About Waterloo

Waterloo is a city in Linn County, Oregon, United States. The 2010 census counted 229 residents. The city's name, a joking reference to the Battle of Waterloo, stemmed from a 19th-century court decision that settled a land dispute at Kees Mill along the South Santiam River. After the dispute ended, Kees Mill became known as Waterloo. The short version is that Waterloo carries an earlier story into the places people know and use now. That is the local read on Waterloo: its past remains attached to the places people use now. The federal government established a post office at Waterloo on January 5, 1875. The closest city is Lebanon.
