INTRODUCTION
This 2020 Update to the Town of Fraser Water Supply Plan (“Updated Water Plan”) is
primarily intended to provide a “picture in time” of the current legal and physical water supplies
available to the Town of Fraser (the “Town”), in its role as a municipal water supplier. It is
hoped and intended that the Updated Water Plan will be useful to the Town Board in decision-
making and policy determinations regarding water supply issues, and as a resource to evaluate
future potential growth and development; to the Town Staff, as a reference source for planning
efforts, which identifies both the current limitations and future growth potential of the municipal
water system; and to current and future, potential residents and business owners in the Town,
who may be interested in a better understanding of the Town’s water supplies.
The Updated Water Plan relies heavily upon, and is generally intended as an update to,
prior water supply planning efforts undertaken by the Town, including efforts in 2007 (resulting
in a draft “Water Supply Master Plan” report, primarily prepared by Brown & Caldwell), and in
2015 (resulting in the draft “Fraser Firming Project Study” report prepared by HRS Water
Consultants, Inc. (“HRS”) and JRS
Engineering Consultant, LLC), and less
formal efforts by the Town Staff and its
water team over the years. Preparation of
the Updated Water Plan was a
collaborative effort involving input from the
Fraser Town Board of Trustees; the Fraser
Town Staff; HRS; and the Town’s water
rights counsel.
The Town’s municipal water supply
facilities include two independent, but
physically connected, systems: (1) the
“North System”, which generally supplies geographic areas of the Town known as “Old Town
Fraser”, and the Byers Peak Properties development; and (2) the “South System” which
supplies geographic areas of the Town encompassing the Rendezvous and Grand Park
developments.
This report is divided into two sections. The first section is a general description of the
current legal water supplies for both the North and South Systems. The second section
discusses the current and projected future water supply demands, and physical supplies for
both the North and South Systems.
I. Current Legal Water Supplies for the North and South Systems
A. LEGAL WATER SUPPLIES FOR THE NORTH SYSTEM
i. Town of Fraser’s Alluvial Well Field (Domestic Water Supply)
The North System includes a well field of nine decreed wells (the “Fraser Wells”) with
appropriation dates of 1982 and 1985. (See Table 1, North System Wells). As described in more
detail below, pursuant to various Water Court decrees, the Fraser Wells operate as alternate
points of diversion for more senior surface water rights owned by the Town, and are “exchange
to” structures for the Town’s decreed exchanges. Additionally, the Town owns and will operate
in the future, a decreed plan for augmentation that covers out-of-priority depletions from Fraser
Well Nos. 1 and 2.
(1) Fraser Wells as Alternate Points of Diversion for Fraser
Domestic Water System
The original legal source for Fraser’s “domestic water system” was decreed absolute in
Civil Action 1175 for 2.28 cfs with an appropriation date of September 12, 1954 and an
adjudication date of January 14, 1957 (the “Fraser Domestic Water Supply System”). The
Fraser Domestic Water Supply System water right is decreed for domestic and municipal
purposes, including irrigation and fire protection. In Civil
Action W-2279, the original point of diversion on St.
Louis Creek for this water right, was changed to the
Gaskill Ditch Headgate. Later, in Case Nos. 82CW219
and 85CW339, the Town’s alluvial wells were decreed
as alternate points of diversion for the Fraser Domestic
Water Supply System water right. This water right was
in use for municipal and domestic use prior to October
1977 and, therefore, is covered by augmentation or
replacement releases from the Historic Users Pool, or
“HUP”, in Green Mountain Reservoir.
(2) Well Nos. 1, 2, 3(a), 3(b), 4, and 5
In Case No. 82CW219, Fraser Well Nos. 1, 2, 3(a), 3(b), 4, and 5 were decreed
conditional with an appropriation date of July 22, 1982 and an adjudication date of July 5, 1985.
Well Nos. 1-5 were decreed for irrigation, domestic, industrial, and all other municipal purposes.
These wells were also decreed as alternate points of diversion for the Town’s Domestic Water
System. Under the decree in Case No. 82CW219, the total amount of water produced by any
well or any combination of wells shall not exceed 2.28 cfs, when the wells are being pumped as
alternate points of diversion. This is an important limitation on the legal water supply available
to the North System. Additionally, when the wells are being used as alternate points of
diversion, the total amount of water produced by any well or any combination of wells shall not
exceed the amount of water available in priority to the Fraser Domestic Water System at its
decreed point of diversion.
Fraser Well Nos. 1 and 2 are covered by the plan for augmentation approved in Case
No. 83CW362 on May 27, 1987 (the “Forest Meadows Augmentation Plan”), as described in
more detail in Section I.A.v., below.
(3) Well Nos. 7, 8, and 9
In Case No. 85CW339, Fraser Well Nos. 7-9 were decreed conditional with an
appropriation date of February 28, 1985 and an adjudication date of November 8, 1988. Fraser
Well Nos. 7-9 were decreed for irrigation, domestic, industrial, and all other municipal purposes.
Like Fraser Well Nos. 1-5, Fraser Well Nos. 7-9 were designated as alternate points of diversion
for the Fraser Domestic Water System. Again, when the wells are being used as alternate
points of diversion, the total amount of water pumped from any well or combination of wells shall
not exceed 2.28 cfs, and the total amount of water produced by any well or any combination of
wells shall not exceed that amount of water available in priority to the Fraser Domestic Water
System water right at its decreed point of diversion, less any stream losses, from the point of
diversion to the well locations.

