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 meet the demand of future Fort Collins Utilities' water customers and provide increased reliability for existing customers to help protect against service interruptions related to prolonged drought and 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 EIS in 2019.
The City of Fort Collins is currently developing mitigation and enhancement plans.
Fort Collins Utilities has updated the cost estimate for the Halligan Water Supply Project.
