Estimated potentiometric surface by D'Agnese and others (1998), for the Death Valley regional ground-water flow system study, Nevada and California

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. D'Agnese and others (1998) developed a potentiometric surface to conceptualize the regional ground-water flow system and to construct numerical flow models of the Death Valley region, Nevada and California. The estimated potentiometric surface was derived using a gridding algorithm and interactive editing to produce contours representative of the natural water-table conditions. Input data included the altitudes of lakes, springs, and wetlands; water-level [...]