ii. Surface Water Rights
(1) St. Louis Creek Ditch Enlargement and Extension
The St. Louis Creek Ditch Enlargement and Extension was decreed for irrigation
purposes in Civil Action 183 with an appropriation date of June 1, 1904 and an adjudication date
of August 3, 1911. The Town owns 1.0 cfs, absolute, to divert from St. Louis Creek. The water
right was originally decreed for irrigation. In case number W-2280, this water right was changed
from its original use to the following new uses: domestic, fire and sanitary, garden and lawn
irrigation, and other household uses. Additionally, the point of diversion was changed to the
Gaskill Ditch Headgate. The St. Louis Creek water right is not currently connected to the Town’s
municipal water supply system; however, the Town continues to evaluate the possibilities for
physically incorporating the water available under these senior water rights into its daily water
supplies (see, for example, the “Fraser Firming Study Project” report, referenced above), and
anticipates and intends such use in the near future.
(2) Elk Creek Ditch No. 2
The Elk Creek Ditch No. 2 surface water right was decreed in Civil Action 407 on August
11, 1906 for 2.0 cfs, absolute, to divert out of Elk Creek for irrigation. Pursuant to the terms of
the Water Court decree approving the Forest Meadows Augmentation Plan, one cfs of the Elk
Creek Ditch No. 2 water right was abandoned to Elk Creek, and one cfs was changed to
“storage use for subsequent augmentation release.” Fraser intends to utilize the Elk Creek Ditch
No. 2 water right in the future for the decreed augmentation use, and is currently evaluating
various water storage options.
iii. Replacement Water Sources and Contract Rights
(1) Middle Park Water Conservancy District Allotment Contracts
The Town has four water allotment contracts for Windy Gap Project water with the
Middle Park Water Conservancy District (“MPWCD”). Two water allotment contracts are for
water stored in Granby Reservoir, and two are “Windy Gap Standby Contracts” for water stored
in Wolford Mountain Reservoir. Through all four contracts, the Town currently has leased
157.75 af of Windy Gap Project water. Sixty-five af of that amount currently is subject to a lease
to the developer of the Grand Park property.
The specific contracts are described in the following subsections.
(a) Twenty-Five AF of Windy Gap Project Water Stored in
Granby Reservoir
Pursuant to a July 11, 1985 water allotment contract with MPWCD Fraser is entitled to
25 af of Windy Gap Project water stored in Granby Reservoir, which is located on the Colorado
River upstream of the confluence of the Colorado and Fraser Rivers. This water allotment
contract is perpetual. An exchange of this water from the confluence of the Fraser and Colorado
Rivers to the Fraser Wells was decreed in Case No. 85CW337, Water Division 5. This 25 af
may be available for use by Denver Water as replacement water, pursuant to various
agreements among the Town, other Grand County water suppliers, and Denver Water, pursuant
to which Denver Water bypasses water available for diversion through its Moffatt Collection
System.
(b) Eighty AF Stored in Granby Reservoir
Fraser is entitled to 80 af of Windy Gap Project water stored in Granby Reservoir
pursuant to an August 1, 1989 water allotment contract with MPWCD. This water allotment
contract is perpetual. Under a July 10, 1989 Lease Agreement, 65 af of the 80 af has been
leased for potential irrigation of a golf course planned, at one time, for the Grand Park
development. This 80 af of water is also the subject of a decreed exchange. Pursuant to the
decree in Case No. 90CW235, Water Division No. 5, this water can be exchanged to various
locations in the Fraser System and Maryvale System. The 15 af not being leased, may be
available for use by Denver Water as replacement water.
(c) Windy Gap Project Water Stored in Wolford Mountain
Reservoir
Additionally, Fraser is entitled to 52.75 af of Windy Gap Project Standby water stored in
Wolford Mountain Reservoir pursuant to two water allotment contracts entered in 2003 and
2004 (“Standby Water”). The Wolford Mountain Reservoir is located on Muddy Creek, which is
tributary to the Colorado River downstream of the confluence of the Colorado and Fraser
Rivers. These two contracts are perpetual and presumably valid if the Town maintains its other
MPWCD Windy Gap Contracts. The Standby Water may be available for use by Denver Water
as replacement water.
(2) Clinton Reservoir-Fraser River Water Agreement
Fraser is a party to the Clinton-Reservoir-Fraser River Agreement (“Clinton Reservoir
Agreement”), which was signed on July 21, 1992 and amended on October 26, 2016. Pursuant
to the Agreement, Denver Water agreed to annually bypass at its intakes and make available
from other components of Denver Water’s delivery system, as necessary, 846 af of water to be
used under the provisions of the Clinton Agreement and Grand County Water Users’ Operating
Plan (“Bypass Water”). The Town is entitled to 104.5 af of the Bypass Water.
By decree in Case No. 92CW305, entered on November 19, 1996, Grand County Water
& Sanitation District No. 1, Winter Park Water & Sanitation District, the Town of Granby, and the
Town of Fraser (“Co-Applicants”) sought and were awarded a conditional water right and
approval of a plan for augmentation, including substitution and exchange to implement the
provisions of the Clinton Agreement. Pursuant to the original decree and subsequent diligence
decrees, water will be diverted under a 1992 priority at Denver’s existing points of diversion and
collection system and will be released from Denver’s collection system on the Fraser River, St.
