History 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. Deer Creek
