh evor
reaches the springs. t Even If tho
marsh were at a higher elevation than
the springs It Is not probable that
any of the water of the marsh would
ever rind Its way to the springs for
the reason that the well defined drain
ago channel of Four Bit Creek lies
between the marsh nnd the springs.
