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 …
