05 Jul COLUMBIA BASIN PROJECT COMPLETION PROCESS AT A GLANCE
As the Columbia Basin Project (CBP) is the largest Reclamation project in the nation, full development of the authorized 1,029,000 acres was intended to be phased and take multiple decades. Decades since ground breaking on the CBP, it is often asked what it would take to complete the Project. Below, is a high-level overview. Some steps involve multiple years and millions of dollars per step. Construction would require billions of dollars.
