Hualapai Valley Basin\nis a broad, internally drained, intermountain desert basin in Mohave County, northwestern \nArizona. Basin-fill aquifers are the primary groundwater source for many desert communities, \nand the residents, commerce, and agriculture in and near to the Hualapai Valley Basin must \nrely on such groundwater to meet water needs. As in many parts of the western United States, \npopulation growth in this part of Arizona is substantial. From 2000 to 2018 the population of the \nCity of Kingman, Arizona, grew from 20,069 to 30,314, an increase of 51 percent, whereas the \npopulation of Mohave County grew from 155,062 to 209,550, an increase of 35 percent.  Water \nmanagers in Mohave County have raised concern about the potential for future groundwater \ndevelopment and additional stresses on the groundwater system in the Hualapai Valley Basin. \nIn particular, the City of Kingman, Ariz., water supply is primarily groundwater withdrawn from \nthe Kingman subbasin of the Hualapai Valley Basin, northeast of the city. The potential effects \nof future water development on the City of Kingman well field have become a top concern to \nregional water-resource managers.  To address these concerns the Hualapai Valley Hydrologic \nModel (HVHM) simulates the hydrologic system for the years 1935 through 2219, including \nfuture withdrawal scenarios that simulate large-scale agricultural expansion with and without \nenhanced groundwater recharge from potential new infiltration basin projects. HVHM is a highly \nparameterized model (75,586 adjustable parameters) capable of simulating grid-scale variability \nin aquifer properties (for example, conductivity, specific yield, and specific storage) and system \nstresses (for instance, natural recharge and groundwater withdrawals). System stresses were \npartially adopted from a previously-published groundwater model (Tillman and others, 2013). \nParameter estimation and uncertainty quantification were performed using an iterative ensemble \nsmoother software (PESTPP-IES) to produce an ensemble of models fit to historical data. Two \nfuture scenarios were simulated with a subset of the posterior parameter ensemble comprising \nthe 40 best-fit realizations. In scenario 1, future pumping was simulated to increase linearly from \n2019 through 2029 and then held constant through 2219. Scenario 2 includes the same specified \nfuture pumping, but also simulates enhanced recharge at proposed infiltration basins throughout \nthe Kingman subbasin beginning in 2019.
