Spatial Distribution Of Artesian Conditions Within The Niles Cone Basin, Alameda County, California, Anthony Wade Fisher Jan 2017

Spatial Distribution Of Artesian Conditions Within The Niles Cone Basin, Alameda County, California, Anthony Wade Fisher

Master's Theses

The Niles Cone Basin (NCB) within Alameda County, California, contains portions of the basin under perennial and ephemeral artesian groundwater conditions. This study used 349 wells installed throughout the basin’s four-aquifer system to delineate the spatial distribution of the 86 wells that have gone artesian between 1995 and 2015. Artesian wells within all four aquifers occur at elevations below 5.2 meters above sea level (MASL) but predominantly below 3.0 MASL. Even at lower elevations, artesian conditions do not occur in regions of major pumping owing to significant drawdown. Within topographically-low regions, wells may not be artesian where well-heads are located …
