History

Delta was originally a railroad switch called Aiken. In 1905 Aiken was renamed Melville when Millard County began plans to set up irrigation and a dam. People purchased land for 50 cents an acre as long as they agreed to develop a 40-acre lot. The name was changed again because of the similarities between Melville and Millville, another town in Utah. The name was changed on 12 May 1908 to Burtner. The name was finally changed to Delta on May 11, 1911. The name is quite fitting as the area was a delta of the Sevier River.

Topaz Relocation Camp

During World War II, after the attack on Pearl Harbor, tens of thousands of Japanese-Americans were gathered up and placed in 10 incarceration camps to protect military installations from espionage. One of these camps, then entitled Central Utah Relocation Center, was located near Delta and filled with former residents of the San Francisco Bay Area.

The Topaz Museum, located in Delta, works to preserve important sites at the relocation center and to provide information on the history of the camps.
