Washington State University’s Columbia County Extension Office and staff connect the people of Columbia County to the research and knowledge base of the state’s land grant research university. This knowledge base provides solutions to local issues and concerns while stimulating the local economy. Our county-based faculty work with partners in the local communities to provide educational programs and leverage the broad resources of a major university to create a positive future for the residents of Columbia County.

Our local programs include Agriculture, Natural Resources, and 4-H Youth & Families. In addition, Washington State University can supply over 2,200 publications, numerous online educational opportunities, and other statewide educational programs and technical assistance from four Research and Extension Centers, 15 Academic Departments and six of WSU’s Academic Colleges.

WSU and fellow land-grant universities, in 2014, celebrated the 100th anniversary of the federal Smith-Lever Act, which established the Cooperative Extension Service in 1914.

Lewis then became the agricultural agent for only Columbia County from January 1, 1920 until August 20, 1922. Other agricultural agents (county directors) since then include A.Z.
