Grand Coulee Dam and the Columbia Basin Project, USA

This case study of the Grand Coulee Dam and Columbia Basin Project was completed for the World Commission on Dams, to assist in the completion of their report, “Dams and Development-A New Framework for Decision Making.” The Commission ended in 2001.

“This study is one of eight case studies being undertaken worldwide with a common methodology and approach to inform the World Commission on Dams investigation of the development effectiveness of large dams. This particular case study concerns Grand Coulee Dam (GCD) and the Columbia Basin Project (CBP), which were originally authorised as a single project but today they have come to be known by the two principal parts of the original project. GCD constitutes the dam and powerplant, Lake Roosevelt, and ancillary facilities at the dam. CBP constitutes the project to pump water from Lake Roosevelt to irrigate more than one million acres of land in the semi-arid region in the State of Washington known as the Columbia Plateau.” (Taken from introduction.)
