HALLIGAN WATER
SUPPLY PROJECTUPDATE
August 2020
BACKGROUND
The Halligan Water Supply Project would
enlarge Halligan Reservoir, an existing
reservoir on the North Fork of the Poudre
River, to meet the demand of future Fort
Collins Utilities’ water customers and
provide increased reliability for existing
customers in the event of emergencies,
drought and climate- change uncertainties.
The project would expand the reservoir
by about 8,100 acre-feet by increasing the
height of the existing 70-foot dam by 25
feet. For context, an average single-family
home uses almost a third of an acre-foot of
water each year (about 108,000 gallons).
The project is anticipated to be completed
in 2026.
The project reached a milestone in
November 2019 after many years of hard
work, when the draft EIS was released.
Permits are required from the U.S. Army
Corps of Engineers (Corps) and other
federal, state and county agencies to
enlarge Halligan Reservoir. Staff continue
to support preparation of a final EIS by
the Corps. Additionally, staff are working
toward other permitting processes,
including the Fish and Wildlife Mitigation
Plan and the 401 Water
Quality Certification.
PROGRESS UPDATE
Permitting and Mitigation
• The Corps is addressing comments on the draft EIS and working
toward preparation of the final EIS, which is anticipated in 2021. For
a comment summary, visit fcgov.com/halligan-comments.
• Staff are working closely with Colorado Parks & Wildlife to develop
concepts for the Fish & Wildlife Mitigation Plan. This process kicked
off May 1.
• Work toward the 401 Water Quality Certification continues,
including additional water quality sampling this year.
Property Acquisition and Easements
• Staff continue to work with several landowners to develop
easement agreements for permitting and design access.
Preliminary Design
• Preliminary design activities are underway.
Public Engagement & Communication
• See below for project-specific communications and engagement
since January.
The Halligan Dam typically spills every spring with
excess runoff from the snowpack.

ANTICIPATED COSTS
Project costs were updated in 2019 pending the
release of the draft EIS and with information
learned over the previous two years. The estimate
is presented as a range due to the long-term
nature of the project, the conceptual nature of
the current design and the uncertainty associated
with a complex water supply project. As noted in
previous quarterly updates, costs are anticipated
to change and likely grow as the scope is refined
and permitting requirements and design elements
are better understood.
Costs will be updated again in 2021 after
preliminary design is complete and more is
known about the project design, permitting and
mitigation elements. Costs will continue to be
updated as new information is obtained. Updated
cost estimates and other decision factors will be
evaluated at project milestones to verify that the
Halligan Project remains the most cost-effective
water supply solution for Utilities’ customers.
Currently, the Halligan Project is anticipated to
provide firm yield at about $15,000 per acre-foot
and is the most cost-effective project to meet
the City’s water supply needs. For comparison,
the market rate for firm yield from the Colorado-
Big Thompson (CBT) Project is approximately
$60,000. Also, the Northern Integrated Supply
Project (NISP) and Windy Gap Firming Project
unit costs are currently $30,000 and $20,000
per acre-foot, respectively.
