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
The U.S. Army Corps of Engineers (Corps) released a draft Environmental Impact Statement (EIS) in November 2019. The Corps will develop a final EIS before making a permitting decision on if Halligan Reservoir can be expanded.
We received approximately 60 public comment letters or statements. Together, with the U.S. Army Corps of Engineers, we’re evaluating each comment to determine next steps for the final EIS and Conceptual Mitigation Plan.
We kicked off the process for the state Fish and Wildlife Mitigation Plan with Colorado Parks and Wildlife (CPW) in April.
