The Russian River Watershed (RRW) covers about 1300 square miles (without Santa Rosa Plain) of urban, agricultural, and forested lands in northern Sonoma County and southern Mendocino County, California. Communities in the RRW depend on a combination of Russian River water and groundwater to meet their water-supply demands. Water is used primarily for agricultural irrigation, municipal and private wells supply, and commercial uses - such as for wineries and recreation. Annual rainfall in the RRW is highly variable, making it prone to droughts and flooding from atmospheric river events. In order to better understand surface-water and groundwater issues, the USGS is creating a Coupled Ground-Water and Surface-Water...
The High Plains aquifer extends from approximately 32 to 44 degrees north latitude and 96 degrees 30 minutes to 106 degrees west longitude. The aquifer underlies about 175,000 square miles in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This digital dataset consists of a raster of water-level changes for the High Plains aquifer, predevelopment (about 1950) to 2017. It was created using water-level measurements from 2,928 wells measured in both the predevelopment period (about 1950) and in 2017, the latest available static water level measured in 2013 to 2016 from 63 wells in New Mexico and using other published information on water-level change in areas with few water-level...
Data for groundwater-levels measured in 616 wells during water year 2020 (November 2019-June 2020) by the United States Geological Survey (USGS), the Mojave Water Agency (MWA), and other local water districts were compiled to construct a regional water-table shapefile for 2020. The regional water-table shapefile shows the elevation of the water table in and around the Mojave River and Morongo areas, in San Bernardino County, California.

This data set contains two sets of measured water-level data collected on and near Offutt Air Force Base near Bellevue, Nebraska. Surface-water and groundwater-level data were collected for two synoptic water-level surveys completed in late summer of 2020 and in spring 2021. The elevations of surface-water features were surveyed with a rover receiver using a real-time network (RTN), where the rover receiver receives real-time position corrections from a central server through a mobile wireless-fidelity (Wi-Fi) hotspot linked to the rover receiver. Data collection procedures ensured that positions and elevations achieved a U.S. Geological Survey (USGS) Level-III survey accuracy and surveyed surface-water elevations...

These datasets include wells, springs, and contours used to construct the Hot Springs Highway 270 bypass pre-construction potentiometric-surface map. During the summer of 2017, the U.S. Geological Survey and Hot Springs National Park Service collected groundwater measurements from 66 wells - 59 measurements were used to construct a potentiometric-surface map of wells screened in the Ouachita Mountains aquifer system. The pre-construction potentiometric-surface map provides an early, baseline assessment of groundwater levels and flow directions which will be compared to a later, post-construction groundwater potentiometric-surface map. In addition, comparisons to the pre-construction map will help to identify...
These data include groundwater-level data from 59 wells measured from July to August 2017. Measured groundwater data are also available from the USGS National Water Information System (U.S. Geological Survey, 2018) Well locations were selected from three sources: previously reported sites (Kresse and Hays, 2009), site reconnaissance, and driller’s logs obtained from the Arkansas Natural Resources Commission driller database.

This hydrologic and landscape database was developed by the U.S. Geological Survey, in cooperation with the U.S. Fish and Wildlife Service for the Okefenokee National Wildlife Refuge and contributing watersheds in Florida and Georgia. The database was developed as an assessment and evaluation tool to use in examining refuge-specific hydrologic patterns and trends as related to water availability and water quality for refuge ecosystems, habits, and target species. The database includes hydrologic time series data, statistics on landscape and hydrologic time series data, and hydro-ecological metrics that can be used to assess refuge hydrologic conditions. The database is described in detail in Open File Report 2017-1018.

This dataset contains 50-ft contours for the Hot Springs shallowest unit of the Ouachita Mountains aquifer system potentiometric-surface map. The potentiometric-surface shows altitude at which the water level would have risen in tightly-cased wells and represents synoptic conditions during the summer of 2017. Contours were constructed from 59 water-level measurements measured in selected wells (locations in the well point dataset). Major streams and creeks were selected in the study area from the USGS National Hydrography Dataset (U.S. Geological Survey, 2017), and the spring point dataset with 18 spring altitudes calculated from 10-meter digital elevation model (DEM) data (U.S. Geological Survey, 2015; U.S. Geological...

