Cheesman Reservoir History

Cheesman 2008

Cheesman Dam, which was named for Walter Scott Cheesman, was the world’s tallest at 221 feet when it was completed in 1905. Cheesman was the first reservoir of Denver’s mountain storage facilities – a small, but visionary, beginning that helped expand Denver Water’s system.

In 1973, the dam was designated a National Historic Civil Engineering Landmark. It remains, after more than 100 years, the workhorse of the storage system and jewel among the system's dams, a monument to thoughtful planning and wise water use.
