23-001 The Walla Walla District to celebrate its 75th anniversary in November

Posted on January 4, 2023

The U.S. Army Corps of Engineers, Walla Walla District, will be celebrating its 75th anniversary on Nov. 1, 2023.

The district was established on Nov. 1, 1948, just a few years after the completion of the Mill Creek Project.

The land that would become the Walla Walla District was originally part of the USACE Portland District. In the 1940s, several large construction projects were initiated, projects that would go on to become McNary Lock and Dam, Lucky Peak Dam and the four Lower Snake River Dams. All of these activities, plus the future work that was envisioned, prompted a survey in 1947 of several towns, including Pendleton, Tri-Cities, Spokane, Boise, and Walla Walla for the best location of a possible District office.

The City of Walla Walla was ultimately chosen, and, in Nov. 1, 1948, the Walla Walla District was born!
