RE: Update on Regional Water Supply Projects and Collaboration Opportunities
Bottom Line
City Council discussed the need for collaborative solutions to regional water supply issues at an
October 18, 2016 City Council Meeting. The City (through Fort Collins Utilities) is pursuing the
Halligan Water Supply Project (“Halligan Project”) to meet the future water needs of the Fort
Collins Utilities water service area. Water security is also a broader regional issue that will require
collaborative solutions by multiple water providers. Numerous water supply projects have been
proposed to address a regional water supply gap, which for the Northern Front Range is expected to
exceed 150,000 acre-feet per year by the year 2050. These proposed projects, even if fully adopted,
will not fully address the future water gap projected for the region. This memorandum provides an
update on several such water supply projects relevant to the City both in terms of water supply and
environmental impacts, and suggests various opportunities for collaboration. An overview table of
key projects is provided at the end of this memorandum
Regional Water Supply Needs
As part of the 2015 Colorado State Water Plan, the Colorado Water Conservation Board (“CWCB”)
asked member roundtables1 to assess their future water supplies and demands, and to calculate the
water supply gap for the year 2050. The South Platte Basin Roundtable projects by the year 2050 the
Northern Front Range (Larimer, Weld, and Boulder Counties) expects to face a water gap of 152,000
acre-feet per year2. Larimer County alone faces a gap of over 50,000 acre-feet per year. The South
Platte Basin Roundtable also identified various water supply projects and processes to fill this gap,
including projects such as the Halligan Project and the Northern Integrated Supply Project (“NISP”)

major river basins in Colorado.

and processes such as conservation and agricultural water sharing. Even with these projects and
processes implemented, the Northern Front Range still faces a sizeable water supply gap. Failure to
implement these projects and processes will likely promote additional buy-and-dry conversion of
agricultural water and may curtain economic development in the region. These findings illustrate
the urgency of water supply planning and of pursuing collaborative solutions to water development.
Water Supply Projects
Many water supply projects are proposed along the Northern Front Range, some of which have the
potential to benefit and/or negatively impact the City. An overview of key projects relevant to Fort
Collins is provided at the end of this memorandum. Attached to this memorandum are maps of the
various projects.
Of the projects listed, NISP has perhaps received the most scrutiny from the City. In 2008 and again
in 2015, the City developed a comprehensive set of comments on the project, which were submitted
to the U.S. Army Corps of Engineers (“Corps”), the lead agency in NISP’s federal permitting
process. A majority of the City’s concerns focused on the impacts NISP would have on flows in the
Poudre River, particularly during low flow and peak flow periods. Since 2015, there have been three
developments related to NISP that merit further discussion:
1. Northern Water proposed a new conveyance refinement alternative that could enhance low
flows in the Poudre River along a 12 mile reach from the mouth of the Poudre canyon to
downstream of Lemay Avenue. Staff views this new NISP alternative as an improvement
over previous proposals. In order to preserve flows in the river along a one mile longer reach,
NISP has proposed relocation of the City’s Mulberry Water Reclamation Facilities discharge
point.
2. Pursuant to direction at the June 14, 2016 City Council work session, staff has met with
Northern Water several times to discuss NISP and its impacts on Fort Collins. These
discussions have been helpful in developing further information related to NISP (such as key
issues like peak flows) and its impacts on Fort Collins, as well as Northern Water’s position
on various NISP-related matters. Since the June 14, 2016 City Council work session,
Northern Water has continued to make progress towards acquiring the necessary approvals
for NISP.
3. Glade Reservoir, a component of NISP, is a Corps alternative to the enlargement of Halligan
Reservoir, and is being evaluated as part of the Halligan Project. The alternative proposes to
enlarge Glade Reservoir, if constructed, by less than 4% from 170,000 acre-feet as proposed
by NISP to 176,100 acre-feet. Early indications are that the Glade Reservoir alternative is
feasible and is comparable in cost to the Halligan Project. However, the Glade alternative
will require large pumping and energy inputs, and will generate more greenhouse gas
emissions than the Halligan Project.
Opportunities for Collaboration
NISP provides an opportunity for the City to seek collaborative solutions in addressing the regional
water supply gap. It is staff’s opinion that many of the City’s concerns with the project could be
addressed through a robust, comprehensive, and permanent mitigation plan. Northern Water has

