From 1911 through 1992 Rio Vista was home to the United States Army Reserve Center, Rio Vista. The facility was initially established as a base for river control activities by the U.S. Army Corps of Engineers. During the 1950s it was used by the U.S. Army Transportation Corps to store and maintain harbor craft, and during the 1960s and 1970s it was used to prepare amphibious vehicles for transportation to Vietnam and to train troops in their use. In 1980 it was transferred to the U.S. Army Reserve and in 1992 it was closed due to a BRAC decision. The town also hosts a United States Coast Guard station, established in 1963.
