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

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 data from wells; and hydrogeologic information pertaining to areas of recharge, discharge, and low- permeability rocks
