Upper Roaring Fork River Management Plan (Plan)
Gary provided the Plan's historical background and open space's goals for the project. OST has
been working cooperatively on this project since 2016. This is a shared project between the City
of Aspen and Pitkin County with OST and Healthy Rivers & Stream funding the County's share.
The project is a holistic examination of the upper Roaring Fork River valley from Independence
Pass to Jaffee Park. The project has morphed into a tool for all upper Roaring Fork River users,
water rights holders and municipalities to find ways to collaboratively work together to utilize
water efficiently, improve water quality, improve water flows and riparian health. DST's
objective is to glean insight on how our property management actions can best maintain the
health of the river. Today's presentation is for the OSTB to provide Plan comments and to
decide whether to recommend the BOCC to continue support of the Plan moving forward. There
are no budget impacts at this time. The Aspen City Council and Healthy Rivers & Streams Board
will also review the plan.
The Upper Roaring Fork River Management Plan Executive Summary is incorporated as part of
this record as `Exhibit A. '

April Long introduced and Seth Mason conducted the Plan's presentation. The Plan examines the
upper Roaring Fork River main stem and major tributaries to above Brush Creek; examines the
factors that contribute to the existing conditions; examines the physical and biological
relationships; relationship of flows and the flood plain; all these aspects in concert while
pursuing programmatic solutions that will enhance the river's health. Besides the scientific
aspects the Plan also brought together stakeholders and public input. The Roaring Fork River
stretch through the City of Aspen faces multiple threats. Within the City the stormwater outfalls
discharge into the river, the City is downstream from significant water diversions
(Transmountain diversions reduces flow by 40%), plus the City is built along the river's edge
causing a lack of riparian areas. Colorado Water Quality Control Division (CWQCD) designated
this stretch of the river as impaired. To meet river flow targets that could meet the existing flow
gaps and protect the river's aquatic ecosystems would need 4,000-acre feet of water above
Difficult Creek. (Visually, 4,000-acre feet would be about ten times the size of Grizzly
Reservoir) Stakeholder discussions included a variety of alternative actions; different utilization
and release schedules, programmatic opportunities, Salvation ditch agreements and how
alternative City storage could augment Salvation ditch needs, and non-diversion from City
ditches. The Plan's next phase work will utilize the developed data simulation tools to analyze
the river's needs while seeking action opportunities to meet those needs. Utilizing the Plan's
analytical data tools to calculate projected flow gaps by comparing existing stream flows to prior
years. April summarized that understanding our complex water system can be overwhelming and
technical When contemplating how to make water decisions those decisions need to come down
to the day that the water is needed and how much water is needed and how effective that action
will be before a project is even contemplated. Because a water project could destroy
relationships, have legal ramifications and cause enormous expenditures. What the Plan did find
is that the community highly values the water resource. The participating stakeholders recognize
the need and are ready to partake in difficult creative water management conversations to
improve this valuable resource.
Discussion
Michael Kinley asked why the Plan has based important data numbers on prior estimates. Seth
responded the flow data is based on Fish & Wildlife Service estimates that are part of the Senate
bill that authorizes the development of water projects. For purposes of this Plan project, the Fish
&Wildlife Service data is known and accepted data. Decision was made early in the process to
utilize available data and not conduct a massive new study. Michael expressed concern that such
a pivotal number in the report is part of a bureaucratic sales pitch to Congress. Gary contributed
that to conduct a new study would cost a fortune. The Plan's models illustrate how 4,000-acre
feet would affect each stretch of the river over time. The simulation modeling tools allow the
flow numbers to be any amount. Seth continued the Plan is using available tools (data) to make
commentary about the relative degree of in-stream flow gaps. Coming up with 4,000-acre feet of
water would be a herculean undertaking. Michael continued that by the Plan prominently
highlighting '4,000-acre feet' then that number in effect becomes the gospel leading to future
project rationalizations that are doomed to fail Gary clarified the Plan's intention is to illustrate
how much water is needed to effect change for any segment of the river. The Plan will be
amended to note the 4,000-acre feet number reflects an amount that has been used in the past.
Water is a critical component when Open Space contemplates the purchase of any conservation
easement or fee property. OST can now use these simulation tools when planning property
actions especially within the upper Roaring Fork valley.

