Statewide Water Assessment: Groundwater Levels and Storage Changes

Depiction of the storage change volumes (likely underestimates) of all basins analyzed. We also show the number (N) of wells used to estimate the storage change displayed.

— January 25, 2018

Changes in water levels can reflect very relevant water issues in the arid southwest, such as depletion of the aquifer, variations in nearby surface water, fluctuations in recharge, and changes in the groundwater storage. For this study, we are compiling water level data, in an effort to begin development of a statewide water level change contour map. Fiscal year 2014-2015 was the first year of this effort, where we developed maps showing contours of changes in water levels within 2 select basins (the Mimbres and Estancia Basins). Additionally, we also quantified the change in groundwater storage. The methodology developed for this effort is now being applied for other alluvial basins along the Rio Grande with funding from WRRI for fiscal year 2015-2016.
