Mr. Felix L. Sparks, Director
Colorado Water Conservation Board
Columbine Building
1845 Sherman Street
Denver, Colorado
Dear Mr. Sparks:
We urge that the Colorado Water Conservation Board request the
Bureau of Reclamation to reactivate a study for transmountain
diversion of water from the headwaters of the Colorado River to
the South Platte Valley substantially along the lines of the Blue
River South Platte Project previously submitted to this Board in
1940 and again in 1948. These reports were neither approved nor
rejected. We also ask that this Board integrate and coordinate
all flood control projects, existing, authorized and planned into
a multipurpose water, power, flood control and recreation project.
Central seeks the cooperation of the Water Board of the City and
County of Denver, the Lower South Platte Water Conservancy District,
the Northern Colorado Water Conservancy District and all cities
and irrigation organizations in the South Platte Valley toward
the development of a coordinated water and integrated water and
land resource plan for the entire South Platte Basin. The entire
South Platte Basin including the City of Denver and the Denver
Metropolitan area can best be served by a coordinated multipurpose
water resource development program.
We suggest that the projects already constructed by the City
and County of Denver and the United States Corps of Engineers, as
well as those planned,be coordinated.
Long range water plans for the cities tor municipal and industrial
use are made immediately feasible by including recreation, irrigation and power uses. Without immediate recreation, power, and
agricultural use, construction of multimillion dollar projects for
municipal and industrial use in the distant future makes the present
debt service charge an inordinate burden on the city.
Page 2
Mr. Felix L. Sparks
March 25, 1968
Attached is a description of the proposed Central-South Platte.
Central's project is based upon the former studies.
The new study should recognize the construction of Cherry Creek
Reservoir, Dillon Reservoir and Roberts Tunnel, all completed
essentially as planned by the Bureau. The Denver Water Board
should be compensated for the use of its facilities. The study
should protect, conserve, improve and coordinate works already
constructed, now in the process of construction and in final
planning.
The Central-South Platte study should provide for adequate replacement storage to the western slope. Such replacement storage should
require western slope beneficiaries to assume that part of the
financial burden within their ability to repay upon growth of the
municipalities and the anticipated industrial areas incident to
western slope resource development.
CHATFIELD RESERVOIR
Chatfield Reservoir was a part of the Blue River South Platte
proposal of the Bureau of Reclamation and the Corps of Engineers.
Chatfield was originally authorized without conservation storage.
It should be a multi-purpose reservoir. It can and should be
built to fit into the proposed Central-South Platte Plan, the
filings of Central and the coordination with Narrows. Chatfield
can and should provide for storage of the unappropriated waters
of the South Platte River estimated to be between 12,000 and 15,000
acre feet per year. Principles of operation for Chatfield should
provide terminal storage for water which can be brought through
the Roberts Tunnel under the present condition of the North Fork
for use by the City of Denver or by the irrigation interests.
Joint use storage should be included in Chatfield Reservoir in
accordance with established principles of multi-purpose construction of the Corps of Engineers and the Bureau of Reclamation.
Central hopes that holdover storage can be provided in Chatfield
Reservoir by invasion of the capacity reserved for silt until
such time as Two Forks Reservoir on the Platte is constructed.
Chatfield could accumulate a portion of a water supply for the
succeeding irrigation season. Chatfield should supplement existing
reservoirs owned by companies within the boundaries of the district,
Barr Lake, Horsecreek, Prospect, Bootleg and Milton, and supply
direct irrigation to lands within the district.

CHERRY CREEK RESERVOIR
The plans for Cherry Creek Reservoir provided for conservation
storage of 85,000 acre feet as part of the overall Blue River
South Platte. Cherry Creek Reservoir is now being used for
recreation. Central seeks space for conservation or joint use
storage in Cherry Creek. Soree additional work will be required.
USE OF DENVER'S FACILITIES
Central proposes immediate use of Denver's facilities, the
Roberts Tunnel and Dillon Reservoir, subject to Denver's rights,
for immediate transmountain diversion. Years ago there was a
great deal of discussion to whether Denver should build the high
or low dam at Dillon. Water investigations then indicated that
the maximum Denver could expect from the Dillon Reservoir without
additions to its collection system on the East Gore Canal and
other areas would be 125,000 acre feet a year. After canvassing
the irrigation interests in Northeastern Colorado and after
receiving declarations of intent fro~ irrigation interests to
either purchase water from the City of Denver or to use the City of
Denver's facilities for bringing water from the Western to the
Eastern Slope under their own filings, the Denver Water Board
constructed Dillon Reservoir to its capacity of 252,000 acre feet.
