2. GUEST: DANIEL OWNERS -1211 E. BATES PKWY. -SEWER LINE
VARIANCE TO BUILD A GARAGE.
Mr. Daniel Owens of 1211 E. Bates Parkway appeared to request the Board grant an
exception to the Municipal Code 12-3-K which requires him to replace the existing sewer
service line under his new proposed garage. Mr. Owens noted that he picked up the
information and requirements for building a new garage in December 2001. The
ordinance requiring him to replace his line was passed in January 2002 and he was
unaware of the new ordinance until his contractor told him of the additional expense. He
explained the hardship that would be created by having to replace the sewer service line.
Mr. Fonda reviewed the original reasons for passing the ordinance. The only section of
line that would have to be replaced would be the section going under the garage.
The Board recommended allowing an exception and with instructions to the City
Attorney to draft an agreement that would be recorded against Mr. Owen's property
stating that an exception was granted and the sewer line under the garage does not meet
code.
Mr. Kasson moved;
Mr. Otis seconded:

the Community Development Department.
3. CITY DITCH AUGMENTATION PLAN.
The Board received a copy of the Application for Approval of Plan for Augmentation for
the City Ditch that has been filed in District Court by David Hill, Englewood's Water
Attorney.
4. FLUSHERJV ACUUM TRUCK.
The Utilities Department staff has requested a combination flushing/vacuum truck that
will allow the crew to remove blockages at the first point of contact rather than having to .
flush the debris to the nearest trunk line. The proposed truck will allow removal of the
blocking solids at the point of the problem instead of progressing through the entire
system to the treatment plant. The cost is expected to be approximately $200,000. The
board is being asked to recommend the purchase to Council before final bids are received
due to the hazardous nature of the existing flusher truck.
Mr. Habenicht moved;
Mr. Cassidy seconded:
Ayes:

5. WATER TASTE & ODOR CONCERNS.
The Board received a memo dated May 1, 2002 from Stu Fonda to Englewood City
Council regarding recent taste and odors in Englewood's drinking water. Due to current
drought conditions there are little or no flows being released from Chatfield Reservoir.
The slow flow rate, combined with the sunlight and nutrients present, are causing algal
blooms in the river. Algae produces oils which can pass through the treatment plant
process. These oils, even in low quantities, produce objectionable taste and odors.
In an effort to improve the taste of the water, the Allen Filter Plant will be increasing
diversions down the City Ditch and introducing powdered-activated carbon. The Utilities
Department will be considering whether long-term powdered activated carbon facilities
should be added to the treatment process.
6. HOLIDAY PARADE.
The Board received a memo from Council member Olga Wolosyn regarding the 2003
Englewood Holiday Parade . Various boards and commissions are being encouraged to
sponsor a float, volunteer to work the parade or apply to serve on the parade committee.
7. RATE INCREASES .
Stu notified the Board that water and sewer rate increases are being discussed. The Bi-
City Supervisory Committee is reviewing pending regulations that will be affecting future
rates. Rate increases will be discussed at future Council study sessions and a joint
meeting with the Littleton City Council.
8. CENTENNIAL AGREEMENT.
Negotiations are nearing completion for the Centennial water agreement and should be
ready for Water Board review by early fall. Stu noted that voluntary watering restrictions
are now in place.
The meeting adjourned at 5:55 p.m.
The next Water and Sewer Board meeting will be Tuesday, June 11, 2002 in the
Community Development Conference Room.

My of'i ce has been asked by Mr. Bill Miller of 2319 West Harvard Ave ., Englewood , Colorado 80110 , and
others , to inquire into what appears to be a considerable gnat problem in the area between Federal Boulevard
and Santa Fe Drive in the commercial and residential areas near the Platte River and the Excel power plant
in Englewood , Colorado .
After inspecting the area , and after talking to residents and bus iness owners in the area , it appears that there
has been a considerable increase in recent years of the number of gnats in the area causing residents and
business owners to consistently suffer from gnat bites . Some have even gone to their physicians to receive
special mediation to combat the discomfort and effects of the bites. It appears to me that the increase in the
number of gnats is a result of numerous areas of standing water from streams which eventually flow into the
South Platte River. Having seen the gnats myself, and after talk ing to some of the people in the area , the
situation appears to be a public nuisance.
It is my understanding that the State Health Department and City of Englewood have investi gated this matter
at the request of Mr. Miller , but have decided to not to do anything . I would appreciate it if you could write to
me and let me know what investigation was done and whether a state or private entomologist was consulted
to investigate the cause of the gnat problem , whether the number of gnats in the area is typical, and if not
typical , what could be done to reduce wha! :nar.y bel ieve is a public health !hreat.
Your consideration and attention is appreciated and I look forward to hearing from you in the not too distant
future .

