The area that is now Sparks was first inhabited by the Washoe people. Euro-American settlement began in the early 1850s, and the population density remained very low until 1904 when the Southern Pacific Railroad built a switch yard and maintenance sheds there, after moving the division point from Wadsworth. In 1902, The Southern Pacific purchased a large tract of swamp-like land near its newly built railyard, and gave everyone clear deed to a 50' x 140' lot for the grand sum of $1. They also offered to pick up and move — free of charge — every house in Wadsworth and reassemble it in this new town.