Dillon actually filled
drawal of water Dillon
the coming of the high
will then be available
in two years. Except for recent withwould now be full or nearly so. With
runoff period Dillon will refill. Water
for call by Central under its filings.
Outright purchase of water for irrigation by Central from Denver
out of the Dillon-Roberts system is prohibited by the Blue River
decree of the United States District Court for the District of
Colorado. In Central's view the prohibitions are uneconomic,
contrary to the Constitution of Colorado and unenforceable.
Beneficial use, not prohibition of use is the fundamental theory
of Colorado's doctrine of prior appropriation. This natter should
be resolved amicably between the Western Slope, the Denver Water
Board and Central to their mutual benefit and that of the State.
Compensation to the Bureau of Reclamation for power loss can be
made. All should recognize the preference of domestic and agricultural use over power production under the Colorado Constitution,
the Upper Colorado River Compact, the Colorado River Compact and
Senate Document No. 80.
Page 4
Mr. Felix L. Sparks
March 25, 1968
Central, by use of Denver's facilities and upon p1yment of fair
compensation to Denver could deliver some 125,000 acre feet of
water to farmers within its boundaries in 1968. The rate of
compensation to Denver, must recognize loss in transit, seepage
and evaporation, existing river conditions and the ability of the
farmers to pay. This procedure was suggested by representatives
of the Denver Water Board.
If an agreement between Denver, the Western Slope and Central
cannot be negotiated, Central contends it can call for diversion
of water under its filings thr.ough the Dillon-Roberts System
of the Denver Water Board upon payment of reasonable co~pensation
to it. It is a recognized principle of Colorado water law, that
one water claimant may use the unused capacity of anothers works
to transport his water.
The soundest approach to the water problems of the entire l!etropoli tan Denver area is to combine municipal, industrial, irrigation
and recreational use with power production. Cooperation of Denve~,
the Metropolitan area outside of Denver, the irrigation interests
with the help of power production can provide water, recreaticn
and power at a cost far less than can be done in any other way.
When the cities of Greeley, Fort Collins, Longmont and
Loveland teamed up with the irrigation interests in the 1930's
to plan the Colorado Big Tho~pson transnountain diversion project,
Denver and its metropolitan areas requested the Eureau of R9clnmation to plan a trans~ountain diversion project for the~.
Denver, AdQms, Arapahoe, Boulder, Douglas, El Paso, Jefferson
and Weld Counties combined, sought and supported the Blue River
Eagle transr.iountain diversion.
Denver has incurred such a tremendous investment on water for wh~ch
it has no present neeci within its present service area, and which
it is unable to sell at the price it asks. De~ver needG the
metropolitan area outside the city acd the irrigation interests
in order to put together a project which will reduce the cost to
the entire area by means of i~mediate income from irri~ation,
power and recreation interests. Immediate transmountain diversion
of all water which could be carried throvgh the Roberts Tunnel
and through the North Fork of the South Platte in its present
condition would bring im~ediate income from the irrigation
interests, cities, tovmsJ and ind.'..lstri2.l areas and r::.ake possible
generation of power.
We suggest the advis~bility of negotiations between Denver, the
Metropolitan area cities and Central, ns well as the State and
Page 5
Mr. Felix L. Sparks
March 25, 1968
Federal recreation interests, so that a united front could be
presented in order to obtain a Bureau of Reclamation Project.
Without the expenditure of any sizable funds and by cooperation
between the Denver Water Board, the Western Slope interests,
Central, the State Engineer and State and Federal authorities,
up to 200,000 acre feet of water can be made immediately available to the South Platte Basin without any injury or detriment
to Western Slope interests. Such transmountain diversion would
add as much water to the South Platte Basin as is delivered by
the Colorado Big Thompson Project under its average delivery.
At todays agricultural prices, this water applied as a supplemental water supply to presently irrigated land will add an estimated $150.00 for each acre foot of water or a total addition
to the economy of Colorado of a possible $30,000,000 annually.
Central could afford to pay Denver a rental of $2.00 per acre foot.
This could mean immediate cash return to the Denver Water Board
an estimated $400,000 annually for rental of its facilities
which it could not otherwise get.
Everyone, laymen, engineers, and lawyers alike agree that the
best protection of the water to which Colorado is entitled is
to put it to immediate use. We of Central cannot see any
disadvantage to any person whatsoever in putting to immediate
use water to which the Denver Water Board has the established
right. There are other possible differences between the
Western Slope interests and Central, but on this single point
there can be no reasonable disagreement with the statement
that putting to immediate use the entire amount of water which
Denver will ultimately need in accordance under its final and
conditional decrees cannot in any way damage the Western Slope.
