Historical Background

The Dalles has a layered history shaped by Indigenous presence, European exploration, and 19th century expansion. Prior to settlement, Native tribes such as the Wasco and Warm Springs Sahaptin peoples utilized the Columbia River and nearby ecosystems for sustenance and trade. The name The Dalles is thought to derive from the French word dalle, referring to the rock slabs along the river. With the arrival of settlers and the establishment of Fort Dalles in the 1850s, the community grew as a river landing and supply point. Over time, transportation, hydropower, and irrigation projects solidified its position in the regional economy.

Indigenous and Early Contact Period

For centuries, local Indigenous nations managed the lands and waterways around what is now The Dalles. Seasonal fishing, trade networks, and cultural practices were central to community life. With European and American contact, introduced diseases, displacement, and treaty negotiations reshaped population and land use. Federal policies and the creation of Warm Springs and Yakama reservations influenced long-term demographic and economic patterns in the area.
