Yuma Quartermaster Depot State Historic Park is the site of an old Army supply depot that operated between 1864 and 1883. The purpose of the depot was to store six months' worth of supplies for all the forts in Arizona Territory and several forts outside of the territory. After abandonment by the military, various federal government agencies moved into the buildings. These agencies included the Bureau of Reclamation, the U.S. Customs Service, and the U.S. Weather Service. Five of the original depot buildings remain on the park grounds, and four of these buildings contain exhibits. Exhibits cover both the military history of the site and the history of the Bureau of Reclamation's construction of major irrigation works in the Yuma area during the early 1900s.
