Umatilla Army Depot

Base Background

Location Umatilla, Oregon, 97882, United States
Years of Operation 1941-2012

The military finished construction on the Umatilla Army Depot in 1941. Soon after the opening, about twenty thousand bombs arrived at the facility for storage. The depot continued to store ammunition and supplies through the 20th century. During this time, seven million pounds of chemical weapons were stored at the site. The depot officially closed in 2012.