Michael remarked the Plan mostly references irrigation efficiencies with little reference about the
results of domestic efficiencies. Both irrigation and domestic efficiencies potentially avoid dams
and create capacity resilience that can withstand droughts. April responded the City's water
source is from Castle and Maroon Creeks improving domestic /commercial efficiencies affect
those sources, but not the health of the upper Roaring Fork River, which flows through the City
and is above those tributaries. Michael felt the response did not address the overarching water
issue.
Graeme Means asked whether recent programs that allow ranchers to return / release water back
into a river could be a tool in the Roaring Fork River watershed. Seth responded these types of
innovative releasing tools were included in the stakeholder conversations. There are some on-
going concerns about exposing a water right to any source of quantification like the Colorado
Water Conservation Board (CWCB) leasing program. Any legal issue surrounding a water right
is a concern. Other non-CWCB lease back tools work best in areas that do not have complex
water rights issues. The upper Roaring Fork does have the potential for some innovative
opportunities, which continue to be discussed with the stakeholders. April contributed over the
past five years the City has participated in a non-diversion agreement on the Wheeler Ditch and
it is contributing in a small way to meet the minimal in-stream flow. This action also reduces
raw-water irrigation.
Wayne Ives asked whether a comparison could be made between the Crystal River Plan and the
URFR Plan. Seth responded the stakeholder dynamics are very different. Roaring Fork has more
consensus about river health and more legality concerns. Geography issues are similar with the
greatest river impacts below water diversion infrastructures,. The Crystal area is more about
stakeholder trust building on an individual basis.
Amy Barrow noted the Plan illustrates how challenging it is do anything with the water and
questioned how action projects will evolve from the Plan. Gary replied there are North Star
habitat improvement projects in the works and OST will be consulting with Seth. The projects
will not create additional water for the City, but it will improve the quality of habitat and overall
ecology through the river's North Star stretch. Seth contributed that it is best to think of projects
as incremental seed changes supporting long-term implementation goals.
Howie Mallory questioned whether the City's grey-water program would have any river impacts.
April responded the City's grey-water program's infrastructure is installed, but the City is still
dealing with permits from the State. It is odd that the grey-water is clean enough to return to the
river yet not clean enough to irrigate a golf course. The re-use line runs from the sanitary
treatment facility to irrigate Burlingame properties and the golf course. Currently these areas are
irrigated with raw water from Castle and Maroon Creeks once the system is functioning it will
reduce the diversion from these trbutaries. The critical river segments are upstream from these
tributaries and thus does not meet the acre-feet in-stream gap. The additional acre-feet of water
needs to be above the Salvation Ditch diversion. Howie questioned whether the grey-water could
be delivered further into the City. April responded it would be an infrastructure challenge but
could be the kind creative solution worth exploring. While it seems absurd to pump water
upstream to solve this problem, it may actually be part of a solution.

Graeme asked about the role of beavers. Seth replied there are possible beaver management
opportunities in areas like North Star and Brush Creek. Beaver activity has the potential to
increase the aquafer storage capacity. Beavers are a tricky approach; heavy beaver activity can
alter recreation activity.
See Board Action below.
Emma Open Space Agricultural Structure Update
Section 4.2.2 of the Emma Open Space Management Plan allows for the development of
agricultural structures with consent from the Conservation Easement holder Roaring Fork
Conservancy. Through Pitkin County's formal bid process, Two Roots Farm was awarded a ten-
year lease in early 2018. Staff worked with the lessee to determine potential facility locations.
OST conducted an online public survey with four options; Option A (location site), Option B
(location site), Option C (no structure) and Other which allowed participant to offer a location or
other thoughts. One hundred nine public responses were submitted with 89 for Option A, 6 for
Option B, 7 for Option C no structure (the majority of seven responses were averse to public
funding private enterprise), 3 for either A or B as long as location met the lessee needs, one
proposed locating near the cottonwood trees, 2 were against any structures on open space and
one proposed utilizing the Emma Townsite location. The Emma Caucus was provided a site visit
on March 29th and on April 30th the Caucus conducted a special meeting to discuss the options
and process. Emma Caucus did not vote, but submitted a summary of members that did
comment. Summary of the public survey results and the Emma Caucus comment are included in
this meeting's materials.' Staff is recommending the OSTB support a$10,000 budget
supplemental to contract an architect for structure designs and develop cost estimates for a range
structure design scenarios. Staff will research structure construction funding strategies including
County funded and leased back to lessee, privately funded, and/or a combination of fiinding
sources.
