support of this project. First, Professor Richard E. Toth, of the Department of Environment and Society, served as my committee chair and was integral throughout this project, offering both insight and advice. Karin M. Kettenring and Joseph Wheaton, both of the Department of Watershed Sciences, also served as committee members and provided valuable guidance and support. I would also like to thank Fee Busby for his assistance during the development of this study. And without the aid of Becky Hirst and Tracy Jones this project would not have been possible. Aside from University staff, I would like to thank the Utah Division of Water Resources for answering my many questions and providing literature for review. Lynn de Freitas from the Friends of the Great Salt Lake also provided valuable information about the lake and insight into additional resources. I will be forever indebted the many friends who were willing to give of their time by reviewing and providing feedback on this report. As well as assisting me in other areas of my life while I worked six days a week researching, writing, and building models for this project. I would also like to thank my amazing wife Stephanie for without her tireless efforts and patience I would never have been able to complete this project. Lastly I would like to thank my son Parker, for providing me with inspiration and motivation throughout this entire process. iii Preface The following bioregional planning study is a direct result of the 2009- 2010 studio project initiated by the United States Fish and Wildlife Service (FWS). The FWS contacted the study team and asked them to determine how the future growth and development of the Bear River Watershed would impact the Bear River Migratory Bird Refuge (BRMBR). The study looked at all of the physical and biophysical systems within the Bear River Watershed to identify the issues that had an effect on the BRMBR. It became apparent from the original project that the future of the BRMBR and other Great Salt Lake wetlands was dependent upon the future use of water within the Bear River Watershed and the Great Salt Lake Watershed as a whole. Further research uncovered significant proposed withdrawals to the tributaries of the Great Salt Lake as well as some directly from the lake itself. After discussions with multiple stakeholders that rely on water from Great Salt Lake tributaries and water from the lake, it became clear that there was a need for a study to determine how the proposed future use of water within the Great Salt Lake Watershed would affect the wetlands that border the lake. It is the goal of this study to determine how the future