RE: Mr. Bill Miller, 2319 W Harvard Ave , Gnat problem
I met with Mr. Miller on Thursday , April l 81h to investigate his complaint of raw
sewerage being discharged into West Harvard Gulch and the resulting insect infestation
in his neighborhood. M r. Miller contends that the insects are adversely affecting his
quality of life and that the source of these insects is West Harvard Gulch.
Together, we toured West Harvard Gulch from the S. Platte River to Federal Boulevard.
We were unable to locate any signs of raw sewerage being discharged into the gulch but
did observe several areas of slow moving stagnant water due to the low flow in the gulch .
The slow moving water is excellent breeding grounds for insects. These areas both
upstream and downstream of Mr. Miller 's property are in unimproved sections of the
gulch located in the City of Denver. The City of Denver has plans for a bike trail along
this section of the gulch but these improvements include only minimal channel
improvements. In the City of Englewood , West Harvard Gulch runs through the
Northwest Greenbelt where the gulch has been improved with a lined low flow channel.
Finally, I spoke with Mr. Jody Erwin of Tri-County Health and Mr. Dale Condra of State
Health Department. Both have investigated Mr. Miller's claim. They found no evidence
of raw sewerage being discharged and the insects to be a nuisance species , not a public
health threat. Therefore they took no action .
At this time, I recommend that Mr. Miller either spray his property or purchase an
electric insect sapper.

DRAFT
HOTEL SEWER TAP AGREEMENT
THIS AGREEMENT, is made the __ day of , 2002, between the
CITY OF ENGLEWOOD whose address is 1000 Englewood Parkway, Englewood, Colorado
80110, (hereinafter City); and the DEN MAR LLC an Indiana Limited Liability Company,
whose address is 1000 E. 80th Place, Suite 600N, Merrillville, IN 46410, (hereinafter Den
Mar).
WHEREAS, Den Mar requested a reduction in sewer tap fees because they believe their
Hotel's water usage is l ess per unit than a single-family equivalent. The subject Hotel is
located 10325 Park Meadows Drive, Littleton, Colorado, also known as Parkridge Marrida
WHEREAS , the standard tap fee is based on a normal flow of two hundred (200) gallons
per day and Den Mar estimates that their per unit flow is no more than one hundred (100)
gallons per day.
NOW THEREFORE the Parties agree as follows:
1. The City will sell 278 sewer taps for its Hotel units at one half the standard sewer
charge , based on their estimate of no more than 100 gallons per day per occupied unit
real flow . This is a minimum charge and in no event will the base tap fee be less than
one-half (1/2) the standard sewer charge.
2. The initial tap payment to the City by Den Mar will be $194,600, for Englewood tap
fees ; $12.50 for the permit, and a Big Dry Creek Interceptor Basin Charge of
$13 ,900 .00 , for a total of $208 ,512.50 .
3. Den Mar will issue an irrevocable, stand-by letter of credit in the amount of
$208 ,500 .00 , which will be used for any additional tap fees. This letter of credit will
be held by the City for tap fees as required pursuant to this Agreement.
4. The City will monitor winter (November 1 through April 30), bi-monthly water usage
at the Hotel during a five (5) year period . During that time, Den Mar will monitor
water consumption on a daily basis. Den Mar will furnish the City with a report on
daily water consumption and the number of rooms occupied on the corresponding days.
They will submit the report to the City on a monthly basis.
5. If at any time during the five (5) year period, the daily, per unit consumption goes over
one-hundred (100) gallons per day, Den Mar will pay the additional tap fee owed. If
the fee is not paid within sixty (60) days, the City will make periodic draws on Den
Mar letter of credit to pay to the City additional sewer tap fees based on the amount of
flow in excess of one hundred (100) gallons per day as billed by the City of Englewood.
If Den Mar's daily, per unit usage is less than one hundred (100) gallons per day, the
City will not owe Den Mar any refund.
6. Additional sewer tap fees will be computed on the basis of two hundred (2 00) gallons
per day being equal to a tap fee of $1,500.00. As an example , if the usage goes over
one hundred (100) gallons per day by five (5) gallons per day , then five (5) gallons per
day is two and one-half percent (2 112%) of the two hundred (200) gallons per day, two
and one-half percent (2 112%) ofone thousand five hundred dollars ($1,5 00) is thirty-
seven dollars and fifty cents ($37.50) times one hundred and sixty-one (161) hotel
units is six thousand thirty-seven dollars and fifty cents ($6,037.50) in additional
sewer tap fees. The higher amount, in this example the 105 gallons per day per unit,
will become the new base line for tap fees. Once the baseline reaches 200 gallons per
day, per residential unit, the maximum tap fee will be owed. In no event shall the
total tap fees exceed one maximum tap fee per unit.
7. However, should additional units be added to the project at any time , the tap fees
shall be increased by the number of additional units. If the units are added after the
five (5) year period described in paragraph 5 above , or after a final base line for tap
fees has been reached, the tap fees for the new units will be the same as the final tap
fees for the original units.
8 . Any accidental discharge of metered water of an unusual and non-recurring nature
where the City is notified within 24 hours of discharge and Den Mar provides
documentation of t he nature and extent of the discharge may be excluded from the
calculation of the tap fees. The filling of a swimming pool will not be considered an
accidental discharge under this paragraph.
9. At the end of five (5) years or on the date on which Den Mar has paid the additional
sewer tap fees associated with an increase in the baseline for tap fees to 200 gallons
per day per unit, whichever event shall occur first, the letter of credit may be
withdrawn and the City will no longer monitor water usage except for normal, annual
sewer billing purposes.
10 . Any. additional tap fees paid pursuant to this agreement are tap fees only and shall
not be considered sewer treatment char ges. Any money owed the City under this
Agreement is a fee for the sewer tap.
11. The City and/or its auditor maintains the right to enter the property to examine the
water use records , the hotel occupancy records and to check water meter readings.
12. Den Mar gives the City the right to disconnect the hotel for nonpayment of any tap fees
or sewer treatment fees due the City.
13. This Agreement shall not be assigned by any party without the prior written consent
of the other and this agreement shall be binding on any successors or assignees.
14. Den Mar confirms it has 278 units in this Hotel and agrees that it shall not add
additional hotel units to the City of Englewood's sewer system without written
approval of the City.

