History of Mattawa

The area where Mattawa is located was first planned out as a town in 1909 by E. and Eva Campbell. However, it wasn't officially a city back then.

The town grew quickly when Priest Rapids Dam and Wanapum Dam were being built nearby. Many construction workers moved to Mattawa. On June 3, 1958, Mattawa officially became an incorporated city. The Port of Mattawa, which helps with trade and shipping, was also started in 1958.

Mattawa is also special because it has the first library in the United States built using straw bales. This unique building was completed in 2002. In 2009, Mattawa changed its government type to become a "non-charter code city." This means it follows general state laws for cities.
