Granby Dam, Embankment dam in Grand County, Colorado, US.
The Granby Dam rises 298 feet high and extends 880 feet across the Colorado River, forming Lake Granby with a storage capacity of 539,760 acre-feet.
Construction of the Granby Dam began in 1941 as part of the Colorado-Big Thompson Project and reached completion in 1950 under the U.S. Bureau of Reclamation supervision.
The dam functions as a central element in Colorado's water management system, supporting agriculture and municipal needs for cities including Boulder, Fort Collins, and Greeley.
Water from Lake Granby moves through the Granby Pumping Plant to Shadow Mountain Lake, then travels through the Alva B. Adams Tunnel to serve northeastern Colorado.
The dam incorporates a system where water from Willow Creek is pumped up 175 feet into Lake Granby, demonstrating advanced engineering for water resource management.