Use by Central of water under its filings would be subject to
Denver's priorities. As Denver's need increased, Central's
diversion through Robert's Tunnel would decrease. The return
flow would still be available to the irrigators.
We urge the immediate cooperation of Denver, the Western Slope
interests and Central to divert the maximum amount of water
through Roberts Tunnel in 1968. We urge the support of this
board in activating a study of the Central-Sputh Platte plan
as a Bureau of Reclamation Project. Finally, we urge a long
range study of the integration of the South Platte Valley water
resources including surface,transmountain and ground water supply
for basinwide management.

The collection system fro'in the Eagle River will start at Cross
Creek on the West and pick up the tributaries--Homestake Creek, Turkey
Creek, Game Creek, Mill Creek, Gore Creek, Black Gore and the outlet from
Piney with a total capacity of 1,200 cubic feet per second through Vail
Pass Tunnel. Water from this area will be regulated in Pando Reservoir
on the Eagle and Piney Reservoir on the Piney.
Water from the Vail Pass Tunnel, capacity 1,200 c.f.s., plus the
water developed on the Blue River will be regulated and stored in Ten
Mile Reservoir and Frisco Reservoir, both on Ten Mile Creek, in the
Blue Reservoir on Blue River, and in the Snake Reservoir on the Snake
River.
A power plant will be located below the Ten Mile Dam to produce
peakirlg power by dumping into Frisco Reservoir.
-1-
The Collection System on the Blue River ~ill start at Sheephorn Creek
and extend southerly along the east side of the Gore Range picking up
tributaries of the Blue River. The system will connect with outlets of the
reservoirs on the Blue River, thence north along the east side of the Blue
River, picking up water from its tributaries, then crossing over to the
Williams and Fraser Rivers to pick up water from those two streams and
the ir tributaries. The canal system will lead into a tunnel located just
south of the Moffat Railroad Tunnel, with a capacity of 1,500 c.f.s.:
Water from the Williams River will be regulated and stored in Leal
Reservoir located on the Williams River.
Waters from the Fraser will be stored and regulated in St. Louis
Creek Reservoir on St. Louis Creek, Vasques Reservoir on Vasques Creek and
Fraser Reservoir on the Fraser River. All the water collected from the
Eagle, Piney, Blue and Sheephorn drainage areas will then pass under the
Continental Divide in the Moffat Tunnel, a gravity tunnel paralleling the
Moffat Railroad Tunnel. Moffat Tunnel has a capacity of 1,500 c.f.s. and
length of 6.4 miles.
A portion of the water can be diverted under the Continental Divide
in the Roberts Tunnel of the Board of Water Commissioners City and County
of Denver if arrangements can be made with Denver. Any water brought
through Roberts Tunnel would be carried to Clear Creek and produce power at
a plant located just below Forks Reservoir on Clear Creek.

and then to a power plant below Forks Reservoir Dam on Clear Creek.
All the water collected from the Western Slope and delivered into
Clear Creek will be carried to a power plant at the upper end of Van Bibber
Reservoir north of Golden. The water will be regulated and stored in Van
Bibber Reservoir. The portion of the water for domestic use will pass
through a master filter plant and be distributed to all domestic users from
Van Bibber. Water for irrigation will pass into Clear Creek and be used as
needed. Empire and Forks Reservoirs will regulate Clear Creek waters by
delivery to ditches on Clear Creek and the South Platte River to ditches
serving the present area within Central Colorado Water Conservancy District.
Annexation to Central will be required of all water users.
Water entering the South Platte will be a supplemental supply for
existing ditches, ground water recharge, exchange, and for new lands as
the supply warrants.
Boxelder, Hudson, Muddy and Narrows Reservoirs will serve as regulation
and storage facilities for western slope, as well as eastern slope waters.
Waters of the South Platte and the western slope will be regulated
and stored in Two Forks, Waterton and Chatfield Reservoirs. Between Two
Forks and Waterton and between Waterton and Chatfield Reservoirs peaking
power will be produced.
The total runoff above the western slope collection system is over
900,000 acre feet annually. Storage on the western slope is 2,121,352 acre
feet. Storage on the eastern slope is 3,272,214 acre feet.
The estimated average annual diversion from the western to the eastern
slope is 750,000 acre feet, all of which would be available for power production. 570,000 acre feet will be available for use within Central Colorado
Water Conservancy District and its extensions, exclusive of water delivered
to the City of Denver.

Statements of claim made by Central Colorado Water Users Association
were accepted for filing with the State Engineer on August 2, 1957 for
Pando, Piney, Ten Mile, Blue, Leal, Empire, Van Bibber, Waterton, Cherry
Creek and Narrows Reservoirs, and collection systems. These claims are
now owned by Central. Central has filed on Chatfield Reservoir, and will
file final claims on all other parts of the Central South Platte proje~t,
including those on which preliminary statements have been made. Central
has also filed on Roberts Tunnel.