Louis Creek, Little Vasquez Creek, and Vasquez Creek into those streams and used by each of
the Co-Applicants at locations decreed to each of those entities under their existing water rights.
Pursuant to the decree, the Bypass Water can be used for irrigation, domestic, and all municipal
uses between September 15 and May 15 each year, but it is not decreed for storage. The
seasonal limitation on the use of Bypass Water was eliminated in connection with the CRCA
agreements described immediately below.
(3) Colorado River Cooperative Agreement
On September 23, 2010, Denver Water and seventeen entities from the West Slope
executed the Colorado River Cooperative Agreement (“CRCA”), which resolves various
longstanding disputes involving Denver Water’s operations on the West Slope. The CRCA took
effect on September 26, 2013. Pursuant to the CRCA and the 2012 Grand County Water Users
Operating Plan (“GCWUOP”), Denver Water agreed to make 375 af of water available annually
to the Grand County signatories (“Additional Bypass Water”), “upon issuance and acceptance
by Denver Water of permits necessary for [Denver Water’s] Moffat Project.” Pursuant to the
GCWUOP and the related “Implementation Agreement” between Denver Water and the Town,
executed on October 9, 2013, the Town is conditionally entitled to 68.75 af of the Additional
Bypass Water.
Pursuant to the decree entered on March 15, 2016 in Case No. 11CW152, the Additional
Bypass Water may be used for municipal, snowmaking, domestic, commercial, irrigation,
recreation, fish and wildlife, and fire protection uses. The Additional Bypass Water may be
delivered for diversion to Fraser at the following locations: Gaskill Ditch; Fraser Well Nos. 1, 2,
4, and 5; and Elk Creek Ditch No. 2. Prior to diverting the Additional Bypass Water through its
wells, pursuant to the decree in Case No. 11CW152, Fraser will need to apply for and obtain
new well permits to allow for diversion of deliveries of the Additional Bypass Water.
iv. Storage – Reservoir No. 2
In Case No. 02CW367, on February 28, 2005, the Grand County Water & Sanitation
District (“GCWSD”) decreed GCWSD Reservoir No. 2 (“Reservoir No. 2”) for municipal,
irrigation, augmentation, piscatorial, aesthetic, and recreation uses with the right to fill and refill
in priority to replace water applied to decreed uses and to replace evaporative losses. The
Reservoir No. 2 water right was originally decreed for 80 af, conditional. This reservoir is an off-
channel, lined reservoir located southwest of the Fraser River between the Maryvale Wells and
the Fraser Wells.
On July 31, 2018, the Town acquired from GCWSD No. 1, via deed, 25 af of the
Reservoir No. 2 water right and 25 af of the storage capacity in the reservoir. GCWSD No. 1
also conveyed 25 af of the water right and 25 af of the storage capacity to Winter Park Water &
Sanitation District (“WPWSD”). In Case No. 18CW3070, 70 af of this water right was decreed
absolute for all decreed purposes with 10 af remaining conditional. GCWSD No. 1 owns the
remaining 20 af of the Reservoir No. 2 water right and storage capacity.
WPWSD, GCWSD, and Fraser executed an operating agreement for Reservoir No. 2 on
July 30, 2018.
v. Forest Meadows Plan for Augmentation
As described above, the Forest Meadows Augmentation Plan was decreed in Case No.
83CW362 on May 27, 1987. Pursuant to the approved augmentation plan, one cfs of the Elk
Creek Ditch No. 2 water right was abandoned to Elk Creek, and one cfs was changed to
“storage use for subsequent augmentation release.” Additionally, the plan is approved to
provide replacement for out-of-priority depletions caused by the pumping of Fraser Well Nos. 1
and 2 for domestic, commercial, municipal, and irrigation uses. Fraser continues to investigate
options for the construction of an augmentation pond to enable operation of the Forest
Meadows Augmentation Plan. Pursuant to the terms of the Case No. 83CW362, a decreed
storage pond for the Elk Creek Ditch No. 2 water, is required to implement the augmentation
plan.
B. LEGAL WATER SUPPLIES FOR THE SOUTH SYSTEM
The following sections describe the legal water supplies for the South System:
i. Maryvale Augmentation Plan
The Regis Maryvale Plan for Augmentation (“Maryvale Augmentation Plan”) was
decreed in Case No. 86CW258 and amended in Case No. 98CW401. It generally provides for
the augmentation of water uses associated with the Rendezvous/Grand Park properties.
Pursuant to the Amended and Restated Annexation Agreement between Fraser and
Rendezvous Colorado, LLC (“Amended Annexation Agreement”), dated June 23, 2000, the
Maryvale Augmentation Plan was conveyed, in large part, to the Town via Bargain and Sale
Deed, dated June 23, 2000, and corrected on October 17, 2011 (the “Deed”). Among other
rights, the Deed conveyed to Fraser 1.675 cfs of the Cozens Ditch water right; 20 af of the
“Mary’s Pond” storage water right; 32.7 af of storage in augmentation/detention ponds located
on Grand Park (the “Detention Reservoirs”); and “all of the benefits and burdens” of the
Maryvale Augmentation Plan.
