In 1909, Halligan Reservoir was constructed on the North Fork of the Poudre River. For more than 100 years, this historic dam has provided around 6,400 acre-feet of water storage to the shareholders of North Poudre Irrigation Company (NPIC).

Fort Collins Utilities and NPIC completed a study to enlarge Halligan Reservoir to increase water supply reliability, especially during drought years. 

Utilities updated the 1989 feasibility study to address current environmental issues and project costs. The 2002 feasibility study outlined four dam types at three alternative locations, each storing volumes of 15,000, 25,000 and 40,000 acre-feet.

The Water Supply and Demand Management Policy was approved, which confirmed a need for storage.

NPIC retains existing storage capacity.

This includes surrounding water districts and NPIC.

Utilities began federal permitting process with project partners and agreed to jointly permit Halligan and Milton Seaman reservoir expansions with Greeley

All of our project partners, including water districts, withdrew from the process, due to the lengthy permitting process and the rising costs associated with permitting-related delays.
