A generic, three-dimensional finite-difference model, MODFLOW-2005 (version 1.12.00) and MODPATH-6 (version 6.0.01), was created to better understand the amount of vertical flow and cross-contamination of trichloroethene (TCE) that may be occurring in discontinued extraction wells under current (2018-19) ambient-flow conditions at site 25 of the Edwards Air Force Base, California. The wells are long-screened (100-ft long), contain a surrounding sandpack, and have not been pumped for approximately 10 years. The groundwater flow model utilized multiple observations made from the field measurements of flow and transport to conceptualize, calculate, and simulate in-well flow, and flow in the sand pack. The model was...
The Geneva Industries/Fuhrmann Energy Superfund Site (hereinafter referred to as "the Site") in southeastern Houston, Texas was historically used as a site for petroleum exploration and petrochemical production and is currently (2024) inactive. Previous remedies to clean up the contaminated site included the excavation and off-site disposal of polychlorinated biphenyl (PCB)-contaminated soils, capping the Site and surrounding it with a perimeter slurry wall to contain remaining constituents in the soil and groundwater, the recovery and treatment of trichloroethylene (TCE)-contaminated groundwater, and institutional controls (U.S. Environmental Protection Agency [EPA], 2018). A conceptual site model (CSM) does not...
This data release contains California Department of Water Resources borehole data that were regularized by the US Geological Survey. The dataset contains borehole lithologic data, and geospatial data of water wells in the Hat Creek basin California, located east of Mount Shasta in northern California. The borehole dataset is released as an excel table and a shapefile and includes (1) individual borehole location, and (2) downhole lithologic interval data derived from well drillers’ lithology logs. The geospatial data consists of a point feature class that is a 2-dimensional representation of the locations of Hat Creek basin well logs.

A series of field measurements of surface water velocity derived from video and Doppler velocity radar collected by small unoccupied aircraft systems (sUAS) and portable sensors were collected at seven locations in Colorado, USA, during the summer of 2023. The measurements were utilized to compute surface velocity and discharge using the Probability Concept, Large-Scale Particle Image Velocimetry (LSPIV), and Space-Time Image Velocimetry (STIV) methods. This data release includes the original videos, radar spectra, and ancillary data necessary to produce the surface water velocity and streamflow results. Data are grouped into sections (child items) based on the data type and purpose: Ancillary Scripts: this child...

This data release (DR) is the update of the U.S. Geological Survey - ScienceBase data release Bera (2023), with the processed data for the period October 1, 2021, through September 30, 2022. This data release describes the watershed data management (WDM) database SC22.WDM. The precipitation data are collected from a tipping-bucket rain-gage network and the hydrologic data (stage and discharge) are collected at USGS streamflow-gaging stations in and around Salt Creek watershed in DuPage County, Illinois, as described in Bera (2014). Hourly precipitation and hydrologic data for the period October 1, 2021, through September 30, 2022, are processed following the guidelines described in Bera (2014) and Murphy and Ishii...
This data package documents selected special conditions affecting the magnitude of peak flows at streamgages in Alaska. The data consist of a table of special conditions for selected peak flows and a table of data sources. This dataset resolves ambiguity introduced by historical variations in USGS National Water Information System (NWIS; https://doi.org/10.5066/F7P55KJN) peak-flow code assignment practices or inherent in defining multiple possible conditions for a single code. For peak flows assigned a code 3 or 9 in the NWIS peak-flow database, the special conditions forming the basis for code assignment were (1) snowmelt or (2) a sudden release of water. Sudden releases of water included glacier dammed lake outburst,...
In the dry southwestern United States, snowmelt plays a crucial role as a water source for people, vegetation, and wildlife. However, snow droughts significantly lower snow accumulations, disrupting these critical water supplies for local communities and ecosystems. Despite its large influence on land- and water-resource management, snow drought has only recently been properly defined and its historical distribution and effects on key natural resources are essentially unknown. To remedy this serious knowledge gap, project researchers are examining the causes, effects, and forecastability of snow drought to provide needed scientific information and guidance to planners and decision makers. The central goals of...

This data release contains frequency domain electromagnetic (FDEM) geophysical data collected in fields and forests near and along the banks of the Kankakee River near Hanna, Indiana to observe near surface (top 10 meters or less) electrical conductivity variations, potentially related to soil moisture, lithology, and/or pore fluid conductivity. Both a GEM-2 and a DualEM-421 instrument were used. Raw data, processed inversions (electrical conductivity versus depth), data dictionaries and README files for each instrument are contained in the attached files.
Note: this data release is currently being revised and is temporarily unavailable. This data release contains monthly and annual water-use estimates from the aquaculture and irrigation water-use model (AIWUM) version 1.1 for the Mississippi Alluvial Plain, April 1999 to October 2019. Aquaculture and irrigation estimates contained in this data release are representative of groundwater withdrawal for six different categories: aquaculture, cotton, corn, rice, soybeans, and all other crops. Contained in this data release are monthly and annual estimates by water-use category and monthly and annual total estimates. Monthly and annual totals are a summation of water use for aquaculture, cotton, corn, rice, soybeans,...

The U.S. Geological Survey (USGS), in cooperation with the Washington State Department of Ecology (Ecology), conducted a study to describe the current understanding of the regional groundwater system of the lower Duwamish River valley and groundwater and surface-water interactions in the lower Duwamish Waterway. A nearshore site along the western shoreline of the Duwamish River, about 1.5 mi upstream from the river mouth, was selected for focused groundwater data collection by USGS. Data loggers were deployed in seven groundwater wells and one stilling well in the Duwamish River to measure specific conductance, temperature, and depth at 15-minute intervals for a period of about 2 years.This data release contains...
Salinity levels in streams and tributaries of the Colorado River Basin have been a major concern for years. Recently, the United States Geological Survey’s (USGS) Next Generation Water Observing System (NGWOS) program expanded stream monitoring networks including the number of sites where continuous (15-minute) specific conductance is measured in the Colorado River Headwaters and Gunnison River subbasins located east of the Colorado-Utah state line (hereafter, UCOL). Salinity and total dissolved solids (TDS) can be estimated using specific conductance and water type as a proxy (McCleskey et al., 2023); thus, the UCOL is an ideal basin to apply the proxy. The data presented in this data release, including monitoring...

Forest harvest is one of the primary landscape-scale management actions affecting riparian forests of the Pacific Northwest, U.S, yet the effect of harvest on headwater steam amphibians is largely understudied. Existing information is often limited because of the difficulty separating movement and emigration processes from occupancy and abundance estimates. We designed a before-after control-impact experiment to account for instream movement in the responses of three unique headwater stream amphibians to clearcut logging as part of the Trask River Watershed Experimental Study in the Oregon Coast Range. We captured and marked larval tailed frogs (Ascaphus truei), Coastal giant salamanders (Dicamptodon tenebrosus),...