The Maryvale Augmentation Plan provides for augmentation of 16 large capacity wells
(1,600 gpm total) and 91 small capacity wells (maximum pumping rate of 15 gpm) to serve
2,822 equivalent residential units (“EQRs”) and irrigate 17 acres. The primary source of
augmentation supply under the Maryvale Augmentation Plan
is the 3.125 cfs Cozens Ditch water right, which was
historically used for the irrigation of 125 acres, and changed
for augmentation use. The changed water right is used for
augmentation of domestic, municipal, and irrigation uses
either directly or by release from storage.
Prior to full build out of the development, the decree
contemplates enlargement of the existing Maryvale Reservoir
and the construction of up to six of the Detention Reservoirs
to store excess historical consumptive use credit water and winter return flows. The 32.7 af of
storage capacity in the Detention Reservoirs required for full operation of the Augmentation Plan
was conveyed to Fraser by the Deed.
ii. Wells
The South System includes a well system with three decreed well fields. One well field
has been partially developed , and currently includes four active wells, which supply water to
development on the Rendezvous and Grand Park properties. See Table 2 (“South System
Wells”). These four wells were constructed in the Troublesome Formation, which is considered
tributary to the Fraser River. Out-of-priority stream depletions from these wells are fully covered
by operation of the Maryvale Augmentation Plan.
(1) Maryvale Well Nos. 1, 2, and 3
By decree entered on December 31, 2002 in Case No. 99CW313, the Court adjudicated
three of the 16 proposed large capacity wells covered by the Maryvale Augmentation Plan.
These wells are known as Maryvale Well Nos. 1, 2, and 3. The maximum cumulative diversions
from the Maryvale Well water rights plus the Rendezvous
Well Field Nos. 1-3 water rights decreed in Case No.
00CW294, may not exceed 3.57 cfs (1,600 gpm), with a
total annual volumetric limit of 892.4 af, as specified in the
Maryvale Augmentation Plan.
The amount claimed for each individual Maryvale
Well is 0.5 cfs (225 gpm). Maryvale Well Nos. 1-3 are
decreed for domestic, irrigation, commercial, industrial,
municipal, stockwatering, and fire protection uses. Pursuant to the Deed, 0.78 cfs cumulative of
the Maryvale Well Nos. 1, 2, and 3 water rights was conveyed to Fraser for use in Fraser’s
municipal water supply system.
Maryvale Well No. 1 was decreed absolute for 0.19 cfs (85 gpm) for domestic, irrigation,
and commercial purposes in Case No. 08CW192. The remaining conditional amount is 0.31 cfs
(139 gpm) for domestic, irrigation, and commercial purposes and 0.5 cfs (225 gpm) for
industrial, municipal, stock watering, and fire protection purposes.
The Town and Grand Park/Rendezvous recently filed a claim to make an additional
portion of the Maryvale Well No. 1 water right absolute for municipal purposes in the amount of
0.20 cfs That claim, filed in Case No. 19CW3020, is pending.
(2) Rendezvous Well Fields 1, 2, and 3
By decree entered on December 31, 2002 in Case No. 00CW294, the Court adjudicated
13 of the 16 large capacity wells covered by the Maryvale Augmentation Plan in three well fields
(“Rendezvous Well Field Nos. 1, 2, and 3”). As mentioned above, the maximum cumulative
diversions from the Rendezvous Well Field water rights plus the Maryvale Well Nos. 1-3 water
rights decreed in Case No. 99CW313, may not exceed 3.57 cfs (1,600 gpm), with a total annual
volumetric limit of 892.4 af, as specified in the Maryvale Augmentation Plan. The amount
claimed for each well within the Rendezvous Well Fields is up to 0.56 cfs (250 gpm).
In Case. No. 08CW191, three wells were utilized to make a total of 0.57 cfs (255 gpm) of
the Rendezvous Well Field No. 3 water right absolute for domestic, irrigation, and commercial
purpose as follows: Maryvale Well No. 4 for 0.99 cfs (40 gpm); Maryvale Well No. 5 for 0.29 cfs
(130 gpm); and Maryvale Well No. 7 for 0.19 cfs (85 gpm).
The total amount made absolute to date between all groundwater rights decreed in Case
Nos. 99CW313 and 00CW294 is 0.76 cfs (341 gpm) for domestic, irrigation, and commercial
purposes with a total volume of 96.33 af.
The Town and Grand Park/Rendezvous recently filed a claim to make additional portions
of Maryvale Well Nos. 4, 5, and 7 absolute for municipal use for a total of 0.60 cfs (270 gpm) as
follows: Maryvale Well No. 4 for 0.11 cfs (47.3 gpm); Maryvale Well No. 5 for 0.30 cfs (135.7
gpm); and Maryvale Well No. 7 for 0.19 cfs (86.5 gpm). That claim, filed in Case No.
19CW3034, is pending.

Grand County District Court in the amount of 3.125 cfs from Vasquez Creek for irrigation.
Historically, the Cozens Ditch Water Right was diverted from May through August for the
irrigation of approximately 125 acres. As mentioned above, the Cozens Ditch water right was
changed in Case No. 98CW41 to be used for augmentation purposes under the Maryvale
Augmentation Plan. By the Deed, 1.675 cfs of the Cozens Ditch water right was conveyed to the
Town.
