History

As the pioneers felt crowded in the new settlements of western Oregon, they turned east to the Columbia Plateau for new opportunities. The county’s first white settler was William Graham, who located at the mouth of the Deschutes River in 1858. Homesteaders, eager for land, arrived in the 1880s by steamboat, stagecoach and wagon. Soon farmers received government patents.

As the population grew, so did the sentiment for independence from Wasco County. Sherman County was created on February 25, 1889, out of the northeast corner of Wasco County. The county’s borders have been changed only once, in 1891, when the Legislative Assembly moved the county line 18 miles (29 km) farther south into Wasco County.

The town of Wasco was designated the county seat by the Legislative Assembly although this designation was contested between Wasco and Moro. Following the addition of a portion of Wasco County, Moro became the eventual winner.