15. Any notice required or permitted by this Agreement shall be in writing, and shall be
deemed to have been sufficiently given for all purposes if sent by certified mail or
registered mail, postage and fees prepaid, addressed to the party to w horn such notice
is to be given at the address set forth below, or at such other address as has been

Dear Mr. Fonda:
Arr.
In response to your request, I have prepared the following work scope that outlines the process THK
will follow to establish the current and anticipated value of the seven to ten-acre proposed Transit
Station/Village property and adjoining nine acres of parking, which is part of the City of
Englewood's holdings in the Highlands Ranch Business Park. Specifically, the site is located at the
southwest corner of C-470 and Lucent Boulevard. We understand that this preliminary value
estimate will be used to formulate a strategy for negotiating a lease of the property to the RTD. In
order to formulate this value estimate, THK will prepare a current and anticipated value for the site.
Current Value
Regarding the current value of the property, THK will research recent land sales and land leases in
the Highlands Ranch Business Park vicinity. This data will include:
•
•
•
•
•
•
•
Size and location
Sale or lease terms
Zoning
Terms
Grantor and grantee (lessor/lessee)
Availability of utilities
Other important parcel characteristics
Using this data. THK will estimate the current value of the subject property.
Value as a Transit Station
Knowing that the parcel will be used for a transit station/village, THK will also research the sale or
lease of property for other transit stations/villages in the metro area. For these properties, we will
obtain the same information as described above. A review of this data will allow us to determine if
the use of the property as a light rail transit station/village is in-line with a more traditional land use.

Future Value
Recognizing that the local economy is somewhat depressed, THK will estimate what the land values/
lease are likely to be in two to three years when the economy is expected to be fully recovered.
Fee and Timing
THK professional fee for this assignment would be $5,450 plus direct expenses for mileage and
report reproduction. We can complete this assignment by the June 17, 2002 deadline.
If you have any questions or require any additional information, please do not hesitate to contact us.

