Scientific Investigations Report 2006–5060
This study was conducted with cooperative funding provided by USGS, Clean Water Services, the Tualatin Valley Water District, and the Cities of Tigard, Hillsboro, Beaverton, Sherwood, Forest Grove, Tualatin, North Plains, Cornelius, and Banks. Tom VanderPlaat (CWS) and Ryan Murdock and Lisa Obermeyer (Montgomery Watson Harza) provided constraints for the pump-back option. We appreciate the helpfulness of Wally Otto (Tualatin Valley Irrigation District), who operates Scoggins Dam, for sharing some of the details of dam operation and helping us to understand the plumbing in Scoggins Dam. We also thank the Bureau of Reclamation, the Joint Water Commission, Clean Water Services, the Oregon Water Resources Department, and all others who contributed data or other details to better frame these model scenarios. Finally we thank Laurel Saito (University of Nevada, Reno), Paul Woods (USGS), Chris Berger (Portland State University), Tom VanderPlaat (CWS), Bryan Horsburgh (Bureau of Reclamation), and Lisa Obermeyer and Ryan Murdock (Montgomery Watson Harza) for their helpful comments from a review of this report.
