Delta's  unique geographical setting and its rich history create a strong sense of place and a special community character. Located at the confluence of the Uncompahgre and Gunnison Rivers, Delta is well situated at the crossroads of US 50 and State Highway 92. It is the gateway to the Gunnison River Valley and the rich agricultural lands located adjacent to Paonia, Hotchkiss, and the slopes of the Grand Mesa.
Considered the first identifiable human inhabitants of the region, the Fremont people traversed the valley during hunting and gathering trips and cultivated crops such as corn, squash and beans. After the Fremont disappeared around 1200 A.D., Ute bands, who were primarily hunters and gatherers attracted by the mild winters and proximity to abundant game, became the primary residents of the area. The Utes remained the dominant inhabitants until they were forcefully removed to Indian reservations in southwest Colorado and northeast Utah.
The Delta area was recognized by early settlers as a favorable location for fruit growing and other agriculture. A flourishing agricultural industry emerged at the east end of the valley as water was diverted from the Gunnison and Uncompahgre Rivers to fill the extensive network of ditches and canals.
Railroads were completed through Delta in 1890, providing easy access for local growers. Refrigerated railroad cars were the primary transportation method for shipping fruit until the late 1970s when truck transport became dominant.
Coal mining has played a significant role in the history of the Delta area. The Somerset mine area ships coal to the nation by rail which runs through Delta.