Subject: Water Supply Outlook for Englewood
I. 2002 Water Supply Outlook for En~lewoo<i
A. Introduction
Englewood owns several very senior water rights which divert from the
South Platte River at Union A venue. While these water rights provide the
City with an ample supply of water, in dry years, such as the summer of
2002 appears to be , the low streamflow in the river, to~ether with the
demands for water from other senior riihts, may result in the City's senior
river ri&hts not being able to provide the City with all of the water needed.
In order to answer the question of whether the City's senior river rights will
be able to supp ly the C1tis needs · during the year 2002, the followini
analysis was performed.
B. Analysis
1. River Streamflows
Historical river streamflows for the year 1954 were taken to represent
streamflows of the year 2002. The year 1954 is generally regarded as
the driest year with the lowest streamflows of record for the South
Platte River . Whether strcamfl.ows in the year 2002 will actually fall
as low as those historically recorded in the year 1954 is anyone's
&uess, but the 1954 streamtlows were used to test the ability of
Englewood 's senior river rights to satisfy the City's year 2002 water
requirements .

2002 05/06 KON 15:44 FAI 3035262624 MARTIN AND WOOD WATER 444 Englewood Utilities Ill 003 /010
2. Englewood Wat.er Requirements
En~lewood's daily water requirements for the year 2002 were taken to
be the daily water requirements historically observed for the year
2001, but with the City's year 2001 daily irrigation water requirement
increased by 15 % to represent the hot and dry conditions which may
oceur in 2002. For reference, the City's total raw water requirement
in 2001 was 9,600 acre-feet, with a maximum daily requirement of
32.4 cfs. The projected 2002 total raw water ICqUirement for this
analysis is 10, 100 acre-feet, with a maximum daily requirement of
36.1 cfs,
3. Ana1ysis of Adequacy of En&lewood's Senior Wa~r Rights
The analysis then compares, on a daily basis, the total availability of
Englewood's senior river rights, together with the City's senior
McBroom Ditch right, with the City's 2002 daily water requirement.
All of the City 's changed Nevada Ditch, Brown Ditch, and McBroom
Ditch rights are used in the "single-use" mode, because this mode
maximizes the water availability for the City's domestic use. The
analysis calculates on a daily basis any shorta&c in the City's supply,
and these short.ages are summed into the monthly shortaees depicted
in Table 1.
Column 1 of Table 1 indicates that En,lewood' s senior rights will
begin to fail to supply the City with its domestic water requirement in
the month of June, and that shortages will continue throu&h the month
of November, totiling some 343 acre-feet for the year.
Column 2 represents the reduced shortages which may be expected as
a result of Englewood's invocation of a relatively recent a2feement
with Denver Water . This agreement provides that Denver will
provide water to Englewood to compensate the City for short.tges in
her senior river rights which are attnoutable, in part, to evaporation
from Denver's Eleven-Mile Reservoir in South Park. The agreement
limits Denver's provision of water to Englewood to no more than 750
acre-feet in any year.
4. Solutions to Englewood's Shortages
Englewood has three means by which to eliminate shortages in her
supply for the year 2002. These include (a) drawing water from
Mclellan Reservoir~ (b) utilizing the Bear Creek augmentation plan
which requires a lesser amount of water from McLellan Reservoir;
and (c) diverting reusable wastewater return flows from the river.
2
20~2 OG /06 KON 1G:4G FAX 3033262624 MARTIN AND WOOD WATER ~~~ Englewood Ut111t1e& Ill 004 /010
a. McLellan Reservoir
To eliminate shortages from the City's senior water rights, the
City may simply withdraw water from McLellan Reservoir and
run it down City Ditch for delivery to the City's Allen Filter
Plant.
b. Bear Creek Augmentation Plan
The City some years ago obtained a decree from the W~r
Coun approving the City's right to divert from Bear Creek at
the McBroom Ditch and to augment such diversions when the
diversion are out-of-priority. At this time, it appears that
augmentation of such diversions will be required for the
remainder of year 2002 because of senior calls on the river.
The City has also constructed a pipe from the McBroom Ditch
diversion from Bear Creek all the way to the City 1 s river
reservoir located along the river at Union Avenue. Thus, the
City now has the physical means by which to deliver Bear
Creek water to the Allen Filter Plant.
When the City uses her Bear Creek augmentation plan, she
must place water in the river in the amount of that pa.rt of the
diversion which does not return to the river. In the summer,
due to much use of water for irrigation, the amount which the
City must place in the river -i.e., the augmentation amount -
may equal two-thirds of the diversion. Thus, if the City were
to divert 3 cfs from her Bear Creek rights, she would have to
place 2 cfs in the river. For the year 2002, the City would
likely take this 2 cfs from McLellan Reservoir and place it in
the river.
Using the above example, if the City needed 3 cfs, the City
could either (1) rake 3 cfs directly from Mclellan Reservoir,
or (2) the City could take 3 cfs from Bear Creek, ind take 2
cfs from McLellan Reservoir and place the 2 cfs in the river.
Thus, the augmentation plan allows the City to use the same
amount (3 cfs) for her domestic needs, while reducing the
amount of water needed from McLellan Reservoir.

