Hermiston History
Hermiston’s history is closely tied to irrigation and agriculture.
At the beginning of the twentieth century, the area was largely sagebrush-covered land. Local promoters believed irrigation could make the region suitable for farming. A townsite was platted in 1904, and the town was incorporated in 1907.
The name Hermiston has an unusual connection to literature.
J. F. McNaught named the town after Robert Louis Stevenson’s unfinished novel Weir of Hermiston. The suggestion came from McNaught’s wife, Jennie.
The development of the Umatilla Irrigation Project then changed the area’s future. Water was diverted to farmland, allowing farmers to produce crops on a larger scale. Early agricultural products included wheat, peas, and potatoes.
Later, the Umatilla Army Depot and McNary Dam brought additional economic activity and population growth to the region.
Hermiston and Agriculture
Agriculture remains one of the most important parts of Hermiston’s identity.
The region’s irrigation systems helped support large-scale farming. Today, Hermiston and the surrounding Columbia Basin are associated with:
- Watermelons
- Potatoes
- Onions
- Wheat
- Corn
- Fruits and vegetables
- Food processing
- Agricultural distribution
Hermiston’s warm summers are especially important for melon production. Local farms have built a strong reputation for the area’s watermelons, making the fruit part of the city’s identity.
This agricultural connection also explains why farm stands and seasonal produce are common parts of the local visitor experience.
Hermiston and the Columbia River
The Columbia River plays an important role in the region’s geography, economy, and recreation.
Hermiston is located close to the river, with communities such as Umatilla and Boardman nearby. The river provides opportunities for boating, fishing, wildlife viewing, and other outdoor activities.
It has also influenced transportation and agriculture.
The combination of river access, railroads, highways, and irrigation has helped Hermiston develop into a regional transportation and agricultural center.
