History

Umitilla - city hall - July 2013
City hall in Umatilla, Oregon

The first Umatilla post office was established in September 1851 at the Umatilla Indian Agency about 5 miles (8 km) east of Pendleton, and discontinued in January 1852. This was before Timothy K. Davenport surveyed for a town site at the mouth of the Umatilla River in 1862. The site was first known as Umatilla Landing, then Umatilla City, then Columbia, then Umatilla City once again over the next year or so. Its post office was established in 1863 with Z. F. Moody as postmaster.

Umatilla's earliest importance was as a trade and distribution center on the Columbia River, during the gold rush of the 1860s and 1870s in eastern Oregon. It remained a major commercial center until the 1880s when it withered before the Oregon Railway and Navigation Company.

The Umatilla Chemical Depot opened in 1941, to prepare for World War II. The depot's mission was to store and maintain a variety of military items, from blankets to ammunition. The depot took on its chemical weapons storage mission in 1962. From 1990 to 1994 the facility reorganized in preparation for eventual closure, shipping all conventional ammunition and supplies to other installations. On October 25, 2011, the last barrel of HD mustard agent was destroyed and there is no longer a risk of chemical accident in Oregon and Washington.