c. Diversion of Reusable Return Flows
Both the City of Englewood and Centennial Water and
Sanitation District own and use reusable water . When reusable
water is used, the return flows (treated wast.ewat.er and
irrigation rerum flows) may again be diverted and used.
Much of Centennial' s water supply derives from .reusable
sources which result in reusable return flows accruing to the
river upstream from Union Avenue. Cent.ennial's decreed
augmentation plan allows for the quantification of such
reusable return flows and for Englewood to divert like amounts
at Union Avenue . To the ext.ents (1) that Cent.ennial ha&
reusable return flows which are surplus to Ccntcnnial's
augmentation plan and (2) that Centennial grants Englewood
pennission to divert its reusable rerurn flows, this source of
water may help to eliminate shortages in En&lewood' s year
2002 water supply .
While the diversion of such reusable return flows may prove
helpful in eliminating shortages, such opportunities for
En&lewood to divert this source may occur during periods of
very low river flow with attendant poor water quality . If any
agreement is made between Centennial and Englewood
regarding Englewood's diversion of Centennial' s reusable
retum flows , Englewood should have the option to elect in her
sole discretion whether to divert such water.
II. En&Iewood's Provision of Water to Centennial in Year 2002
A. Current Water Supply Agreement
En&lewood has for several years been providin~ water to Centennial under a
temporary agreement . This agreement provides that Englewood will supply
Centennial with 1 1500 acre-feet per year on a designated monthly schedule,
and that Centennial will pay Englewood for such wat.er at a relatively high
price . The agreement also provides that Englewood will supply Centennial
with if-and-when water beyond the scheduled 1,500 acre-feet, and that if
Centennial. elects to purchase such if-and-when water, Centennial will pay
Englewood for such water at a relatively low price .
For several years Englewood has provided Centennial with the 1,500 acre-
feet of high priced scheduled water and also with varying amounts of lower-
priced water .

Table 2 swmnarizes the likely sources of Englewood's proVlSl.on to
Centennial of the 1,500 acre-feet of scheduled water. Englewood is expected
to provide 1,535 acre-feet to Centennial in the year 2002.
To date, Englewood has supplied Centennial with approximately 300 ac.rc-
feet.
Englewood will receive from Denver Wat.er her 40 % of the Ranch Creek
Basic Delivery which amounts to 520 acre-feet.
Englewood will receive no Ranch Creek Paid Delivery water from Denver
Water in 2002.
Englewood's agreement with Thornton and Westminster will provide at least
75 acre-feet. The agreement provides fo.r a delivery to Englewood of
between 75 and 450 acre-feet, so the delivery may be more than 75 acr~feet,
although with this dry year, only 75 acre-feet can be counted upon.
Englewood's Boreas Pass Ditch is expected to provide approximately 100
acre-feet.
Englewood's LF-M2 Well is a deep Denver Basin aquifer well located above
Mclellan Reservoir. Because of the banking provisions in its Water Court
decree , this well has some 1,000 acre-feet banked for furure use. The well
pumps at a rate of approximately l cfs, or 2 acre-feet per day, or 60 acre-
feet per month. This well is pumping continuously now, and for the last
eight months of the year (May -December), it is expected to produce
approximately 480 acre-feet.
Englewood's interests in the Guiraud and Demmick Ditches are expected to
produce approximately 60 acre-feet
It is import.ant to note in the contexts of Englewood's year 2002 shortqe
and Englewood's ability to provide Centennial with 1,500 acre-feet of
high-priced sclleduled water, that Englewood currently hti 2,100 acre-
feet of water stored in Mcl.ellan Reservoir.
ill. Outlook for Next Year-Year 2003
A. Englewood Water Supply
If a drought like that of 1954 were to continue through the year 2003, one
would expect that En&lewood 1 s senior rights would minimally fall short of
5

