Lake History

About Lake Granby
1949

In the Beginning

The first water storage at Lake Granby began in September 1949. The dam was completed in 1950 by Granby Dam and continues to operate today as part of the Colorado-Big Thompson Project – a project aimed to collect around 200,000 acre-feet of water each year.

The Colorado-Big Thompson Project is the largest trans-mountain water diversion project in Colorado and consists of 12 reservoirs (Lake Granby being the largest), 35 tunnels, 95 miles of canals, and 700 miles of transmission lines.