Public Comment
Tom Cardamone offered comments primarily as the Executive Director of the Watershed
Biodiversity Initiative (WBI) also as a member of the Emma Caucus who supports Emma OS
agricultural project. Eagle County has identified the general Emma area as a likely location for a
wildlife crossing. Tom referenced the success of the Banff wildlife crossings could be applied in
this area. There is potential to connect Maroon Bell Snowmass area through Light Hill to Lake
Christine wildlife areas and beyond to Red Table wilderness area. Keeping this potential in mind,
Tom commented to keep the Emma Open Space as open as feasible with structures as far west as
possible. Noting hoop houses are moveable structures. The lessee's current 8 foot fencing creates
a barrier that is problematical, as would any other agricultural production protective fencing.
Gary added the Emma OS management plan speaks to discussing a wildlife crossing possibility
with Eagle County. Colorado Parks and Wildlife (CPW)will be major contributor in these
discussions. Gary added the biggest difficulty is the Emma /Basalt area is heavily developed.
The Willits development area was a wildlife crossing area and the wildlife still try to cross there.
Graeme added his observations of Croatia's coastal highway where he encountered several very

wide landscaped wildlife crossings. Michael questioned Tom whether the agricultural fence
location was more critical factor than the structure location. Tom responded that both are of
concern, but the wildlife conflict increases if operations move further east. Best to keep potential
barriers to the west.
Emma resident Happy Day Ranch owner, Ginny Parker commented she faces a dilemma. She
wants the Emma lessees to be successful but sees OST actions that supply agricultural facilities
on public land is in direct competition with the area's private property owners who are trying to
make a go of their agricultural businesses. It seems to her that the only way for some private
owners to succeed is to sell their land. Ginny would like to see OST funds spent on maintaining
assets and not funding operations in competition with the areas private enterprises. She also
added from her ranching experience not all agricultural endeavors succeed and then what
happens when all this money is spent building facilities and ultimately the agricultural endeavor
proves unsustainable. In sixty-five years, her land has not been able to turn a profit. Everyone in
her family have other jobs to keep the ranch functioning. Dale Will reminded the board of
Ginny's generous donation of a public trail easement across her property known as Nancy's Path
that connects to adjacent public lands.
Board Comments
Wayne Ives questioned whether the Emma agricultural structure could be a multi-user facility.
Would other OST properties be a better location for multi-users processing? Wayne remarked
that he foresees the agricultural program will continue to generate discussions about the need for
agricultural facilities. Gary responded fixture management plan processes need to view the
agricultural areas holistically and to pose the structure questions in that process whether for a
new property or updating a property with agricultural leases and no facility structure. Amy
Barrow commented that shared facilities would be more efficient than having twenty-seven
barns. Gary added OST would supply to the board a summary of discussions conducted with
local small growers about their facility needs when the board reviews the final Emma OS
structure designs.
Wayne asked for a breakdown of infrastructure costs that Two Roots has incurred (fencing,
irrigation improvements etc.) This would illustrate to the public that OST is not funding the
lessee's entire infrastructure needs.
Graeme expressed his thoughts about the Emma Caucus' three areas of concerns; 1)why build
on open space land, 2) why is OST fund subsidizing, 3) why is OST competing with private
interests. Agriculture is part of OST's mission, which includes supporting local food production.
Sustainable agriculture requires facilities. Subsidizing is a difficult question. Large corporate
agricultural farms receive big federal subsidies while small producer receive none and must
comply with same safety and health standards regulations as the large producers. Competing
with private interests is a concern, but OST's agricultural leases are available for all to apply. By
OST encouraging sustainable agriculture, it is helping to create a market for local produce that
did not exist five to ten years ago when restaurants were not interested in locally raise produce.
OST's support of local food production benefits all local producers. Some public education
outreach about why OST is supporting local food production may be in order.
6/07/2018 OSTB Regular Minutes

Amy Barrow agreed with Graeme's comments. OST's agricultural leases are visibly producing.
