The authors wish to thank the many municipal public-water suppliers, irrigators, and industrial well owners for their cooperation in providing access to their records. Thanks also to the many smaller public-water suppliers who provided pumpage and population served data. Government agencies and groups such as the Bureau of Reclamation, the Washington State Departments of Ecology and Health, and the Yakama Nation provided valuable support and access to their records during this study.
