Technical Memorandum S of the previous Snake/Salt River Basin Water Plan (Sunrise Engineering and others, 2003) contains a groundwater resource investigation that thoroughly examines the basin’s resources and usage. This Available Groundwater Determination represents the most current assessment of the groundwater resources in the Snake/Salt River Basin, updating and expanding the information presented in the 2003 groundwater investigation. The data contained in this memorandum are a compilation of existing information obtained by several state and federal agencies. While original maps and tables were developed, and existing maps and tables were updated and modified, no original research was conducted for this memorandum.
The format of this update follows the general layout of other, recent groundwater determinations co-authored by the Wyoming State Geological Survey (WSGS) and U.S. Geological Survey (USGS) for the Green River Basin (2010), the Wind/Bighorn River Basin (2012), the Platte River Basin (2013), and the Bear River Basin (2014); this memorandum incorporates much of the content of these four previous studies, frequently without citation.
