Halligan Reservoir is an existing reservoir on the North Fork of the Poudre River, 25 miles northwest of Fort Collins.
If approved, the Halligan Water Supply Project will enlarge Halligan Reservoir by approximately 8,100 acre-feet to help provide additional protection for Fort Collins Utilities' water customers from future service interruptions during emergencies.
The project will help:
- Provide a storage reserve for emergency water supply disruptions
- Increase drought security
- Improve water system reliability and flexibility
- Meet future water demands of the Fort Collins Utilities' water service area
Currently, the U.S. Army Corps of Engineers (Corps) is working on a draft Environmental Impact Statement (EIS) before making a final permitting decision on if Halligan Reservoir can be expanded.
We anticipate the release of the draft Environmental Impact Statement (EIS) in 2019.
The City of Fort Collins is currently developing mitigation and enhancement plans.