(2) Cozens Ditch Enlargement and Extension
In Case No. 99CW314, on December 31, 2002, the Cozens Ditch Enlargement and
Cozens Ditch Extension water rights were adjudicated in the amounts of 3.1 cfs and 1.5 cfs,
respectively, for domestic, irrigation, commercial, industrial, stockwatering, fire prot ection,
storage in the Detention Reservoirs, and supplemental irrigation of 125 acres. The Cozens Ditch
Enlargement and Cozens Ditch Extension water rights were decreed to be used in conjunction
with the Maryvale Augmentation Plan.
By decree entered on June 16, 2019 in Case No. 18CW3144, 1.76 cfs of the Cozens
Ditch Enlargement water right and 1.5 cfs of the Cozens Ditch Extension water right were made
partially absolute for irrigation use.
iv. Reservoir/Pond Storage
(1) Mary’s Pond
A main source of augmentation releases for the South System is the Maryvale Reservoir
(aka “Mary’s Pond”), which was decreed in Case No. W-462 on April 10, 1972 for 32.58 af for
domestic, recreation, irrigation, and fish culture uses. Mary’s Pond was later decreed for
augmentation use in Case No. 86CW258 (superseded by the decree in Case No. 98CW041).
The Maryvale Augmentation Plan contemplates a 16 af enlargement of Mary’s Pond and
storage of water from the Cozens Ditch in Mary’s Pond for augmentation releases. The Town
acquired 20 af of the Mary’s Pond storage water right, via the Deed.
On September 4, 2015, Rendezvous/Grand Park and the Town entered into a “Grant of
Easement and Augmentation Pond Joint Operations Agreement,” which sets forth the parties’
agreement and respective obligations regarding the joint operation of Mary’s Pond. Express
provisions of this agreement anticipate that the Town and Grand Park will enter a similar
easement and operations agreement relating to operation by the Town of the Detention Ponds
on Grand Park, for augmentation use under the Maryvale Augmentation Plan.
The current active water storage capacity of Mary’s Pond is approximately 14 af.
Releases from Mary’s Pond are currently the primary source of augmentation water for out-of-
priority depletions associated with operation of the Maryvale Wells.
(2) Detention Pond Storage Rights
The final decree entered on December 31, 1999 in Case No. 99CW315 adjudicated
storage rights for ten detention reservoirs: Maryvale K-1a Reservoir, Maryvale K-1b Reservoir,
Maryvale K-2 Reservoir, Maryvale J-2 Reservoir, Maryvale J-3 Reservoir, Maryvale E-F
Reservoir, MR-1 Reservoir, MR-2 Reservoir, MR-3 Reservoir, and MR-4 Reservoir. The six
Maryvale Reservoirs (K-1a, K-1b, K-2, J-2, J-3, and E-F), referred to above as the Detention
Reservoirs, are contemplated as augmentation storage sites in the Maryvale Augmentation
Plan. Pursuant to the Maryvale Augmentation Plan, the Detention Reservoirs will be filled during
the summer under the Cozens Ditch water right, and excess consumptive use credits and winter
return flow water from the Cozens Ditch will be stored in the reservoirs. In the fall and winter, the
Detention Reservoirs will be drawn down in order to replace winter stream depletions.
The Detention Reservoirs are decreed conditional for irrigation, aesthetic, piscatorial,
recreation, municipal, commercial, industrial, and for augmentation and exchange. The
Detention Reservoirs are decreed in the cumulative amount of 36 af: K-1a (7.0 af); K-1b (5.0 af);
K-2 (10.0 af); J-2 (2.0 af); J-3 (6.0 af); and E-F (6.0 af).
Three of the Detention Reservoirs, K-1a, K-1b, and K-2, have been constructed, filled,
and put to beneficial use in the following amounts: K-1a (a series of three reservoirs with a total
capacity of 3.43 af) and K-1b and K-2 (one combined reservoir with a total capacity of 13.6 af).
These three reservoirs are currently operated by Grand Park, but will be operated for
augmentation purposes by the Town in the future. The three constructed reservoirs are located
in different configurations than originally decreed, and are more than 200 feet from their decreed
locations. The decree issued in Case No 08CW194 states: “[p]rior to making any of the subject
conditional water rights absolute, Applicants or their successors shall obtain a decree confirming
a change of location for any structure that is located at the originally decreed location.” Thus,
Grand Park/Rendezvous will need to file an application for change of water rights to reconcile
the as-built locations of the reservoirs with the decreed locations before seeking to make the
water rights absolute.
The Deed conveyed to Fraser 32.7 af of storage capacity in the Detention Reservoirs
required for operation of the Maryvale Augmentation Plan.
C. Other Water Rights
i. Decreed Exchanges
(1) Middle Park Windy Gap Exchange
In Case No. 85CW337, on October 2, 1989, a conditional right of exchange was
approved to allow the exchange of Windy Gap water from Granby Reservoir to the nine Fraser
Wells, which are the decreed “exchange to” locations. The exchange is decreed for 25 af,
conditional. No separate uses were decreed; rather, the uses are those already approved for
the Fraser Wells (i.e., irrigation, domestic, industrial, and all other municipal purposes). The
exchange allows diversion from the Fraser Wells, via exchange, when the water rights
associated with the Fraser Wells may not otherwise be in priority.
