Topaz Museum in Delta, Utah

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 with the intention of protecting military installations from espionage. One of these camps, then titled Central Utah Relocation Center, was located near Delta and filled with former residents of the San Francisco Bay Area.[8]

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.[9]

A history of the area is kept and displayed at The Great Basin Museum.[10]

Delta experiences a semi-arid climate (Köppen BSk) with hot summers and cold winters. Because of Delta's altitude and aridity, temperatures drop quickly after sunset, especially in the summer. Winters are cold. Daytime highs in the winter are usually above freezing, but nighttime lows drop well below freezing, occasionally falling below 0 °F or −17.8 °C. Delta's climate is similar to that of Salt Lake City, but much more arid.

The Sevier River flows near Delta. The Sevier River is generally used by irrigation before it reaches its eventual end, the dry Sevier Lake.

DMAD are the initials for the Deseret Melville Abraham and Delta water company.

Just upstream of Delta, the Sevier River is dammed to provide irrigation water, reservoir storage, and cooling water for IPP, Intermountain Power Project. This reservoir is referred to as the DMAD.

Agriculture is a major economic force in Delta and the Sevier valley.

Downstream of Delta, the Sevier River is dammed again for irrigation and reservoir storage. This reservoir is named Gunnison Bend Reservoir, in honor of John Williams Gunnison.

One of the main sources of income for Delta is a power plant operated by the Intermountain Power Agency, known as the Intermountain Power Project or I.P.P. It is also referred to as Intermountain Power Service Corporation or I.P.S.C. This coal-powered power plant supplies power for much of Los Angeles county in California. The plant was originally designed for four units, but only two have been built. Each unit produces 950 megawatts of electricity.

Materion's, formerly Brush Wellman, beryllium refining plant is located north of Delta in Millard County. This is one of the few sources of concentrated beryllium in the world. The plant is a mill and finishing facility for beryllium, a high-strength, lightweight metal alloy used in military, aerospace, and medical industries. The ore for the plant is trucked from Materion's mine, located in the Topaz-Spor Mountains, 50 miles west, in Juab County. This is North America's only developed source for the metal. The facility is located here due to the its access to the railway and major highways, 6 and 50.

Alfalfa hay is the main crop of the Delta area. Due to the dry climate in the Delta region, farmers are able to control the moisture content of the hay when it is baled. This is very important to prohibit mold growth.

Delta is home to many dairy farmers who may ship the milk out of the county.

Delta is home to the Lon and Mary Watson Cosmic Ray Center, the main staging area for the Telescope Array Project experiment.[14]

A great attraction of Millard County's economy is the digging of fossils. Trilobite fossils are relatively common in the region west of Delta (part of the House Range's Wheeler Shale). A number of local companies maintain fossil dig areas where they allow visitors to dig their own fossils for a small fee.

Near Delta is a mountain called Topaz Mountain which derives its name from the topaz that is abundant in the area. Other minerals and rocks that are prevalent near Delta include obsidian, opal, and geodes.

Delta South Elementary School is located at 450 South Center Street in Delta, Utah. DSES was originally built in 1982 to accommodate the growth in population due to the construction of the Intermountain Power Plant. The new school was finished in time for the 1983–84 school year and housed grades K-4. In 1989 the fifth grade was moved back to the elementary school. Because of declining enrollment figures, Delta South Elementary was closed in 2009. Delta Early Childhood Center was created using two thirds of the South Elementary building to accommodate preschool and kindergarten students in West Millard County. At the end of the 2014–15 school year, the Delta area schools were reconfigured, placing all of the students in preschool, kindergarten, and first and second grades at Delta South Elementary School.
