Schofield Barracks Military Reservation, Ku Tree Reservoir, Spillway, Kalakoa Stream, East Range, Wahiawa, Honolulu County, HI

Significance: The spillway is significant as an element of the Ku Tree Reservoir and as a good example of a spillway constructed for an earth-fill dam in Hawaii in the 1920s. The spillway embodies the distinctive characteristics of its type, period, and method of construction, while possessing high integrity. While the individual elements of the design are typical, such as the utilitarian pedestrian bridge, overall it is a notable example of this type of engineering structure in Hawaii. Because of Ku Tree Reservoir's capacity and the size of its watershed, its spillway, with a length of 460' and 68 percent slope, is one of the more impressive spillways in the state.
