Download or read book Geology and Ground-water Chemistry, Curlew Valley, Northwestern Utah and South-Central Idaho, Implications for Hydrogeology written by Hugh A. Hurlow and published by Utah Geological Survey. This book was released on 2008 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report (185 pages and 2 plates) presents new and compiled geologic, geophysical, hydrologic, and hydrochemical data to delineate the regional ground-water flow system in Curlew Valley. Decreased precipitation combined with increased agricultural pumping in the central part of Curlew Valley since the late 1960s caused a steady decline in discharge at the Locomotive Springs complex. The report includes a compiled geologic map of the Curlew Valley surface-drainage basin at 1:100,000 scale and new geologic and hydrochemical data.
