Columbia-Pacific Northwest Region

Projects in the Columbia-Pacific Northwest Region

Reclamation's Columbia-Pacific Northwest Region includes the entire U.S. portion of the Columbia River Basin watershed. Since 1904, Congress has authorized 39 projects throughout the region. These projects include 72 dams, dikes, and diversions, and more than 4,700 miles of canals.

In the Pacific Northwest, Reclamation delivers water to 175 irrigation districts. This water is used to irrigate approximately 2.9 million acres with an annual crop value of about $2.2 billion. Annual power production averages 23.8 billion kilowatt-hours of electricity from ten powerplants.
