Things to Do in Dayton

History of Dayton

The City of Dayton was founded in the 1860’s by Elizabeth and Jesse Day.  Today it is the County Seat of Columbia County and has the oldest train depot and continuously operating courthouse in the State of Washington, both dating back to the late 1880’s.

The population remains at about 2,500, though in previous years there were more seasonal migrant workers that cut asparagus for Green Gian,t and who built the Little Goose Lock and Dam northeast of Starbuck.
