Eldorado Center, on Farm Road 638 twenty miles southwest of Corsicana in southwestern Navarro County, began as a settlement for workers on the large Eldorado Ranch. The area was first settled before the Civil War, but the first business, a grocery store, was not established until about 1910. A school was in operation at Eldorado by the early 1900s, and in 1906 it had an enrollment of forty-eight. At its height around the time of World War I Eldorado Center had a number of houses, a church, a school, a cotton gin, and a store. By the mid-1930s only a store and a number of houses remained there. The community's estimated population in 1936 was fifty. The store closed after World War II, and in the mid-1960s only a few widely scattered houses remained in the area. In the early 1990s Eldorado Center was a dispersed rural community. In 2000 the population was twenty.
