History and General Information
Morrow County, created from Umatilla County in 1885, is located east of the Cascades in north-central Oregon. It was named for J. L. Morrow, an early resident. Morrow County contains more than one million acres of gently rolling plains and broad plateaus. This rich agricultural land can be roughly divided into three occupational zones—increasing amounts of irrigation farming in the north, vast fields of wheat yielding to cattle ranches in the center, and timber products in the south. With the advent of center pivot irrigation technology,
Morrow County became one of Oregon’s fastest growing areas in terms of population, personal income, and agricultural and industrial development. The Port of Morrow, second largest in the state in terms of tonnage, serves as a gateway to the Pacific Northwest and Pacific Rim markets.
