A three-dimensional groundwater flow model, MODFLOW-OWHM, was developed to provide a better understanding of the hydrogeology of the Lucerne Valley Groundwater Basin, California. The model was used to investigate the historical groundwater storage loss and subsidence associated with anthropogenic groundwater demands. The model was calibrated to 1942 through 2016 conditions. This USGS data release contains all of the input and output files for the simulation described in the associated model documentation report https://doi.org/10.3133/sir20225048

This dataset presents the total estimated monthly public-supply water withdrawal by 12-digit hydrologic unit code (HUC12) in the conterminous United States for 2015. Public-supply water use was estimated by spatially and temporally downscaling available data from each state. The total represents combined groundwater and surface water withdrawals for 83,178 watersheds. Public supply refers to water withdrawn by public and private water suppliers that provide water for cities, towns, rural water districts, mobile-home parks, Native American Indian reservations, and military bases. Public-supply facilities are classified under the Standard Industrial Classification (SIC) 4941 and provide water to at least 25 people...

The San Antonio Creek Valley watershed (SACVW) is located in western Santa Barbara County about 15 miles (mi) south of Santa Maria, California and 55 mi north of Santa Barbara, California. The SACVW, is about 140 square miles and encompasses the San Antonio Creek Valley groundwater basin; From the late 1800s, groundwater has been the primary source of water for agricultural, military, municipal, and domestic uses. Groundwater withdrawal from pumping has exceeded the amount of water replenishing the basin, causing groundwater declines of more than 150 feet in parts of the valley between 1943 and 2017, and reducing base flow in San Antonio Creek at the western end of the SACVW. Agricultural water use (primarily for...

Infiltrometers are devices used to measure the infiltration rates of water into soils or porous media (Bouwer, 1986). Cylinder infiltrometers are generally constructed from metal shaped into cylinders which are driven into the ground and flooded with water. The rate at which water infiltrates into the ground is measured until the rate of infiltration is constant to capture unsaturated infiltration rates and beyond steady state to measure saturated infiltration rates and conductivity (Bouwer, 1986). Infiltrometers are typically employed to measure the rate of infiltration on inundated soils such as surface irrigation, seepage from surface water such as streams or reservoirs, or infiltration basins for groundwater...

Pneumatic and traditional (physical) slug tests are presented for monitoring wells in Hinkley Valley, California, 2015-2017. Data were collected in support of a U.S. Geological Survey study on background concentrations of hexavalent chromium.