She agreed that a concerted public information effort is in order. Including what OST is and is
not providing for lessees. OST needs to be judicious on how to expend OST funds. The
agricultural lessees are working the land for mutual public benefit.
Michael questioned who would own the Emma OS structure. Paul replied Pitkin County.
Michael questioned how the structure's aesthetics would be determined. Michael noted when
considering the economics of farming that OST's agricultural land ownership removes the
speculative land value market from the economics of firming. Gary offered to report back on
how the City of Boulder, Boulder County and Larimer County balance the economics of their
agricultural programs with private farms.
Graeme responded about the structure's architectural aesthetic considerations. The structure will
be next to the hoop house. The design will need to be in scale and capture new functional ways
of firming. Using functional modem materials.
Dale Will added to the comments about the economics of agriculture. The valley's speculative
land market is squeezing out agricultural lands. Over many years, the OST program has spent
millions of dollars on conservation easements that directly subsidize the landowner/rancher to
continue agricultural activities yet this kind of subsidy is not questioned.
Michael commented that the housing program was meant to keep housing affordable. DST's
overarching program purpose is not exactly meant to make farming affordable. Is there value in
a County policy that supports affordable agriculture regardless whether it is on easement or fee
owned land? Gary responded that preservation of agriculture is a huge piece of OST's charter.
And that includes all types of agriculture. The amount of OST funds spent on conservation
easements makes a strong supportive statement. Conservation easements have provided
landowners the wherewithal to continue agricultural endeavors on the land.
Gary added the Emma structure aesthetics is an iiiiportant board decision. The structure could be
cheaply constructed, but is that what the board wants? Staff will be presenting design options.
Ultimately, any structure is removable.
Howie Mallory supports Graeme's responses about the Emma Caucuses concerns. Howie also
agreed that purchased conservation easements are huge subsidies that keep landowners in
agricultural business and have raised very little controversy. Demonstrating that the public
supports OST's agricultural mission statement. Not every OST property can accommodate
agriculture and or local food production. One of the board's challenges is to review types of
opportunities on a case-by-case basis. Howie agrees additional public outreach about OST's
agricultural program is needed. He supports staff's recommendation while being mindful of a
potential wildlife bridge concept as presented by Tom Cardamone.
Graeme noted board consensus to move the Emma structure project forward. He suggested
public outreach addressing OST's objectives to protect agriculture. Dale proposed a policy
development similar to the creation of the Biodiversity Policy. Paul added that the existing
6/07/2018 OSTB Regular Minutes

Agricultural Lease Policy and Procedure can be expanded upon. Gary responded that staff will
bring options on how to accomplish this to the next meeting.
Michael suggested today's meeting minutes be forwarded to Ginny Parker and Cathy Markle.
See Board Action below.
Suzanne Wolff entered the meeting at 11:00 a.m.
Paragon Enterprises Referral
Dale provided location and historical context. Ted Koutsoubos and his partners own three lots
situated between Brush Creek Road, Brush Creek Trail and Sky Mountain Park. The Brush
Creek Trail easement is along one of the property lines and was a dedication resulting from prior
approvals. Paragon Enterprises building rights are not in question. Staff is recommending that
the previously negotiated environmental protections built into prior land approvals be reiterated
in the board's referral Including that human activity above Upper Wiese Ditch area be restricted
to mirror Sky Mountain Park's closure dates from December 1 to May 15. And any dog on the
property must be leashed or kenneled. A well fenced area adjacent to a house is an acceptable
kennel area.
Discussion
Howie asked whether invisible fencing was allowable. Suzanne Wolff stated that invisible
fencing does not meet Pitkin County's kenneling requirement.
See Board Action below.
Torn Cardamone left the meeting at 11:40 a.m.
Red Mountain HOA Rockfall Mitigation
The Red Mountain HOA property dedication closed last week. Dale reported the property
inspection revealed additional rockfall mitigation beyond what was originally anticipated.
Richard Neiley added the rockfall mitigation work is estimated between $270,000 to $295,000.
The HOA has put $156,000 into escrow toward the mitigation work. Contractors and County
Engineer are reviewing the property to come up with a firmer estimate. Staff is recommending a
budget supplemental up to $150,000 subject to a final mitigation contract.