(2) Middle Park Exchange
In Case No. 90CW235, on June 8, 1995, a conditional right of appropriative exchange
was decreed for 80 af. The decreed exchange contemplates the exchange of Middle Park water
from Granby Reservoir to various “exchange to” locations that include Fraser Well Nos. 1, 2, 4,
and 5, the Gaskill Ditch, Wells RM-5, RM-6, and RM-7, Detention Reservoirs K-1a, K-1b, K-2, J-
2, J-3, E-F, and Mary’s Pond. Sixty-five af is currently leased to Rendezvous/Grand Park. No
separate independent uses were decreed; rather, the uses are those already approved for each
“exchange to” structure.
II. Physical Water Demands and Physical Supply
A. Current Water Supply Demand for the North System
i. Indoor Use and Irrigation Annual Volumes of Water per EQR
The North System supplies water generally to the “Old Town” Fraser area, and Byers
Peak Ranch (pursuant to an out-of-town service agreement) and, temporarily, a portion of the
Grand Park development. Table 3 is a current demand table, and includes indoor and outdoor
average and max day demands per EQR, total indoor and outdoor max day demands, and
indoor and outdoor annual volume demand estimates for the geographic areas currently served
by the North System.
In this analysis, Old Town Fraser’s and Byers Peak Ranch’s annual demand per EQR
are assumed to be the same. This demand is based on an assumption of 275 gallons per day
per EQR. Indoor average annual demand estimate for these areas is 0.308 af/ EQR. Irrigation
demand estimates are based on previous Brown & Caldwell water supply planning work for the
Town. In the Fraser area, the irrigation season
varies from year to year based on monthly
temperatures during the “shoulder months” of
the irrigation season. The irrigation season is
generally considered to begin in May and end in
September. Outdoor annual demand for the Old
Town Fraser’s and Byers Peak Ranch areas is
based on a 500 square foot lawn per EQR and
an irrigation application rate of 1.01 af per acre
(“ac”). These irrigation demand values result in
an annual irrigation demand of 0.012 af/ EQR.
The indoor and outdoor annual demands sum to
0.320 af/ EQR.
The Grand Park indoor average annual demand is 0.308 af/ EQR. This value is derived
from the Maryvale Augmentation Plan decree in Case No. 98CW41 (which is converted from
EQRs as defined in that decree). The irrigation season as defined by the 98CW41 decree is
May through September. The Grand Park outdoor annual demand is based on a 250 square
foot lawn per EQR with an irrigation application requirement of 1.387 af per ac. These irrigation
demand values result in an annual irrigation demand of 0.008 af/EQR. The indoor and outdoor
annual demands sum to 0.316 af/EQR.
ii. Average Annual Demand and EQRs
The North System currently serves a total of 962 EQRs, 184 of which are located in in
Grand Park. Based on these values and the “af/EQR” values above, the current Old Town
Fraser and Byers Peak Ranch annual indoor demand is 239.8 af/yr, and the current irrigation
demand is 9.0 af/yr. For the Grand Park area currently served by the North System, the current
annual indoor demand is 56.7 af/yr and the current irrigation demands is 1.5 af/yr. Thus, the
total current North System indoor demand is 296.6 af/yr and the total current irrigation demand
is 10.5 af/yr. The total current North System demand is 307.0 af/yr.
iii. Max Day Demands
The max day demand is a gpm water delivery rate and is estimated at 1.5 times the
average day demand. The wells, or future surface sources, which supply the North System
must be capable of delivering the max day water supply demand. Max hour demands are
supplied through water system tank storage. Max day demand during the irrigation season is
0.312 gpm per EQR. Current max day demand for the 778 EQRs in the Old Town Fraser and
Byers Peak Ranch areas is 242.9 gpm. Current max day demand for the 184 EQRs located in
the Grand Park area currently served by the North System is 56.0 gpm. Thus, the total current
max day demand for the North System is 298.8 gpm.
B. Current Water Supply Demand for the South System
i. Indoor and Irrigation Annual Volumes of Water Per EQR
The Town’s South System supplies water to Rendezvous and Grand Park which
comprise a geographic area located within the Town’s municipal boundaries. Table 4 is a
current demand table and it includes indoor and outdoor average and max day demands per
EQR, total indoor and outdoor max day demands, and indoor and outdoor annual volumes of
water currently required for the areas served by the South System. The South System indoor
average annual demand is 0.308 af/EQR. This value is taken from the Maryvale Augmentation
Plan decree issued in Case No. 98CW41. This decree also indicates that for purposes of
operating the Maryvale Augmentation Plan, the irrigation season is May through September and
the irrigation demand value is 0.008 af/EQR. The outdoor annual demand in the decree is
based on 250 square feet of lawn per EQR and 1.387 af/ac/yr. The indoor and outdoor annual
demands sum to 0.316 af/EQR.
ii. Average Annual Demand and EQRs
The South system currently serves 465 EQRs. Based on these values and the “af/EQR”
values above, the current annual indoor demand is 143.3 af/yr and the current annual irrigation
demand is 3.7 af/yr. These values result in a current annual demand for the South System of
147.0 af/yr.
iii. Max Day Demands
The South System max day demand values are derived from the Maryvale
Augmentation Plan decree. The average day indoor demand from the decree is 0.191
gpm/EQR and the average day irrigation demand is 0.012 gpm/EQR. The total average day
demand is 0.203 gpm/EQR. The max day demand is estimated at 1.5 times the average day
demand. The wells supplying the South System must be capable of delivering the max day
water supply demand. Max hour demands are supplied through water system tank storage.
