History and General Information
Yamhill County was one of Oregon’s original four districts. It was created in 1843, but its current 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.
Agriculture is still the county’s primary industry. Nursery and greenhouse crops; fruit trees, nuts, wine grapes, berries, hay, silage, field and grass seeds are major agricultural products. Yamhill County ranks sixth among the counties in annual market value of its agricultural production. It is also the heart of Oregon’s wine industry. Over 80 wineries and 200 vineyards represent the largest concentration of wine growers and producers in any county in the state. One-third of the county is covered with commercial timber. The mainstay of the western valley area is logging and timber products. Yamhill County produces everything from snack foods to rebar, timber products to plastic tubing, and textiles to dental equipment.
