These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This digital data set defines the boundary of the area contributing ground-water flow to the Death Valley regional ground-water flow-system (DVRFS) model domain. The boundary encompasses an approximate 112,000 square-kilometer region and was based on a map of regional potential developed by Bedinger and Harrill (2004). Where possible, the amount of lateral flow across the segments of the DVRFS model boundary from (or to) the contributing...
The U.S. Geological Survey (USGS), in cooperation with the Arkansas Geological Survey (AGS), has gathered available geophysical logs and related data from the USGS office archives in Arkansas and Tennessee as a basis for developing a hydrogeologic framework for the Southeast region of the United States. Similar efforts were undertaken by the Mississippi Embayment Regional Aquifer Study (MERAS) and the Regional Aquifer-System Analysis (RASA) Program. The logs compiled for these older efforts were difficult to access from the paper files; however, and partly because of this, older and newer logs were compiled into a single digital database for the current study.

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This digital geospatial data set contains the locations, values, and uncertainties of 700 hydraulic-head observations used in the steady-state, prepumped period of the transient model of the Death Valley regional ground-water flow system (DVRFS), a 100,000-square-kilometer region of southern Nevada and California. Hydraulic-head observations, which are the composite of one or more water-level measurements made at a well, are used...
These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This digital geospatial data set is a compilation of reference points representing springs in California that were used for the regional ground-water potential map by Bedinger and Harrill (2004). The regional ground-water potential map was developed to assess potential interbasin flow in the Death Valley regional ground-water flow system (DVRFS), a 100,000-square-kilometer region of southern Nevada and California. To obtain an adequate...
This Well Completion Report geospatial dataset represents an index to a subset of records available from the California Department of Water Resources' (DWR) Online System for Well Completion Reports (OSWCR). This version of the release contains data from about 255,000 well completion reports (WCRs) for water supply wells from Amador, Butte, Calaveras, Colusa, El Dorado, Glenn, Kern, Kings, Merced, Monterey, Nevada, Placer, Riverside, Sacramento, San Benito, San Bernardino, San Luis Obispo, San Joaquin, Santa Clara, Santa Cruz, Shasta, Stanislaus, Sutter, Tehama, Tulare, and Yuba counties. A subset of WCRs for wells that are not water supply wells also are included. The California Groundwater Ambient Monitoring and...
This data release was prepared as part of an agreement between the California Department of Water Resources (DWR) and the United States Geological Survey (USGS) to support the Sustainable Groundwater Management Act (SGMA). Of the many components of that agreement there is a specific task requiring the Enhancement of Digital Well Completion Reports. Well-completion reports (WCRs) contain information about the wells, such as construction characteristics and lithologic data that is very valuable to SGMA. The data set presented here is a compilation of lithologic information transcribed verbatim from a subset of WCRs contained in DWRs Online System for Well Completion Reports (OSWCR). The format of the lithologic descriptions...

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...

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This digital geospatial data set contains the locations, values, and uncertainties of hydraulic-head observations used in the calibration of the transient model of the Death Valley regional ground-water flow system (DVRFS). The hydraulic-head observations were developed by compositing one or more water-levels measured in wells throughout the DVRFS model domain, a 45,000 square-kilometer region of southern Nevada and California.

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This digital data set defines the boundaries of the deserts of the southwestern United States. Those deserts include the Great Basin, Mojave, Colorado, and Sonoran Deserts as defined by Benson and Darrow (1981). The study by Benson and Darrow (1981) was a historical reference used to support development of the transient ground-water model of Death Valley regional ground-water flow system (DVRFS) completed in 2004 by the USGS (see...

This digital data set defines the lateral boundary of the area simulated by the steady-state ground-water flow model of the Death Valley regional ground-water flow system (DVRFS) by D'Agnese and others (2002). The DVRFS flow model was developed by the U.S. Geological Survey (USGS) for the U.S. Department of Energy (DOE) to support investigations at the Nevada Test Site (NTS) and at Yucca Mountain, Nevada. The model area is an approximately...
This Well Completion Report geospatial dataset represents an index to a subset of records available from the California Department of Water Resources' (DWR) Online System for Well Completion Reports (OSWCR). This release contains water supply well records from Amador, Calaveras, El Dorado, Nevada, Placer, Sacramento, San Bernardino, Sutter, and Yuba counties. The USGS California Water Science Center GAMA project has provided additional attributes: top of open interval; number of open intervals; and various other identifiers such as public supply well number and USGS site number where they can be identified. In some cases, locations are georeferenced to finer resolution based on county APN or 911 geospatial datasets....

This dataset contains 10-foot contours of the 2013 Lower Potomac-Raritan-Magothy aquifer potentiometric surface in the Coastal Plain of New Jersey. The potentiometric-surface contours show altitudes at which water levels would have risen in tightly-cased wells and represent conditions in October 2013 through January 2014. Groundwater-level data from 92 wells cased in, and with the screened interval open to the Lower Potomac-Raritan-Magothy aquifer, were used to construct the potentiometric surface and are publicly available from the U.S. Geological Survey's National Water Information System.
