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 …
