The Library of Congress has dozens of photos taken by photographer Russell Lee during the depot's construction in the early 1940s. PHOTOS COURESY OF THE LIBRARY OF CONGRESS At the height of construction, there were more than 7,000 men and woman working in various capacities at the Umatilla Army Depot. Construction workers build one of the igloos at the Umatilla Army Depot. In all, there were a total of 1,001 igloos built at the depot base. The U.S. Army Corps of Engineers began planning the construction of the Umatilla Ordnance Depot, as it was first known, in the summer of 1940. Workers pour concrete into one of the igloos being built at the depot. Work on the depot begin in 1940 and wrapped up one year later. Hermiston was chosen as the depot site because of its rail connections and its interior location, which would make it a more difficult target for enemy aircraft.