Based on the irrigation season average day values and the 1.5 max day factor, the max day
indoor demand for the South System is 0.286 gpm/EQR. Based on the current 465 EQR total,
the current South System max day demand is 141.4 gpm.
C. Current Water Supply for the North System
i. Production Wells, Pumping Rates, and Safe Yield
The North System’s current water supply is from Fraser River alluvial wells.
Table 5 identifies the Fraser Wells and their current average pumping rates during two periods,
(1) spring and summer and (2) winter. The Fraser Well locations are shown on Figure 3. The
spring and summer wellfield pumping total is 735 gpm and the winter wellfield pumping total is
458 gpm. The difference is due to two wells (3b and 9) being utilized/available seasonally.
Table 5
Fraser Wells and Pumping Rates
Well Spring & Summer
Pumping Rates
(gpm)
Winter
Pumping Rate
(gpm)
1 120 120
2 78 78
3b 70 0
5 125 125
7 70 70
8 65 65
9 207 0
Total 735 458
The concept of “safe yield” with respect to the Fraser Well’s includes wellfield production
planning, such that the wells are capable of meeting Fraser’s max day demand. One aspect of
wellfield planning to achieve this goal is to have an installed wellfield capacity that exceeds the
current max day demand. The current safe yield plan is that the Fraser Wells will be equipped
with a total production capacity that is 100 gpm greater than the current max day demand. The
additional, safe yield, 100 gpm wellfield production capacity allows for well and well equipment
maintenance and repairs such that the North System will be able to meet max day demand
when one well is not operational.
As previously discussed, the current production capacity of the Fraser Wells is 735 gpm
in the spring and summer, and 458 gpm in the winter. Table 3 includes a current max day safe
yield demand of 399 gpm. These values demonstrate that the Fraser Wells can meet the
current max day safe yield demand. In the future, the 184 Grand Park EQRs currently served
by the North System will be served by the South System. When this transition occurs, the
Fraser Wells will obtain an additional 58.2 gpm of capacity to meet demands on the North
System. This capacity, and additional wellfield improvements, will be required to meet
development demands as projected into the future.
ii. Fraser Well Construction, Equipping, and Hydrogeologic Parameter
Data
The North System currently relies on seven wells to meet its daily water demands. Each
of these wells was constructed within the Fraser River alluvium. Table 6 provides an overview
of the hydrogeologic, construction, and equipping details for each of the Fraser Wells (both
active and inactive wells). This table was developed using available information from the
State’s well permit files, HRS report files, and information from the Town staff. The table
includes detailed information related to well construction, pump installation, tested and current
pumping rates, and recent water level data which was used to estimate saturated aquifer
thickness. Static water level data was provided by Town staff for each of the active wells.
These water levels were calculated based on measured water depth above the pressure
transducer and an assumed transducer depth setting near the pump intake.
D. Current Water Supply for the South System
i. Production Wells, Pumping Rates, and Safe Yield
The current water supply for the South System is from the Maryvale Well, which are
completed in the Troublesome Formations. Table 7 lists the Maryvale Wells and their current
pumping rates. The Maryvale Wells are numbered 1, 4, 5, and 7. The Maryvale Well locations
are shown on Figure 4. As noted in the comments column on Table 8, Well No. 6 is permitted
only as a monitoring well.
Table 7
Maryvale Wells and Pumping Rates
Well Pumping Rate
(gpm)
1 87
4 43
5 134
7 85
Total 349
The current combined production capacity of the Maryvale Wells is 349 gpm. Table 4
includes a current max day safe yield demand of 241.4 gpm. These values demonstrate that
the Maryvale Wells are capable of meeting the current max day safe yield demand. When the
184 Grand Park EQRs currently served by the North System, are permanently transitioned to
the South System, the South System’s safe yield max day demand will be 299.6 gpm (141.4
gpm + 58.2 gpm + 100 gpm). The current combined pumping capacity of 349 gpm for the
Maryvale Wells will be sufficient to meet this demand.
ii. Maryvale Well Construction, Equipping, and Hydrogeologic
Parameter Data
The South System currently relies on four active wells to meet its daily water demands.
Each of these wells was constructed in the Troublesome Formation which underlies the Fraser
River alluvium. Table 8 provides an overview of the
hydrogeologic, construction, and equipping details for
each of the Maryvale Wells (both active and inactive
wells). This table was developed using available
information from the State’s well permit files, HRS report
files and information from the Town staff. Table 8 also
includes detailed information related to well
construction, pump installation, tested and current
pumping rates, and static water level data which was
used to estimate the saturated thickness of the aquifer.
Static water level data were taken from well construction reports for each well, as water levels in
these wells are not monitored by Town staff.
E. Buildout Water Supply Demand by EQRs for the North System
i. Develop Build Out Demand Values by EQR for the North System
The estimated total number of EQRs at buildout for the North System is 4,863 EQRs.