satisfying the City's domestic needs to about the same extent as shown in
Table 1. Again the City's solutions would probably be to use the Bear Creek
augmentation plan and/or water from Mclellan Reservoir.
B. Englewood provision of Water to Centennial
One would expect the pendin& water and facilities lease with Centennial to be
initiated by the beginning of the year 2003. Like the temporary a&reement
with Centennial, the pending lease also provides for Englewood to deliver to
Centenni.a.1 1 ,500 acre-feet of relatively high·priced water.
Table 2 can fairly be used to depict the sources of water which Englewood is
expected to have for delivery to Centennial, with few changes.
Englewood's 40 % of Ranch Creek Basin Delivery water will remain at 520
acre-feet. Per agreement with Denver Water, it may be larger than 520 acre-
fcet, but i t can 't be smaller.
The Standley Lake, Boreas Pass , and Guiraud/Demmiclc sources are
expected to remain the same, and one should disregard year 2002' s 300 acre-
feet delivered to date .
After the year 2003 the banked water available to the LF-M2 well would be
exhausted, or nearly exhausted, and it would thereafter be limited to
approximately 127 acre-feet per year . For this and other reasons ,
Enilewood should consider the construction of at lease one additional deep
Denver Basin aquifer well. Englewood has some 3 ,000 acre-feet per year
decreed to such wells, and because the decrees were entered ten years ago ,
Englewood has some 30,000 acre-feet banked and available for drought use,
if a well(s) is constructed and ready for use.
The sum of the sources for year 2003 is 1,475 ac1e-feet. The minor
difference of 25 acre.feet from the 1,500 acrc·fcct delivery figure could
come from Englewood 's water in McLellan Reservoir.
IV. Englewood's Water Quality
When the river flow at Union Avenue is low, the river's water quality frequently is
poor, and in turn Englewood's treated water frequently is subject to taste and odors.
The amount of water released to the river from Chatfield Reservoir eenerally
governs the amount of river flow at Union Avenue. In past years very little flow
has been released to the river in the winter. Typically, in January or February,
Chatfield Reservoir has filled, and increased releases to the river then occur, and
water quality improves. During other times of the year, releases from Chatfield
6

Reservoir have generally been large enough so that En1Iewood has not suffered
water quality problems.
Recently Englewood has suffered taste and odor in her drinking water, because
releases from Chatfield reservoir to the river have been very low. For the following
reasons Englewood is expected to suffer poor raw water quality more in the future
than in the past.
Denver Water owns water storaee riehts in Chatfield Reservoir. Pursuant to
Federal requirements, Denver is obligated to maintain a flow in the river between
its Strontia Springs Reservoir and Chatfield Reservoir of 30 cfs in the winter, and
60 cfs in the summer. Frequently, these flows would not naturally be in the river,
so Denver releases water from its upstream reservoir (Cheeseman, 11-Mile, Antero,
and Strontia Springs) and supplements the fl.ow in the Strontia Springs-to-Chatfield
reach to maintain the required 30 or 60 cfs flows. Denver then recaptures these
storage releases in Chatfield Reservoir .
While Denver is recapmring these storage releases in Chatfield Reservoir, and
otherwise storing water in Chatfield Reservoir, frequently there is little water
released from Chatfield Reservoir to the river, sometimes causing water quality
prob1cms for En21ewood. But , this recapture can't go on forever. Chatfield slowly
fills up, and then it begins to spin Denver's waier into the river. This has typically
occurred in January and February .
For years Denver has been considering a physical hookup between Chatfield
Reservoir and its Conduit 20 which runs to Denver's Marston Water Treatment
Plant. Conduit 20 runs a little west of Chatfield Reservoir and this plan would
require both passage of water through Chatfield Dam and then a pump station a pipe
line to Conduit 20 . Denver has ownership interests in Nevada Ditch and Last
Chance Ditch and presumably would use these ownership interests to convey its
water through the dam . Then Denver would need to build the pump station and
pipeline to get water to Conduit 20 .
Once Denver puts this .Plan into effect, it would be able to re-recapture the storage
releases which it must provide to maintain the river flow of 30 or 60 cfs down to
Chatfield Reservoir. To the extent that Denver is able to re-recapture these storage
releases and run them to the Marston Plant for treaanent, the fillin2 of Chatfield
Reservoir will take longer, and the result will be a more prolonged period of little
or no release of water from Chatfield Reservoir to the river. Thus, Englewood
should expect mare prolonged periods of poor water quality in the river at Union
Avenue .
