Federal Columbia River Power System
Cultural Resource Program
​​​The Columbia and Snake Rivers cleave through thousands of years of history, shaping cultures and communities throughout the Pacific Northwest region. Traces of this history remain along the banks of our region's rivers in the form of archaeological and traditional cultural sites that continue to be important to living communities today.
Operation and maintenance of 14 federally owned dams that are part of the Federal Columbia River Power System (FCRPS) affect these traces of our history by causing erosion that washes away archaeological sites, and by limiting Native Americans’ access to traditional village sites, legendary sites that hold stories about tribal history, and important natural resource gathering areas.

Section 106 of the National Historic Preservation Act (NHPA) requires Federal Agencies to consider the effects of their actions on "historic properties", which are the physical traces of our nation's history considered to be "significant". When a historic property is negatively affected by a federal action, agencies must develop management strategies to protect the property or to mitigate for those effects.
In order to effectively manage historic properties, the FCRPS Cultural Resource Program (Program) was created in 1997 as a jointly-administered effort overseen by the U.S. Army Corps of Engineers, the Bureau of Reclamation, and Bonneville Power Administration to address NHPA section 106 compliance. Work is guided by a programmatic agreement for management of historic properties affected by the operation and maintenance of the FCRPS.
The Program is also a partnership with state, tribal, and federal technical staffs that participate in Cultural Resource Cooperating Groups. Together, specialists in Columbia River Plateau archaeology and cultural resources share information and develop creative solutions in the management of cultural resources within the FCRPS.