The following EQRs are included in the buildout estimate: Old Town Fraser, Byers Peak Ranch,
and possible future annexations. Using these categories, the total number of projected, future
EQRs is: Old Town Fraser – 1,530 EQRs, Byers Peak Ranch – 1,233 EQRs, and future
annexations - 2,100 EQRs.
ii. Average Annual Indoor and Irrigation Demands
Table 9 provides the annual volume of water required at buildout for each of the areas
listed above. The values shown in Table 9 include: Old Town Fraser 489.4 af/yr, Byers Peak
Ranch 394.4 af/yr, and future annexation - 671.7 af/yr. The total annual buildout demand is
1,555.5 af/yr. The values on Table 9 show that the annual irrigation volumes required at
buildout are small percentages of the total annual demand.
iii. Max Day Demands
Table 9 also provides max day and safe yield max day demand estimates in EQRs
intervals by area. Safe yield max day demand values are obtained by adding 100 gpm to the
build out max day demand. The total max day demand of 1,577 gpm becomes a safe yield
demand of 1,677 gpm. The EQR estimates and their corresponding safe yield max day
demand pumping rates will be used to help determine and plan for future wells, water supply
infrastructure, and water rights acquisitions/strategies that will be required to meet the future
North System safe yield max day demands over time. The purpose of Table 10 is to track
Fraser wellfield installation, equipping, and maintenance work that will be required to meet
future North System demands. When additional wellfield pumping is required to meet demands,
a description of the well work to be performed and a cost estimate for the work will be entered
into the spreadsheet.
F. Buildout Water Supply Demand by EQR for the South System
i. Develop Build Out Demand Values by EQR for the South System
The estimated number of EQRs at buildout for the Rendezvous and Grand Park areas,
served by the South System, is 2,822 EQRs. This total EQR value is derived from the Maryvale
Augmentation Plan decree. The 2,822 EQR total includes the 184 EQRs currently served by the
North System, and 91 EQRs contemplated under the Maryvale Augmentation Plan decree to be
served by small capacity wells. Currently none of the 91 small capacity wells have been
constructed and it is not likely any of these wells will be constructed.
ii. Average Annual Indoor and Irrigation Demands Including Open
Space Irrigation
With a total EQR estimate of 2,822 EQRs, and an annual value of 0.316 af/EQR, the
total annual demand estimate for the South System is 892.4 af/yr. Of this total, 869.0 af/yr is for
indoor demand and 23.4 af/yr is outdoor irrigation demand.
iii. Max Day Indoor and Irrigation Demands
The total max day demand estimate during the irrigation season for 2,822 EQRs under
the South System is 858.2 gpm. This value is based on an indoor max day value of 0.286
gpm/EQR and an outdoor irrigation demand of 0.018 gpm/EQR. Table 11 provides demand
estimates in EQR intervals of approximately 200 EQRs. Safe yield max day demand values
were obtained by adding 100 gpm to the build out max day demand. The total max day demand
of 858.2 gpm becomes a safe yield demand of 958.2 gpm. The EQR estimates included in
Table 11 will be used to help determine and plan for the future wells and water supplies
infrastructure that will be required to meet the future demand to be served by the South System.
The purpose of Table 12 is to track installation of additional Maryvale Wells, equipping, and
maintenance work that will be required to meet future wellfield demands. When additional
wellfield pumping is required to meet demands, a description of the well work to be performed
and a cost estimate for the work will be entered into the spreadsheet.
CONCLUSION
Current and future water demand and supplies for Fraser’s North and South
Systems are discussed and quantified above in the Physical Water Demands and Supply
section of this report. Significant conclusions and recommendations from the above
discussions and work performed include the following:
1. Fraser’s North and South System wellfields have the capacity to meet current
safe-yield max day demands. The Future Demand to Buildout tables and spreadsheets
(see Tables 9 through 12) for the North and South Systems are based on incremental EQR
increases. The spreadsheets should be used in the Town’s water supply planning to
understand the max day water supply requirements of additional EQRs on the Town’s
water supply systems.
2. The Town should continue to promote and support water conservation,
particularly during the irrigation season.
3. Water supplies for additional development beyond the current demands
should be in place at least three months before the water is needed. This recommendation
may require that water supply development work begin no later than two years before the
water may be needed.
4. If Water Court applications are required to obtain new water rights or to
change the Town’s current water rights, this work should begin no later than three years
before the water is needed.
5. The Town should continue to monitor and record all well pumping and water
level data (both static and pumping levels).
6. Regular review of the water well production and water level data will be
important to determine when pumping equipment and well maintenance should be
performed. Pumping equipment should be removed from wells and inspected at
approximately five-year intervals. At this time a video survey of the well should be
performed and appropriate well rehabilitation work completed.
7. The onsite water supply potential should be evaluated for any new
annexation area.
8. The Town’s current augmentation storage is sufficient for its current water
supply demand. Additional augmentation storage will be necessary to meet future legal
and physical water supply requirements.
9. Accounting for both the North and South Systems should continue to be
updated on a monthly basis, and the Town should continue to work with the Colorado
Department of Water Resources staff with respect to water rights accounting matters.
10. The Town’s St. Louis Creek and Elk Creek surface water rights continue to
be important components of the Town’s future water supplies and planning efforts.
11. The Town should continue to evaluate possible water rights/storage acquisitions
that may arise in the future, to provide additional certainty and protection against increasing
demands and changing legal and climatological circumstances.
12. The Town should continue incrementally perfecting its conditional water rights
through the diligence and Water Court process. The Town should vigilantly protect its legal
water supplies by monitoring and prudently participating in Water Court proceedings potentially
impacting the Town’s water rights.
13. The Town should continue to be an active participant in all existing and future
water related agreements with third-parties, and proactively steer its water supply development
activities to maximize the benefits of those agreements (e.g., the Clinton Reservoir-Fraser River
Water Agreement, the Colorado River Cooperative Agreement).