proposed at least one mitigation strategy, the conveyance refinement alternative, that may improve
conditions on the river in certain respects. Other mitigation actions such as the provision of peak
flows are presently under evaluation. NISP streamflow mitigation could be folded into other
regional efforts to protect and improve streamflows on the Poudre River, such as the instream flow
augmentation plan being developed by the Colorado Water Institute’s Poudre Runs Through It
group, a regional effort that includes Fort Collins (City Council approved an intergovernmental
agreement for this project last year). The City’s collaborative participation in NISP’s mitigation
process has the potential to support water development that also protects City interests and river
health. City Council action is needed to participate in the NISP mitigation process.
Other opportunities for collaboration exist within the City’s own water supply planning efforts. The
City is currently collaborating with both the East Larimer County Water District (ELCO) and the
Fort Collins-Loveland Water District (FCLWD) on regional water issues through a Regional Water
Collaboration Steering Committee. The Committee identified at least 10 key regional water issues
that are of shared interest. In addition, the Committee committed to focusing in the coming months
on water conservation efforts, alignment of shortage response plans, and joint water supply and
drought planning efforts. This renewed interest in collaboration has the potential to benefit the
region relative to meeting its water supply needs.
The Halligan Project was originally a regional water project between the City, the Tri-Districts, and
the North Poudre Irrigation Company; however, other regional partners withdrew citing the length
and cost of the federal permitting process. Regardless, there are future opportunities to collaborate
regionally on other water storage alternatives. City staff has evaluated numerous alternatives to the
Halligan Project over the past several years. One alternative presently under evaluation is the use of
deep bedrock aquifer storage and recovery (ASR). The City has funded a conceptual study of ASR
by consultants and researchers at Colorado State University, with matching funds from the CWCB.
This study has yet to be finalized, but has not yet indicated any fatal flaws. If proven feasible, ASR
could be developed collaboratively with other regional water providers, such as the Tri-Districts.
There are also potential opportunities for new water supplies and projects that will be looked at by
the City, ELCO, and FCLWD in the current regional collaboration discussions. Staff will update
City Council as those discussions continue.

Reservoir is a potentially
feasible and cost‐effect
alternative to the Halligan
Project. May provide base
flow benefits to the Poudre
River.
Numerous including:
streamflow reductions,
ecological damage to
the Poudre River, loss of
stormwater conveyance,
construction
disturbances, and water
quality degradation.
Windy Gap
Firming Project
Chimney Hollow
Reservoir at 90,000
acre‐feet; additional
transbasin Colorado
River diversions
Northern Water on
behalf of 13 Windy
Gap water users,
including the Platte
River Power
Authority (PRPA).
Operational in
2022. Next
milestone:
issuance of a
404(b) permit in
early 2017.
PRPA provides power to
Fort Collins. Will increase
reliability of the Reuse Plan
which provides water to
Fort Collins Utilities via
water trades with PRPA.
Most impacts are to
West Slope resources.
Seaman Water
Supply Project
Enlarge Milton Seaman
Reservoir by approx.
48,000 acre‐feet
City of Greeley
Operational date
unknown. Next
milestone:
publication of a
draft EIS in 2018.
Joint operations between
Halligan and Seaman
Reservoirs could provide
flow benefits to the North
Fork and aid in mitigation
of the Halligan Project.
Too preliminary to
assess, but expected to
have flow, water quality,
and ecological impacts.
Thornton
Northern
Water Project
Construct a pipeline to
transport previously
changed water rights
from the Poudre River
to Thornton
City of Thornton
Operational in
2025. Next
milestone: land
use permitting.
None identified.
Few direct impacts:
construction will be
outside the City; no
expected to change
Poudre River flows.
