Building/structure dates: 1923 initial construction
Significance: Completed ca. 1923, it is locally significant to Boulder County as an intact example of an early 20th century, and relatively uncommon, arch concrete dam. The dam documents an important engineering achievement in that its completion represented an early successful solution to the logistical difficulty of high altitude dam construction in the region. It is a concrete arch structure 146.7' long, abutting granite rock on the north side and a 49.5' high concretes abutment on the south side. The structural height of the dam is approximately 55 '. The dam is a mean elevation of 10,978 feet.