Central recognizes joint use with federal and state agencies, and with
other Colorado Municipalities in Forks, Two Forks, Waterton, Chatfield,
Cherry Creek, Mt. Carbon, and Narrows Reservoirs, to achieve basin wide
water management on the South Platte River.
III
SOUTH PLATTE GROUND WATER ACQUIFERS
Central has filed its statement of claim on all unappropriated water
in the aquifers along the South Platte River and its tributaries in the
office of the Colorado State Engineer. Central proposes a ground water
management program to make optimum use of ground water along the lower
reaches of the South Platte River. Such use and exchanges upstream could
help satisfy all present surface and ground water uses upstream. Optimum
ground water use, properly managed, should reduce calls up the river and
keep present irrigation wells in operation. Optimum use should be made of
the ground water aquifers in coordination with surface water diversions.
Presently operating irrigation wells along the South Platte and its tributaries can be kept in operation without injury to surface appropriations
provided optimum use is made of the ground water.
Flood waters impounded in Cherry Creek Reservoir, Chatfield Reservoir
and other proposed reservoirs should be released for ground water storage
and recharge when not needed to satisfy surface ·/decrees. Ground water
aquifers in the South Platte Basin should be used for cyclical storage to
supply present ground water uses and to supplement surface flow in dry
years.

AVATI,A,BLE WA'IER SUPPLY
FROM
THE COLORADO RIVER
FOR
THE CENTRAL COLORADO WATER CONSERVANCY'S BLUE RIVER-SOUTH PLAT'IE PROJECT
Using Secretary Udall's February 1, 1968 average virgin .flow of the. Colorado River<
at Lee Ferry for the period :1.906-1967 inclusive, at 1.4,963,000 acre feet and deducting
7,500,000 for the Lower Basin and .50,000 acre feet for Upper Arizona,••••••••
there is left for Colorado 3,836,277 acre feet.
.1
Deducting Udall's, or rather Bureau of Reclamation's estimate of unaccounted for
water or 2,25:1.,000 acre feet, due to Colorado's use
(by the
year 20307), there is left 1.,585,227 acre feet of Colorado water unused. Deducting the
570,000 acre feet average available, above the collection system and avail.able for the
Conservancy District's use, there is still left an excess of 1,015,227 acre feet.
Reference is made to the table, entitled, "Comparison o.t •••• • etc. 0 , attached hereto
which was based on a :1.900 to 1965 Study which shows an excess of 1, 180, 500 acre feet with
an estimate of 246,000 acres of new lands irrigated on the West Slope.
Ford, Bacon and Davis, one of the most respected Engineering Firms in New York City,
had occasion several years ago to study the run-off of the Colorado River with respect to
what was available for use in Colorado.
They got the U.
D. C. to collaberate with them in this study.
s.
Weather Bureau in Washington,
After making this study, which was very thorough, they could not justify the water
consumptive use figures gotten out by the Engineering Advisory Committee for the Upper
Basin, in fact, they proved by wind movements,topography and climate in general that the
Colorado River was in a very nearly closed basin and that the prevailing winds from the
Southwest to the Northeast carried not only moisture from the ocean and Gulf of Celi.tornia,
but picked up moisture from lakes, streams and irrigated areas within the basin and precipitated it when cooler air was encountered as over mountain ranges within the basin and
the mountains surrounding the basin.
They found that for the winds, blowing over the lakes, like Glen Canyon, in order to
carry the evaporation from that lake entirely out of the Ba.sin, as some contend, its normal direction would have to shift 90° in direction and that by some freak of nature, it
would not precipitate this water when cooler air was encountered as was customary with all
other water, but would hold it until it was out of the basin.
A study of the South Platte River shows by actual measurements of the surface infl.ow
and the outnow with no consideration given to the water that gets .into the 2.5,000,000
acre feet underground aquifer that the unaccounted water amounts to only 0.8 of an acre
foot for each acre irrigated.
The Bureau of Reclamation figures for West Slope water uses that a.re unaccounted for,
amounts to 1.11. acre feet per acre irrigated.
The Advisory Committee's estimate of 2.33 is 2.:1. times that used by the Bureau of
Reclamation and 2.9 times that on the South Platte from actual stream flow records covering many years.
Why anyone interested in Water Conservation in Colorado, the state which fumishes
7:1.~ of the entire fiow of the Colorado River at Lee Ferry and which by Compact is en-
titled to only 51.75i of one half of the total would further reduce Colorado's share
by at least 2.9 times the aetual amount is impossible to answer.
