Description	The Halligan Reservoir Expansion Project involves expanding the existing reservoir near Fort Collins, Colorado, by building a new dam and spillway 200 feet downstream of the current dam. The expansion will more than double the reservoir's capacity from 6,400-acre feet to 14,600-acre feet, providing increased water storage for Fort Collins Utilities and improving the downstream ecosystem. The design is being refined through physical modeling at Colorado State University's hydraulics lab, complementing computer modeling to optimize the dam, spillway, and stilling basin design. The project also includes replacing the aging dam and ensuring year-round flow of the North Fork of the Poudre River downstream.
