History and general information
Yamhill County was created in 1843 as one of Oregon’s original four districts. Its present boundaries were established in 1860. The county was named after the Yamhelas, members of the Kalapuya Tribe, who lived along the Yamhill River in the western Willamette Valley.
Today, agriculture is still the county’s primary industry. Nursery and greenhouse crops; fruits, nuts, berries; and hay, silage, field and grass seeds are major agricultural products. Yamhill County ranks sixth out of Oregon’s 36 counties in annual market value of its agricultural production. Yamhill County is also the heart of Oregon’s wine industry. Thirty-six wineries represent the largest concentration of wineries in any county and produce the greatest number of award-winning wines in the state. A third of the county is covered with commercial timber. The mainstay of the western valley area is logging and timber products. Nonseasonal industries include a steel rolling mill, electronic and dental equipment manufacturing, an international airline and helicopter company, and a newsprint mill.
