Cheesman Reservoir

A breathtaking engineering landmark

Named for Denver water pioneer Walter S. Cheesman, the dam was once the world’s tallest at 221 feet above the streambed when completed in 1905. The Denver Water Board purchased the reservoir and related facilities in 1918. Cheesman was the first reservoir of Denver's mountain storage facilities and has been designated a National Historic Civil Engineering Landmark.
