The U.S. Army Corps of Engineers and Waterways in the Pacific Southwest

Throughout the entire 20th century, the USACE developed a complex infrastructure of dams, man-made rivers, levees, and reservoirs throughout our region.  Without these massive construction projects, many of the residential and commercial developments in the area would not have been possible.  The Army Corps changed the landscape of Southern California, Arizona, and Clark County in order to make the region a safe place to live—and the images of the construction of these fixtures illustrates the ways in which the area has developed in the past century.

Throughout the month of July, the National Archives at Riverside is taking the opportunity to share images, documents, and records that celebrate our local history.  As the archives that holds permanent federal records for Southern California, Arizona, and Clark County, we have records from the states’ Territorial eras, records relating to the development of the region as a center of commerce and culture, and records depicting the natural beauty and built environments of our unique home.  This July, join us in celebrating our heritage as Americans and our heritage as stewards of the Pacific Southwest!