Discussion
Wayne questioned whether it is necessary to mitigate all the rockfall hazards. Richard responded
that of the identified five rockfall hazards, one is very close to the property border. If that
rockfall hazard is identified as outside the property then one of the Red Mountain property
owners will cover that mitigation.
Howie questioned what will trigger the release of the Red Mountain HOA mitigation payment.
Richard replied the mitigation contractor will be Rock Solid and when the work is completed the
funds will be released upon the mutual consent the HOA and County. HOA's escrowed funds are
held by Land Title.
See Board Action below.

Upper Roaring Fork River Management Plan 12017
EXECUTIVE SUMMARY
In the early 2000s, several studies were completed that showed riparian and in-
stream habitat degradation in the stretch of the Roaring Fork that flows through
Aspen. In 2012, the Colorado Water Quality Control Division placed that stretch on
Colorado's list of Impaired Waters. Several factors can impact the health of aquatic
and riparian plants and animals such as water quality and near-stream land use
activities. However, fluvial ecologists generally treat streamflow as the "master
variable" exerting the largest influence on river ecosystem conditions. Therefore, the
City of Aspen and Pitkin County began the process of an Upper Roaring Fork River
Management Plan, focusing on identifying impacts caused by modified patterns of
streamflow and developing goals and strategies for managing land and water to
improve or protect river health in the upper Roaring Fork watershed. The City and
the County worked with a team of consultants and local stakeholders to prioritize
ecological considerations and develop tools to assist in predicting effectiveness of
various management alternatives.
Streamflows in the upper Roaring Fork watershed are heavily modified due to
transmountain diversions and in-basin agricultural and municipal diversions.
Transmountain diversions reduce the average annual water yield in the Roaring Fork
River above Mill Street by approximately 40%. An additional 10% reduction in average
annual yield is due to agricultural and municipal uses near the City of Aspen. Of this
10%, approximately one quarter is used by the City of Aspen for water amenities on
the pedestrian mall, irrigation of public parks, and support of the stormwater
treatment wetlands at John Denver Park. Reductions in streamflow during late
summer and fall low-flow periods can negatively impact habitat quality and
availability for fish and insects. Reductions in flow also reduce a streams ability to
assimilate solar radiation and chemical compounds that find their way to the river,
potentially, degrading water quality conditions. Alterations of peak flows limit a
stream's ability to replenish important spawning habitat for native and sport fish, to
maintain the physical shape and dynamics of the stream channel, and to replenish
riparian vegetation and alluvial aquifers with water.

The importance of ecological streamflow protections was recognized during the
development of the Fry-Ark project and flow targets were incorporated into that
project's Operating Principles. Additionally, minimum in-stream flows necessary to
meet environmental needs on many streams reaches in the upper Roaring Fork
watershed were quantified and the Colorado Water Conservation Board (CWCB),
which obtained water rights to protect those needs in the 1970s. More recently, local
conservation organizations commissioned special studies to investigate the flood

trans-mountain diversions.
Management recommendations for peak flows are regularly met on the Roaring
Fork River. Recommended low flow thresholds, however, are not met on some
sections of river during average and dry-year conditions. Minimum flow shortages
are particularly prevalent on Hunter Creek, the Roaring Fork River between Lost Man
Creek and Lincoln Creek, and on the Roaring Fork River through Aspen. Some
shortages are due to the lack of native/natural water supply, indicating that in some
locations and at some times of the year, the existing recommendations for
minimum streamflows may need refinement or are not necessarily ideal targets for
management activities. The largest shortages occur in late summer months and on
the mainstem Roaring Fork typically below Stillwater Lane, where water diversions
that support agriculture, ponds, private landscaping, and parks deplete late-summer
streamflows. In general, shortages are more acute during dry conditions than during
average or wet conditions.
Developing viable strategies for addressing shortages to environmental water needs
requires an understanding of the full suite of water uses in the Upper Roaring Fork
watershed. While some shortages are natural and unavoidable, most of the
shortages result from surface water diversions. It is important to recognize that the
uses of water that impact river health are often vital to the functioning of local
economies and ways of life. Therefore, the viability of efforts to manage water for the
protection and benefit of the environment depend on a broad understanding of
how water moves through the upper Roaring Fork watershed, the values associated
with various water use types, and the difficult trade-offs associated with any change
in existing water management.
