It was created by the erection of Granby Dam, completed in 1950, as part of the Bureau of Reclamation's Colorado-Big Thompson Project. Water from Lake Granby is pumped via the Farr Pump plant though a pipeline that empties into a canal connected to Shadow Mountain Reservoir. The Bureau of Reclamation owns Farr Pump plant while Northern Water operates it. On its own, Lake Granby contains approximately 40 miles (64 km) of shoreline.[1] The lake is popular with anglers and is continually stocked with rainbow trout and kokanee salmon.[3]
The Lake is also home to the Lake Granby Yacht Club. At 8,280 feet (2,520 m), LGYC is one of the highest-elevation yacht clubs in the world,[4] slightly beaten by Grand Lake Yacht Club at 8,369 feet (2,551 m) on nearby Grand Lake.