This data set contains two sets of measured water-level data collected in an area between the Platte and Elkhorn Rivers just above their confluence. Surface-water and groundwater-level data were collected during the fall of 2016 during synoptic water-level survey completed during a low-groundwater demand period and a summer 2017 synoptic water-level survey completed during a high-groundwater demand period. The elevations of surface-water features were surveyed with a rover receiver using a real-time network, where the rover receiver receives real-time position corrections from a central server through a mobile wireless fidelity (Wi-Fi) hotspot linked to the rover receiver. Data collection procedures ensured that...
Ten groundwater piezometers and lake-level stilling wells were deployed in Upper Klamath Lake (UKL), Oregon during May through October 2017. Piezometers and stilling wells were deployed in pairs so that water levels could be measured relative to a common measuring point (MP) at each location. Piezometers were installed in the lakebed sediment, with screens from 3.92 to 4.92 feet below the sediment-water interface (lakebed). Stilling wells were screened open to the lake. Continuous water-level data were collected at nine locations using submerged pressure transducers. One barometric pressure transducer was deployed so that continuous water-level data could be barometrically compensated. Discrete depth-to-water check...
Four boreholes (MW1, MW1UZ, MW2, MW2.1) were drilled in the fall of 2017 and summer of 2018 in upper Redwell Basin, a headwater catchment underlain by hydrothermally altered sedimentary rock in the Elk Mountains near the town of Crested Butte, Colorado. The boreholes were continuously cored using a wireline HQ-sized coring system and sample a combination of Quaternary-aged surficial colluvium and the Cretaceous-aged Mesaverde Formation. In-situ injection-based hydraulic tests were performed in MW1 and MW2 during drilling while advancing using a single-packer apparatus in tandem with an in-line flow meter and interval pressure monitoring. Borehole geophysical logging was performed in MW1, MW1UZ, and MW2.1 in the...

Geochemical data were obtained to investigate the fate and transport of nitrogen in a subterranean estuary near East Falmouth, Massachusetts. The goal of this investigation was to assess nitrogen attenuation in the aquifer under the Eel River Estuary and the adjacent peninsula that was densely populated with residences having septic systems and legacy cesspool inputs of inorganic nitrogen. This estuary is one of many small embayments on Cape Cod where nutrient enrichment can lead to eutrophication and is a major concern for water-quality impairment. Groundwater water-quality data were collected from 3 transects from a total of 27 locations that were sampled between November 2015 and October 2016. Samples were...
The U.S. Geological Survey (USGS) has developed the PRObability of Streamflow PERmanence (PROSPER) model, a GIS raster-based empirical model that provides streamflow permanence probabilities (probabilistic predictions) of a stream channel having year-round flow for any unregulated and minimally-impaired stream channel in the Pacific Northwest region, U.S. The model provides annual predictions for 2004-2016 at a 30-m spatial resolution based on monthly or annually updated values of climatic conditions and static physiographic variables associated with the upstream basin. These values and variables, known as Continuous Parameter Grids, or CPGs, were used as the predictor variables in the model. For purposes of organization,...
This data release documents grid cells and modeled groundwater levels for hydrologic characterization of aquifer areas used for public drinking-water supply in California’s Central Valley from 1990 to 2020. Observations of spring groundwater level (median depth to groundwater measured from January through April) were calculated for selected wells from the California Department of Water Resources (DWR) periodic groundwater level measurements dataset (DWR, 2021) that had data for >50% of years from 1990 to 2020. Spring groundwater levels for years without data were imputed by multiple linear regression on the top five most correlated records within the same Central Valley subregion (Sacramento Valley, San Joaquin...
The U.S. Geological Survey collected groundwater samples from 38 wells used for domestic and small system drinking water supply in the Coachella Valley of California in 2020. The wells were sampled for the Coachella Valley Basin (CODA) Domestic Aquifer Study Unit of the California State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project’s assessment of the quality of groundwater resources used for domestic and small system drinking water supplies. Coachella Valley is located in the Desert hydrogeologic province (Johnson and Belitz, 2003) and is structurally divided into four subbasins by the San Andreas fault: the Indio subbasin, the Mission Creek subbasin,...