Stakeholders and members of the public participated in an exploration of
geographic priorities, community values regarding the various ecosystem attributes,
and the types of water management actions that the City of Aspen and Pitkin
County may employ to improve river health (e.g. water transactions, water storage,
channel reconfiguration, infrastructure upgrades, etc.). Geographic priorities
identified by the community aligned with environmental flow need shortages.
Though the consulting team had anticipated that there would be a clear preference
for managing to improve or protect ecological conditions on the section of the
Roaring Fork that flows through Aspen (and there was), Hunter Creek and the upper
iv
Exhibit A: 6/07/2018 OSTB Regular Session Minutes
Roaring Fork were also called out as important areas for consideration, as portions of
each are frequently dried up by water diversions.
In ranking exercises and small-group discussions, ecological integrity received the
highest allocation of points as a priority water use- both because of its singular
importance for community members, and because of its function in supporting
recreation and other uses. Domestic water supply was a close second in priority
water use. The high allocation of preference points to managing for ecological
integrity and domestic water supply—and the significant potential that
management of one attribute will come at the expense of the other—confirms the
critical importance of understanding the impacts of domestic water supply
development on the ecological health of streams and rivers. The inverse is equally
true. Responses indicated the local community is resistant to managing for river
health at the expense of domestic supply reliability. The potential for conflicting
management goals is high, which speaks to the need for continued engagement
with stakeholders and members of the local community when conducting these
types of planning efforts.
Communications with stakeholders elucidated important community preferences
for general categories of water management actions. The management actions
considered by stakeholders ranged from water system efficiency upgrades to
reservoir construction (Table 3).These actions were primarily relevant to managing
low flows, since modifications of this aspect of streamflow are widespread in the
upper Roaring Fork watershed. Sensitivity around ongoing legal cases—one
involving Pitkin County and administration of transmountain water rights, the other
regarding water supply development planning by the City of Aspen—prevented
evaluation of any single specific action in detail. Nonetheless,this project did include
a high-level effort to vet previously proposed management actions with
stakeholders and community members. In addition to clarifying community values
and preferences for water use, stakeholders weighed the potential ecological
benefits of several water management opportunities against the financial, legal,
administrative, and political constraints (and other tradeoffs) each posed.This
process helped identify a number of management activities that may be used to
effect positive change in measures of river health on the Roaring Fork River.
Management opportunities that warrant further investigation include:
• Optimization of the Twin Lakes Exchange
• Joint Operation of City of Aspen Municipal Supply and Salvation Ditch
• Dry-Year Municipal Raw Water Supply Reductions
• Maroon Creek Municipal Water Right, CWCB lease or dedication
• Dry-Year Water Leasing with the Salvation Ditch Company
• Hunter Creek Cutthroat Trout Management
• Hallam Lake Cutthroat Trout Introduction
• North Star Preserve Wetland Drain Removal
Moving forward, the City and the County should capitalize on the trust and
relationship-building that occurred during this project among diverse stakeholders.
Water supplies in the upper Roaring Fork watershed are finite, support a diversity of
V
Exhibit A: 6/07/2018 OSTB Regular Session Minutes
uses, and are fully allocated at certain times of year. Management actions that
support or improve one use opportunity for one type of water need may reduce use
opportunities for another. For example, improving late summer flows in the Roaring
Fork River through Aspen might be achieved through a reallocation of City of Aspen-
owned water from public parks and fountains to the river. Alternatively, low flow
conditions might be improved through leasing programs or contractual
relationships that allow for temporary reallocation of water from irrigated agriculture
to the river. Both of these actions would likely benefit aquatic plants and animals but
may do so at the expense of aesthetic enjoyment of water features in the City of
Aspen or at the expense of water amenities, green viewscapes, and agricultural
production in McClain Flats. In order for either option to proceed beyond conceptual
planning levels, there will need to be widespread buy-in from key water users and
the local community.
In the course of this study, the entities that participated had the opportunity to
discuss their goals for the river, concerns about current conditions, and interests in
future river management. In discussing principles for building trust and mutual
understanding, stakeholders underscored the importance of open, interest-based
